CMT ITK Plus Ultra Finish Saw Blade 165x20mm T56 by CMT is a high-tooth-count circular saw blade engineered for ultra-smooth crosscuts in hardwood, softwood, plywood, OSB, and melamine. The 56-tooth ATB with shear geometry produces glass-smooth surfaces and dramatically reduced tearout, making this 6-1/2 in. blade the right choice for finish carpentry, cabinet work, and precision panel cutting. Designed to fit track saws and machines with a 20mm metric arbor, it delivers the kind of accuracy that demanding woodworkers expect from a premium carbide-tipped blade.

Key Features

• 56-Tooth ATB with 8 deg. Shear Geometry (15 ATB + 8 Shear) - the combination of alternate top bevel and shear angle slices wood fibers cleanly rather than tearing them, resulting in ultra-fine finish cuts on veneered panels, melamine, and hardwood with minimal chipping or fraying.
• 12 deg. Cutting (Hook) Angle - the positive hook angle helps the teeth engage the material aggressively yet smoothly, reducing motor strain on cordless circular saws and track saws while maintaining feeding control.
• 0.063 in. Kerf with 0.039 in. Plate - the thin kerf removes less material per pass, reducing waste and demanding less power from the saw - particularly useful for cordless and battery-powered tools where preserving runtime matters.
• 20mm Bore with Reducer Options (+15.88mm) - the metric bore fits track saw systems and metric-arbor machines directly, and the included reducer compatibility means the blade adapts to additional tool configurations without extra hardware.
• Maximum 9,500 RPM Rating - rated for the high spindle speeds common in track saws and compact circular saws, so the blade performs safely and consistently at the operating speeds these tools deliver.
• HW (Hardmetal/Carbide) Tooth Material - tungsten carbide tips retain their edge through extended use in hardwood and abrasive sheet goods like OSB and melamine, extending the interval between resharpenings and lowering the cost per cut over time.
• 2/6/32 Pin Hole Configuration - matches the locating pin arrangements found on common track saw and metric-arbor platforms, ensuring precise, repeatable blade positioning every time the blade is installed.

Why This Product

• The 56-tooth count paired with ATB and 8 deg. shear geometry is specifically configured for ultra-finish crosscutting - meaning woodworkers and finish carpenters get cut quality that often eliminates the need for sanding or secondary cleanup on veneered plywood, melamine, and hardwood panels.
• At 6-1/2 in. (165mm) diameter with a 20mm metric bore, this blade fits the track saw format that site carpenters and shop workers use for controlled, guided cuts - a combination not served by standard imperial-arbor blades.
• The thin 0.039 in. plate and 0.063 in. kerf reduce material removal and cutting resistance, which translates directly to longer battery life on cordless saws and less strain on compact motors during extended sheet-goods processing.
• With a maximum rating of 9,500 RPM and carbide tooth material graded for hardwood, OSB, and melamine, this blade covers the range of materials a cabinet maker or finish installer encounters in a typical workday - hardwoods, softwoods, veneered sheet goods, and coated panels - without switching blades.

Frequently Asked Questions

What machines is this blade compatible with?

This blade is designed for track saws and circular saws with a 20mm metric arbor. The bore also accommodates a 15.88mm reducer, expanding compatibility to additional tool configurations. The 2/6/32 pin hole pattern matches the locating pin arrangements on common track saw platforms.

What does the ATB + Shear tooth geometry actually do for cut quality?

The 15 deg. ATB sharpening angle creates an alternate bevel that scores the wood fibers on each side of the kerf, while the additional 8 deg. shear angle causes the tooth to slice into the material at a diagonal rather than chop straight in. Together, these geometry choices produce the ultra-smooth, low-tearout finish the blade is designed for - particularly important when cutting melamine, veneered plywood, and hardwood where surface quality matters.

Is this blade suitable for use with cordless circular saws?

Yes. The thin kerf (0.063 in. teeth thickness, 0.039 in. plate) reduces cutting resistance and material removal per pass, which lowers the power demand on the motor. This makes the blade well suited to cordless circular saws where conserving battery runtime and avoiding motor overload is a practical concern. The maximum rated speed is 9,500 RPM, which covers the spindle speeds typical of cordless compact circular saws and track saw systems.

Can this blade be resharpened?

The blade uses HW (hardmetal - tungsten carbide) tooth material, which is a resharpenable grade. Carbide-tipped blades with this class of tooth material are generally able to be professionally resharpened multiple times before replacement is needed, helping extend the useful life of the blade over repeated use in hardwood, OSB, and melamine applications.
