Engraver bit GRAPHITE 55H057 — single piece, weight 14 g

Replacement engraver bit GRAPHITE 55H057 supplied as a single piece weighing 14 g. Compatible with handheld or benchtop engraving tools, this consumable bit is designed for controlled material removal in marking, carving and light cutting operations. The component is intended for maintenance and repair of engraving equipment and is sold per pack of 1.

Advantages

The GRAPHITE 55H057 engraver bit offers a compact, easy-to-install replacement option that maintains consistent contact and predictable wear during engraving tasks. Manufactured from aluminium oxide, the bit provides effective abrasion for shaping, smoothing and removing surface residues across a range of materials while retaining shape under typical engraving loads. Its bullet profile and defined dimensions support precision work in confined areas.

Suitable for

• Precision marking and engraving on metal, wood and plastics
• Carving small details and light cutting tasks
• Maintenance and replacement in handheld or benchtop engraving tools
• Deburring and smoothing edges after machining or cutting

• Weight per piece: 14 g
• Sold as: single piece (pack of 1)

How to use

Fit the GRAPHITE 55H057 into the collet or chuck of a compatible mini-grinder or engraving tool with a 3.2 mm drive shank, ensuring the bit is seated securely and the tool is powered off when installing. Operate the tool at appropriate speeds for the material being worked — moderate to high speed for metals and lower speeds for plastics and wood — and apply light, steady pressure to guide the bullet-shaped bit for marking, carving or light cutting. Allow the abrasive surface to do the work and avoid excessive lateral force that may accelerate wear or cause breakage.

Usage recommendations

Use proper personal protective equipment, including eye protection and a dust mask. Match rotational speed to the material and replace the bit when abrasive performance declines or when the profile is worn beyond effective use. Store the bit in a dry place and avoid exposing it to impacts that could chip the abrasive.
