The CMT ITK Contractor Saw Blade Finish 6-1/2" x 5/8" T36 ATB is a purpose-built finish circular saw blade engineered for clean, accurate crosscuts in soft and hardwood, plywood, panels, lumber, and OSB sheets. Designed to run on portable and cordless circular saws, this 36-tooth blade delivers the refined cut quality that finish carpentry and trim work demand - without the added bulk of larger saw setups. The Alternate Top Bevel (ATB) tooth geometry and 18 deg. hook angle work together to produce smooth, splinter-reduced results in sheet goods and dimensional lumber alike, making this blade a reliable choice for contractors who need dependable finish-cut performance on the jobsite.

Key Features

• 36-Tooth ATB Geometry at 10 deg. Bevel - the Alternate Top Bevel grind shears wood fibers cleanly at each pass, reducing tearout and producing finish-quality crosscuts in hardwood, softwood, and engineered panels.
• 18 deg. Hook Angle - a moderate positive hook angle balances aggressive feed with controlled cutting behavior, helping maintain smooth results when working with plywood and OSB sheets.
• Thin Kerf Design (0.071" cutting width, 0.047" plate) - a narrow kerf removes less material per pass, reducing load on cordless saw batteries and allowing more cuts per charge - a practical advantage on battery-powered tools.
• 5/8" Bore with Reduction Rings for 1/2" and 10mm - includes reduction rings so the blade fits a wider range of portable and cordless circular saws without needing additional adapters.
• HW (Tungsten Carbide) Tooth Material - carbide-tipped teeth retain sharpness through demanding cutting sessions in hardwood, softwood, and composite panel materials, extending the service life of the blade.
• Maximum 9,500 RPM Rating - the blade is rated for the high rotational speeds common in cordless and corded portable circular saws, keeping it within safe operating parameters for supported machines.
• Optimized for Portable and Cordless Circular Saws - the 6-1/2" diameter and thin-kerf plate are matched to the torque and power characteristics of battery-powered tools, making this a practical choice for mobile finish carpentry work.

Why This Product

• Finish-quality results from a portable setup - the 36-tooth ATB design produces the kind of clean crosscuts typically associated with larger stationary saws, allowing contractors to achieve trim-ready results directly from a cordless circular saw on site.
• Broad material compatibility reduces blade changes - rated for soft and hardwood, plywood, panels, lumber, and OSB sheets, this blade handles the variety of materials common on framing and finish carpentry jobs without requiring a blade swap between tasks.
• Thin kerf extends cordless tool runtime - the 0.047" plate and 0.071" kerf reduce the energy needed per cut, which translates directly to more cuts per battery charge on cordless circular saws - a real efficiency gain on larger finish jobs.
• Versatile bore fit out of the box - the included reduction rings for 1/2" and 10mm bores mean this blade installs directly on a wider range of tool brands and models without sourcing separate adapters.

Frequently Asked Questions

What types of saws is this blade compatible with?

This blade is designed for portable and cordless circular saws. The 6-1/2" diameter and thin-kerf construction are specifically matched to the power and torque characteristics of battery-powered and corded portable circular saws.

What materials can this blade cut?

The ITK Contractor Finish blade is rated for soft and hardwood, panels, dimensional lumber, plywood, and OSB sheets. It is optimized for finishing crosscuts rather than ripping operations.

Does this blade fit saws with bores smaller than 5/8"?

Yes. The blade includes reduction rings for 1/2" and 10mm bores, allowing it to fit a wider range of portable and cordless circular saws without requiring separate adapter hardware.

Why is a thin-kerf blade beneficial for cordless circular saws?

The 0.071" kerf and 0.047" plate thickness mean the blade removes less material per cut and requires less energy from the saw motor. On battery-powered tools, this reduced load can result in more cuts per charge and less strain on the tool during extended finish carpentry sessions.
