The CMT ITK Fine Finish Saw Blade - 10 inch x 5/8 in. - 40 Tooth ATB is a general-purpose circular saw blade engineered for clean, accurate cuts in a wide range of wood and engineered wood products. Designed to fit corded circular saws, cordless circular saws, and miter saws, this blade handles hardwood, softwood, OSB, pressure-treated lumber, and laminated beams with consistent results. The 40-tooth Alternate Top Bevel grind at 15 deg. produces smooth finish cuts whether you are crosscutting framing lumber or ripping through hardwood panels. With a kerf of 0.110 in. and a plate thickness of 0.071 in., this blade maintains a stable cutting path while minimizing material waste.

Key Features

• 40-Tooth ATB 15 deg. Grind - the Alternate Top Bevel tooth geometry at 15 deg. shears wood fibers cleanly on both crosscuts and rip cuts, leaving a fine, splinter-reduced finish in hardwood and softwood alike.
• Tri-Metal Brazing (Silver-Copper-Silver) - the special tri-metal brazing process bonds carbide teeth with exceptional strength, allowing them to handle high stress and impact when cutting harder woods and composite materials without tooth loss.
• Precision Blade Body Flatness - the blade body is flattened through special straightening processes that guarantee exceptionally reduced tolerances, so the blade tracks true and delivers consistent, accurate cuts from the first pass to the last.
• Full Blade Balancing - every blade undergoes balancing during production, which guarantees maximum stability at operating speeds and reduces vibration that could otherwise cause wandering cuts or premature wear on your saw.
• HW Carbide Tooth Material - hard metal carbide teeth retain their edge longer through repeated cuts in dense hardwoods, laminated beams, and pressure-treated lumber, reducing the frequency of blade changes on the job.
• 5/8 in. Bore Diameter - the standard 5/8 in. arbor bore fits the most common corded and cordless circular saws and miter saws, making swaps and setups fast and straightforward.
• 7600 Maximum RPM Rating - rated for up to 7600 RPM, this blade keeps pace with high-speed saw motors without exceeding safe operating limits, giving you confidence at full tool power.
• 0.110 in. Kerf / 0.071 in. Plate - the combination of a thin plate and controlled kerf width reduces cutting resistance, which is especially valuable when running on cordless saws where battery efficiency matters.

Why This Product

• If you need one blade that moves between a cordless circular saw, a corded circular saw, and a miter saw without swapping setups, the standard 5/8 in. bore and 7600 RPM rating make this blade a versatile fit across all three machine types.
• The Tri-Metal Silver-Copper-Silver brazing is specifically engineered to withstand the elevated stress of cutting harder woods and composite materials, making this a reliable choice when your material list includes laminated beams and pressure-treated lumber alongside standard framing stock.
• For finish carpentry and millwork where a clean edge matters, the 40-tooth ATB geometry at 15 deg. produces a smooth cut face that reduces sanding and cleanup time compared to coarser general-purpose blades.
• The combination of precision blade-body straightening and full balancing means you get maximum stability and reduced runout - practical advantages that translate directly into straighter cuts and longer bearing life on your saw.

Frequently Asked Questions

What machines is this blade compatible with?

This blade is designed to fit cordless circular saws, corded circular saws, and miter saws. The standard 5/8 in. (15.88 mm) bore diameter matches the arbor size found on the majority of 10 in. saws in those categories.

What is the maximum safe operating speed for this blade?

This blade is rated for a maximum of 7600 RPM. Always confirm that your saw's no-load RPM does not exceed this rating before mounting the blade.

What does ATB mean and why does it matter for my cuts?

ATB stands for Alternate Top Bevel. On this blade, every other tooth is beveled in the opposite direction at 15 deg. This geometry slices wood fibers from both sides of the kerf, which produces a cleaner, smoother cut face - particularly useful when cutting hardwood, softwood, and laminated materials where a fine finish is important.

What materials can this blade cut?

This blade is designed to cut hardwood, softwood, OSB, pressure-treated lumber, and laminated beams. The hard metal carbide teeth and Tri-Metal brazing are specifically chosen to handle the added stress of denser and composite wood materials.
