CMT 3-Flute Slot Cutter with Arbor and Bearing - 1/8 in. Slot 1/4 Shk

CMT Slot Cutters with Arbor & Bearing – 1/8 in. Slot – 1/4 in. Shank

CMT’s Slot Cutters are designed for creating precise slots for splines, biscuits, T-molding, and other woodworking applications. This cutter includes a 1/4 in. shank arbor and a 7/8 in. diameter bearing, allowing for smooth operation and accurate cutting depths up to 1/2 in.

Safety tips: Always wear a dust mask and eye protection when routing.

Safety precautions: Never use damaged or worn bits. Always operate at the recommended feed rate without forcing the bit. Pay special attention when making the initial cut with a small diameter bit. For best results, make cuts in multiple passes when working with small diameter bits.

How CMT Produces High-Quality Router Bits

• Turning, Milling and Cutting CMT’s continued investment in advanced production technology ensures every router bit is manufactured with precision. Fully automated CNC machinery, operated by specially trained technicians, produces accurately machined and perfectly balanced shanks and bit bodies.
• Heat Forged Steel Bodies for Large Diameter Bits Larger diameter router bits require additional manufacturing steps, including heat forging the steel before precision machining. This process creates a radial grain structure that increases strength, durability, and performance.
• Brazing CMT has pioneered advanced brazing techniques to create a superior bond between steel bodies and carbide tips. Custom computerized brazing equipment and a silver-copper-silver brazing process provide a strong, shock-absorbing connection that helps protect carbide edges during demanding cuts.
• Specially Formulated Carbide for Specific Applications Different woodworking materials require different cutting characteristics. CMT carefully formulates carbide compositions for each application, balancing hardness and impact resistance to deliver optimal cutting performance and durability.
• Grinding and Sharpening The final manufacturing stage uses multi-axis CNC grinding technology to achieve exceptional precision. Every cutting edge is sharpened to exact specifications, producing router bits that deliver razor-sharp performance with long-lasting durability.
