CMT 290.210.24M General Purpose Saw Blade is an 8-1/4 in. (210mm) circular saw blade engineered for everyday cutting demands across hardwood, softwood, plywood, and OSB. With a 30mm bore diameter and 24 ATB (Alternate Top Bevel) teeth ground to a 10 deg. sharpening angle and a 20 deg. hook angle, this blade delivers clean rip cuts and crosscuts on stationary table saws, miter saws, slide miter saws, radial arm saws, and portable circular saws. Designed specifically for Festool metric-arbor machines, it fills the gap for users who need a capable general-purpose blade without the orange chrome finish.

Key Features

• 24-tooth ATB geometry - the Alternate Top Bevel configuration at 10 deg. sharpening produces cleaner entry and exit cuts in both hardwood and softwood, reducing tearout and improving finished-edge quality.
• 20 deg. hook (cutting) angle - an aggressive hook angle pulls material into the blade efficiently, making ripping and crosscutting faster and requiring less feed force from the operator.
• 8-1/4 in. (210mm) diameter with 30mm bore - sized precisely for Festool and other metric-arbor saws, eliminating the need for adapter bushings and maintaining proper blade registration for accurate cuts.
• Pin hole pattern 2/7/42 - matches Festool machine pin configurations so the blade seats securely and spins true, reducing runout and vibration during operation.
• 0.110 in. kerf thickness with 0.071 in. plate - the thin kerf removes less material per pass, which means less strain on the motor, reduced material waste, and cleaner cuts in sheet goods like plywood and OSB.
• Hardmetal (HW) carbide tips - industrial-grade carbide teeth maintain a sharp cutting edge longer than standard steel, giving the blade extended service life even through demanding production cutting schedules.
• Precision-sharpened teeth - each tooth is individually sharpened to tight tolerances, ensuring consistent cut quality from the first pass to the last throughout the blade's working life.
• Not orange chrome coated - the blade carries no orange chrome finish, making it easy to distinguish from standard CMT blades when organizing a mixed-blade tool inventory.

Why This Product

• Built for Festool metric-arbor machines - the 30mm bore and 2/7/42 pin hole pattern match Festool track saws and plunge saws directly, so there is no guesswork about fit and no need for aftermarket adapters.
• Handles ripping and crosscutting in one blade - the 24-tooth ATB design works across both cut orientations in hardwood, softwood, plywood, and OSB, reducing the need to swap blades when switching between tasks on a job site or in a shop.
• Thin kerf protects portable and cordless tools - at 0.110 in. kerf, this blade draws less power per cut, which is a practical advantage when running Festool or other portable saws on battery or lower-amperage circuits.
• Industrial carbide construction for production use - HW-grade hardmetal tips are suited for repeated daily cutting in demanding shop environments, not just occasional DIY use, making this blade a durable investment for professional woodworkers and contractors.

Frequently Asked Questions

Is this blade compatible with Festool track saws and plunge saws?

Yes. The blade features a 30mm bore diameter and a 2/7/42 pin hole pattern that is designed for Festool machines. It does not carry the orange chrome coating found on standard CMT blades, but it is otherwise built to seat correctly in Festool metric-arbor saws.

What materials can this blade cut?

This general-purpose blade is rated for hardwood, softwood, plywood, and OSB. The 24-tooth ATB geometry makes it suitable for both ripping along the grain and crosscutting across it in these materials.

What is the difference between the kerf thickness and the plate thickness?

The kerf thickness (0.110 in.) is the total width of the cut made by the carbide tooth tips, while the plate thickness (0.071 in.) is the thickness of the steel body of the blade itself. The difference between the two gives the tooth its set, which keeps the plate from binding in the cut.

Can this blade be used on a miter saw or radial arm saw, or only on track saws?

This blade is compatible with a range of machines including radial arm saws, stationary table saws, portable circular saws, miter saws, and slide miter saws - in addition to Festool metric-arbor track saws. The 30mm bore is required, so confirm your machine's arbor size before installing.
