Drill bit set AWTools AW41860 — 10 pieces

AWTools AW41860 — 10 pieces drill bit set supplied in a compact case for storage and transport. The bits are made of HSS-G M2 high-speed steel with precision ground two-cutting edges and a black oxide finish. Each bit features a centering point with a 135° point angle and is designed for repeated general-purpose drilling tasks where multiple identical replacement bits are useful.

Advantages

The HSS-G M2 material and precision grinding ensure consistent cutting performance and extended tool life compared with standard carbon-steel bits. The black oxide surface treatment improves wear resistance and reduces friction during drilling. The 135° centering point offers accurate start-up and lower risk of walking, while the two-cutting-edge geometry provides clean holes and reduced breakage risk. Supplied as a pack of ten identical bits in a case, the set is convenient for workshop, construction, and maintenance environments.

Suitable for

• Drilling alloyed and unalloyed steel
• Working with grey cast iron
• Drilling non-ferrous metals such as aluminium and bronze
• Creating holes in plastic components
• Repetitive drilling operations requiring multiple replacement bits

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
• Number of pieces: 10 identical drill bits supplied in a case
• Intended use: general-purpose drilling of metals and plastics

How to use

Select an appropriate bit from the case and secure it firmly in the drill chuck. Mark the drilling position and, if required, use a centre punch to enhance accuracy. Start drilling at a low speed to establish the hole and then increase speed according to the workpiece material. Use cutting fluid or coolant when drilling steels and alloyed materials to extend bit life and improve hole quality. Remove chips periodically to prevent clogging and allow the bit to cool.

Usage recommendations

For best results when drilling steels and other hard materials, apply suitable cutting fluid, maintain moderate feed pressure, and avoid excessive speeds. Store the bits in their case to protect cutting edges and keep them dry to prevent corrosion despite the black oxide finish.
