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

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

If you are looking to get the most out of your time and money through more efficient production, while still demanding a beautiful, clean edge on your finished piece, the CMT Straight Bit Long Series is an excellent addition to your router bit collection. Designed for demanding woodworking applications, this razor-sharp, double-fluted cutter combines durable construction, precision manufacturing, excellent chip ejection, and long-lasting performance.

Made from special Fatigue Proof® steel and high-quality micrograin carbide, this CMT straight router bit is engineered to withstand heavy workloads while delivering smooth, accurate cuts. The cutting geometry provides efficient chip removal for cleaner and more consistent routing, making the bit suitable for a wide range of plywood, composites, and natural woods.

The bit features CMT’s trademark orange non-stick PTFE coating, which helps reduce the buildup of resin, pitch, and other cutting residue on the surface. This coating helps maintain smooth operation and makes the bit easier to clean after use. Every CMT router bit is subjected to strict quality testing to ensure excellent cutting tolerance, balance, and concentricity.

With a 1/2 in. cutting diameter, long-series cutting profile, and 1/4 in. shank, this router bit is well suited for applications requiring extended cutting depth and dependable stock removal. It can be used for routing grooves, dados, mortises, and other straight-sided profiles where a clean and precise cut is required.

Key Features

• 1/2 in. Diameter: Provides a substantial cutting profile for efficient material removal and accurate straight cuts.
• Long Series Design: Offers extended cutting capability for applications requiring greater cutting depth.
• 1/4 in. Shank: Compatible with routers and collets designed to accept 1/4 in. shanks.
• Micrograin Carbide Cutters: Provides sharp, durable cutting edges for smooth and precise routing.
• Fatigue Proof® Steel: Durable steel construction helps the bit withstand demanding production environments.
• Excellent Chip Ejection: Helps remove chips efficiently for cleaner, more consistent cutting.
• Non-Stick PTFE Coating: CMT’s orange coating helps resist resin, pitch, and other residue buildup.
• Precision Manufacturing: Strict quality controls help ensure balance, concentricity, and cutting accuracy.
• Versatile Applications: Suitable for plywood, composites, and a variety of natural woods.

Applications

The CMT Straight Bit Long Series is designed for general-purpose straight routing and demanding woodworking applications. Use it for creating grooves and dados, removing stock, routing recesses, producing straight-sided profiles, and other applications requiring a clean and accurate cut. Its long-series configuration is particularly useful when additional cutting depth is needed.

Safety Tips

Dust and chips produced when routing laminate and composite materials can be hazardous to your health and safety. Always wear appropriate eye protection and a properly rated dust mask or respirator when routing. Use suitable dust collection whenever possible to help minimize airborne particles.

Safety Precautions

• Never use a router bit that is damaged, cracked, worn, or otherwise compromised.
• Always install the bit securely and make sure it is properly seated in the router collet.
• Operate the router at the recommended speed and feed rate for the bit and material being cut.
• Do not force the router bit through the workpiece. Allow the cutter to remove material at an appropriate rate.
• When removing a substantial amount of material, use multiple passes rather than attempting to make one excessively deep cut.
• Take particular care when making the initial cut, especially when working with smaller diameter router bits.
• Keep hands, clothing, and other objects away from the rotating cutter.

How CMT Produces High-Quality Router Bits

• Turning, Milling and Cutting: CMT has made significant investments in modernizing its manufacturing operations. Automated production equipment and CNC machinery operated by specially trained personnel help ensure that router bit shanks and bodies are manufactured with exceptional accuracy and balance.
• Heat-Forged Steel Bodies for Large-Diameter Bits: Certain router bits require additional manufacturing steps to provide the strength and durability needed for demanding applications. Larger-diameter bits can undergo a heat-forging process before the steel is turned into a precision bit body. This process creates a radial grain orientation that provides increased strength and durability.
• Precision Brazing: CMT has pioneered advanced brazing techniques for router bit production. Custom-designed computerized brazing equipment helps reduce inconsistencies associated with traditional hand brazing. CMT’s silver-copper-silver brazing construction provides a strong, reliable bond between the carbide cutters and steel body, helping the cutting edges remain secure during demanding use.
• Micrograin Carbide: High-quality micrograin carbide is used to produce sharp, durable cutting edges. The carbide construction provides the wear resistance needed for extended production while maintaining precise cutting performance.
• Quality Control: Each CMT router bit undergoes strict quality testing to verify cutting tolerance, balance, and concentricity. These controls help ensure consistent performance from bit to bit and contribute to the clean, precise results expected from CMT tooling.
• Orange PTFE Non-Stick Coating: The distinctive orange PTFE coating helps protect the bit surface and minimize the accumulation of resin, pitch, and other materials generated during routing. This helps maintain efficient cutting performance and simplifies cleanup.
