Drill bits AWTools AW41940 pack of 5 — metal/concrete/general purpose

AWTools AW41940 pack of 5 drill bits is a set of general-purpose bits designed for everyday workshop, construction and maintenance tasks. Made of HSS-G M2 high-speed steel with precision ground two-cutting edges and a black oxide finish, these bits are intended for use with standard drills and drill drivers and come packed in a compact case for organised storage and transport.

Advantages

The HSS-G M2 construction provides high wear resistance and low risk of breakage compared with lower-grade steels. Precision grinding and two cutting edges ensure straight drilling and consistent hole quality, while the black oxide surface treatment improves corrosion resistance and reduces friction. A centering point with a 135° point angle helps prevent walking and improves accuracy on alloyed and unalloyed steel, cast iron, non-ferrous metals and plastics.

Suitable for

• General metalworking and maintenance drilling
• Drilling alloyed and unalloyed steels
• Working with grey cast iron and non-ferrous metals
• Drilling plastic components and assemblies
• Everyday workshop and site repair tasks

Key specifications

• Material: HSS-G M2 high-speed steel
• Cutting geometry: precision ground, two-cutting edges
• Surface finish: black oxide
• Point angle: 135° centering point
• Pack contents: 5 drill bits supplied in a storage case

How to use

Secure the appropriate bit in the drill or drill driver chuck and tighten firmly. Select a suitable drill speed for the material: lower speeds for steels and cast iron, higher speeds for non-ferrous metals and plastics. Use steady pressure and allow the bit to cut without forcing; back off occasionally to clear chips when drilling deeper holes. For metal work, apply suitable cutting fluid to reduce heat and extend bit life.

Usage recommendations

Store bits in the supplied case to protect cutting edges. Replace bits when signs of wear or chipping appear. Choose correct speed and cooling for the material to maximise service life and maintain hole accuracy.
