Drill bit set AWTools AW42042 — 10-piece pack

The AWTools AW42042 — 10-piece drill bit set is a collection of identical high-speed steel bits supplied in a compact case for convenient storage and transport. Each drill bit is made of HSS-Co (high-speed steel with 5% cobalt), precision ground and features two cutting edges and a centering point with a 135° point angle. The set is intended for general drilling tasks in metalworking and workshop environments where multiple spare bits or consistent replacements are required.

Advantages

The HSS-Co composition with 5% cobalt provides increased heat resistance and improved wear life compared with standard HSS, which supports sustained drilling at higher temperatures. Precision grinding and two cutting edges deliver accurate hole geometry and consistent performance. The 135° centering point reduces walking on the workpiece and improves centering when starting holes in a variety of materials. Supplied in a case, the pack of 10 ensures quick replacement and keeps bits organized for jobsite or workshop use.

Suitable for

• Drilling alloyed and unalloyed steel
• Drilling grey cast iron
• Drilling non-ferrous metals (such as aluminium and copper)
• Drilling plastics and other synthetic materials
• Workshop maintenance and construction tasks requiring multiple spare bits

Key specifications

• Number of pieces: 10
• Point geometry: 135° centering point
• Cutting edges: two-cutting-edge design, precision ground
• Heat resistance: improved compared with standard HSS due to cobalt content
• Storage: supplied in a compact case for organization and transport

How to use

Select the correct drill bit size for the hole required and secure the workpiece to prevent movement. Install the bit in a compatible drill chuck and tighten securely. Use appropriate cutting speeds and feed rates for the material being drilled; reduced speed and steady feed are recommended for harder or thicker materials to avoid overheating. Apply cutting fluid or lubricant when drilling steel or other metals to extend tool life and improve chip evacuation. After use, clean chips from flutes and store bits in the supplied case to protect the cutting edges.

Usage recommendations

For best results when drilling alloyed steels and other harder materials, use lower spindle speeds and steady pressure, and employ cutting fluid to reduce heat buildup. Replace worn bits promptly to maintain hole quality and accuracy; the 10-piece pack provides ready replacements to minimise downtime.
