We’ll demystify what an arbor size is, why it’s absolutely critical, and how to ensure you always pick the perfect blade for your WEN tool.

By the end of this guide, you’ll understand the intricacies of blade compatibility, learn how to avoid common pitfalls, and gain the confidence to select the right accessories for flawless results every time. Let’s make sure your next cut is your best cut!

Understanding Your WEN Track Saw Arbor Size

Before you even think about buying a new blade, you need to know the core specification: the arbor size. This isn’t just a number; it’s the diameter of the hole in the center of your saw blade that fits onto the arbor shaft of your track saw.

For most WEN track saws, like the popular CT1065 model, the standard wen track saw arbor size is 20mm. This is a common size for many track saws, differentiating them from standard circular saws which often use a 5/8-inch arbor.

Why the difference? Track saws are designed for high-precision, low-kerf cutting, and their engineering often necessitates specific blade dimensions for optimal performance and integration with the saw’s unique motor and dust collection systems.

What is an Arbor, Anyway?

Think of the arbor as the axle on your saw. It’s the rotating shaft that the saw blade mounts onto. The blade then spins around this shaft, driven by the saw’s motor.

The arbor has a specific diameter, and the hole in your blade must match this diameter perfectly. If it’s too small, the blade won’t fit. If it’s too large, the blade will wobble, leading to inaccurate cuts and a very dangerous situation.

Locating Your WEN Track Saw’s Arbor Size

The most reliable way to confirm your specific wen track saw arbor size is to consult your saw’s user manual. It will clearly state the required blade specifications, including the arbor diameter.

If you don’t have the manual, you can often find this information on the WEN website for your specific model number. As a last resort, you can carefully measure the arbor shaft itself, but always prioritize the manufacturer’s documentation.

Why Arbor Size Matters: Precision and Safety

The arbor size might seem like a minor detail, but it’s paramount for both the quality of your work and your personal safety. Getting this wrong can have significant consequences.

Achieving Optimal Precision

A blade with the correct arbor size will sit snugly on the saw’s arbor shaft. This tight fit ensures the blade spins true, without any wobble or runout.

  • Straight Cuts: A true-spinning blade makes perfectly straight cuts along your track.
  • Clean Edges: No wobble means less friction, less burning, and cleaner, splinter-free edges.
  • Consistent Depth: The blade maintains its set depth throughout the cut, crucial for dadoes or precise rabbets.

Even a tiny bit of play between the blade and the arbor can translate into noticeable imperfections in your workpiece, undoing all the benefits of using a track saw in the first place.

Ensuring Safe Operation

This is where correct arbor size moves from “important” to “critical.” A blade that doesn’t fit properly is a serious safety hazard.

  • Blade Wobble: An ill-fitting blade will wobble excessively, increasing the risk of kickback.
  • Blade Slippage: If the arbor hole is too large, the blade might not be properly secured, potentially slipping or coming loose during operation.
  • Increased Vibration: Excessive vibration not only makes the saw harder to control but also puts undue stress on the saw’s motor and bearings, leading to premature wear.
  • Projectile Risk: In extreme cases, a loose blade could become a projectile, causing severe injury.

Always prioritize safety. Never attempt to force a blade that doesn’t fit, and never use shims or adapters unless they are specifically designed and approved by the manufacturer for your tool.

Decoding Blade Specifications: Beyond the Arbor

While the wen track saw arbor size is your first consideration, it’s just one piece of the puzzle. Track saw blades have several other specifications that impact their performance.

Blade Diameter

WEN track saws typically use a 6.5-inch (165mm) blade. Just like arbor size, using the correct diameter is essential for proper saw function, depth of cut, and maintaining blade guard clearance.

Tooth Count (TPI – Teeth Per Inch)

The number of teeth on a blade dictates the type of cut it makes:

  • Fewer Teeth (24T-32T): Ideal for fast ripping of solid wood. Leaves a rougher finish.
  • Medium Teeth (48T-60T): A good all-around blade for cross-cutting solid wood and general-purpose plywood/MDF work.
  • More Teeth (60T-80T): Excellent for fine cross-cuts, cutting laminates, melamine, and plywood where a super clean finish is paramount.

For most track saw users, a 48T or 60T blade is a versatile choice, offering a great balance of speed and finish.

Kerf Width

Kerf is the thickness of the cut made by the blade. Track saw blades often have a thin kerf (e.g., 2.2mm or 2.5mm) to reduce material waste and motor strain.

A thinner kerf also means less material is removed, which can be beneficial when working with expensive hardwoods or sheet goods. Always ensure your saw’s splitting wedge (riving knife) is compatible with your blade’s kerf width.

Tooth Geometry

Different tooth grinds are designed for specific tasks:

  • ATB (Alternate Top Bevel): Standard for general-purpose work, good for cross-cutting and some ripping.
  • FTG (Flat Top Grind): Best for ripping solid wood.
  • TCG (Triple Chip Grind): Excellent for cutting laminates, melamine, and non-ferrous metals, providing very clean cuts and long life in abrasive materials.

Most track saw blades come with an ATB or a modified ATB (like Hi-ATB) for clean cuts on sheet goods.

Choosing the Right Blade: A Wen Track Saw Arbor Size Guide

Now that you understand the key specifications, let’s walk through the process of selecting the perfect blade for your WEN track saw.

  1. Confirm Your Saw’s Requirements:
    • Check your WEN track saw manual for the exact blade diameter and, most importantly, the wen track saw arbor size (e.g., 165mm diameter, 20mm arbor).
    • Note any specific kerf width requirements for your saw’s riving knife.
  2. Identify Your Primary Use:
    • Are you mostly cutting plywood and MDF for cabinets? A 48T-60T ATB blade is great.
    • Need to rip long boards of hardwood? A 24T-32T blade might be faster, but ensure it’s rated for track saw use.
    • Working with delicate veneers or melamine? A 60T-80T TCG or Hi-ATB blade will provide the cleanest edge.
  3. Research Blade Options:
    • Look for blades specifically labeled “track saw blade” or “plunge saw blade.”
    • Popular brands like Freud, Diablo, Oshlun, and of course, WEN itself, offer compatible blades.
  4. Verify All Specifications:
    • Before purchasing, double-check that the blade’s diameter, arbor size, tooth count, and kerf all match your saw’s requirements and your project needs.

Remember, investing in a high-quality blade is just as important as having a good saw. A cheap blade, even with the correct arbor size, can quickly dull, burn wood, and deliver subpar results.

Installation and Maintenance: Wen Track Saw Arbor Size Best Practices

Proper installation and routine maintenance are crucial for extending the life of your blades and ensuring consistent, safe operation.

Safe Blade Installation

Changing a track saw blade is a straightforward process, but it requires careful attention to safety.

  1. Unplug Your Saw: Always, always, always unplug your WEN track saw from the power outlet before performing any maintenance or blade changes.
  2. Access the Arbor: Most WEN track saws have a blade lock button and a hex wrench for removing the arbor bolt. Engage the blade lock.
  3. Loosen the Arbor Bolt: Use the provided wrench to loosen the arbor bolt. Remember, it’s often a reverse thread, meaning you turn it clockwise to loosen and counter-clockwise to tighten. Check your manual!
  4. Remove Old Blade: Carefully remove the old blade, noting the direction of the teeth.
  5. Clean the Arbor: Use a brush or cloth to clean any sawdust or debris from the arbor shaft and blade washers. A clean surface ensures a true fit.
  6. Install New Blade: Place the new blade onto the arbor, ensuring the teeth are pointing in the correct direction (usually indicated by an arrow on the blade or saw). The wen track saw arbor size must match the blade’s hole perfectly.
  7. Secure the Blade: Replace the blade washer and arbor bolt. Tighten the bolt firmly with the wrench, but do not overtighten, as this can strip threads or warp the blade.
  8. Check for Play: Gently try to wiggle the blade. There should be no play.
  9. Test Spin: Plug in the saw and briefly run it in a safe area to ensure the blade spins smoothly without wobble or excessive vibration.

Blade Care for Longevity

A little care goes a long way in preserving your blades and getting the most out of your investment. This is part of a comprehensive wen track saw arbor size care guide.

  • Clean Regularly: Sawdust and resin buildup on blade teeth and sides can cause friction, burning, and dulling. Use a dedicated blade cleaner (like a resin remover) and a brush to keep your blades pristine.
  • Store Properly: Store blades flat or in protective sleeves to prevent damage to the delicate carbide teeth. Avoid tossing them into a drawer where they can chip against other tools.
  • Avoid Overheating: Don’t force your saw through material. Let the blade do the work. Overheating can damage the carbide tips and warp the blade.
  • Sharpen When Dull: A dull blade is inefficient and dangerous. When you notice burning, splintering, or increased effort to push the saw, it’s time for sharpening. Find a reputable saw blade sharpening service.

Troubleshooting Common Problems with Your Track Saw Blade

Even with the right wen track saw arbor size and a quality blade, you might encounter issues. Here are some common problems and how to address them.

Blade Wobble or Excessive Vibration

This is a red flag for safety and cut quality. If your blade wobbles:

  • Check Arbor Fit: Re-confirm that the blade’s arbor hole perfectly matches your saw’s arbor size.
  • Inspect Blade: Look for any signs of warping, damage, or missing teeth on the blade itself. A damaged blade must be replaced.
  • Clean Components: Ensure the arbor shaft, blade washers, and blade itself are free of sawdust and debris that could prevent a flush fit.
  • Tighten Arbor Bolt: Make sure the arbor bolt is securely tightened.
  • Inspect Saw Arbor: In rare cases, the saw’s arbor shaft itself could be bent or damaged. If everything else checks out, this might require professional service.

Burning or Scorching the Wood

If your blade is leaving burn marks, consider these points:

  • Dull Blade: The most common culprit. A dull blade generates more friction. Sharpen or replace it.
  • Resin Buildup: Clean the blade thoroughly with a resin remover.
  • Incorrect Tooth Count: Using a blade with too few teeth for a fine cut (e.g., a 24T ripping blade for cross-cutting plywood) can lead to burning.
  • Feed Rate: You might be pushing the saw too slowly, allowing the blade to rub rather than cut cleanly. Maintain a consistent, steady feed rate.
  • Blade Set: If the teeth aren’t properly “set” (bent slightly outward), the blade body can rub against the wood. This is usually a manufacturing or sharpening issue.

Excessive Splintering or Tear-Out

Track saws are designed to minimize tear-out, so if you’re experiencing it, something’s amiss.

  • Dull Blade: Again, a dull blade is a primary cause.
  • Wrong Tooth Count: For sheet goods, a higher tooth count (48T-60T+) is usually best.
  • Scoring Function: Ensure your WEN track saw’s scoring function (if it has one) is properly adjusted and engaged. This makes a shallow cut first to prevent splintering.
  • Depth of Cut: Ensure the blade is set to cut just through the material, plus maybe an eighth of an inch. Too shallow or too deep can sometimes affect tear-out.
  • Track Placement: Make sure your track is firmly clamped and positioned correctly, with the anti-splinter strip aligned with your cut line.
  • Material Support: Ensure the material is fully supported underneath the cut to prevent flexing and tear-out.

Sustainable Choices: Eco-Friendly Blades and Practices

As woodworkers, we often think about the impact of our material choices, but our tools and consumables also play a role. Making sustainable choices for your wen track saw arbor size blades can be part of an eco-conscious workshop.

Extending Blade Life

The most eco-friendly blade is the one you already own. By following the wen track saw arbor size care guide practices mentioned earlier, you significantly reduce waste.

  • Regular Cleaning: Keeps blades efficient, reducing strain on the motor and extending blade life.
  • Professional Sharpening: Instead of tossing a dull blade, have it professionally sharpened. A good carbide blade can be sharpened many times, saving resources and money.
  • Proper Storage: Prevents accidental damage that would necessitate early replacement.

Choosing Durable, Recyclable Materials

When you do need new blades:

  • Carbide-Tipped Blades: These last significantly longer than steel blades, reducing the frequency of replacement.
  • Recyclable Materials: While blades aren’t typically curbside recyclable, some metal recycling centers may accept them. Check with local facilities.
  • Support Manufacturers with Sustainable Practices: Research brands that prioritize eco-friendly manufacturing processes, responsible sourcing of materials, and packaging.

By consciously choosing to maintain your tools and making informed purchasing decisions, you contribute to a more sustainable woodworking practice.
