The CMT ITK-Plus Finish Blade 7-1/4" x 5/8" T40 ATB+Shear is a precision-ground carbide circular saw blade engineered for smooth, splinter-free finish cuts in wood, plywood, OSB, and hardboard. With 40 teeth ground in an Alternate Top Bevel plus Shear configuration, this 7-1/4 in. blade is optimized for use on cordless circular saws and portable table saws, delivering professional-quality finish results in demanding jobsite conditions.

Key Features

• 40-Tooth ATB+Shear Grind (10 deg. ATB + Shear) - the alternate top bevel combined with a shear angle slices through wood fibers cleanly, reducing tearout and producing fine finish-quality cuts in plywood, OSB, and hardboard.
• 18 deg. Hook Angle - an aggressive positive hook angle helps the blade feed efficiently through material, reducing effort and improving cut quality on portable saws.
• Tungsten Carbide (HW) Tooth Material - hard-metal carbide tips maintain a sharp cutting edge through extended use, meaning fewer blade changes and lower long-term tooling costs.
• Kerf Thickness of 0.069 in. - a thin kerf removes less material per pass, which is especially valuable when running cordless circular saws where motor efficiency and battery runtime matter.
• Plate Thickness of 0.043 in. - a slender plate minimizes vibration and flexing during cuts, contributing to straighter, more consistent finish results.
• 8,300 RPM Rating - a high maximum speed rating gives this blade the headroom to run safely and effectively on fast-spinning cordless and portable table saw spindles.
• 5/8 in. Bore Diameter - standard 5/8 in. arbor compatibility fits the vast majority of 7-1/4 in. cordless circular saws and portable table saws without requiring adapters.

Why This Product

• Purpose-built for finish-quality results on wood, plywood, OSB, and hardboard - this is not a general-purpose combination blade but a dedicated finish blade designed to deliver clean edges where appearance matters.
• The ATB+Shear tooth geometry makes it a strong choice for cutting sheet goods like plywood and OSB where face-side tearout is a concern on cordless saws.
• At 40 teeth with a thin 0.069 in. kerf, this blade strikes a practical balance between cut smoothness and the reduced drag that cordless circular saw motors and batteries benefit from during extended use.
• The 8,300 RPM maximum speed rating means this blade is sized and rated to operate confidently on modern high-speed cordless circular saws without approaching unsafe operating limits.

Frequently Asked Questions

What machines is this blade compatible with?

This blade is suitable for cordless circular saws and portable table saws. Blade diameter compatibility is contingent on machine type, so confirm your saw accepts a 7-1/4 in. blade with a 5/8 in. arbor before installing.

What does the ATB+Shear tooth grind mean for my cuts?

ATB+Shear stands for Alternate Top Bevel plus Shear, which in this blade is specified as 10 ATB+S. The combination of the alternating bevel and the added shear angle allows the teeth to slice rather than chop through wood fibers, which reduces tearout and produces cleaner edges - especially on plywood and OSB face veneers.

Is this blade suitable for cutting melamine or MDF?

According to the product data, the recommended materials for this blade are wood, plywood, OSB, and hardboard. Melamine and MDF are not listed as approved materials for this specific blade.

Why does the kerf thickness matter for cordless saw use?

This blade features a 0.069 in. kerf, which is considered a thin-kerf design. A thinner kerf removes less material with each pass, which reduces the load on the saw motor and draws less power from the battery. This makes thin-kerf blades particularly well-suited for cordless circular saws where battery runtime and motor efficiency are priorities.
