Onsrud 66-930ALTIN Diamond Pattern Router Bit Solid Carbide

Product Description

The ONSRUD 66-930ALTIN is a solid carbide diamond pattern router bit designed for precision material removal in CNC machining applications. It features an AlTiN (Aluminum Titanium Nitride) coating that increases surface hardness and thermal resistance, extending tool life under high-feed cutting conditions. The bit measures 0.375 inches in cutter diameter with a 2.125-inch length of cut and a 4-inch overall length. The burr-style end geometry and diamond pattern flute profile are engineered to produce a controlled cutting action suited to composite materials. This tool is installed and operated by CNC machinists and composite fabrication technicians.

This router bit is specified for composite material applications and runs in CNC machine spindles with a 3/8-inch collet. The right-hand cutting direction suits standard CNC router setups. With a 1.875-inch shank length and 3/8-inch shank diameter, it fits standard ER collet systems commonly found on CNC routers used in aerospace, signage, and industrial composite fabrication environments. Refer to the Series 66-900 family for related tooling configurations from ONSRUD.

Compatibility

Designed for use in CNC machines with a 3/8-inch collet. Intended for composite material applications. Part of the ONSRUD 66-900 series.

Installation Notes

Installation should be performed by a qualified CNC machinist. Power down and de-energize the CNC machine spindle completely before installing or removing tooling. Seat the shank fully in the collet to the manufacturer-recommended engagement depth and torque the collet nut according to the collet system specifications. Verify spindle speed and feed rate settings are appropriate for the material and tool diameter before initiating a cut.
