Onsrud 66-942ALTIN Diamond Pattern Router Bit Solid Carbide

Product Description

The ONSRUD 66-942ALTIN is a diamond pattern router bit designed for high-performance material removal in composite machining applications. Built from solid carbide with an AlTiN coating, this bit delivers extended tool life and resistance to heat buildup at the cutting edge. It features a 0.5 inch cutter diameter, a 2.125 inch length of cut, and a 4 inch overall length. The burr end type and right-hand cutting direction make it well suited for aggressive stock removal and surface finishing in composite materials. This tool is intended for use in CNC machine setups operated by experienced machinists and CNC programmers.

The 66-942ALTIN is built for composite material applications, including fiberglass, carbon fiber, and similar laminates commonly encountered in aerospace, marine, and industrial fabrication environments. It mounts via a 0.5 inch shank diameter with a 1.875 inch shank length, fitting standard CNC router collet systems. The diamond pattern geometry promotes chip evacuation and reduces delamination risk in layered composite workpieces. This bit is appropriate for production CNC routing where consistent edge quality and tool durability are required across repeated passes.

Key Features

• AlTiN coating provides thermal protection and extends cutting life in high-speed applications
• Diamond pattern burr geometry supports aggressive material removal with reduced delamination
• Right-hand cutting direction compatible with standard CNC router spindle configurations
• 0.5 inch shank diameter fits common CNC collet sizes
• Part of the ONSRUD 66-900 series, designed specifically for composite material routing

Compatibility

Designed for use in CNC machines with a compatible 0.5 inch collet or toolholder. Intended for composite material applications as noted in the ONSRUD 66-900 series product line.

Installation Notes

Installation and tool changes should be performed by qualified CNC machine operators with the spindle fully powered down and the machine in a safe, locked-out state. Ensure the collet and toolholder are clean and free of debris before seating the shank. Do not exceed the manufacturer-recommended spindle speed range for the material being cut. Follow applicable shop safety standards and machine manufacturer guidelines when programming feeds and speeds for composite routing operations.
