EXO cutting burr EXO FREZ HARD BLUE conical straight 03

EXO FREZ HARD BLUE conical straight 03 is a cutting burr designed for processing metal and other hard materials. It has a hardened cutting surface and a conical straight profile that enables precise removal of material, edge finishing and shaping of cavities. The tool is intended for use with rotary tools and die grinders where consistent cutting performance and dimensional control are required.

Advantages

The hardened cutting surface provides extended wear resistance and sustained cutting performance on tough materials. The conical straight geometry offers access to tight spaces and allows controlled material removal along tapered surfaces. The tool is suitable for multiple operations including filing, deburring and fine shaping, delivering repeatable results when used at recommended speeds and with appropriate tool holders.

Suitable for

• Deburring edges and removing burrs from machined parts
• Filing and shaping metal workpieces in confined or tapered areas
• Creating or enlarging cavities and grooves
• Surface preparation prior to welding or coating
• Detail work on steel, stainless steel and other hard materials

Key specifications

• Shape: conical straight profile (model 03)
• Material surface: hardened cutting surface for increased wear resistance
• Intended materials: metal and other hard materials
• Tool compatibility: rotary tools and die grinders
• Primary operations: filing, deburring, shaping, cavity work

How to use

Secure the cutting burr in the collet or chuck of a rotary tool or die grinder according to the tool manufacturer's instructions. Operate at speeds appropriate for the material being worked—start at moderate speed and adjust as needed to maintain control and avoid overheating. Apply light, consistent pressure and use steady strokes to remove small amounts of material; avoid forcing the burr to prevent premature wear. When working in confined spaces or on detailed features, choose appropriate approach angles to maintain visibility and control.

Usage recommendations

Wear appropriate personal protective equipment including eye protection, gloves and hearing protection. Use cutting fluid or intermittent contact when machining stainless steel or other heat-sensitive alloys to reduce heat buildup. Inspect the burr regularly for signs of wear or damage and replace when cutting efficiency decreases to maintain consistent results.
