CMT Straight Bit Long Series - 1/2 in. Diameter, 1/2 in. Shank by CMT is engineered for woodworkers and CNC operators who need to make deep, precise cuts in a single pass. With a 2 in. cutting height and 4-1/4 in. total length, this long-series straight router bit reaches depths that standard-length bits simply cannot, making it an excellent choice for deep dadoes, grooves, panel joinery, and template routing. The right-hand rotation, 2-flute micrograin carbide construction delivers smooth, clean edges every time - whether you are working on a handheld router, a router table, or a CNC routing machine.

Key Features

• Long-Series 2 in. Cutting Height - reaches deep into the workpiece in a single setup, eliminating the need for multiple passes and reducing setup time on deep dadoes and grooves.
• Micrograin Carbide Cutters on Special Fatigue Proof Steel - the combination of high-density micrograin carbide and fatigue-resistant steel bodies allows these double-faced cutters to handle heavy workloads while still producing a smooth, precise cut edge every time.
• CMT Orange Shield Non-Stick PTFE Coating - the trademark orange surface treatment prevents resin, pitch, and other residue from adhering to the bit, reducing heat buildup, protecting against corrosion, and extending overall tool life.
• Exceptional Chip Ejection Design - aggressive flute geometry clears chips away from the cut zone rapidly, resulting in cleaner, more consistent cutting performance and cooler operation during extended runs.
• 2-Flute (2-Tooth) Configuration - twin cutting edges provide a balanced cut with good surface quality, suitable for solid hardwoods, softwoods, plywood, MDF, chipboard, laminates, melamine, and plastics.
• Right-Hand Rotation - matches the standard rotation direction of virtually all handheld routers, router tables, and CNC routing spindles for straightforward, no-compromise compatibility.
• 1/2 in. Shank Diameter - the larger shank provides greater rigidity and reduced vibration compared to 1/4 in. shank bits, translating to better cut accuracy and a finer finished surface, especially important at the extended reach of a long-series bit.

Why This Product

• The 2 in. cutting height on a 4-1/4 in. long-series body solves the specific challenge of routing deep mortises, full-depth panel dadoes, and thick-stock grooves that standard-length straight bits cannot reach without repositioning.
• The micrograin carbide construction paired with fatigue-proof steel is built to sustain heavy, repeated cuts - making this bit a practical choice for production environments and demanding shop work rather than light occasional use.
• CMT's PTFE orange coating actively reduces resin and pitch adhesion, which means less frequent cleaning, less heat-related dulling, and a longer useful life per bit - a measurable advantage when routing resinous woods, laminates, or melamine.
• The 1/2 in. shank combined with exceptional chip ejection geometry keeps the bit stable and cool during long, deep cuts, reducing the risk of tear-out or burning on finished workpiece edges.
