Drill bit set AWTools AW41202 — 13 pieces, total weight 240 g

The AWTools AW41202 drill bit set contains 13 pieces with a total weight of 240 g. The bits are manufactured from HSS (high speed steel) and hardened, with precision ground flutes that support efficient chip removal and steady cutting performance. The set is designed for general drilling tasks and fits standard drill chucks, making it suitable for home improvement, DIY and light professional use where a compact multi-piece solution is needed.

Advantages

The hardened HSS construction provides wear resistance and sustained cutting ability. Precision grinding reduces friction and promotes smooth drilling, while the geometry of the flutes improves chip evacuation. The compact set of 13 pieces covers common drill sizes for a range of materials, and the lightweight total weight of 240 g makes the kit easy to store and transport.

Suitable for

• Drilling alloyed and unalloyed steel
• Working with cast iron
• Drilling non-ferrous metals such as aluminium and copper
• Making holes in PVC and other plastics
• General home improvement and DIY projects

How to use

Select a drill bit size appropriate for the required hole diameter and secure it in a standard drill chuck. Set the drill to the recommended speed for the workpiece material and apply steady, even pressure while drilling. Use cutting fluid or coolant when drilling harder metals to extend tool life and improve chip evacuation. Withdraw the bit periodically to clear chips and avoid overheating; allow the bit to cool if it becomes excessively hot.

Usage recommendations

For best results, match drill speed and feed to material hardness: higher speeds for softer non-ferrous metals and plastics, and lower speeds with cutting fluid for alloyed steels and cast iron. Inspect bits for wear or blunt edges before use and replace damaged bits to maintain drilling accuracy and safety.
