CMT 2 Flute Downcut Spiral Router Bit - 1/4" Diameter, 1" Cut, 1/4" Shank

This downcut router bit provides an excellent finish on the upper sides of workpieces. It features a special super-micrograin carbide formulation that was created to product and hold a keen cutting edge. The low-angle spiral is designed specifically to shear wood cleanly and provide efficient chip ejection. The tools run cooler and the edges last longer.

Used for cutting, copying, panel sizing and any routing applications on solid wood, wood composites, plastic materials, and laminates. Use a high feed speed on well-clamped workpieces. Can be used on machining centers, point-to-point boring machines, CNC routers, and hand-held routers equipped with chucks or adaptors.

The main components of CMT Router Bits are just two: steel and carbide. CMT's steel comes from Switzerland, where an exclusive hot drawing process is applied to forge the solid bar stock they use to manufacture the shanks and bodies. The result is superior strength steel that is exceptionally resistant to fatigue and abrasion. The tips of their bits are made from premium micrograin carbide that lasts longer and cuts accurately.

Why CMT Router Bits?

• Multi-Axis Grinding: Each cutting edge is ground to micron-level accuracy, producing a razor-sharp edge and a true mirror finish. The result is cleaner cuts, less tear-out, and significantly longer edge life, even in dense hardwoods.
• Anti-Kickback Design: Engineered cutting geometry controls chip load and limits how aggressively the bit engages the material. This improves operator control and reduces the risk of kickback.
• Hi-Density Industrial Chrome Carbide: Hot Isostatic Pressing eliminates microscopic voids in the carbide, creating a denser, more uniform cutting edge that resists chipping and holds sharpness longer.
• Tri-Metal Brazing: A Silver–Copper–Silver brazing system creates a stronger bond between carbide and steel while absorbing cutting vibration. This protects the cutting edge and improves performance in hardwoods and composite materials.
• Non-Stick Orange Shield Coating: Reduces heat and pitch buildup, resists corrosion, and keeps the bit cutting freely for longer service life.
• Superior High-Strength Steel: Manufactured from premium Swiss-sourced steel bar stock for superior balance, fatigue resistance, and vibration control at high RPMs.
