CMT Xtreme Demolition Saw Blade 6-1/2" 24T by CMT is a professional-grade circular saw blade engineered specifically for demolition cutting in demanding job site conditions. Built for metric-arbor cordless circular saws, corded circular saws, and track saws, this 6-1/2" blade tears through demolition materials, wood with embedded nails, pressure-treated lumber, OSB, laminated beams, and plywood without hesitation. Whether you are ripping structural lumber on a remodel or making crosscuts through reclaimed material on a demo site, this blade delivers consistent results through a 20mm bore that fits Festool and other metric-arbor tool platforms.

Key Features

• Alternate Top Bevel (ATB) 5 deg. tooth grind - the angled cutting edge slices cleanly through wood fibers and mixed demolition debris, reducing tear-out and helping the blade shed material efficiently with each pass.
• 24-tooth configuration - provides an aggressive cutting balance well suited for ripping and crosscutting demolition material, keeping the blade moving quickly without bogging down in thick or nail-embedded stock.
• 5 deg. hook angle - a positive hook pulls the blade into the cut with controlled aggression, helping maintain feed rate through dense or contaminated demolition lumber.
• 0.090" kerf thickness - a robust kerf width removes material decisively while the 0.049" plate provides the structural rigidity needed to resist flex under impact loads common in demolition work.
• Hardmetal (HW) carbide tips - tungsten carbide tooth material withstands the punishing abuse of cutting nails, screws, and mixed debris without premature dulling, extending the usable life of the blade on tough demolition applications.
• 20mm metric bore with 2/6/32 pin hole - designed to fit metric-arbor cordless and track saw platforms directly, eliminating the need for adapter rings and ensuring secure, accurate blade seating.
• 9,500 maximum RPM rating - compatible with the high-speed output of modern cordless circular saws and track saws, so the blade performs safely at full tool speed without exceeding its structural limits.
• Orange chrome coating - the chromium surface treatment guards against corrosion and surface wear, keeping the blade protected in wet, muddy, or chemically treated demolition environments and extending overall blade service life.

Why This Product

• Designed from the ground up for demolition cutting - this blade handles wood with embedded nails, pressure-treated lumber, OSB, and laminated beams rather than being a general-purpose blade pressed into a demanding role.
• The 20mm metric bore and 2/6/32 pin hole configuration make it a direct fit for metric-arbor track saws and cordless circular saws, removing the guesswork of adapting an inch-bore blade to a metric tool platform.
• The hardmetal (HW) carbide tooth material paired with an ATB 5 deg. grind gives the blade the edge retention needed to keep cutting through contaminated material rather than dulling after the first few nail strikes.
• At 6-1/2" diameter with a 9,500 RPM rating, this blade is sized and rated for the compact, high-speed cordless saws commonly used on demo sites where maneuverability and battery efficiency matter.

Frequently Asked Questions

What saws is this blade compatible with?

This blade is compatible with cordless circular saws, corded circular saws, and track saws that accept a 20mm metric bore with a 2/6/32 pin hole configuration. It is well suited for Festool and other metric-arbor tool platforms that operate at or below 9,500 RPM.

Can this blade cut through nails and screws embedded in demolition lumber?

Yes. The blade is specifically engineered for demolition material including wood with embedded nails. The hardmetal (HW) carbide tooth tips provide the wear resistance needed to cut through metal fasteners and mixed debris without immediate dulling.

What does the ATB 5 deg. tooth grind mean for cutting performance?

ATB stands for Alternate Top Bevel, meaning consecutive teeth are ground at opposing 5 deg. angles. This geometry creates a slicing action across wood fibers that reduces tear-out and helps the blade cut cleanly even through mixed demolition material and pressure-treated lumber.

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

The kerf thickness of 0.090" is the total width of the cut the blade makes through the material, determined by the width of the carbide teeth. The plate thickness of 0.049" is the thinner steel body of the blade itself. The difference between these two measurements creates clearance so the plate does not bind in the cut during demolition work.
