CMT 213.048.12 General Purpose Saw Blade by CMT is a 12 in. x 1 in. bore, 48-tooth circular saw blade engineered for professional woodworkers who need reliable rip and crosscut performance in a single blade. Built with an Alternate Top Bevel (ATB) tooth grind and coated with CMT's Orange Shield non-stick PTFE finish, this industrial-grade blade delivers exceptional cut quality in softwood, hardwood, and plywood - making it a go-to workhorse for table saws, miter saws, radial arm saws, and specialty machines alike.

Key Features

• 48-Tooth ATB 20 deg. Grind - the Alternate Top Bevel configuration slices cleanly across and with the grain, producing an exceptional finish on rips and crosscuts without requiring a blade change between operations.
• Orange Shield Non-Stick PTFE Coating - protects the blade body against corrosion, resin buildup, and heat-induced drag, extending cutting life and maintaining consistent blade performance through heavy daily use.
• Thin Kerf Design - 0.126 in. Kerf / 0.100 in. Plate - removes less material per pass, reducing strain on the motor and improving efficiency on radial arm saws, miter saws, and table saws.
• 10 deg. Hook (Cutting) Angle - a positive hook angle provides an aggressive but controlled feed rate, balancing cutting speed with clean surface quality on both soft and hard woods.
• HW (Hardmetal/Carbide) Tooth Material - carbide-tipped teeth maintain their edge longer than standard steel, reducing sharpening frequency and keeping the blade productive under sustained professional use.
• 6,400 RPM Maximum Rating - rated for high-speed operation, making this blade compatible with a wide range of professional stationary and sliding miter saw platforms.
• 25.4mm (1 in.) Bore Diameter - fits standard 1 in. arbors found on most table saws and miter saws, ensuring broad machine compatibility without adapters.
• Industrial General Purpose Classification - designed for professional shop environments where a single versatile blade must perform across multiple wood species and cutting directions throughout the workday.

Why This Product

• One blade for ripping and crosscutting - the 48-tooth ATB grind handles both cut directions with an exceptional finish, reducing the need to swap blades between tasks on the table saw or miter saw.
• Performs across a broad range of wood materials - rated excellent for softwood and hardwood and good for plywood, making it a practical choice for shops working with mixed lumber and sheet goods.
• Thin kerf construction reduces motor load - the 0.126 in. kerf and 0.100 in. plate are engineered to minimize waste and power draw, which is especially valuable on radial arm saws and sliding miter saws where motor capacity is a factor.
• PTFE coating addresses two common blade problems at once - by resisting both resin adhesion and corrosion, the Orange Shield coating helps the blade stay cleaner and cut truer over a longer service life without frequent cleaning or early replacement.

Frequently Asked Questions

What tooth grind does the CMT 213.048.12 use, and why does it matter?

This blade uses an Alternate Top Bevel (ATB) grind at 20 deg., which means adjacent teeth are beveled in alternating directions. This geometry shears wood fibers cleanly on both rip and crosscut passes, producing an exceptional finish without requiring a dedicated ripping or crosscut blade.

Is this blade compatible with my miter saw or table saw?

The CMT 213.048.12 is designed for radial arm saws, miter saws, table saws, and special saws with a standard 1 in. (25.4mm) arbor. It is rated to 6,400 RPM. Always verify your machine's arbor size, blade diameter capacity, and maximum RPM rating before installing any saw blade.

What materials can I cut with this blade?

According to CMT's product data, this blade performs excellently in softwood and hardwood, and provides good performance in plywood. It is classified as a general purpose blade intended to handle a variety of common wood materials in a professional shop setting.

What does the Orange Shield PTFE coating do for blade performance?

The Orange Shield coating is a non-stick PTFE finish applied to the blade body. It resists resin and pitch buildup that can cause friction and blade drag during cutting, and it also protects the plate against corrosion. Both benefits help maintain consistent cutting performance and extend the service life of the blade.
