CMT 293.028.14M Ripping Saw Blade - 350 x 3.5 x 30mm, 28-Tooth ATB is a professional-grade carbide-tipped circular saw blade engineered for fast, efficient ripping of hardwood and softwood on production machinery. Built by CMT, this 350mm metric blade delivers clean, aggressive cuts at the table saw, miter saw, radial arm saw, and squaring machines. With a 28-tooth Alternate Top Bevel (ATB) grind and a 20 deg. hook angle, it is purpose-built for high-feed-rate ripping in industrial and trade environments where throughput and cut quality both matter.

Key Features

• 28-Tooth Alternate Top Bevel (ATB 10 deg.) Grind - the ATB tooth geometry creates a shearing action across wood fibers, reducing tear-out on rip cuts in both hardwood and softwood applications.
• 20 deg. Hook (Cutting) Angle - an aggressive hook angle drives the blade through dense hardwood and softwood quickly, supporting high feed rates and improving productivity in production ripping operations.
• 350mm Blade Diameter with 30mm Bore - the metric bore and diameter match metric-arbor stationary and sliding machines, delivering direct, secure mounting without adapters on compatible equipment.
• COMBI3 Pin Hole Configuration - the combination pin hole pattern provides positive blade registration on machines equipped with locating pins, preventing blade creep and improving repeat cut accuracy.
• HW (Tungsten Carbide) Tooth Material - carbide tips maintain a sharp cutting edge through extended production runs on hardwood and softwood, reducing the frequency of blade changes and downtime.
• 5,500 RPM Maximum Speed Rating - the blade is rated for up to 5,500 RPM, supporting use on high-speed industrial table saws, radial arm saws, and squaring machines without risk of over-speeding.
• 3.5mm Kerf / 2.5mm Plate Thickness (0.137" / 0.098") - the optimized kerf-to-plate ratio balances material removal with blade stability, minimizing waste while keeping the blade tracking true under load.

Why This Product

• Designed specifically for ripping - the 28-tooth ATB geometry and aggressive 20 deg. hook angle make this blade the right choice when throughput on long-grain cuts in hardwood and softwood is the priority, rather than a general-purpose or crosscut configuration.
• Metric-native fit for metric machinery - the 350mm diameter and 30mm bore with COMBI3 pin holes eliminate the need for adapter rings or workarounds on metric-arbor miter saws, radial arm saws, table saws, and squaring machines.
• Carbide construction supports sustained production use - the HW tungsten carbide tooth material holds an edge through repeated ripping cycles, making this blade well suited to shop environments where blades are expected to perform across full shifts.
• Broad machine compatibility - the blade is approved for use on miter saws, radial arm saws, stationary and portable table saws, and squaring machines, giving operators flexibility across multiple workstations with a single blade specification.

Frequently Asked Questions

What machines is this 350mm saw blade compatible with?

This blade is approved for use on miter saws, radial arm saws, stationary table saws, portable table saws, and squaring machines. It requires a 30mm metric arbor bore and is compatible with machines that accept the COMBI3 pin hole configuration.

What is the maximum RPM for this blade?

The CMT 293.028.14M is rated for a maximum of 5,500 RPM. Always verify that your machine's no-load RPM does not exceed this rating before mounting the blade.

What does the ATB 10 tooth grind mean for ripping performance?

ATB stands for Alternate Top Bevel - each tooth is beveled in alternating directions at 10 deg. This geometry creates a shearing cut across the wood grain, which helps reduce tear-out and produces a cleaner rip edge on both hardwood and softwood compared to a flat-top grind typically used for rough ripping.

Is this blade suitable for ripping both hardwood and softwood?

Yes. The 293.028.14M is specifically designed for ripping hardwood and softwood. The 28-tooth count, 20 deg. hook angle, and ATB 10 grind work together to support fast, efficient material removal in production ripping applications across both wood types.
