Drill Bit BRÜDER MANNESMANN M54399

The BRÜDER MANNESMANN M54399 drill bit is a high-speed steel (HSS) tool designed for conventional drilling tasks in a range of materials. Its HSS construction provides a balance of hardness and heat resistance, allowing sustained cutting performance during repeated use. The compact packaging dimensions make it easy to store and transport, while the drill geometry suits general-purpose metalworking and construction needs.

Advantages

This HSS drill bit offers high wear resistance and thermal stability compared with standard carbon-steel bits, resulting in longer service life under typical workshop conditions. The cutting edges are ground to provide consistent hole quality and efficient chip evacuation. Its compact size and straightforward design make it compatible with most handheld and bench drills, enabling reliable performance across routine tasks.

Suitable for

• Drilling holes in mild steel and non-ferrous metals
• General-purpose drilling in wood and certain plastics
• Home improvement and DIY projects
• Workshop and light industrial maintenance

Key specifications

• Material: High-speed steel (HSS)
• Tool type: Twist drill bit for general-purpose drilling
• Typical applications: Metal, wood, and plastic
• Compact packaging dimensions: shallow depth and small height for easy storage

How to use

Select the correct drill speed and feed for the material you are working with: lower speeds for harder metals and higher speeds for softer materials. Secure the workpiece and clamp it if necessary to prevent movement. Fit the drill bit into the chuck and ensure it is tightened firmly and runout is minimal. Apply steady pressure and allow the drill to cut; withdraw occasionally to clear chips when drilling deeper holes. For metalworking, use appropriate cutting fluid to reduce heat and extend tool life.

Usage recommendations

Use the drill bit within recommended speed ranges for the material, maintain a straight drilling axis, and replace the bit when wear or chipping affects hole quality. Store in a dry place to avoid corrosion and handle with protective equipment as required for the work environment.
