Product Description
The CMT Chrome Fine Finish Sliding Compound Saw Blade - 12 in. x 1 in. Bore, 80-Tooth ATB is engineered for woodworkers and finish carpenters who demand splinter-free, ultra-smooth crosscuts on demanding materials. Designed specifically for sliding compound miter saws and stationary or portable table saws, this 80-tooth alternate top bevel blade handles hardwood, softwood, plywood, melamine, and chipboard with precision and consistency. The slim 0.071 in. plate and 0.094 in. kerf work together to minimize material waste while reducing the load on your saw motor - making every cut cleaner and more efficient.
Key Features
- 80-Tooth ATB 15 deg. Grind - the high tooth count combined with a 15 deg. alternate top bevel geometry slices cleanly through wood fibers, melamine faces, and laminate surfaces, reducing tear-out and eliminating the need for secondary sanding or finishing passes.
- 5 deg. Hook Angle - a slight positive hook angle promotes controlled, smooth feed rates through dense hardwoods and composite sheet goods, helping prevent grabbing or chipping on delicate surfaces.
- 0.094 in. Kerf / 0.071 in. Plate Thickness - a thin kerf design reduces the amount of material removed per pass and lowers motor strain, allowing your miter saw or table saw to work more efficiently with cleaner results.
- 1 in. (25.4 mm) Bore Diameter - fits the standard arbor size used on most sliding compound miter saws and table saws, providing solid, centered blade seating for vibration-free operation.
- 6,400 RPM Rating - rated for high-speed operation to match the demands of professional sliding compound miter saws, ensuring safe, stable performance throughout the cut.
- HW (Tungsten Carbide) Tooth Material - hard-wearing carbide tips hold a sharp edge longer than standard steel teeth, extending blade life and maintaining cut quality over hundreds of passes through hardwood and engineered sheet materials.
- 12 in. Diameter - full 12 in. cutting capacity suits large sliding miter saws and table saws, allowing wide crosscuts and deep bevel angles in a single pass.
Why This Product
- With 80 ATB teeth and a 15 deg. bevel grind, this blade is purpose-built for fine finish crosscutting - ideal when working with melamine, chipboard, or finished hardwood where surface quality directly affects the final result.
- The thin 0.071 in. plate and 0.094 in. kerf make this a smart choice for sliding compound miter saw users who need precise, low-waste cuts in expensive hardwoods or veneered sheet goods.
- Rated to 6,400 RPM and compatible with sliding compound miter saws as well as stationary and portable table saws, this blade adapts across multiple machines without compromise, reducing the number of specialty blades a shop needs to maintain.
- The combination of a 5 deg. hook angle with high tooth count means the blade handles everything from dense hardwoods to delicate laminate edges - minimizing chipping and delivering results that typically require minimal cleanup work.

Frequently Asked Questions
What machines is this blade compatible with?
This 12 in. blade is designed for use on sliding compound miter saws, stationary table saws, and portable table saws. The 1 in. (25.4 mm) bore fits the standard arbors found on most of these machines. Always verify your saw's maximum blade diameter and arbor size before mounting.
Why does this blade have 80 teeth instead of a lower count, and what difference does it make?
Higher tooth counts produce finer, smoother cuts with less tear-out - which is exactly what fine finish crosscutting in hardwood, melamine, plywood, and chipboard demands. The 80 ATB teeth combined with the 15 deg. alternate top bevel grind allow each tooth to shear cleanly through material rather than chipping it, making this the right choice when surface quality matters most.
What does the 6,400 RPM rating mean for my saw?
The maximum RPM rating indicates the highest safe operating speed for this blade. You should never use this blade on a machine whose no-load speed exceeds 6,400 RPM. Most 12 in. sliding compound miter saws operate well within this range, making the blade a safe and appropriate fit for standard shop use.
What is the difference between kerf thickness and plate thickness, and why does it matter?
The plate thickness (0.071 in.) refers to the body of the blade itself, while the kerf thickness (0.094 in.) is the width of the cut made by the carbide teeth, which extend slightly beyond the plate on each side. The difference between these two measurements represents the tooth set. A thinner kerf removes less material per cut, reducing waste and motor load - a meaningful advantage when cutting expensive hardwoods or working with a portable table saw with a smaller motor.
