Onsrud 67-428 Abrasive Cylinder Bur Solid Carbide

Product Description

The ONSRUD 67-428 is a solid carbide abrasive cylinder bur designed for controlled material removal in demanding routing and finishing applications. The flat end type and cylindrical profile allow the tool to work along surfaces and into confined areas with consistent contact. With a 0.25-inch cutter diameter and a 0.25-inch shank diameter, the 67-428 mounts directly into standard quarter-inch collets without an adapter. Solid carbide construction provides the rigidity and wear resistance required when working composite panel materials at high feed rates and spindle speeds.

This bur is suited for use on composite panels in both production and fabrication environments. Typical applications include edge finishing, surface blending, and material removal on laminate or composite sheet goods. It is a common choice for CNC router operators and skilled fabricators who require precise, repeatable results on engineered panel products. The 0.25-inch shank fits the collet configurations found on most CNC routing platforms and handheld die grinder setups used in shop and field work.

Key Features

• Solid carbide body for extended tool life and resistance to deflection under load
• Cylinder profile with flat end type for surface-parallel cutting and edge work
• 0.25-inch cutter diameter matches standard quarter-inch collet systems
• Optimized for composite panel material applications
• Lightweight at 0.07 pounds for reduced spindle load

Compatibility

Designed for use with composite panels and compatible with routing equipment and die grinders that accept a 0.25-inch shank collet.

Installation Notes

Installation is performed by machinists, CNC operators, or fabricators familiar with rotary cutting tools. Power down and de-energize the spindle or tool fully before changing burs. Seat the shank fully into the collet and tighten to the equipment manufacturer's specified torque range before operation. Inspect the bur for chipping or wear before each use and do not operate a damaged tool.
