CMT Straight Bit Long Series - 1/2" Diameter, 1/4" Shank is a professional-grade routing tool engineered for deep, precise cuts in a wide range of wood and composite materials. Built with micrograin carbide cutters and protected by CMT's trademark orange non-stick PTFE coating, this long-series straight router bit delivers clean, smooth results whether you are cutting dadoes, grooves, or deep straight profiles in solid hardwood, plywood, MDF, or laminates. The extended cutting height makes it especially well-suited for applications where a standard-length straight bit simply cannot reach.

Key Features

• Micrograin Carbide Cutters on Special Fatigue Proof Steel - the combination of high-density carbide tips and fatigue-resistant steel bodies means these cutters handle heavy routing loads without deflecting or dulling prematurely, so you get a consistently precise edge from the first pass to the last.
• Double-Faced Cutters with 2 Cutting Teeth - dual cutting edges work simultaneously to produce a beautiful, clean finish on both faces of the cut, reducing the need for sanding or secondary cleanup operations.
• Orange Non-Stick PTFE Surface Coating - CMT's proprietary coating resists resin, pitch, and other residue buildup that causes heat and friction, helping the bit stay cleaner, run cooler, and last longer between sharpenings.
• Exceptional Chip Ejection - the bit geometry is designed to evacuate chips rapidly and consistently, resulting in cleaner cutting action and reduced re-cutting of waste material that would otherwise degrade surface quality.
• Long Series Cutting Height of 1 1/4" - the extended reach allows deeper grooves, dadoes, and mortises in a single pass compared to standard-length bits, reducing setup time and improving workflow efficiency.
• Right-Hand Rotation - compatible with all standard handheld routers, router tables, and CNC routing machines, allowing straightforward drop-in use without special toolholder requirements.

Why This Product

• The 1 1/4" cutting height in a long-series format solves the problem of shallow-reach standard bits when working on deep dadoes, thick panel grooves, or template routing tasks where full depth is essential in one controlled pass.
• The PTFE non-stick coating directly reduces resin and pitch adhesion - one of the most common causes of bit overheating and premature wear - making this bit a practical choice for production environments and repetitive cutting in hardwoods, melamine, and plastics.
• With a 1/4" shank and right-hand rotation, this bit fits a broad range of compact and full-size routers, making it a versatile addition to a shop toolkit without requiring dedicated machinery.
• Micrograin carbide paired with fatigue-proof steel means the bit maintains its edge under continuous heavy-duty use, which translates to fewer tool changes, less downtime, and consistently smooth finished surfaces across solid hardwood, MDF, chipboard, and laminates.
