The CMT Metal and Stainless Steel Saw Blade - 7-1/4" x 5/8" T48 FWF is a 48-tooth carbide-tipped circular saw blade engineered for cutting metal, stainless steel, channels, studs, angles, plates, pipes, and flat bars with a corded or cordless circular saw. Featuring CMT's ITK Xtreme tooth design and a Flat with Alternate Chamfer (FWF) grind at 0 deg. hook angle, this blade delivers clean, dry cuts through ferrous materials without the need for coolant. Designed for demanding metal fabrication and construction applications, it is fully compatible with standard 7-1/4" circular saws and cordless circular saws up to 6,000 RPM.

Key Features

• ITK Xtreme Tooth Technology - CMT's advanced carbide tooth engineering maintains cutting precision and edge integrity through repetitive cuts in hard metal and stainless steel, reducing heat buildup and extending blade life.
• Flat with Alternate Chamfer (FWF) Tooth Grind at 8 deg. - this specialized tooth geometry shears metal cleanly and leaves a burr-free edge, making it suitable for cutting stainless steel grades 302, 303, and 304 without coolant.
• 0 deg. Hook Angle - a neutral cutting angle controls feed rate through dense metal stock, reducing blade grab and improving operator safety during freehand circular saw cuts.
• 48 Carbide Teeth (HW Material) - the high tooth count produces smoother, finer cuts through channels, studs, angles, flat bars, pipes, and plates, minimizing secondary finishing work.
• 0.080" Kerf and 0.065" Plate Thickness - the optimized kerf-to-plate ratio removes material efficiently while keeping the blade body rigid and stable throughout the cut.
• 5/8" Bore with Knock-Out Pin Hole - the standard 5/8" arbor bore fits the most common 7-1/4" circular saws, and the knock-out pin hole provides additional compatibility for saws requiring a pin-drive arbor configuration.
• 6,000 Maximum RPM Rating - rated for the higher spindle speeds typical of corded circular saws, ensuring safe operation at full tool capacity without exceeding the blade's design limits.

Why This Product

• Cutting stainless steel on-site often requires either an angle grinder or a blade that can handle hard ferrous alloys without a coolant system - this blade handles stainless steel grades 302, 303, and 304 dry, with a standard 7-1/4" circular saw.
• The ITK Xtreme carbide tooth construction is specifically rated for metal and stainless steel cutting, not just general purpose use, making it a purpose-built choice for metal studs, structural angles, pipes, and flat bar stock.
• With a 0 deg. hook angle and FWF tooth geometry, the blade controls its own feed rate through dense material, reducing the risk of blade climb or grab that can occur with wood-optimized blades misused on metal.
• The knock-out pin hole and standard 5/8" bore make this blade a drop-in fit for a wide range of 7-1/4" corded and cordless circular saws, with no adapters required for most common platforms.

Frequently Asked Questions

What stainless steel grades is this blade rated for?

This blade is engineered for stainless steel grades 302, 303, and 304. Performance is not guaranteed on harder grades such as 316.

Does this blade require coolant or cutting fluid when cutting stainless steel?

No. The FWF 8 tooth geometry and ITK Xtreme carbide tooth design allow dry cutting of metal and stainless steel without coolant, making it practical for jobsite use with a standard circular saw.

What circular saws is this blade compatible with?

This blade is designed for use with 7-1/4" corded circular saws and cordless circular saws. It features a standard 5/8" bore diameter and a knock-out pin hole for compatibility with a wide range of saw arbor configurations. The blade is rated for a maximum of 6,000 RPM.

What is the difference between the kerf thickness and the plate thickness on this blade?

The kerf thickness (0.080") is the width of material removed by the teeth during the cut. The plate thickness (0.065") is the thickness of the blade body itself. The difference between these two measurements - known as the set - provides clearance so the blade body does not bind in the kerf during cutting.

Note: Performance is not guaranteed on harder stainless steel grades such as 316.
