CMT ITK-Plus Finish Blade 7-1/4 in. x 5/8 in. - 40-Tooth ATB+Shear - 10-Pack is a professional-grade circular saw blade engineered for smooth, splinter-free cuts in wood, plywood, OSB, and hardboard. Featuring a 40-tooth Alternate Top Bevel with Shear (ATB+S) grind and an 18 deg. cutting angle, this finish blade delivers the precision edge quality demanded by contractors and finish carpenters working with cordless circular saws and portable table saws. This bulk 10-pack format is ideal for crews and high-volume jobsites where consistent, quality finish cutting is a daily requirement.

Key Features

• 40-Tooth ATB+Shear Grind (10 ATB+S) - the combination of Alternate Top Bevel geometry and a shear component slices wood fibers cleanly rather than tearing them, resulting in smooth finish-quality edges in wood, plywood, OSB, and hardboard with minimal sanding required.
• 18 deg. Cutting Angle - an aggressive hook angle drives the blade through material efficiently on cordless circular saws and portable table saws, reducing motor strain and helping maintain consistent cut quality even as battery power varies.
• 7-1/4 in. Diameter with 5/8 in. Bore (15.88mm) - matches the most common circular saw arbor size, making these blades a direct drop-in fit for the widest range of portable circular saws and job-site table saws without adapters.
• 0.069 in. Kerf Thickness - a full-kerf tooth profile provides a stable, chatter-free cut path and is well-suited to the rigidity demands of finish and trim cutting applications.
• 0.043 in. Plate Thickness - a thinner plate behind the full kerf means less material removed per pass, reducing waste and heat buildup for extended cutting sessions.
• Hard Metal (HW) Carbide Tips - tungsten carbide tooth material maintains a sharp, durable edge through repeated use in hardwood, softwood, engineered panel, and composite sheet material applications.
• Maximum 8,300 RPM Rating - rated to handle the higher no-load speeds of modern cordless circular saws, so the blade remains safe and effective across a full range of compatible machines.
• 10-Piece Bulk Masterpack - stocking up with a 10-pack ensures continuous workflow on multi-crew jobsites and reduces per-blade cost compared to purchasing individually.

Why This Product

• Engineered for cordless circular saws and portable table saws - the 8,300 RPM maximum rating and ATB+Shear tooth geometry are specifically matched to the variable power output and high-speed motors found in today's cordless and job-site portable saws, giving finish carpenters a blade that works with their tools rather than against them.
• Finish-quality results on a wide range of sheet materials - the 40-tooth ATB+S configuration is recommended for wood, plywood, OSB, and hardboard, making this a single versatile blade choice for trim, cabinetry, sheathing, and general finish carpentry tasks on the same jobsite.
• Bulk 10-pack value for contractors and crews - having 10 identical blades on hand eliminates downtime caused by worn blades, keeps multiple saws running simultaneously, and maintains cut consistency from the first blade to the last across a project.
• Full-kerf stability at a controlled plate thickness - the 0.069 in. kerf paired with the 0.043 in. plate delivers a cut path that is wide enough to resist pinching and binding in dense sheet goods while still managing heat and material waste during extended use.

Frequently Asked Questions

What does ATB+Shear tooth geometry mean and why does it matter for finish cuts?

ATB+S stands for Alternate Top Bevel plus Shear. Each tooth is ground at an alternating bevel angle, and the shear component adds a slicing action as the tooth enters the material. Together, this geometry severs wood fibers cleanly rather than tearing them, which is why this blade is specifically recommended for finish cutting applications in wood, plywood, OSB, and hardboard where surface quality matters.

Is this blade compatible with my cordless circular saw?

This blade is designed for use with cordless circular saws and portable table saws. Its 7-1/4 in. diameter and 5/8 in. bore fit the most common arbor size on these machines. Blade diameter compatibility is contingent on the specific machine type, so confirm your saw accepts a 7-1/4 in. blade and a 5/8 in. arbor before installing. The 8,300 RPM maximum rating is suited to the high no-load speeds typical of modern cordless circular saw motors.

What is the difference between kerf thickness and plate thickness, and how do these specs affect performance?

Kerf thickness (0.069 in.) is the width of the cut path made by the carbide tooth tips, while plate thickness (0.043 in.) is the thickness of the steel body of the blade. A full-kerf tooth that is wider than the plate provides lateral clearance so the plate does not bind in the cut. The thinner plate relative to kerf width also reduces the amount of material removed per pass and helps manage heat generation during extended finish cutting sessions.

Why buy a 10-pack instead of individual blades?

The 10-piece bulk masterpack format is designed for contractors and crews running multiple saws or working through high volumes of sheet material on a jobsite. Having 10 identical blades on hand ensures that a worn or damaged blade can be swapped immediately without stopping work, and that cut quality stays consistent across all machines and throughout the duration of a project.
