Product Description
The CMT ITK Contractor Saw Blade General Purpose 12" x 1" T40 ATB is a professional-grade circular saw blade engineered for accurate rip cuts and crosscuts in soft and hardwood on portable benchtop and stationary table saws. Built with a 40-tooth Alternate Top Bevel (ATB) grind and hardwood-grade carbide tips, this 12-inch blade delivers consistent, clean results across general construction and woodworking applications where both ripping and crosscutting performance are required in a single blade.
Key Features
- 40-Tooth ATB Tooth Configuration - the Alternate Top Bevel geometry produces shear-cutting action across the grain, reducing tear-out and leaving cleaner edges on both rip cuts and crosscuts in soft and hardwood.
- 10 deg. ATB Sharpening Angle - a moderate bevel angle balances aggressiveness and finish quality, making this blade a practical general-purpose choice for mixed woodworking tasks without swapping blades.
- 15 deg. Cutting (Hook) Angle - a positive hook angle promotes efficient feed rates on table saws and portable benchtop saws, reducing operator effort and improving cut throughput.
- HW (Hardwood-Grade Carbide) Tooth Material - harder, denser carbide tips maintain edge retention longer when cutting dense hardwoods and construction lumber, extending the interval between resharpenings.
- 0.102" Kerf Thickness with 0.071" Plate - the blade is engineered with a controlled kerf-to-plate ratio that provides lateral stability during cutting, reducing deflection and keeping cuts on-line even in longer rip cuts.
- 1" (25.4 mm) Bore Diameter - fits the standard arbor size found on most portable benchtop and stationary table saws, making this blade a direct-fit replacement for a wide range of machines without adapters.
- 6,400 RPM Maximum Speed Rating - rated for high-speed operation, supporting use on full-power table saws and portable saws at their rated speeds without compromising safety margins.
Why This Product
- One blade for ripping and crosscutting - the 40-tooth ATB design handles both rip cuts along the grain and crosscuts across it in soft and hardwood, reducing the need to keep multiple dedicated blades on hand for general contractor and woodworking tasks.
- Purpose-matched for contractor saws and portable table saws - the 12-inch diameter and 1-inch bore are spec-matched directly for the portable benchtop and table saw class, ensuring proper fit and balanced performance without shimming or adapters.
- High-speed capable for demanding jobsite use - the 6,400 RPM rating supports operation at the full rated speed of contractor-class table saws, where lower-rated blades may introduce unnecessary risk or performance limits.
- Hardwood-grade carbide for longer service life - HW carbide tooth material holds up in dense hardwoods and mixed construction lumber, making this blade a cost-effective choice for contractors who cut a variety of wood species across a single project.

Frequently Asked Questions
What is the maximum RPM for this blade, and is it safe to use on a full-power contractor table saw?
This blade is rated for a maximum of 6,400 RPM, which supports use at the full rated speed of most contractor-class and portable benchtop table saws. Always verify your saw's rated speed does not exceed 6,400 RPM before mounting the blade.
Can this blade cut both rips and crosscuts, or is it optimized for just one direction?
This is a general purpose blade specifically designed for both accurate rip cuts and crosscuts. The 40-tooth ATB (Alternate Top Bevel) geometry and 15 deg. cutting angle handle both cut directions in soft and hardwood without requiring a blade change.
What bore size does this blade use, and will it fit my saw without an adapter?
The bore diameter is 25.4 mm, which is equivalent to a 1-inch arbor - the standard arbor size for most portable benchtop and stationary table saws in the contractor class. No adapter should be needed for compatible machines with a 1-inch arbor.
What does the ATB tooth grind mean for cut quality on hardwood?
ATB stands for Alternate Top Bevel, where each tooth is alternately angled to the left and right. This geometry creates a shearing action across wood fibers rather than chopping through them, which reduces tear-out and splintering - particularly useful when crosscutting hardwood where a clean edge matters. The HW (hardwood-grade carbide) tooth material further supports edge retention when working with denser species.
