Drill bit set AWTools AW42110 — 5 pieces

AWTools AW42110 — 5 pieces drill bit set is a compact kit of five identical high-speed steel bits with 5% cobalt (HSS-Co). Each drill bit is precision ground with two cutting edges and a centering point featuring a 135° point angle. The set is supplied in a storage case and is intended for general-purpose metal and plastic drilling where spare or multiple bits are required.

Advantages

The HSS-Co material with 5% cobalt provides increased heat resistance and wear resistance compared with standard high-speed steel. Precision ground two-cutting-edge geometry and a 135° centering point deliver stable drilling, reduced walking at the start, and smoother chip evacuation. Supplied as a uniform five-piece set in a case, the bits are convenient for repeated tasks, quick replacement, and organized storage.

Suitable for

• Drilling alloyed and unalloyed steel
• Drilling grey cast iron
• Drilling non-ferrous metals (aluminum, brass, copper)
• Drilling plastics and composite materials
• Workshop use where spare bits or batch drilling is required

Key specifications

• Material: high-speed steel with 5% cobalt (HSS-Co)
• Cutting edges: precision ground, two-cutting-edge geometry
• Point angle: 135° centering point
• Heat resistance: enhanced due to cobalt alloy
• Pack contents: 5 identical drill bits in a storage case

How to use

Select an appropriate drill speed and clamping method for the workpiece material. Secure the bit in the chuck so it runs true, then position the centering point on the mark and start drilling with steady feed pressure. Use cutting fluid or coolant when drilling steels and other heat-sensitive materials to extend tool life. Withdraw the bit periodically to clear chips when drilling deep holes.

Usage recommendations

For best results, match drill speed and feed to the material being worked: lower speeds for harder steels and higher speeds for non-ferrous metals and plastics. Apply cutting fluid when machining steels or alloys, and store the bits in their case to protect cutting edges between uses.
