The CMT ITK General Purpose Saw Blade - 12 inch x 1 inch, 48 Tooth ATB is a professional-grade carbide-tipped circular saw blade engineered for versatile cutting across a wide range of wood-based materials. Designed for use in miter saws, corded circular saws, and cordless circular saws, this blade delivers smooth, accurate results whether you are ripping dimensional lumber, crosscutting hardwood, or slicing through OSB, pressure-treated stock, and laminated beams. The Alternate Top Bevel tooth geometry at 15 deg. with a -10 deg. hook angle produces clean entry and exit cuts, reducing tearout and keeping material edges crisp across both hardwood and softwood applications. Built to ITK Xtreme standards, this blade is a dependable general-purpose choice for jobsite and shop use alike.

Key Features

• ATB 15 deg. Tooth Grind - the Alternate Top Bevel geometry at 15 deg. sharpens each tooth to a precise angle that shears wood fibers cleanly, reducing tearout on both rip cuts and crosscuts in hardwood and softwood.
• -10 deg. Hook Angle - the negative hook angle controls feed rate and reduces grabbing, which improves safety and cut quality especially when working with a miter saw or cordless circular saw.
• Tri-Metal Silver-Copper-Silver Brazing - the special Silver-Copper-Silver Tri-Metal Brazing process bonds carbide teeth to the plate with exceptional strength, allowing the blade to handle high stress and impact when cutting harder woods and composite materials without tooth loss.
• Special Straightening Processes for Blade Body Flatness - blade body flatness is obtained via special straightening processes that guarantee exceptionally reduced tolerances, resulting in a stable, wobble-free cut.
• Full Blade Balancing - balancing performed on all saw blades guarantees maximum stability, reducing vibration transferred to the saw and the operator during extended cutting sessions.
• HW (Tungsten Carbide) Tooth Material - hardmetal carbide tips stay sharp longer than standard steel teeth, extending the service life of the blade across repeated cuts in demanding materials such as pressure-treated lumber and laminated beams.
• 0.110 in. Kerf with 0.071 in. Plate - the kerf-to-plate ratio provides adequate tooth set for chip clearance while keeping material waste low, making this blade efficient for production cutting.
• 6,400 RPM Rating - the high maximum RPM rating ensures compatibility with fast-spinning cordless and corded circular saws and miter saws, giving you flexibility across your tool inventory.
• 1 in. Bore Diameter (25.4mm) - the standard 1 in. arbor bore fits the majority of 12 in. miter saws and table saws without requiring an adapter ring, making installation straightforward.

Why This Product

• One blade handles hardwood, softwood, OSB, pressure-treated lumber, and laminated beams - so you can move through mixed-material projects without stopping to swap blades.
• The Tri-Metal Silver-Copper-Silver Brazing holds carbide teeth securely under the high stress and impact that occur when cutting harder woods and composite materials, reducing the risk of tooth separation and premature blade retirement.
• Blade body flatness obtained via special straightening processes and full blade balancing work together to deliver exceptionally reduced tolerances and maximum stability - critical for accurate miter cuts and clean finish work.
• Rated to 6,400 RPM and compatible with cordless circular saws, corded circular saws, and miter saws, this blade transitions easily from a jobsite cordless tool to a shop miter saw without requiring a separate blade for each machine.

Frequently Asked Questions

What saws is this 12 in. blade compatible with?

This blade is designed to fit cordless circular saws, corded circular saws, and miter saws with a standard 1 in. (25.4mm) arbor and a 12 in. blade capacity. Always confirm your saw's arbor size and blade diameter rating before installing.

What is the maximum RPM for this blade?

This blade is rated for a maximum of 6,400 RPM. Never exceed the blade's maximum RPM rating - always verify that your saw's no-load RPM does not exceed this value before use.

Why does this blade use a negative hook angle?

The -10 deg. hook angle controls how aggressively the teeth pull into the material. A negative hook angle reduces grabbing and self-feeding, which is especially beneficial when using a miter saw or cordless circular saw where controlled, smooth feeding is important for safety and cut quality.

What materials can this blade cut?

This blade is suited for cutting hardwood, softwood, OSB, pressure-treated lumber, and laminated beams. The 48-tooth ATB configuration and Tri-Metal Brazing make it capable of handling both general ripping and crosscutting tasks across these material types.
