GRAPHITE drill bit 55H229 — single-piece metal drilling bit, weight 70 g

GRAPHITE drill bit 55H229 is a single-piece metal drilling bit sold as one unit with a net weight of 70 g. Designed for standard drill chucks, this bit is intended for general metalworking and construction applications where a single, ready-to-use replacement or spare is required. The bit's single-piece construction provides consistent performance during drilling tasks.

Advantages

The single-piece design reduces the number of joints and potential weak points, offering stable rotation and predictable wear. At 70 g net weight the bit is easy to handle and store. Compatibility with common drill chucks and general-purpose geometry makes it suitable for a wide range of metal and construction drilling tasks. Supplied individually, it is convenient for small-scale projects, quick replacement or when only one spare bit is needed.

Suitable for

• Drilling metal sheets and profiles
• Light construction and installation work
• Workshop repairs and maintenance
• Replacement of a worn or damaged drill bit

Key specifications

• Single-piece metal construction for consistent performance
• Net weight: 70 g
• Designed for use with standard drill chucks
• General-purpose geometry suitable for metalworking and construction
• Sold individually (1 pc)

How to use

Install the GRAPHITE 55H229 drill bit in a compatible drill chuck and secure it firmly according to the drill manufacturer’s instructions. Select an appropriate rotational speed and feed for the workpiece material, apply steady pressure and allow the bit to cut without forcing. Use cutting fluid or lubricant when drilling harder metals to extend bit life and reduce heat. After use, clean chips from the flutes and store the bit in a dry place.

Usage recommendations

For best results, choose drill speeds and feed pressure that match the workpiece material, and use cutting fluid when drilling steel or other hard alloys. Inspect the bit before each use for wear or damage, and replace it if the cutting edges are significantly blunt or chipped. Keep the bit dry and free of corrosion to maintain performance.
