Drill bit pack AWTools AW42032, 10 pieces

AWTools AW42032 drill bit pack contains 10 identical HSS-Co high-speed steel bits with 5% cobalt, precision ground and finished with a 135° centering point. The set is supplied in a compact case for storage and transport and is intended for general-purpose drilling in workshops, construction and maintenance environments. Designed to offer increased heat resistance and wear life compared with standard HSS drills, these two-cutting-edge bits are suitable for a range of common materials.

Advantages

The cobalt-alloyed HSS-Co composition increases hardness and maintains cutting performance at higher temperatures, making the bits more resistant to softening during prolonged or high-speed drilling. Precision grinding and two cutting edges ensure accurate hole positioning and consistent chip evacuation. The 135° point angle improves centering and reduces walking on metal surfaces, while the supplied case keeps the set organised and protects the bits between uses.

Suitable for

• Drilling alloyed and unalloyed steel
• Drilling grey cast iron
• Drilling non-ferrous metals such as aluminium and copper
• Drilling plastics and general workshop materials
• Use as spare or replacement bits for professional and DIY applications

Key specifications

• Material: HSS-Co high-speed steel with 5% cobalt
• Number of pieces: 10 bits
• Point angle: 135° centering point
• Cutting edges: precision ground, two cutting edges
• Heat resistance: improved vs. standard HSS due to cobalt alloy
• Packaging: compact storage case included

How to use

Secure the required bit in a compatible drill chuck, ensure the workpiece is clamped or supported, and select an appropriate drill speed and feed for the material. Start drilling with light pressure to allow the 135° centering point to locate the hole, then increase pressure steadily while maintaining coolant or cutting lubricant when machining metals. Retract the bit periodically for deep holes to clear chips and avoid overheating. After use, clean the bits and return them to the case to prevent damage and corrosion.

Usage recommendations

For optimal life and hole quality, use cutting fluid when drilling metals, choose lower speeds for hard or alloyed steels, and moderate speeds for non-ferrous metals and plastics. Replace worn bits promptly to maintain accuracy and reduce the risk of workpiece damage.
