The CMT ITK Xtreme Wood and Metal Saw Blade is a 7-1/4 in. x 5/8 in. 36-tooth carbide blade engineered for contractors and tradespeople who need a single cutting tool that handles both wood and metal in demanding jobsite conditions. Designed for use in cordless circular saws, standard circular saws, and miter saws, this blade tackles demolition debris, pressure-treated lumber, OSB, metal channels, studs, angles, rods, and pipes without swapping blades. The Modified Alternate Top Bevel (MATB) tooth geometry combined with Tri-Metal Silver-Copper-Silver brazing makes it a reliable choice for mixed-material cutting on framing, renovation, and demolition sites.

Key Features

• Modified Alternate Top Bevel (MATB) Tooth Geometry - a hybrid grind designed to cut both wood-based sheet goods and metal structural components cleanly, eliminating the need to switch between dedicated blades on mixed-material jobs.
• Tri-Metal Silver-Copper-Silver Brazing - the special silver-copper-silver brazing method bonds carbide teeth to the blade body with exceptional holding strength, allowing each tooth to withstand high stress and impact when cutting harder woods, composite material, and metal profiles.
• Special Straightening Processes for Blade Body Flatness - blade body flatness is achieved through dedicated straightening processes that guarantee exceptionally reduced tolerances, while factory balancing on every blade ensures maximum stability and reduced vibration during cuts.
• Knock-Out Pin Hole Bore (5/8 in.) - the 15.88 mm bore with knock-out pin hole arbor design fits standard 5/8 in. arbors found on most cordless and corded circular saws, making this blade broadly compatible across tool brands and platforms.
• 5 deg. Cutting Angle - the 5 deg. hook angle is optimized for controlled feed rate through dense or abrasive materials like pressure-treated lumber and metal framing, reducing blade grab and maintaining cut quality.
• 0.067 in. Kerf / 0.049 in. Plate - a thin 0.049 in. plate with a 0.067 in. kerf keeps material removal efficient and reduces the load on cordless tool batteries, extending runtime per charge.
• 8,300 Maximum RPM Rating - rated to 8,300 RPM to match the higher no-load speeds common on compact cordless circular saws, ensuring safe operation across the full speed range of compatible tools.

Why This Product

• One blade handles demolition materials, pressure-treated lumber, OSB, metal channels, studs, angles, rods, and pipes - reducing the number of blades a crew needs to carry and swap on a renovation or framing site.
• The 8,300 RPM maximum rating makes this blade genuinely safe and effective in high-speed cordless circular saws, where many standard blades fall short of the tool's operating speed range.
• Tri-Metal Silver-Copper-Silver brazing provides superior tooth retention compared to standard single-material brazing, giving the blade extra durability when teeth strike embedded fasteners, rebar, or knots during demolition cuts.
• Factory balancing on every blade combined with tight plate tolerances from special straightening processes means smoother cuts and less vibration fatigue for the operator over a full work day.

Frequently Asked Questions

What saws is this blade compatible with?

This blade is designed for use in cordless circular saws, standard circular saws, and miter saws. The 5/8 in. (15.88 mm) bore with knock-out pin hole fits the standard arbor size found on most tools in these categories.

Can this blade cut metal and wood on the same job without switching blades?

Yes. The ITK Xtreme series is specifically designed for mixed-material cutting. The MATB tooth geometry and Tri-Metal Silver-Copper-Silver brazing allow the blade to cut demolition materials, pressure-treated lumber, OSB, metal channels, studs, angles, rods, and pipes in a single blade - making it well suited for renovation and demolition work where both wood and metal components are present.

What does the MATB tooth grind mean and why does it matter?

MATB stands for Modified Alternate Top Bevel. This hybrid tooth geometry is engineered to perform effectively on both wood-based materials and metal profiles. The alternating bevel angles on adjacent teeth share the cutting load and reduce heat buildup, which is especially important when cutting harder or abrasive materials like pressure-treated lumber and metal studs.

What is the maximum safe operating speed for this blade?

This blade is rated to a maximum of 8,300 RPM. Always verify that your saw's no-load RPM does not exceed this rating before use. The 8,300 RPM rating is designed to accommodate the higher operating speeds typical of compact cordless circular saws.
