CMT Industrial Plexiglass and Plastic Saw Blade - 10" x 5/8" with 80 Teeth (MATB) is a professional-grade circular saw blade engineered by CMT for heavy-duty cutting and smooth finishing of plastic materials without melting or chipping. Built with a Modified Alternate Top Bevel (MATB) tooth grind and a -3 deg. negative hook angle, this blade is purpose-built for clean, precise results when working with thin plastic sheeting, plexiglass, phenolic, vinyl, laminate flooring, and plywood. The XTreme industrial design delivers consistent performance across radial arm saws, miter saws, table saws, and specialty cutting machines.

Key Features

• 80-Tooth Modified Alternate Top Bevel (MATB) Grind - the high tooth count combined with MATB geometry produces exceptionally smooth, clean edges on plexiglass and plastics, minimizing surface chipping and tearout that would otherwise require additional finishing work.
• -3 deg. Negative Hook Angle - reduces aggressive feed rate and keeps the blade from grabbing or melting soft plastic materials during the cut, resulting in smoother, safer passes through vinyl, laminate flooring, and thin sheeting.
• 0.110" Kerf / 0.087" Plate Thickness - a controlled kerf width limits material waste and heat buildup, while the thinner plate reduces drag and allows the blade to move efficiently through phenolic and plywood stock.
• 5/8" Bore Diameter - fits the standard arbor size used on most 10" table saws, miter saws, and radial arm saws, making mounting straightforward without requiring adapters in most shop setups.
• 7,600 Maximum RPM Rating - supports high-speed operation on powerful machines, giving professional users the throughput they need for heavy-duty production cutting of plastics and laminate flooring.
• Hardened Metal (HW) Carbide Tooth Material - industrial-grade carbide tips retain a sharp edge through extended use on abrasive materials like phenolic and plexiglass, reducing how often the blade needs to be resharpened.
• CMT XTreme Industrial Classification - designed for demanding professional applications where consistent cut quality and tool longevity matter across long production runs.

Why This Product

• The -3 deg. negative hook angle and MATB tooth grind work together specifically to prevent the heat buildup and melting that commonly occurs when cutting plexiglass and vinyl with general-purpose saw blades - this is a blade designed from the geometry up for plastic and laminate materials.
• With an 80-tooth configuration rated to 7,600 RPM, this blade handles both smooth finish cuts and heavy-duty production volume on radial arm saws, miter saws, and table saws without requiring a blade change between operations.
• The 5/8" bore diameter and 10" diameter match the most common arbor configuration found on 10" contractor and cabinet table saws, meaning this blade slots directly into existing machine setups with no additional hardware in most cases.
• The HW carbide construction is suited to the abrasive nature of phenolic panels, plexiglass, and laminate flooring - materials that dull standard steel blades quickly - extending time between resharpening cycles in high-use shop environments.

Frequently Asked Questions

Why does this blade use a negative hook angle instead of a standard positive hook angle?

The -3 deg. negative hook angle is intentional for cutting plastic, plexiglass, and vinyl. A negative hook angle slows the feed rate and reduces the tendency of the blade to grab the material aggressively, which helps prevent melting, cracking, or chipping at the cut edge - problems that are common when plastic is cut with blades designed for wood.

What materials is this blade approved to cut?

This blade is designed to cut thin plastic, phenolic, plexiglass, vinyl, laminate flooring, and plywood. It is not a general-purpose wood blade - the tooth geometry and hook angle are optimized specifically for plastic and laminate-type materials.

What machines is this 10" blade compatible with?

This blade is compatible with radial arm saws, miter saws, table saws, and special saws fitted with a 5/8" arbor. The maximum rated speed is 7,600 RPM, so confirm your machine does not exceed this rating before mounting the blade.

What does MATB tooth grind mean and why does it matter for plastic cutting?

MATB stands for Modified Alternate Top Bevel. This sharpening pattern alternates the bevel angle on successive teeth in a modified pattern, which helps produce a clean, smooth shear cut through plastics and laminates. The geometry reduces the chipping and rough edges that occur with flat-top or standard alternate top bevel grinds when used on brittle or soft plastic materials.
