CMT ITK Plus Ultra Finish Saw Blade - 160x20mm, 56 Tooth by CMT is engineered for precision crosscutting in hardwood, softwood, plywood, OSB, and melamine. Featuring a combined ATB plus shear tooth geometry, this 160mm metric circular saw blade is purpose-built for track saws and metric-arbor machines, delivering glass-smooth surfaces and virtually zero tearout on even the most demanding finish cuts. The 56-tooth configuration and fine kerf make it an ideal choice wherever ultra-clean cuts and surface quality are the priority.

Key Features

• 56-Tooth ATB plus Shear Geometry (10 deg. ATB + 8 deg. Shear) - the combined alternate top bevel and shear angle slices fibers cleanly from both sides of the cut, producing ultra-smooth surfaces with minimal tearout in hardwood, softwood, and panel materials.
• 12 deg. Cutting (Hook) Angle - a positive hook angle feeds the blade efficiently through stock while keeping the cut under control, reducing the effort required on plunge and track saw applications.
• 160mm Diameter with 20mm Bore (plus 16mm reduction ring) - fits the standard metric arbor used by Festool and other European track saw systems, giving users precise compatibility without adapter guesswork.
• 0.071 in. Kerf / 0.047 in. Plate Thickness - the thin kerf design removes less material per pass, reducing strain on cordless and lower-powered machines and extending battery runtime on cordless circular saws.
• Pin Hole Configuration 2/6/32 - matches the locating pin patterns found on a wide range of metric miter saws and track saws, ensuring the blade seats precisely and runs true.
• HW (Hardmetal/Carbide) Tooth Material - industrial-grade carbide tips hold a sharp cutting edge longer than standard steel teeth, meaning fewer blade changes and consistently clean results over extended use.
• Precision Sharpening on Every Tooth - each tooth is sharpened to tight tolerances so the blade performs consistently from the very first cut through its full service life.
• Laser-Cut Steel Plate - laser cutting produces a plate with tight dimensional tolerances, contributing to stable, vibration-free tracking and accurate, repeatable cut lines.

Why This Product

• Optimized for track saws and metric-arbor machines - the 160mm diameter, 20mm bore, and included 16mm reduction ring address the exact arbor and diameter requirements of Festool-style track saw systems, eliminating the need for non-standard adapters.
• Ultra-finish results on a wide range of panel and solid materials - the 56-tooth count combined with ATB plus shear geometry means the blade handles hardwood, softwood, plywood, OSB, and melamine cleanly in a single setup, reducing the need to swap blades between material types.
• Thin-kerf design suits cordless and lower-powered circular saws - at 0.071 in. kerf, the blade minimizes cutting resistance, making it well-suited for battery-powered tools where efficiency and runtime matter.
• HW carbide construction sustains cut quality over time - hardmetal-tipped teeth stay sharp longer under repeated crosscutting, making this blade a reliable choice for production cabinetry, finish carpentry, and panel processing applications.

Frequently Asked Questions

What machines is this 160mm blade compatible with?

This blade is designed for track saws and metric-arbor circular saws that accept a 160mm blade diameter. The 20mm bore with an included 16mm reduction ring provides compatibility with a range of European-style machines including Festool-format track saws, as well as miter saws and slide miter saws that use a 16mm or 20mm arbor.

What does the ATB plus Shear tooth geometry mean in practice?

ATB stands for Alternate Top Bevel - teeth are angled alternately left and right across the blade. The additional 8 deg. shear angle sharpens the slicing action at the point where the tooth enters the material. Together, these two geometric elements sever wood and panel fibers cleanly from both sides of the kerf, which is what produces ultra-fine, tearout-free surfaces on crosscuts in hardwood, softwood, plywood, and melamine.

Is this blade suitable for use with cordless circular saws?

Yes. The thin kerf of 0.071 in. reduces the amount of material removed per pass, which directly lowers the cutting resistance the motor must overcome. This makes the blade well-suited for cordless circular saws where managing power consumption and battery runtime is important.

What is the pin hole specification and why does it matter?

The pin hole configuration for this blade is 2/6/32. Pin holes are small locating holes near the bore that engage with corresponding pins on certain saw flanges or arbors. Matching the correct pin hole pattern ensures the blade is positively located and runs with minimal runout, which directly supports accurate, repeatable cuts.
