Drill bit set AWTools AW41191 — 5 pieces

AWTools AW41191 — 5 pieces drill bit set contains five individual HSS-G high-speed steel bits in a compact case. Each bit is precision ground with a double-sided flute and a 118° point angle for improved centring and reduced walking. The set is designed for general drilling tasks and is suitable for drilling alloyed and unalloyed steel, grey cast iron, non-ferrous metals and plastics. Packaged together for easy storage and quick access, the set provides spare bits for workshop, construction and DIY use.

Advantages

The drill bits are made from HSS-G high-speed steel, offering high hardness and wear resistance for a range of common materials. Precision grinding and double-sided flutes ensure consistent cutting performance and longer life compared with unground bits. The 118° point angle improves centring on flat surfaces and reduces the need for pilot holes. Supplied in a compact case, the five-piece set keeps bits organised and protected during transport and storage.

Suitable for

• General workshop drilling in steel and cast iron
• Drilling non-ferrous metals such as aluminum and brass
• Plastic component drilling and fabrication
• Construction and on-site maintenance tasks
• Home DIY projects and repairs

How to use

Select the correct drill bit size for the intended hole and secure the bit in the drill chuck. Use an appropriate cutting speed and feed for the workpiece material—lower speeds for harder alloys and higher speeds for softer non-ferrous metals and plastics. Apply steady pressure and allow the drill to do the cutting; withdraw periodically to clear chips when drilling deeper holes. Use cutting fluid or lubrication for steel and cast iron to reduce heat and extend bit life. Store unused bits in the supplied case to prevent damage.

Usage recommendations

For accurate starts on flat or polished surfaces, mark the drilling point or use a centre punch. When drilling hard or alloyed steels, use cutting fluid and moderate speed. For plastics, reduce speed to avoid melting and keep chips clear. Replace bits when wear or chipping affects cutting quality.
