Onsrud 66-926ALTIN Diamond Pattern Router Bit Altin

Product Description

The ONSRUD 66-926ALTIN is a solid carbide diamond pattern router bit designed for high-performance material removal in CNC machining applications. With a 0.375 inch cutter diameter and a 1.625 inch length of cut, this burr-style bit delivers aggressive stock removal with controlled chip evacuation. The AlTiN (Aluminum Titanium Nitride) coating increases surface hardness and heat resistance, extending tool life in demanding cutting cycles. At 3.5 inches overall length with a 0.375 inch shank diameter, the 66-926ALTIN fits standard CNC router collet systems and is built to handle composite materials in production environments.

This router bit is intended for use on CNC machines cutting composite materials, including fiber-reinforced panels, laminates, and similar engineered substrates. The diamond pattern geometry is well suited to trimming, profiling, and finishing operations where burr-style cutting action is required. Right-hand cutting direction makes it compatible with standard CNC spindle rotation. The 1.875 inch shank length provides secure tool holding at typical CNC collet depths, reducing deflection during continuous cuts.

Key Features

• Diamond pattern burr geometry promotes efficient chip clearing and smooth surface finish
• Right-hand cutting direction compatible with standard CNC router spindles
• 0.375 inch shank diameter fits common CNC collet sizes
• Part of the ONSRUD 66-900 series, designed for composite material applications

Compatibility

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

Installation Notes

Installation should be performed by a qualified CNC operator or tooling technician. Power down and lock out the CNC spindle before changing tooling. Insert the shank to the full recommended depth in the collet and torque the collet nut according to the machine manufacturer's specifications. Inspect the cutting edges for wear or chipping before each use and replace the bit when cutting performance degrades.
