Onsrud 66-946ALTIN Diamond Pattern Router Bit Solid Carbide

Product Description

The ONSRUD 66-946ALTIN is a diamond pattern router bit engineered for high-performance CNC machining applications. Built from solid carbide and finished with an AlTiN coating, it delivers excellent hardness and heat resistance during continuous cutting operations. The bit features a 0.5 inch cutter diameter and a 3.125 inch length of cut, making it well suited for deep profiling and surfacing passes. The burr-style end type produces an aggressive cutting action with a right-hand cutting direction. Licensed HVAC techs, plumbers, electricians, and pool service professionals who fabricate composite panels or enclosures rely on solid carbide tooling like this for consistent, repeatable results on CNC equipment.

This router bit is designed for use on CNC machines cutting composite materials. The 1/2 inch shank diameter fits standard collets on most industrial and production CNC routers. With a 1.875 inch shank length and a 5 inch overall length, the tool has the reach required for thicker composite workpieces and nested fixture setups. The AlTiN finish extends tool life when running at elevated spindle speeds common in production environments. Trade professionals machining composite panels, ductwork access doors, or equipment enclosures will find this geometry appropriate for clean, burr-minimizing cuts through layered composite substrates.

Key Features

• Solid carbide construction provides rigidity and wear resistance in demanding CNC applications
• AlTiN coating improves heat resistance and extends tool life at high spindle speeds
• Diamond pattern burr geometry delivers aggressive material removal on composite substrates
• 0.5 inch cutter diameter and 3.125 inch length of cut suit deep profiling passes
• Right-hand cutting direction compatible with standard CNC router spindle rotation
• 1/2 inch shank diameter fits standard collets on most production CNC routers

Compatibility

Designed for use with CNC machines equipped with a 1/2 inch collet. Rated for composite material applications per manufacturer specifications in the 66-900 series.

Installation Notes

Installation and tool changes should be performed by a qualified CNC machine operator with the spindle fully stopped and the machine in an e-stop or locked-out state. Verify collet condition and ensure the shank is fully seated and properly torqued before running. Inspect the tool for chips or cracks before each use, as solid carbide can fracture if run in a damaged collet or at incorrect feed and speed parameters. Follow the machine and tooling manufacturer guidelines for composite cutting parameters.
