CMT Straight Bit Short Series - 3/4 in. Dia. - 1/4 in. Shank

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

The CMT Straight Bit Short Series is designed for efficient, accurate routing when you need fast material removal without sacrificing the quality of the finished edge. With a 3/4 in. diameter and 1/4 in. shank, this straight router bit is well suited for routing grooves, dados, mortises, recesses, and other general-purpose woodworking applications in a wide range of materials.

CMT straight bits feature razor-sharp, double-faced carbide cutters engineered to deliver clean, precise cuts and efficient chip removal. Manufactured from special Fatigue Proof® steel and micrograin carbide, these bits are built to withstand demanding workloads while maintaining consistent cutting performance. The optimized cutter design promotes excellent chip ejection, helping provide smoother and more controlled routing.

Each CMT router bit is coated with the company's trademark orange non-stick PTFE coating. This protective surface helps reduce the buildup of resin, pitch, and other woodworking residue, keeping the cutting surfaces cleaner during use and making the bit easier to maintain.

CMT puts every router bit through strict quality-control testing to ensure excellent cutting tolerance, balance, and concentricity. The result is a dependable cutting tool capable of delivering repeatable performance in plywood, composites, and natural woods, whether used for individual woodworking projects or demanding production environments.

Precision Manufacturing for Reliable Performance

CMT invests heavily in advanced manufacturing technology to produce router bits with precise dimensions and excellent balance. Automated CNC machinery, operated by specially trained technicians, is used to accurately machine router-bit shanks and bodies. This precision helps ensure dependable performance and smooth operation during routing.

Heat-Forged Steel Bodies

For larger-diameter tools, CMT uses heat-forging processes before machining the steel into precise bit bodies. The resulting radial grain orientation provides additional strength and durability, helping the tool withstand the stresses associated with demanding cutting applications.

Advanced Brazing: Technology

CMT has pioneered advanced brazing techniques for securely bonding carbide to steel. Computer-controlled brazing equipment helps provide consistent results, while the silver-copper-silver brazing sandwich creates a strong bond with a shock-absorbing effect. This construction helps protect the carbide cutters from impact when routing harder woods and other demanding materials.

Application-Specific Carbide

Different woodworking materials place different demands on a cutting tool. CMT therefore formulates carbide grades specifically for individual applications. Depending on the intended use, carbide compositions can be engineered for exceptional hardness when cutting tough laminates or formulated to absorb greater impact when cutting larger profiles.

Precision Grinding and Sharpening

The final grinding and sharpening processes are performed to extremely precise tolerances. Accurate grinding helps establish the cutting geometry required for clean, consistent routing performance while maintaining the balance and concentricity expected from a professional-quality CMT router bit.

Safety Precautions

• Never use damaged, cracked, or worn router bits.
• Always operate the router bit at the manufacturer's recommended speed and feed rate.
• Do not force the bit through the material; allow the cutter to remove material at an appropriate rate.
• Use particular care when making the initial cut with smaller-diameter router bits.
• When working with small-diameter bits, make deeper cuts through multiple passes rather than attempting to remove excessive material in a single pass.
• Always use appropriate eye, hearing, and respiratory protection and follow the safety instructions for your router and work material.

Built for Clean, Consistent Routing

Whether you're producing grooves and dados, removing stock, creating recesses, or performing other general routing operations, the CMT Straight Bit Short Series 3/4 in. Dia. x 1/4 in. Shank combines durable construction, precision-ground carbide, efficient chip removal, and a non-stick protective coating to provide reliable performance. It is a practical addition to any woodworking router-bit collection where clean cuts, durability, and repeatable results matter.
