metal drills wolfcraft 7544010

The wolfcraft 7544010 metal drills are a set of precision HSS twist drills designed for drilling in steel, cast steel, annealed cast iron, grey cast iron, non-ferrous metals and plastics. Supplied in a plastic bag on card, the set offers drills with a 118° point angle and a spiral section engineered for decreasing diameter and increasing core for improved chip evacuation and stability.

Advantages

These metal drills follow DIN 338 and are precision ground for accurate bore quality. Constructed from high-speed steel (HSS), they provide high durability under heavy loads and maintain cutting performance over repeated use.

Suitable for

• Drilling holes in steel and cast steel
• Working with annealed and grey cast iron
• Drilling non-ferrous metals such as aluminium and brass
• Creating holes in plastic materials

How to use

Select the appropriate drill size for the required hole diameter and secure the workpiece to prevent movement. Mount the drill in a compatible chuck, ensure the drill is perpendicular to the workpiece, and use steady feed pressure. Apply appropriate cutting speed and, for harder materials, use cutting fluid to reduce heat and prolong drill life. Clear chips regularly and avoid excessive side load to prevent breakage.

Usage recommendations

For best results, use a drill press or a stable hand drill with correct speeds for the material being drilled; use cutting oil when working with steel or cast iron and moderate speeds for non-ferrous metals and plastics to avoid melting or clogging.
