The CMT ITK Contractor Saw Blade Finish 7-1/4" x 5/8" T40 ATB is a professional-grade circular saw blade engineered for clean finishing cuts in wood, plywood, and panel materials. Designed for use with portable and cordless circular saws, this 40-tooth blade features an Alternate Top Bevel (ATB) tooth grind at 10 deg. with a 12 deg. hook angle, delivering the precise, splinter-free crosscuts that finishing and trim work demand. Whether you are breaking down OSB sheets on the job site or making finish-quality cuts in softwood and hardwood lumber, this blade is built to meet the demands of contractor-grade applications.

Key Features

• 40-Tooth ATB Grind at 10 deg. - the Alternate Top Bevel configuration slices wood fibers cleanly on each pass, reducing tear-out and producing smooth edges ideal for finish crosscuts in softwood, hardwood, plywood, and panels.
• 12 deg. Hook Angle - a positive hook angle that helps the blade feed through material efficiently, reducing user effort and improving cut control on portable and cordless circular saws.
• Thin Kerf Design (0.071" kerf / 0.047" plate) - the narrow kerf removes less material per cut, reducing load on the motor and extending battery run time on cordless saws - a critical advantage on job sites where power is limited.
• HW (Tungsten Carbide) Tooth Material - hard carbide tips maintain a sharp cutting edge longer than standard steel teeth, reducing the frequency of blade changes and lowering cost per cut over time.
• 5/8" Bore with Reduction Rings for 1/2" and 10mm - included reduction rings allow this blade to fit a wider range of circular saws without purchasing additional adapters, making it versatile across tools on the job site.
• 8,300 RPM Rating - a high maximum RPM rating ensures safe, controlled performance across the full speed range of most portable and cordless circular saws.
• Optimized for Portable and Cordless Circular Saws - the blade geometry and thin-plate design are specifically tuned for handheld saw applications, where balance, vibration control, and low drag matter most.

Why This Product

• Built for finish-quality crosscuts on soft and hardwood - the 40-tooth ATB geometry at 10 deg. is purpose-matched to finishing work in lumber, panels, plywood, and OSB sheets, giving contractors a dedicated blade for trim and finish cuts rather than a general-purpose compromise.
• Thin kerf extends cordless tool battery life - at 0.071" kerf and 0.047" plate thickness, this blade demands less energy per cut, which translates directly to more cuts per battery charge - a practical benefit for cordless circular saw users working away from power sources.
• Multi-bore flexibility right out of the box - the included reduction rings for 1/2" and 10mm bores mean the blade installs on a broader range of saws without sourcing separate adapters, saving time and added expense.
• High RPM rating matches demanding job site tools - rated to 8,300 RPM, this blade operates safely at the top end of portable circular saw speeds, giving professionals confidence that the blade is rated for their equipment.

Frequently Asked Questions

What types of materials can this blade cut?

This blade is designed to cut soft and hardwood, panel lumber, plywood, and OSB sheets. It is optimized for finishing crosscuts rather than general ripping applications.

What saws is this blade compatible with?

This blade is designed for use with portable and cordless circular saws. Its 7-1/4" diameter, thin-kerf geometry, and 8,300 RPM rating make it well suited for handheld circular saw applications on job sites.

Does this blade fit saws with smaller bore sizes?

Yes. The blade includes reduction rings for 1/2" and 10mm bores, so it can be used on circular saws with those bore sizes in addition to the standard 5/8" bore size.

What is the maximum safe operating speed for this blade?

This blade is rated for a maximum of 8,300 RPM. Always confirm that your saw's operating speed does not exceed this rating before use.
