CMT Straight Bit Long Series - 1/4 in. Dia. - 1/4 in. Shank

CMT Straight Bit Long Series - 1/4 in. Shank

Get efficient, reliable routing performance with the CMT Straight Bit Long Series. Designed for clean, accurate stock removal, this 1/4 in. diameter router bit features a 1/4 in. shank and an extended cutting length for routing applications that require additional reach. Its razor-sharp, double-faced cutting edges deliver smooth, precise results while helping maintain consistent performance through demanding woodworking projects.

Manufactured from special Fatigue Proof® steel and high-quality micrograin carbide, CMT straight bits are engineered to withstand demanding workloads while maintaining excellent cutting performance. The optimized cutting geometry provides efficient chip ejection, helping produce cleaner cuts and more consistent results in plywood, composite materials, hardwoods, softwoods and natural woods.

The bit body is finished with CMT's trademark orange non-stick PTFE coating, which helps reduce the buildup of resin, pitch and other cutting residue. This coating keeps the cutting surfaces cleaner during use and helps reduce friction for smoother routing performance. Each CMT router bit is subjected to strict quality-control testing to ensure accurate cutting tolerances, balance and concentricity.

Ideal for a Variety of Materials

CMT straight router bits are suitable for a broad range of woodworking and production applications. Use this bit for routing natural woods, hardwoods, softwoods, plywood and composite materials. Its durable carbide cutting edges make it a dependable choice for both professional woodworking and demanding production environments.

How CMT Produces High-Quality Router Bits

• Turning, Milling and Cutting – CMT continues to invest in advanced manufacturing technology and automated production equipment. CNC machinery operated by specially trained personnel helps ensure that router-bit shanks and bodies are manufactured with exceptional accuracy and balance.
• Heat-Forged Steel Bodies for Large-Diameter Bits – Certain CMT router bits require additional manufacturing processes, including heat forging the steel before forming the precision bit body. This process creates a radial grain orientation that provides additional strength and durability where required.
• Precision Brazing – CMT's specialized computerized brazing equipment helps provide consistent bonding between the steel body and carbide. A silver-copper-silver brazing sandwich creates a strong connection while providing a shock-absorbing effect that helps protect carbide cutters during demanding applications.
• Specially Formulated Carbide – Different woodworking materials require different cutting characteristics. CMT formulates carbide grades for specific applications, balancing hardness, toughness and wear resistance to provide the appropriate performance for each tool.

Safety Tips

Dust and chips from laminate and composite materials can be hazardous to your health and safety. Always wear appropriate personal protective equipment, including a properly fitted dust mask or respirator and eye protection, when operating a router.

Safety Precautions

• Never use router bits that are damaged, cracked, bent or excessively worn.
• Always operate the router bit at the manufacturer's recommended RPM and feed rate.
• Do not force the router bit through the workpiece. Allow the cutting edges to remove material at the proper feed rate.
• Pay particular attention when making the initial cut with small-diameter router bits.
• For best results with small-diameter bits, make deep cuts in multiple passes rather than attempting to remove excessive material in a single pass.
• Make sure the bit is properly secured in the router collet before operation.
• Keep hands clear of the cutting area and follow all router manufacturer's safety instructions.
