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 crosscuts in soft and hardwood, plywood, OSB sheets, and panel lumber. Sold as a 10-piece bulk masterpack, this blade is purpose-built for portable and cordless circular saws, making it an efficient choice for contractors who demand consistent finish-quality results on the jobsite. The 40-tooth Alternate Top Bevel (ATB) grind geometry and 12 deg. cutting angle work together to minimize tearout and produce smooth, accurate cuts through a wide range of wood-based sheet materials.

Key Features

• 40-Tooth ATB Grind (10 deg. sharpening) - the Alternate Top Bevel tooth geometry slices cleanly across wood fibers, reducing splintering and delivering finish-quality crosscuts in hardwood, softwood, and engineered panels like plywood and OSB.
• 12 deg. Cutting Angle - this hook angle is optimized for finish crosscutting, providing controlled feed and smooth surface quality rather than aggressive rip behavior.
• 0.071" Kerf Thickness - a thin kerf reduces material waste and demands less power from cordless tools, helping battery-powered saws cut longer between charges.
• 0.047" Plate Thickness - a slender plate minimizes side friction and heat buildup, contributing to stable, accurate cutting performance over extended use.
• 5/8" Bore with Reduction Rings for 1/2" and 10mm Bores - the included reduction rings broaden compatibility across a wider range of portable and cordless circular saw models without needing separate arbor adapters.
• 8,300 RPM Maximum Rating - rated for high-speed operation to match the demands of professional-grade cordless and corded circular saws on demanding finish applications.
• Hard Metal (HW) Carbide Tips - tungsten carbide tooth material maintains a sharp edge longer than standard steel, reducing resharpening frequency and extending overall blade service life.
• 10-Piece Bulk Masterpack - stocking a full pack ensures crews always have a fresh blade on hand, reducing downtime on multi-day or multi-crew finish carpentry projects.

Why This Product

• Contractors cutting finish trim, cabinetry, or panel goods need a blade that minimizes tearout - the 40-tooth ATB design with 10 deg. sharpening is specifically configured for that clean crosscut result in soft and hardwood, plywood, and OSB.
• The thin 0.071" kerf is a practical advantage for cordless circular saw users, since less material removal means less load on the motor and longer runtime per battery charge on the jobsite.
• Reduction rings for 1/2" and 10mm bores are physically included in the pack, so a single blade SKU works across multiple saw platforms without sourcing additional hardware.
• Buying a 10-piece masterpack at once lowers the per-blade cost and keeps supply consistent across a crew, eliminating last-minute blade shortages during finish-phase work on hardwood panels, lumber, and sheet goods.

Frequently Asked Questions

What machines are these blades compatible with?

These blades are designed for use with portable and cordless circular saws. The 5/8" bore with included reduction rings for 1/2" and 10mm bores broadens compatibility across a variety of circular saw models.

What materials can these blades cut?

The CMT ITK Contractor Finish blades are suited for cutting soft and hardwood, panel lumber, plywood, and OSB sheets. They are optimized specifically for finishing crosscuts in these wood-based materials.

Why is the thin kerf beneficial for cordless circular saws?

The 0.071" kerf thickness removes less material per cut, which reduces the power demand on the saw motor. For cordless tools, this translates to less battery drain and longer cutting sessions between charges - a practical advantage on jobsites without easy access to power.

Are all 10 blades identical in the masterpack?

Yes. The 10-piece bulk masterpack contains 10 identical CMT ITK Contractor Finish blades, each with a 7-1/4" diameter, 40-tooth ATB grind, 12 deg. cutting angle, 0.071" kerf, and 5/8" bore with reduction rings included.
