Drill bit GRAPHITE 57H242 — single-piece metal drilling bit, weight 54 g

GRAPHITE 57H242 single-piece metal drilling bit is a spare drill designed for use in general metalworking and workshop drilling tasks. Supplied as one piece per pack with a net weight of 54 g, this drill bit features a wood spade profile adapted to increase drilling speed and reduce material tear-out. The bit is intended for use with compatible drill chucks or hexagonal quick-change holders on cordless tools and magnetic adapters.

Advantages

The special spade-shaped blade profile increases cutting efficiency and helps prevent chipping or tearing of the drilled surface. A hexagonal quick-change holder provides secure fit and fast interchangeability with magnetic holders or quick-change adapters, improving workflow in workshop and on-site operations. The single-piece construction offers solid rigidity during drilling, supporting consistent hole quality in metal and mixed-material applications.

Suitable for

• General metalworking and light fabrication tasks
• Workshop repairs and maintenance where a spare drill bit is needed
• Drilling jobs requiring faster penetration and reduced material tear-out
• Use with cordless screwdrivers and magnetic quick-change holders

Key specifications

• Design: single-piece metal drilling bit with spade-profile blade
• Weight: 54 g (net weight of the unit)
• Connection: hexagonal quick-change holder compatible with magnetic adapters
• Primary application: drilling in metal and mixed materials where spade profile improves chip evacuation

How to use

Install the drill bit into a compatible chuck or insert the hexagonal shank into a quick-change holder or magnetic adapter designed for cordless screwdrivers. Secure the bit before starting the tool. Use appropriate drilling speeds and feed pressure for the material being worked on; lower speeds and steady pressure are recommended for harder metals. Periodically withdraw the bit to clear chips if drilling deep holes. After use, clean the bit and store it in a dry place to prevent corrosion.

Usage recommendations

For best results, select drilling speed and lubrication suited to the specific metal type. Use cutting fluid for harder metals to extend bit life and maintain hole quality. Replace the bit if wear or damage to the cutting profile is visible to avoid poor hole finish or increased tool load.
