The CMT ITK-Plus Fast Framing Blade - 6-1/2" x 5/8" - 18-Tooth ATB+Shear is a professional-grade circular saw blade engineered for rapid, accurate cuts in wood framing, sheathing, and structural panel applications. Built with an Alternate Top Bevel plus Shear (ATB+S) tooth geometry and a 20 deg. hook angle, this 6-1/2" blade is optimized for use with cordless circular saws and portable table saws, delivering the aggressive feed rate and clean finish that framing crews and contractors demand on the job site.

Key Features

• 18-Tooth ATB+Shear Grind (10 deg. ATB+S) - the Alternate Top Bevel with Shear tooth geometry slices through wood fibers efficiently, producing faster material removal with reduced tear-out on framing lumber, plywood, OSB, and hardboard.
• 20 deg. Hook (Cutting) Angle - an aggressive positive hook angle drives teeth into the workpiece quickly, reducing cutting resistance and enabling faster feed rates that keep framing work moving.
• 6-1/2" Diameter with 5/8" Bore - the compact blade diameter pairs with a standard 5/8" arbor bore, making it directly compatible with the most widely used cordless circular saws and portable table saws in the field.
• Kerf Thickness of 0.069" over a 0.036" Plate - a thin kerf design removes less material per cut, reducing the load on the motor and helping extend battery life on cordless tools during sustained framing operations.
• Maximum 9,500 RPM Rating - rated for high-speed operation to match the output of modern cordless and corded circular saws, ensuring safe performance at full tool speed.
• Hardmetal (HW) Carbide Teeth - industrial carbide tooth material maintains a sharp cutting edge longer than standard steel, reducing the frequency of blade changes during extended framing sessions.
• ITK-Plus Construction - the full-body laser-cut steel plate is manufactured to tight tolerances, ensuring stable, vibration-free cutting and consistent kerf width throughout the life of the blade.

Why This Product

• Purpose-built for fast framing - the 18-tooth count and 20 deg. hook angle are specifically configured for the high-volume, fast-paced cutting demands of structural framing work, where speed matters more than a furniture-grade finish.
• Thin-kerf advantage on cordless tools - the 0.069" kerf paired with the 0.036" plate means the blade draws less power per cut, a direct benefit when running on battery-powered circular saws where runtime and torque are limited.
• Versatile across common jobsite sheet goods - approved for wood, plywood, OSB, and hardboard, so one blade handles the full range of materials a framing crew encounters without frequent changes.
• Compact 6-1/2" size for portability - the 6-1/2" diameter is the standard size for lightweight cordless circular saws, giving tradespeople a blade designed to work with the tools they already carry rather than requiring a larger, heavier setup.

Frequently Asked Questions

What machines is this 6-1/2" 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 tool accepts a 6-1/2" blade with a 5/8" arbor before mounting.

What does ATB+Shear tooth geometry mean for my cuts?

ATB+Shear - Alternate Top Bevel plus Shear - combines a beveled top edge on alternating teeth with a shear angle that slices wood fibers cleanly rather than scraping them. On this blade, that is expressed as a 10 deg. ATB+S grind, which balances fast material removal with a cleaner exit surface compared to a standard flat-top grind.

Is this blade appropriate for use with battery-powered circular saws?

Yes. The 6-1/2" diameter and thin kerf (0.069" kerf over a 0.036" plate) are both well suited for cordless circular saws. The thin-kerf design reduces the cutting load on the motor, which helps conserve battery charge during extended framing work.

Can this blade cut both solid lumber and sheet goods like plywood and OSB?

Yes. The recommended materials include wood, plywood, OSB, and hardboard, making this blade a practical single-blade option for the variety of materials typically encountered during framing and rough construction work.
