Rotary burr GRAPHITE 55H366 — single-piece metalworking cutting tool, 36 g

GRAPHITE 55H366 rotary burr is a single-piece metalworking cutting tool weighing 36 g, engineered for shaping, deburring and controlled material removal on metal, aluminum, wood and plastics. The tool features an oval (type E) head profile with cemented carbide construction for high hardness and abrasive wear resistance. It is intended for use in rotary tools and straight grinders where medium spindle speeds are applied, and its geometry supports precision edge finishing and surface preparation in repair, fabrication and hobby projects.

Advantages

The solid carbide body provides long service life and consistent cutting performance under heavy use. Double-notched flutes promote efficient chip evacuation and produce smaller chips that reduce load on the cutting edges. Precise oval geometry enables controlled profiling and finishing of contours, while the single-piece construction enhances rigidity and reduces vibration during operation.

Suitable for

• Shaping and profiling metal and aluminum components
• Deburring edges and removing weld splatter
• Removing material from plastics, composites and wood
• Surface preparation before painting or bonding
• Detail work and finishing in repair, fabrication and hobby tasks

Key specifications

• Head profile: oval (type E)
• Cutting material: cemented carbide (hard metal)
• Overall head dimensions: 12 x 20 mm
• Single-piece construction for improved rigidity
• Flute design: double notches for efficient chip removal
• Recommended speed range: medium spindle speeds (suitable for straight grinders)
• Net weight: approximately 36 g

How to use

Mount the rotary burr securely in the collet or chuck of a compatible rotary tool or straight grinder. Do not use this cutter in a handheld drill. Select a medium spindle speed appropriate for the 12 x 20 mm head diameter and apply steady, controlled feed without excessive axial force. Use light, overlapping passes for profiling and deburring to avoid overheating and premature wear. Allow the tool to do the cutting; avoid forcing the burr through the workpiece to maintain surface quality and extend life.

Usage recommendations

Wear appropriate personal protective equipment including eye and respiratory protection. Use coolant or periodic breaks when working on heat-sensitive materials to prevent thermal damage. Clean chips from the work area frequently and inspect the burr for wear or damage before each use. Store the tool in a dry place to avoid contamination of the cutting edges.
