CMT 293.024.12M Ripping Saw Blade 300 x 30mm T24 10ATB by CMT is a 300mm metric saw blade engineered for fast, efficient ripping of hardwood and softwood in demanding production environments. With a 24-tooth Alternate Top Bevel grind and an aggressive 20 deg. hook angle, this blade drives through solid wood quickly and smoothly, making it an ideal choice for miter saws, radial arm saws, table saws, and squaring machines running metric arbors. Designed around the specifications that industrial woodworkers rely on, it delivers the kind of rapid material removal that keeps production lines moving without sacrificing cut quality.

Key Features

• 24-Tooth Alternate Top Bevel (ATB 10) Grind - the 10 deg. ATB tooth geometry slices wood fibers cleanly on both hardwood and softwood, reducing tear-out during fast ripping operations and producing a smoother surface than flat-top alternatives.
• 20 deg. Hook Angle - an aggressive hook angle pulls material into the cut efficiently, increasing feed rate and cutting speed so production ripping tasks are completed in less time.
• 300mm Diameter with 30mm Bore - sized specifically for metric-arbor machinery, including miter saws, radial arm saws, table saws, and squaring equipment, ensuring a direct fit without adapters.
• COMBI3 Pin Hole Configuration - the COMBI3 pin hole pattern provides precise, repeatable blade positioning on compatible machines, supporting accurate, consistent cuts across production runs.
• Hardmetal (HW) Carbide Teeth - tungsten carbide tooth tips resist dulling under the friction and heat of continuous ripping, extending the interval between sharpenings and reducing downtime.
• 6,400 Maximum RPM Rating - the blade is rated for up to 6,400 RPM, accommodating the high-speed spindles found on professional and industrial saws without risk of exceeding safe operating limits.
• Kerf Thickness of 0.126" with 0.087" Plate - the kerf-to-plate ratio minimizes material waste while maintaining blade stability under load, an important consideration when ripping expensive hardwood stock.

Why This Product

• For shops and production facilities that rip both hardwood and softwood, the 24-tooth ATB 10 geometry handles both materials without requiring a blade change, reducing setup time and keeping workflows efficient.
• The 20 deg. hook angle and 6,400 RPM rating together make this blade well matched to the high-feed, high-speed demands of squaring machines and stationary table saws used in volume woodworking operations.
• The 30mm metric bore with COMBI3 pin hole configuration makes this a direct-fit solution for metric-arbor machines, eliminating the need for bushings or adapters that can introduce runout and affect cut accuracy.
• With hardmetal carbide teeth and a tooth count optimized for ripping rather than crosscutting, this blade prioritizes cutting speed and edge retention - the two factors that matter most when processing large quantities of solid wood or sheet goods like plywood and OSB.

Frequently Asked Questions

What machines is the CMT 293.024.12M compatible with?

This 300mm blade is compatible with miter saws, radial arm saws, table saws, and squaring machines. It requires a 30mm metric arbor bore and the COMBI3 pin hole configuration for proper fitment.

What is the maximum safe operating speed for this blade?

The blade is rated for a maximum of 6,400 RPM. Always confirm that your machine's spindle speed does not exceed this rating before operating.

What does the ATB 10 tooth grind mean for cutting performance?

ATB stands for Alternate Top Bevel. On this blade, the bevel angle is 10 deg. This geometry alternates the bevel direction from tooth to tooth, which shears wood fibers cleanly on both the push and pull side of each tooth. The result is reduced tear-out and a cleaner cut surface when ripping hardwood and softwood compared to a flat-top grind.

Why does the hook angle matter for ripping applications?

The 20 deg. hook angle on this blade is considered aggressive. A higher hook angle causes each tooth to bite into the material more assertively as it rotates, increasing feed rate and cutting speed. This characteristic is particularly valuable in ripping operations where throughput and fast material removal are the priorities.
