Onsrud 66-923ALTIN Diamond Pattern Router Bit Altin

Product Description

The ONSRUD 66-923ALTIN is a diamond pattern router bit designed for high-performance cutting of composite materials on CNC machines. Built from solid carbide, it features an AlTiN (Aluminum Titanium Nitride) coating that improves heat resistance and extends tool life in demanding routing applications. The 0.375-inch cutter diameter pairs with a 1-inch length of cut and a 3-inch overall length, making this bit well suited for precision profiling and trimming passes. Right-hand cutting geometry is standard. Licensed HVAC and trade professionals working in fabrication environments rely on bits like this for consistent, clean results on composite panels and similar engineered materials.

This router bit is intended for use in CNC machine applications where composite material routing is required. The diamond pattern geometry helps manage chip evacuation and reduces heat buildup at the cutting zone. With a 3/8-inch shank diameter and a 2-inch shank length, it mounts securely in standard collet systems used on production and job-shop CNC routers. It is appropriate for both production-run and custom-fabrication environments where composite cutting is a regular task.

Key Features

• Solid carbide construction provides rigidity and wear resistance in composite routing
• AlTiN coating improves thermal resistance and extends cutting tool life
• Diamond pattern geometry promotes chip evacuation and reduces heat at the cut
• Right-hand cutting direction compatible with standard CNC spindle rotation
• 3/8-inch shank diameter fits common CNC router collet sizes
• Part of the ONSRUD 66-900 series for composite material applications

Compatibility

Designed for use in CNC machines with a standard 3/8-inch collet; rated for composite material applications as part of the ONSRUD 66-900 series.

Installation Notes

Installation should be performed by a qualified CNC machinist or tooling technician. Power down and lock out the CNC spindle before changing tooling. Seat the shank fully into the collet to the manufacturer-specified engagement depth and torque the collet nut using the appropriate collet wrench. Inspect the bit for chipping or coating wear before each use; do not operate a damaged bit.
