Onsrud 67-017 Abrasive Cylinder Bur Solid Carbide

Product Description

The ONSRUD 67-017 is a solid carbide abrasive cylinder bur designed for material removal and surface finishing in demanding fabrication applications. It features a cylinder head shape with a flat end type and a double cut tooth style, making it effective for aggressive stock removal and controlled finishing in a single tool. The 0.25 inch cutter diameter matches the 0.25 inch shank diameter, allowing direct chuck mounting without a reducer. A diamond coating enhances cutting edge durability when working abrasive materials. This bur is suited for use by machinists, composites fabricators, and trade professionals who require precise rotary filing performance.

The ONSRUD 67-017 is engineered specifically for composite and fiberglass material applications. These substrates are highly abrasive and quickly degrade standard high-speed steel tooling, making solid carbide construction with a diamond coating the preferred choice. Typical use cases include trimming, deburring, slotting, and edge cleanup on composite panels, fiberglass components, and similar laminate structures found in aerospace fabrication, marine construction, and industrial manufacturing environments.

Key Features

• Solid carbide construction provides superior wear resistance in abrasive composite and fiberglass materials
• Diamond coating extends cutting edge life under high-friction cutting conditions
• Double cut tooth style enables efficient material removal with a smoother finish than single cut
• Cylinder head shape with flat end suits straight-wall profiling, slotting, and surface grinding tasks
• 0.25 inch shank diameter fits standard 1/4 inch collets and rotary tool chucks

Compatibility

Designed for use in composite and fiberglass material applications. Fits standard 1/4 inch collets on die grinders, CNC routers, and rotary tools. Consult tool manufacturer specifications to confirm collet and speed compatibility before use.

Installation Notes

Installation and use of rotary burs should be performed by qualified machinists or fabricators familiar with rotary cutting tool safety. Ensure the spindle is fully powered down and the tool holder is depressurized or de-energized before mounting or removing the bur. Confirm the collet is properly sized for the 0.25 inch shank and fully tightened before operation. Always operate within the maximum RPM rating of the tool and wear appropriate PPE including eye protection when working with abrasive materials.
