Drill bit set AWTools AW41885 — pack of 5

AWTools AW41885 — pack of 5 HSS-G M2 drill bits designed for routine drilling tasks in workshop and home environments. Each pack contains five identical, precision-ground bits with two cutting edges and a 135° centering point angle. The bits feature a black oxide finish for improved wear resistance and lower risk of breakage. Supplied in a compact case for storage and transport, this set is intended as replacement bits or spares for general maintenance and everyday drilling operations.

Advantages

The drill bits are manufactured from HSS-G M2 high-speed steel, offering high wear resistance and consistent cutting performance. Precision grinding ensures accurate geometry and stable drilling, while the black oxide surface treatment reduces friction and helps protect against corrosion. The 135° centering point improves guidance on flat surfaces and reduces wandering during plunge starts, and the two-cutting-edge design balances cutting efficiency with chip evacuation to lower the risk of breakage.

Suitable for

• Drilling alloyed and unalloyed steel
• Drilling grey cast iron
• Working with non-ferrous metals (aluminium, copper, brass)
• Drilling plastic components
• Workshop maintenance, tool replacement, and spare storage

Key specifications

• Material: HSS-G M2 high-speed steel
• Cutting geometry: precision ground, two cutting edges
• Point angle: 135° centering point
• Surface finish: black oxide
• Pack quantity: 5 identical drill bits in a storage case
• Intended use: standard drilling in metals and plastics

How to use

Select a drill speed appropriate to the material being drilled and secure the workpiece to prevent movement. Install the drill bit into a compatible chuck and ensure it is properly centered and tightened. For metals, use cutting fluid or coolant to extend tool life and improve chip removal; for plastics, reduce feed rate and avoid excessive heat generation. Start drilling with light pressure to establish the centering point, then apply steady pressure while maintaining correct speed. After use, clean the bits of chips and coolant and store them in the provided case.

Usage recommendations

To maximize service life, match speed and feed to the material, use appropriate lubrication for metal drilling, and avoid excessive side loading. Replace worn bits before they cause poor hole quality or increased load on the drill chuck.
