Rotary burr GRAPHITE 55H365 — single piece, metalworking tool, 22 g

GRAPHITE 55H365 rotary burr — single piece, metalworking tool, 22 g — is a cemented carbide oval (type E) burr designed for material removal, deburring and shaping tasks. The cutter measures 10 x 16 mm and is intended for use with rotary tools and straight die grinders (not for use with handheld drills). Its compact size and oval profile make it suitable for precision cutting, finishing and spot machining on metal, aluminum and selected plastics.

Advantages

The solid cemented carbide construction provides high hardness and excellent resistance to abrasive wear, resulting in long service life even under heavy-duty conditions. Double notches on the cutting head promote efficient chip evacuation and reduce loading on the cutting edges, producing smaller chips and maintaining cutting performance. The burr’s diameter is optimized for medium-speed operation, balancing control and material removal rate.

Suitable for

• Removing burrs and flash from metal parts
• Shaping and finishing edges on aluminum components
• Spot machining and precision profiling on plastics
• Cleaning weld seams and preparing joints for further processing
• Detail work in confined or hard-to-reach areas

Key specifications

• Head shape: oval (type E)
• Head dimensions: 10 x 16 mm
• Material: cemented carbide (HM)
• Notch type: double-fluted chip removal
• Recommended tool: straight die grinder / rotary tool (not for use with drill)
• Intended materials: steel, aluminum, plastics
• Weight: approximately 22 g (single piece)
• Speed range: suited to medium rotational speeds

How to use

Install the rotary burr firmly in the collet or chuck of a straight die grinder or compatible rotary tool, ensuring correct alignment and secure clamping. Start the tool at a low speed to confirm stability, then increase to a medium speed appropriate for the material being worked. Use light, steady pressures and controlled passes; avoid forcing the burr into the workpiece. Move the tool smoothly along the contour to achieve a uniform finish and to prevent excessive wear or overheating of the cutter. Regularly inspect the burr for wear and replace it when cutting efficiency declines.

Usage recommendations

For best results, use appropriate personal protective equipment (safety glasses, gloves, hearing protection) and maintain proper ventilation when machining metals or plastics. Select a medium rotational speed matched to the cutter diameter and work material, and use coolant or intermittent operation to reduce heat buildup when necessary. Do not operate the burr in a handheld drill; use only straight grinders or rotary tools designed for carbide burrs.
