Drill bit set AWTools AW41920 — pack of 5 pieces

The AWTools AW41920 drill bit set — pack of 5 pieces includes five identical high-speed steel drill bits designed for general-purpose drilling. Each bit is made from HSS-G M2 high-speed steel, precision ground and finished with a black oxide coating. The two-cutting-edge geometry and a 135° centering point make these bits suitable for accurate starts and reduced walking. The set is supplied as a pack of five and delivered in a case to keep the bits organized and ready for workshop or on-site use.

Advantages

Drill bits manufactured from HSS-G M2 offer high wear resistance and a low risk of breakage under normal operating conditions. The precision ground cutting edges provide consistent hole quality and reliable cutting performance, while the black oxide surface improves corrosion resistance and reduces friction. The 135° point angle with centering point enhances positioning accuracy and makes the bits effective on a variety of materials.

Suitable for

• Drilling alloyed and unalloyed steel
• Working with grey cast iron
• Drilling non-ferrous metals such as aluminium and copper
• Creating holes in plastic components
• Workshop and on-site maintenance where multiple identical bits are required

Key specifications

• Material: HSS-G M2 high-speed steel
• Coating/finish: Black oxide
• Cutting geometry: Two cutting edges, precision ground
• Point angle: 135° centering point
• Pack quantity: 5 identical drill bits in a case

How to use

Select an appropriate drill speed for the material being machined and secure the workpiece. Clamp the bit into a compatible chuck, ensure correct alignment, and start drilling with moderate feed pressure. For steel and other metals use cutting fluid to reduce heat and extend tool life; for plastics use lower speed and gentle feed to prevent melting. Withdraw the bit periodically to clear chips and check hole quality. Store unused bits in the supplied case to protect the cutting edges.

Usage recommendations

Use appropriate personal protective equipment and follow machine manufacturer guidelines. Regularly inspect bits for wear or chipping and replace when cutting performance declines. For prolonged life on hard or abrasive materials, consider light cutting oil and correct speed/feed adjustments.
