CMT 226.048.08M Metal and Steel Dry Cut Saw Blade is an industrial-grade circular saw blade engineered for clean, burr-free dry cutting of metal and steel without coolant. With an 8-1/4 in. (210mm) diameter, 48 flat with alternate chamfer (FWF) teeth, and a 30mm bore, this blade is built for demanding metal fabrication work on circular saws, miter saws, and chop miter saws. Designed to cut channel, studs, angles, plates, pipes, rods, and similar steel profiles, it delivers precision crosscuts through medium and thick metal stock at up to 4,500 RPM. The hardmetal-tipped tooth construction and zero deg. hook angle make it an effective solution for contractors and fabricators who need accurate, controlled cuts through ferrous materials on a regular basis.

Key Features

• Flat with Alternate Chamfer (FWF) Tooth Grind at 8 deg. - this engineered tooth geometry produces clean, burr-free cuts in metal and steel without requiring coolant, reducing finishing time and cleanup on the job site.
• 48 Hardmetal (HW) Tips - the high tooth count paired with industrial-grade carbide tips delivers smooth, controlled cuts through channel, studs, angles, plates, pipes, and rods with minimal material tear-out.
• 0 deg. Hook Angle - a neutral cutting angle prevents the blade from aggressively grabbing metal workpieces, giving the operator better control and reducing the risk of kickback when cutting steel profiles.
• 0.087 in. Kerf Thickness with 0.071 in. Plate - the thin kerf-to-plate ratio means less material is removed per cut, reducing heat generation during dry cutting and extending blade life in repetitive production environments.
• 30mm Bore with Reducing Rings (25.4mm and 15.88mm) - the multi-bore compatibility means this blade fits a wider range of circular saw and miter saw arbors without requiring separate adapters, increasing machine versatility.
• Pin Hole Configuration 2/7/42 - compatible with machines that require pin-drive blade mounting, such as specific miter and chop miter saw models, ensuring secure blade seating during high-load metal cutting passes.
• Maximum 4,500 RPM Rating - the blade is rated for the high-speed operation typical of dry-cut metal saws and chop miter saws, providing confidence that the blade is matched to the demands of the machine.

Why This Product

• No coolant required for metal cutting - this blade is specifically designed for dry cutting of steel and metal profiles, eliminating the mess, cost, and setup time associated with wet-cut abrasive systems while still delivering burr-free results.
• Broad material compatibility for structural fabrication work - the 48-tooth FWF grind handles channel, studs, angles, flat plates, pipes, tubes, and rods in a single blade, reducing the need to swap blades when working with varied steel stock.
• Fits multiple machines with one blade - the 30mm bore with included 25.4mm and 15.88mm reducing rings means this blade adapts to different circular saw, miter saw, and chop miter saw arbor sizes without purchasing additional hardware.
• Industrial dry-cutter design for Festool-compatible machines - built specifically for use with Festool machines among other circular saws, this blade suits contractors and fabricators who rely on precision guide-rail cutting systems for accurate metal work.

Frequently Asked Questions

Does this blade require coolant or cutting fluid when cutting metal?

No. This blade is specifically designed as a dry-cut saw blade for metal and steel. The FWF tooth geometry allows it to cut channel, studs, angles, plates, pipes, and rods cleanly without coolant or cutting fluid, making it well suited for job-site use where wet-cut setups are impractical.

What bore sizes does this blade fit?

The blade has a primary bore diameter of 30mm and includes reducing rings for 25.4mm and 15.88mm arbors, allowing it to fit a range of circular saws, miter saws, and chop miter saws with different arbor specifications.

What is the maximum safe operating speed for this blade?

The maximum rated speed is 4,500 RPM. Always verify that your saw's no-load RPM does not exceed this rating before mounting and operating the blade.

What does the FWF tooth grind mean, and why does it matter for metal cutting?

FWF stands for Flat with Alternate Chamfer, ground at 8 deg. This tooth geometry is specifically engineered for cutting metal and steel, producing smooth, burr-free cuts that require minimal edge cleanup. Combined with the 0 deg. hook angle, it provides controlled cutting action that reduces grabbing and helps manage heat buildup during dry ferrous metal cutting.
