Drill bit set AWTools AW41905 — pack of 5

AWTools AW41905 — pack of 5 drill bits is a set of five identical HSS-G M2 high-speed steel bits supplied in a single case. Each bit is precision ground with two cutting edges, black oxide finish and a centering point with a 135° point angle. The design and materials provide high wear resistance and a reduced risk of breakage, making the set suitable for workshop, construction and home repair tasks where multiple identical drill bits are needed.

Advantages

The drill bits are manufactured from HSS-G M2 high-speed steel and precision ground for consistent cutting performance. A black oxide coating improves surface durability and corrosion resistance while minimizing friction. The two-cutting-edge geometry combined with a 135° centering point delivers accurate starts and stable drilling in a variety of materials. Supplied as a five-piece pack in a case, the set ensures convenient storage and quick replacement of worn bits.

Suitable for

• Drilling alloyed and unalloyed steel
• Drilling grey cast iron
• Drilling non-ferrous metals (aluminium, copper, brass)
• Drilling plastics and composite materials
• General workshop, construction and home repair applications

How to use

Secure the drill bit in the chuck of a standard drill, ensuring correct alignment and tight clamping. Select an appropriate speed and feed for the material being drilled: lower speeds for hard or alloyed steels and higher speeds for softer non-ferrous metals and plastics. Use cutting fluid or lubricant when drilling steels to prolong bit life and reduce heat. Apply steady pressure and allow the bit to cut without excessive force; clear chips regularly to avoid clogging and overheating. After use, clean the bits and store them in the supplied case.

Usage recommendations

For best results when drilling steels and cast iron, use a suitable cutting fluid and moderate speed. For non-ferrous metals and plastics, use higher speeds and minimal coolant to prevent material sticking. Replace bits when signs of wear or chipping appear to maintain hole quality and minimize the risk of breakage.
