SHARPRO 1/16 Downcut Router Bit – 1/4in Shank, Spiral Coated Carbide End Mill

Unlock precise woodworking with SHARPRO

The SHARPRO 1/16 Downcut Router Bit is engineered for wood enthusiasts and professionals who demand clean, consistent results every pass. With a 1/4 in shank and a 2 in overall length, this coated carbide bit is built to withstand fast CNC workflows while delivering reliable edge quality across softwood, hardwood, MDF, plywood, laminate, and composite boards.

Key design choices support clean finishes and reduced tear-out. The bit features a 140-degree included angle on the end cutting edge, which promotes rapid chip evacuation and helps resist upward thrust during high-speed cutting. The down-cut spiral directs chips downward, contributing to a smoother top surface and fewer burrs.

• Premium carbide edge stays sharp after repeated use for fast, precise cuts
• Ra surface roughness below 0.8 μm keeps workpiece surfaces smooth
• 140-degree end-cutting angle promotes rapid chip evacuation
• Down-cut spiral directs chips downward to minimize tear-out
• Versatile across softwood, hardwood, MDF, plywood, laminate, and more

This solid carbide bit excels at slotting, mortising, engraving, and carving on a range of materials and projects. It is well-suited for woodcraft, signage, cabinetry details, and decorative inlays, while also handling light-duty engraving on acrylic or aluminum. The coating adds durability for repeated passes in busy shop settings.

• Slotting and mortising for precise joinery and cabinetry
• Engraving and carving on wood and composite materials
• Light-duty engraving on acrylic or aluminum

Quality and reliability are baked into every SHARPRO bit. A secure plastic case with a compression holder and rubber cap protects the flutes during transport and storage, while serialized tracking and a tight +0.02 mm tolerance support consistent performance in professional workflows. For best results, pair with a suitable CNC setup and maintain steady feeds to maximize the bit’s efficiency and longevity.
