The CMT Orange Chrome Crosscut Fine Finish Saw Blade - 18" x 1" Bore - 108-Tooth ATB is engineered for large-capacity crosscutting applications where surface quality matters. With 108 alternating top bevel teeth ground to 15 deg. and a 10 deg. hook angle, this blade delivers fine finish results on hardwood, softwood, plywood, melamine, and chipboard. Designed for use on miter saws, slide miter saws, stationary table saws, and portable table saws, it suits professional woodworking environments demanding clean, splinter-free cuts across a range of panel and solid wood materials.

Key Features

• 108-Tooth ATB Geometry at 15 deg. - the high tooth count combined with alternating top bevel sharpening produces fine finish crosscuts, minimizing tear-out on hardwood, softwood, plywood, melamine, and chipboard surfaces.
• 18" Diameter Blade - accommodates large-capacity crosscutting passes on stationary table saws and slide miter saws, making it suitable for wide boards and full-size sheet goods.
• 1" (25.4mm) Bore Diameter - fits standard arbors found on stationary and portable table saws as well as miter saws, providing broad machine compatibility without adapters.
• 10 deg. Hook Angle - a controlled, low-aggression hook angle reduces grabbing and kickback tendency during crosscuts, contributing to smoother, more controlled feed and improved operator safety.
• 0.150" Kerf / 0.110" Plate Thickness - the kerf-to-plate ratio provides structural rigidity while managing material waste, supporting stable tracking through dense hardwood and composite panel materials.
• Hardmetal (HW) Tooth Material - carbide-tipped teeth retain their edge longer through repeated use on abrasive materials like melamine and chipboard, extending blade service life between resharpenings.
• 4,200 RPM Rating - the blade is rated for up to 4,200 RPM, ensuring compatibility with the high-speed spindles found on professional stationary machines.

Why This Product

• When a fine finish on crosscuts is the priority - rather than ripping - the 108-tooth ATB configuration is purpose-built for that outcome, reducing the need for sanding or secondary cleanup on hardwood, melamine, and veneered plywood edges.
• The 18" diameter fills a specific need for large-capacity cuts that smaller blades cannot reach, making it a practical choice for shops running wide stock or full-panel crosscuts on stationary table saws and slide miter saws.
• Hardmetal (HW) carbide tips hold their edge through demanding, repeated cuts on abrasive composite materials like chipboard and melamine - reducing downtime for resharpening compared to standard steel blades.
• With a 4,200 RPM maximum speed rating and compatibility across multiple machine types - miter saws, slide miter saws, stationary table saws, and portable table saws - this blade adapts to varied professional shop setups without requiring a dedicated machine.

Frequently Asked Questions

What machines is this 18" saw blade compatible with?

This blade is designed for use on miter saws, slide miter saws, stationary table saws, and portable table saws. The 1" (25.4mm) bore fits the standard arbors found on these machine types.

What does the ATB tooth geometry mean for my cuts?

ATB stands for Alternate Top Bevel - each tooth alternates between a left and right bevel angle, in this case ground to 15 deg. This geometry is optimized for fine finish crosscutting, producing cleaner edges on hardwood, softwood, plywood, melamine, and chipboard with minimal tear-out.

What is the maximum safe operating speed for this blade?

This blade is rated for a maximum of 4,200 RPM. Always verify that your machine's spindle speed does not exceed this rating before use.

What materials can this blade cut?

According to the product data, this blade is suited for crosscutting hardwood and softwood, as well as cutting plywood, melamine panels, and chipboard. It is categorized as a fine finish crosscut blade, so it is optimized for clean cuts rather than ripping along the grain.
