CMT Solid Carbide Down Spiral Bit - 3/16" is a precision downcut spiral router bit engineered for woodworking and fabrication tasks where a clean, tearout-free surface on the top face is the priority. Built entirely from a special super-micrograin carbide formulation, this 3/16" downcut spiral bit delivers a keen, long-lasting cutting edge suited for solid wood, wood composites, plastic materials, and laminates. The low-angle spiral geometry shears material cleanly while ejecting chips efficiently, keeping the tool running cooler and extending edge life - making it a reliable choice for CNC routing machines, router tables, and handheld routers alike.

Key Features

• Super-Micrograin Solid Carbide Construction - a special super-micrograin carbide formulation produces and holds a keen cutting edge longer than standard carbide, meaning fewer tool changes and consistently cleaner cuts across extended production runs.
• Downcut Spiral Geometry - presses chips downward into the cut rather than upward, preventing tearout on the upper surface and delivering a smooth, finished face - ideal when upper-face quality is critical, such as veneer, laminate, and finished panel work.
• Low-Angle Spiral Design - specifically engineered to shear wood cleanly and provide efficient chip ejection, so the bit runs cooler during operation and the cutting edges last longer between resharpenings.
• 2-Flute Configuration - two cutting teeth balance chip load and feed rate, giving you smooth cutting performance across solid hardwoods, softwoods, plywood, MDF, plastics, and laminates.
• 1/4" Shank - fits standard 1/4" collets on a wide range of handheld routers, router tables, and CNC routing machines, making this bit highly versatile across setups.
• Right-Hand Rotation - compatible with the vast majority of routing equipment, ensuring straightforward drop-in use without specialized toolholding requirements.
• 3/4" Cutting Height with 2" Total Length - the 3/4" depth of cut handles a practical range of material thicknesses, while the compact 2" overall length provides stability and reduces vibration during use.

Why This Product

• When upper-face finish quality cannot be compromised - such as routing veneered panels, laminates, or melamine - the downcut spiral geometry actively prevents tearout by pushing fibers downward rather than lifting them.
• The super-micrograin carbide formulation holds a sharper edge longer and withstands the heat generated during routing of dense or abrasive materials like hardwood composites and plastics, reducing downtime for tool changes.
• At 3/16" diameter, this bit is well suited for narrow slots, detail work, and tight-radius cuts that larger bits cannot reach, expanding the range of precision work possible on CNC machines and handheld routers.
• The low-angle spiral and efficient chip ejection keep operating temperatures lower, which directly protects both the cutting edge and the workpiece surface - a practical advantage when working with heat-sensitive materials such as plastics and laminates.
