CMT Straight Bit Short Series - 1/2 in. Dia. - 1/4 in. Shank

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

If you want to maximize productivity while achieving clean, precise results, CMT Straight Bits are an essential addition to your router bit collection. Designed for efficient production and dependable performance, these short-series bits feature razor-sharp, double-fluted cutters engineered to deliver smooth, accurate cuts in a wide range of woodworking applications.

Constructed from special Fatigue Proof® steel and high-quality micrograin carbide, CMT Straight Bits are built to withstand demanding workloads while maintaining excellent cutting performance. The cutter geometry promotes efficient chip ejection, helping provide cleaner, more consistent cuts and reducing the buildup of material around the cutting edges.

Each CMT router bit is coated with CMT's trademark orange non-stick PTFE coating. This protective finish helps prevent resin, pitch, and other woodworking residue from adhering to the tool, making the bit easier to maintain and helping preserve smooth operation.

CMT subjects its router bits to strict quality-control testing to ensure accurate cutting tolerances, proper balance, and excellent concentricity. The result is a dependable cutting tool suitable for production work involving plywood, composites, hardwoods, softwoods, and other natural wood materials.

Built for Efficient Routing

• Short-Series Design: Provides a compact cutting profile well suited for a variety of general-purpose routing applications.
• 1/4 in. Shank: Designed for routers and collets that accept a 1/4 in. shank.
• Micrograin Carbide Cutters: Provide sharp, durable cutting edges for smooth and precise material removal.
• Fatigue Proof® Steel: The specially selected steel body is designed to withstand demanding production environments.
• Efficient Chip Ejection: Cutter design helps clear chips effectively for cleaner and more consistent routing.
• Non-Stick PTFE Coating: CMT's distinctive orange coating helps resist resin, pitch, and other residue buildup.
• Precision Manufacturing: Controlled manufacturing processes help maintain balance, concentricity, and cutting accuracy.

How CMT Produces High-Quality Router Bits

CMT combines advanced manufacturing technology with carefully selected materials and precision grinding processes to produce router bits designed for professional woodworking applications.

• Turning, Milling, and Cutting: CMT has invested heavily in modernized production technology. Automated CNC machinery, operated by specially trained personnel, produces accurate shanks and tool bodies while maintaining the balance and precision required for dependable routing performance.
• Heat-Forged Steel Bodies for Large-Diameter Bits: Certain CMT router bits require additional manufacturing steps, including heat forging before the steel is turned into a precision tool body. This process creates a radial grain orientation that provides larger-diameter bits with additional strength and durability.
• Precision Brazing: CMT has pioneered advanced brazing techniques for securing carbide to steel. Computerized brazing equipment helps provide consistent results, while the silver-copper-silver brazing construction creates a strong bond with a degree of shock absorption to help protect carbide tips during demanding cutting operations.
• Specially Formulated Carbide: Different woodworking materials and applications require different carbide characteristics. CMT formulates carbide grades for specific applications, ranging from extremely hard compositions for demanding materials such as laminates to grades designed to better absorb impact when cutting larger profiles.
• Grinding and Sharpening: Precision grinding and sharpening complete the manufacturing process. Advanced equipment is used to produce accurate cutting edges and consistent geometry, helping each bit deliver reliable cutting performance.

Recommended Applications

CMT Straight Bits are versatile tools for general-purpose material removal and precision routing. They can be used with a variety of plywood, composites, hardwoods, softwoods, and natural wood materials. Depending on the specific bit diameter and cutting depth, applications can include trimming, grooving, dadoing, mortising, edge work, and general stock removal.

Safety Precautions

Always inspect the router bit before use. Never operate a damaged, cracked, excessively worn, or otherwise compromised bit. Use the manufacturer's recommended router speed and feed rate, and never force the bit through the material.

Take particular care when making an initial cut with a small-diameter bit. For best results and safer operation with small-diameter cutters, make deeper cuts in multiple passes rather than attempting to remove excessive material in a single pass. Always follow appropriate router, machine, and personal protective equipment guidelines.
