CMT Heavy-Duty General Purpose Saw Blade - 300 x 30mm, 48-Tooth ATB is a professional-grade circular saw blade built for demanding ripping and crosscutting applications across a wide range of wood-based materials. Engineered by CMT with a 48-tooth Alternate Top Bevel grind and a 30mm bore diameter, this blade delivers clean, consistent cuts in hardwood, softwood, plywood, veneered plywood, melamine, and chipboard - making it a versatile solution for both shop and job-site environments. Whether mounted on a stationary table saw, portable table saw, miter saw, or slide miter saw, this 300mm blade is purpose-built for heavy-duty general purpose work where reliability and cut quality are non-negotiable.

Key Features

• 48-Tooth ATB 10 deg. Grind - the Alternate Top Bevel tooth geometry at 10 deg. produces clean entry and exit cuts in both ripping and crosscutting applications, reducing tear-out on veneered panels and melamine surfaces.
• 300mm Diameter with 30mm Bore - sized for metric-arbor machines including stationary and portable table saws, miter saws, and slide miter saws, ensuring a direct, secure fit without adapters.
• 5 deg. Hook Angle - a positive 5 deg. cutting angle balances aggressive feed with controlled material removal, improving performance across both soft and hard wood species.
• COMBI3 Pin Hole Configuration - compatible with a broad range of European-standard machine spindles, providing accurate blade registration and reducing blade wobble for stable, repeatable cuts.
• 0.126 in. Kerf / 0.087 in. Plate Thickness - the thin kerf and plate dimensions reduce material waste and demand less power from the machine, making it well-suited for both high-powered stationary saws and portable table saws.
• HW (Hardwood/Carbide) Tooth Material - tungsten carbide tips maintain a sharp cutting edge longer under the stress of heavy-duty general purpose cutting, reducing resharpening frequency and extending blade service life.
• Rated to 6,400 RPM - the high maximum RPM rating provides compatibility with a wide range of machine speeds, supporting efficient cutting on fast-spinning table saws and sliding miter saws.

Why This Product

• A single blade rated for ripping and crosscutting on hardwood, softwood, plywood, veneered plywood, melamine, and chipboard eliminates the need to swap blades between tasks on mixed-material projects.
• The 30mm bore and COMBI3 pin hole configuration make this blade a direct fit for metric-arbor table saws, miter saws, and slide miter saws - no reduction rings or workarounds required.
• With a 6,400 RPM maximum rating and a thin 0.126 in. kerf, this blade runs efficiently on both stationary shop equipment and portable table saws, giving consistent results across different machine setups.
• The 48-tooth ATB grind handles the full range of heavy-duty general purpose cuts - from rough ripping solid lumber to finish crosscutting melamine-faced chipboard - without requiring a specialty blade for each material.

Frequently Asked Questions

What machines is this 300mm saw blade compatible with?

This blade is designed for use on miter saws, slide miter saws, stationary table saws, and portable table saws equipped with a 30mm metric arbor and COMBI3 pin hole configuration.

What is the maximum RPM for this blade?

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

What tooth grind type does this blade use, and why does it matter?

This blade uses an Alternate Top Bevel (ATB) grind at 10 deg. The ATB geometry alternates the bevel direction on successive teeth, which produces clean cuts on both the top and bottom face of the material - particularly useful when cutting veneered plywood, melamine, and chipboard where surface tear-out is a concern.

Can this blade cut both with the grain (ripping) and across the grain (crosscutting)?

Yes. This blade is specifically designed as a heavy-duty general purpose blade rated for both ripping and crosscutting on hardwood, softwood, plywood, veneered plywood, melamine, and chipboard.
