Drill bit set AWTools AW42005 — 25 pieces, pack weight 1.2 kg

AWTools AW42005 — 25 pieces drill bit set supplied in a plastic case. The pack weight is 1.2 kg and the set is intended as replacement or consumable drill bits for general drilling tasks. Bits are made of HSS-G M2 high-speed steel, precision ground with two cutting edges and a black oxide finish. Each bit features a centering point with a 135° point angle and is designed for drilling alloyed and unalloyed steel, grey cast iron, non-ferrous metals and plastic.

Advantages

The drill bits are manufactured from HSS-G M2 high-speed steel, providing high wear resistance and reduced risk of breakage compared with lower-grade steels. Precision grinding and two cutting edges ensure accurate hole results and consistent cutting performance. The black oxide surface treatment improves corrosion resistance and reduces friction during drilling. The 135° centering point supports stable drilling and better guidance when starting holes on different materials. Supplied in a plastic case for organised storage and transport.

Suitable for

• Workshop and garage drilling tasks requiring a range of bit sizes
• Construction site use where bulk replacement bits are needed
• Home DIY projects involving metal, cast iron or plastic
• Maintenance and repair work on machinery and equipment

How to use

Select the appropriate drill bit size for the material and hole diameter required. Secure the workpiece and clamp if necessary to prevent movement. Fit the drill bit into a compatible drill chuck, tighten securely and set the drill to a recommended speed for HSS bits and the material being drilled. Use cutting fluid or lubrication when drilling harder metals to reduce heat and prolong bit life. Apply steady pressure and allow the bit to cut; avoid excessive force that could cause breakage. After use, clean chips from the bit, inspect for wear or damage and return bits to the plastic case for storage.

Usage recommendations

For best results, match drill speed and lubrication to the material: lower speeds and cutting fluid for hard or alloyed steels, medium speeds for non-ferrous metals and higher speeds for plastics. Replace worn bits to maintain hole quality and reduce risk of breakage.
