Rotary burr GRAPHITE 55H363 — 1 pc, hand tool accessory, 22 g

GRAPHITE 55H363 is a single rotary burr designed as an accessory for rotary tools and die grinders. This oval (type E) cemented carbide burr measures 6 × 10 mm and weighs 22 g, providing a compact cutting solution for shaping, deburring and material removal on metal, aluminium and plastic. The cutter is manufactured for straight grinders and compatible with standard rotary tool collets; it is not intended for use with a drill. Double-notched flutes reduce chip size and improve chip evacuation, supporting stable cutting performance at high speeds.

Advantages

The cemented carbide construction ensures high hardness and abrasive wear resistance, making the burr durable even under heavy use and in harsh conditions. Precision workmanship delivers consistent cutting geometry that maintains performance over time. The double notches facilitate efficient stock removal and produce smaller chips, which reduce load on the cutting edges and improve operator control. Its compact 6 × 10 mm oval profile is optimized for high-speed operation and fine finishing in confined areas.

Suitable for

• Shaping and profiling of metal parts
• Deburring edges on aluminium components
• Removing excess material from plastic mouldings
• Detail finishing in tight or curved surfaces
• High-speed material removal where small chips are preferred

How to use

Install the burr into a compatible rotary tool or straight grinder collet and ensure it is securely tightened according to the tool manufacturer’s instructions. Operate the tool at high speed appropriate for small-diameter carbide burrs and apply light, steady pressure — avoid excessive force to prevent premature wear or breakage. Use controlled passes to shape, deburr or remove material; allow the cutter to do the work rather than forcing it. Periodically clear chips from the work area and inspect the burr for wear or damage before continuing.

Usage recommendations

Use appropriate personal protective equipment including eye and respiratory protection. Match rotational speed to the workpiece material and the burr diameter; higher speeds are suitable for this 6 mm cutter, while very low speeds may cause clogging or poor cutting. For best results on aluminium and plastics, use light feeds and frequent chip clearing to prevent built-up edges. Do not use this burr with a handheld drill; use only compatible rotary tools or straight grinders.
