CMT Solid Carbide Straight Bit - Long Series, 1/4 in. Diameter, 1/4 in. Shank by CMT is engineered for woodworkers who need to reach deeper into their workpiece with precision and confidence. With a 1 in. cutting height and a micrograin carbide construction, this long-series straight router bit delivers smooth, clean edges on dadoes, grooves, and inlay work where standard-length bits simply cannot reach. Whether you are running it through a handheld router, a router table, or a CNC routing machine, the razor-sharp double-faced cutters and right-hand rotation handle even the heaviest cutting loads while maintaining a precise, consistent profile pass after pass.

Key Features

• Solid Micrograin Carbide Construction - the full carbide body resists wear and heat buildup during demanding cuts in hardwood, MDF, plywood, laminates, and plastics, so the bit stays sharp and true through extended use.
• Long Series Design with 1 in. Cutting Height - reaches deeper into the workpiece than standard-series bits, making it the right choice for full-depth dadoes, deep grooves, and template routing tasks that shorter bits cannot complete in a single pass.
• Double-Faced Razor-Sharp Cutters - both cutting faces are made from special Fatigue Proof steel and micrograin carbide, meaning the bit can withstand heavy workloads while still producing a smooth, precise cut every time.
• Exceptional Chip Ejection - the flute geometry actively clears waste material away from the cut, allowing cleaner and more constant cutting without clogging or burning, even in deep-pass operations.
• CMT Orange Non-Stick PTFE Coating - the trademark orange surface treatment prevents resin, pitch, and other residue from sticking to the bit body, reducing heat and friction while protecting against corrosion and extending tool life.
• 2-Flute Geometry, Right-Hand Rotation - two cutting edges balance feed rate and chip clearance, giving you a smooth, controlled cut whether you are routing freehand or feeding material across a router table.

Why This Product

• The 1 in. cutting height combined with the solid carbide long-series body lets you cut full-depth dadoes and grooves in a single pass - eliminating the multiple shallow passes required by shorter bits and reducing total setup time.
• Micrograin carbide and Fatigue Proof steel construction mean the bit holds its edge under heavy workloads, making it a dependable choice for production environments and repetitive routing tasks where consistent results matter.
• The PTFE non-stick coating actively repels resin and pitch during cuts in MDF, laminates, melamine, and natural woods, keeping the bit cleaner between uses and reducing the frequency of cleaning stops during a project.
• The 1/4 in. shank fits the widest variety of handheld routers, router tables, and CNC routing machines, so this bit integrates into your existing setup without adapters or special collets.
