Onsrud 63-712 Spiral Upcut Router Bit 1/8 in Solid Carbide

Product Description

The ONSRUD 63-712 is a solid carbide spiral upcut router bit designed for cutting hard materials including acrylic, nylon, PVC, polycarbonate, and solid surfaces. With a 0.125-inch cutter diameter, a 0.5-inch length of cut, and a 21-degree helix angle, it delivers clean chip evacuation and precise cutting geometry in demanding CNC and handheld routing applications. The single-edge, right-hand cutting configuration suits situations where upward chip pull and reduced heat buildup are priorities. Machinists and CNC operators working in plastics fabrication and composites shops rely on this size and style for detail routing and slot work.

The 63-712 is suited for residential and commercial fabrication environments where hard thermoplastics and engineered solid surfaces are processed. Typical applications include routing acrylic sheet, nylon stock, PVC profiles, and polycarbonate panels. The 0.125-inch diameter makes it well suited for narrow slot cutting, edge finishing, and detail profiling passes on CNC routers. The 1/4-inch shank diameter fits standard collet systems on most production and benchtop CNC routers.

Key Features

• Solid carbide construction for extended tool life in hard plastic and engineered material applications
• Upcut flute geometry pulls chips away from the workpiece and reduces heat accumulation at the cut
• 21-degree helix angle optimized for clean edge quality in acrylic, nylon, PVC, and polycarbonate
• Single-edge router style for precise material removal in narrow-kerf applications
• Uncoated finish - no coating interference when working with materials sensitive to contamination
• Right-hand cutting direction compatible with standard CNC router spindle rotation

Compatibility

Compatible with material applications including acrylic, nylon, PVC, polycarbonate, and solid surfaces. Fits 1/4-inch collet systems. Part of the ONSRUD 63-700 series of spiral router bits for hard materials.

Installation Notes

Installation is performed by CNC machinists or tooling technicians. Power down and de-energize the spindle completely before inserting or removing the bit from the collet. Secure the shank fully into the collet to the recommended engagement depth before tightening - never leave less than two-thirds of the shank length engaged. Inspect the cutting edge for chips or wear before each use, as carbide tooling in hard materials is subject to edge micro-fracture if run at incorrect feeds and speeds.
