Onsrud 66-951ALTIN Diamond Pattern Router Bit Altin

Product Description

The ONSRUD 66-951ALTIN is a solid carbide diamond pattern router bit designed for high-performance cutting in composite materials on CNC machines. With a 0.5-inch cutter diameter and a 4.125-inch length of cut, this end mill geometry provides aggressive material removal while managing heat and chip load in demanding composite routing applications. The AlTiN (aluminum titanium nitride) coating extends tool life by reducing friction and improving thermal resistance at the cutting edge. Overall length is 6 inches with a 1/2-inch shank diameter, making it compatible with standard CNC router collets used in production environments.

This bit is engineered for use in composite material applications, including fiber-reinforced panels and similar laminated or layered sheet goods. The diamond pattern flute geometry helps evacuate chips efficiently and reduces delamination risk along cut edges. It is suited for CNC routing operations in production shops, aerospace fabrication, sign manufacturing, and similar trades where clean, consistent composite cuts are required. Right-hand cutting direction is standard for conventional CNC spindle setups.

Key Features

• Solid carbide construction for rigidity and wear resistance in abrasive composite materials
• AlTiN coating reduces friction and extends tool life under high-speed cutting conditions
• Diamond pattern flute geometry promotes clean cuts and efficient chip evacuation in composites
• 4.125-inch length of cut allows routing through thick composite panels in a single pass
• Right-hand cutting direction compatible with standard CNC router spindle rotation
• 1/2-inch shank diameter fits common CNC collet systems without adapters

Compatibility

Designed for use with CNC machines equipped with 1/2-inch collets. Intended for composite material applications as specified by the manufacturer for the 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 fully into the collet to the recommended engagement depth and torque the collet nut per the machine manufacturer specifications. Verify spindle speed and feed rate settings are appropriate for composite material before initiating a cut.
