CMT Ultra Finish Plywood and Melamine 250 x 30mm 80-Tooth Hi-ATB Saw Blade is engineered for woodworkers and cabinet makers who demand a glass-smooth finish on double-sided laminated panels, melamine-coated sheet goods, veneered plywood, and chipboard - all without the need for a separate scoring blade. The Hi-ATB (High Alternate Top Bevel) 38 deg. tooth geometry at a -2 deg. negative hook angle produces tear-free crosscuts on both faces of laminated and veneered materials, making it the go-to circular saw blade for fine finish work on panel products. Sized for metric 30mm arbor machines, this blade fits radial arm saws, miter saws, table saws, and special saws used in cabinetry, millwork, and furniture production.

Key Features

• 80-Tooth Hi-ATB 38 deg. Tooth Geometry - the steep alternate top bevel angle shears through melamine, laminate, and veneered plywood fibers cleanly, delivering ultra-smooth cut surfaces on both sides of double-sided panels with virtually zero tearout or chipping.
• -2 deg. Negative Hook Angle - the negative cutting angle slows tooth entry into the material, reducing the risk of grabbing or kickback during crosscuts and producing a controlled, precise finish on brittle laminate surfaces.
• COMBI3 Pin Hole Configuration - the COMBI3 bore pattern ensures positive, accurate blade registration on compatible machines, maintaining precise alignment cut after cut for repeatable dimensional accuracy.
• 30mm Metric Bore Diameter - designed specifically for metric-arbor machines including radial arm saws, miter saws, table saws, and special saws, providing a direct fit without adapter rings that could introduce runout.
• 80 Teeth on a 250mm Diameter - the high tooth count relative to blade diameter maximizes the number of cutting events per revolution, translating directly into smoother cut faces on chipboard, solid wood moldings, and laminates.
• HW (Tungsten Carbide) Tooth Material - industrial-grade carbide tips maintain a sharp cutting edge through extended production runs on abrasive materials like melamine and laminate, reducing downtime for blade changes.
• Rated for Crosscut Applications - optimized geometry for crosscuts means the blade is specifically suited to cutting across the grain and across laminated panel surfaces where tearout is most likely to occur.
• 7,600 Maximum RPM Rating - the blade is rated to handle the higher spindle speeds common on dedicated crosscut and miter machines, giving operators confidence in safe, high-performance operation.

Why This Product

• No scoring blade required for double-sided melamine and laminate - the Hi-ATB 38 deg. tooth grind produces a perfect finish on both faces of double-sided laminated panels in a single pass, eliminating the need for a dedicated scoring blade setup and saving significant setup time on panel processing jobs.
• Purpose-built for metric machines - the 30mm bore with COMBI3 pin hole is sized for the metric-arbor radial arm saws, miter saws, and table saws commonly used in professional cabinetry and millwork shops, providing a direct, stable fit that maximizes cutting accuracy.
• Handles a wide range of sheet and solid materials - from veneered plywood and chipboard to melamine, laminates, solid wood, and moldings, this blade covers the full spectrum of materials found in furniture and cabinet production environments.
• Negative hook angle controls cut entry for safer crosscutting - the -2 deg. hook angle reduces the tendency of the blade to self-feed aggressively into the workpiece, giving the operator greater control and a cleaner finish on fragile laminate surfaces during miter and crosscut operations.

Frequently Asked Questions

Does this blade require a scoring blade to achieve a clean cut on double-sided melamine?

No. The Hi-ATB 38 deg. tooth geometry combined with the -2 deg. negative cutting angle is specifically designed to produce a perfect finish on both sides of double-sided laminated panels in a single pass, without the need for a separate scoring blade.

What machines is this 250mm blade compatible with?

This blade is designed for radial arm saws, miter saws, circular saws, table saws, and special saws equipped with a 30mm metric arbor. The COMBI3 pin hole configuration provides accurate registration on compatible machines.

What materials can be cut with this blade?

The blade is rated for solid wood, moldings, melamine, laminates, veneered plywood, and chipboard. Its 80-tooth Hi-ATB grind makes it especially effective on abrasive laminated and veneered sheet goods where surface quality on both cut faces is critical.

What is the maximum safe operating speed for this blade?

This blade is rated to a maximum of 7,600 RPM. Always verify that your machine's no-load spindle speed does not exceed this rating before use, and consult your machine's documentation for proper blade speed requirements.
