Onsrud 60-113MC Compression Spiral Router Bit Solid Carbide

Product Description

The ONSRUD 60-113MC is a solid carbide compression double edge spiral router bit designed for CNC routing applications requiring clean cuts on both the top and bottom surfaces of the workpiece. The compression flute geometry combines an upcut and downcut spiral in a single tool, directing cutting forces inward to minimize tearout and delamination on veneered panels, laminates, and composite sheet goods. This bit uses a right-hand cutting direction and is not piloted, making it suited for through-cuts and profile routing on CNC machines. Machinists and fabricators working with finished panel products rely on this geometry to eliminate secondary sanding or edge cleanup.

The 60-113MC is intended for use in CNC router applications processing double-sided laminated panels, melamine, MDF with veneer faces, plywood, and similar composite sheet materials where surface quality on both the entry and exit face is critical. It is installed without a pilot bearing, so toolpaths are controlled entirely by the CNC program. This bit is appropriate for production shops, millwork operations, and sign fabricators running high-volume panel processing.

Key Features

• Compression flute geometry reduces tearout on top and bottom workpiece faces simultaneously
• Solid carbide construction provides hardness and wear resistance for abrasive composite materials
• Double edge design increases feed rate capability and chip load per tooth
• Right-hand cutting direction compatible with standard CNC router spindle rotation
• Non-piloted configuration for full CNC toolpath control without a bearing guide

Compatibility

Designed as an OEM-style replacement or direct-use solid carbide compression spiral router bit for CNC routers accepting the corresponding shank diameter and collet size.

Installation Notes

Installation should be performed by a qualified CNC machinist or tooling technician with the spindle fully powered down and locked out per machine-specific lockout/tagout procedures. Insert the shank to the full recommended collet depth and torque the collet nut according to the machine manufacturer specification. Inspect the cutting edges for chips or damage before each use, as carbide is brittle and a damaged edge can fracture during operation. Always verify spindle RPM and feed rate against the manufacturer cutting data for the specific material being processed.
