CMT Multi-Rip Saw Blade with Rakers - 12" x 2-3/8" T12+4 Flat is a professional-grade circular rip saw blade from CMT, engineered for industrial multi-rip machines operating with one or two shafts. Designed to slice through both wet and dry soft and hardwood at high production volumes, this pallet and multi-rip blade features integrated raker teeth that keep the steel plate body clear of the workpiece during deep ripping passes - reducing friction, heat buildup, and binding for smoother, more consistent cuts run after run.

Key Features

• Raker teeth (4 rakers alongside 12 cutting teeth) - prevent contact between the steel plate body and the material in use, reducing friction and heat during continuous multi-rip operations so the blade runs cooler and lasts longer between sharpenings.
• Flat Top Grind tooth geometry - optimized for fast, aggressive ripping in both softwood and hardwood, delivering clean rip cuts with minimal fiber tearout in high-throughput production settings.
• 25 deg. hook angle - an aggressive positive hook angle drives material through efficiently on industrial multi-rip machines, maximizing feed rate and cutting productivity.
• 0.157" kerf thickness over a 0.098" plate - the heavy-duty kerf and rigid plate provide stability and controlled cutting power through both wet and dry lumber without blade flex.
• 60.33mm bore diameter with 9.8x6 pin holes - matches the arbor and pin configuration of industrial multi-rip and two-shaft ripping machines for secure, precisely centered mounting.
• Maximum 6,400 RPM rating - supports the high-speed spindle speeds common on industrial multi-rip equipment, ensuring safe operation at full machine capacity.
• HW (tungsten carbide) tooth material - hard-wearing carbide tips maintain sharp cutting edges longer than standard steel teeth, reducing downtime for blade changes in demanding production environments.

Why This Product

• Built specifically for industrial multi-rip machines with one or two shafts - the bore size, pin hole configuration, and tooth count are matched to production-grade ripping equipment, not consumer table saws, so it mounts correctly and performs as intended.
• The raker tooth design solves a common problem in deep multi-rip work: the steel plate binding against the kerf walls. By keeping the body clear of the cut, rakers reduce heat and drag, which extends blade life and improves cut quality through both wet and dry hardwood and softwood.
• With a 6,400 RPM maximum rating, this blade is rated for the high-speed spindle demands of industrial ripping lines - operators do not need to derate or slow down their machines to accommodate blade limitations.
• The combination of an aggressive 25 deg. hook angle and flat top grind teeth makes this blade well suited to high-volume ripping applications such as pallet manufacturing and dimensional lumber breakdown, where feed rate and throughput matter as much as cut quality.

Frequently Asked Questions

What is the purpose of the raker teeth on this blade?

The raker teeth prevent contact between the steel plate body and the material being cut. During multi-rip operations - especially through thicker or wet lumber - the kerf walls can press against the blade body, causing friction, heat, and binding. The rakers hold the material away from the plate so the blade body does not rub against the cut, resulting in smoother operation and reduced heat buildup.

Is this blade compatible with both single-shaft and two-shaft multi-rip machines?

Yes. According to the product data, this blade is designed for use on multi-rip machines with one or two shafts. The 60.33mm bore and 9.8x6 pin hole configuration supports the arbor and pin arrangements common on industrial multi-rip equipment.

Can this blade cut wet lumber?

Yes. This blade is rated for cutting both wet and dry soft and hardwood. The flat top grind tooth geometry and raker design are suited to the demanding conditions of wet lumber ripping, which is common in pallet manufacturing and green lumber processing.

What does the flat top grind tooth geometry mean for ripping performance?

A flat top grind (also called flat top grind or FTG) means each tooth has a flat cutting face rather than an angled or beveled face. This geometry is the standard for aggressive ripping cuts along the grain of wood. Combined with the 25 deg. positive hook angle on this blade, the flat top grind shears fibers efficiently during high-feed-rate production ripping in both softwood and hardwood.
