Drill bit AWTools AW42065, pack of 10 pieces

AWTools AW42065 drill bit, pack of 10 pieces, is a set of precision ground HSS-Co high-speed steel bits containing 5% cobalt designed for reliable drilling in metal and plastic. Each bit features a 135° centering point and two cutting edges to provide accurate starts, reduced walking and consistent hole quality. Supplied as a set of ten identical replacement bits in a storage case, the pack is intended for workshop, construction and repair environments where spare or multiple drill bits are required for continuous work and quick replacement.

Advantages

The HSS-Co material with 5% cobalt increases heat resistance and wear life compared with standard high-speed steel, helping the drill bits retain hardness at higher temperatures. Precision ground two-cutting-edge geometry and a 135° point angle deliver improved centering and cleaner holes in alloyed and unalloyed steel, grey cast iron, non-ferrous metals and plastics. Supplied in a case and packaged as ten identical pieces, the set simplifies inventory, reduces downtime and ensures consistent drilling performance across repeated operations.

Suitable for

• Drilling alloyed and unalloyed steel
• Drilling grey cast iron
• Drilling non-ferrous metals (aluminium, brass, copper)
• Drilling plastic components
• Workshop, construction and repair tasks requiring spare bits

Key specifications

• Material: HSS-Co high-speed steel with 5% cobalt
• Geometry: precision ground, two cutting edges
• Point angle: 135° centering point
• Pack quantity: 10 identical drill bits in a storage case
• Typical use: metal and plastic drilling

How to use

Secure the appropriate drill bit in the chuck of a drill or drill press, ensuring proper alignment and tightening. Select a suitable cutting speed and feed for the workpiece material; use lower speeds and steady feed for harder alloyed steels and higher speeds for non-ferrous metals and plastics. Apply cutting fluid or coolant when drilling steels and cast iron to reduce heat and prolong tool life. Start drilling with light pressure to engage the 135° centering point, then increase feed as the drill bit cuts through the material. After use, clean chips from the flutes and store the bits in their case to protect the cutting edges.

Usage recommendations

To maximize life and performance, use cutting fluid for ferrous materials, avoid excessive speeds on hard alloys, and replace worn bits promptly; maintain appropriate speeds and steady feed to reduce heat build-up and prevent premature wear.
