Onsrud 66-910ALTIN Diamond Pattern Router Bit Solid Carbide

Product Description

The ONSRUD 66-910ALTIN is a diamond pattern router bit designed for precision cutting in composite materials on CNC machines. Built from solid carbide with an AlTiN (aluminum titanium nitride) coating, this burr-style end tool delivers hardness and heat resistance needed for demanding composite routing applications. It features a 0.25 inch cutter diameter, a 1 inch length of cut, and a 3 inch overall length, making it well suited for detailed profiling and material removal in tight geometries. The right-hand cutting direction is standard for conventional CNC spindle rotation.

This bit is engineered for composite material applications, including fiber-reinforced panels and laminate structures commonly encountered in aerospace, industrial fabrication, and manufacturing environments. CNC machine operators and tooling technicians working with abrasive composite stacks will find the diamond pattern geometry and AlTiN finish effective for extending tool life compared to uncoated carbide. It mounts via a 1/4 inch shank with a 2 inch shank length, compatible with standard CNC collet systems.

Key Features

• Solid carbide construction for rigidity and wear resistance in abrasive composites
• AlTiN coating increases surface hardness and thermal resistance at the cutting edge
• Diamond pattern burr geometry promotes efficient chip evacuation in composite materials
• Right-hand cutting direction for standard CNC spindle operation
• 1/4 inch shank fits common CNC collet sizes without adapter
• Part of the ONSRUD 66-900 series, designed specifically for composite routing

Compatibility

Designed for use in CNC machines with 1/4 inch collets; intended for composite material applications as part of the ONSRUD 66-900 series.

Installation Notes

Installation should be performed by a qualified CNC machine operator or tooling technician. Ensure the CNC machine is fully powered down and the spindle has come to a complete stop before changing tooling. Seat the 1/4 inch shank fully into the collet and torque the collet nut according to the machine manufacturer specifications. Inspect the cutting edges for chipping or coating wear before each use, as damaged carbide tooling can compromise cut quality and workpiece integrity.
