Grinding/Carbide Burr EXO FREZ HARD BLUE STOŻEK 07 by EXO

EXO FREZ HARD BLUE STOŻEK 07 is a conical carbide burr designed for controlled material removal, deburring and precise contouring. The tool’s conical profile allows access to angled surfaces and tight areas, making it suitable for shaping and finishing work on hard materials. Manufactured by EXO, this burr is intended for applications that require a hard-cutting geometry and stable performance during intermittent or continuous use.

Advantages

The conical shape provides improved access to angled and recessed surfaces while maintaining precise control over the cut. Tungsten carbide construction offers high hardness and wear resistance for extended tool life on hard materials. The HARD BLUE coating contributes to reduced friction and improved heat resistance during aggressive cutting. The burr's cutting geometry is optimized for efficient material removal with predictable chip flow and minimized vibration.

Suitable for

• Deburring and edge finishing on steel and hard alloys
• Shaping and contouring in toolroom operations
• Removing weld spatter and flash in tight or angled areas
• Preparatory grinding before welding or surface treatment

Key specifications

• Tool profile: conical (stożek) for angled surface access
• Material: solid tungsten carbide for high hardness
• Coating: HARD BLUE surface treatment for reduced friction
• Typical use: material removal, deburring, shaping and finishing

How to use

Secure the burr in a compatible rotary tool or die grinder with the correct collet size and ensure firm clamping to prevent runout. Operate at manufacturer-recommended speeds for carbide burrs and apply light, steady pressure—avoid forcing the tool to prevent premature wear. Use appropriate coolant or intermittent cutting to manage heat when working on high-strength alloys. Allow the burr to perform multiple light passes rather than aggressive single passes for a controlled finish.

Usage recommendations

Wear appropriate personal protective equipment such as eye protection, gloves and ear protection. Match rotational speed and feed to the work material, inspect the burr regularly for wear, and replace when cutting performance degrades to maintain surface quality and safety.
