Rotary burr GRAPHITE 55H368, single-piece, metal-cutting tool, weight 64 g

GRAPHITE 55H368 rotary burr, single-piece metal-cutting tool, is intended for deburring, shaping and removing material from workpieces made of metal, aluminium and some plastics. The tool is made of cemented carbide and designed for use with compatible rotary tools and straight die grinders; it is supplied as one piece with a pack weight of 64 g. The cutter has an oval (type E) head profile with double notches for efficient chip removal and is optimized for low-speed operation due to its diameter.

Advantages

The cemented carbide construction provides high hardness and excellent abrasive wear resistance, enabling long service life even under heavy use. Double-notched teeth reduce cutting load by producing small chips and improving evacuation, which increases cutting performance and stability during material removal. Precision manufacturing ensures consistent shape and balance for reliable operation in maintenance, repair and metalworking tasks.

Suitable for

• Deburring and shaping metal edges and welds
• Removing excess material from aluminium castings and profiles
• Profiling and smoothing hard plastics
• Surface preparation prior to welding or finishing
• Maintenance and repair work on machinery and automotive parts

Key specifications

• Head shape: oval (type E)
• Material: cemented carbide (HM)
• Overall dimensions: 16 × 25 mm (head diameter × head length)
• Single-piece design for use with rotary tools and straight die grinders
• Tooth pattern: double notches for improved chip removal
• Recommended operating speed: low speeds due to cutter diameter
• Quantity: 1 piece; pack weight: 64 g

How to use

Mount the rotary burr securely in the collet of a compatible straight grinder or die grinder; do not use with a standard hand drill. Set the machine to a low rotational speed appropriate for the cutter diameter and the workpiece material. Approach the workpiece gradually, applying light and steady pressure and using controlled passes to remove material. Keep the tool moving to avoid creating heat concentration or uneven surfaces. Periodically inspect the cutter for wear or clogging and clean chips from the work area to maintain cutting performance.

Usage recommendations

Use appropriate personal protective equipment, including eye protection, gloves and hearing protection. Secure the workpiece before machining. For best results on hard metals, use cutting fluid or intermittent cutting to reduce heat buildup. Replace the cutter once signs of significant wear or reduced cutting performance appear.
