Drill bit pack AWTools AW42030, 10 pieces

Pack of 10 AWTools AW42030 drill bits made of HSS-Co high-speed steel with 5% cobalt, precision ground and featuring two-cutting edges and a centering point with a 135° point angle. This multi-pack provides multiple identical bits in a single case, designed for general-purpose drilling in metal, cast iron, non-ferrous metals and plastics. The construction and material composition prioritise heat resistance and durability for repeated use in trade and DIY environments.

Advantages

The AWTools AW42030 set combines a cobalt-alloyed HSS composition with precision grinding to provide improved wear resistance and cutting performance compared with standard HSS bits. The two-cutting-edge geometry and 135° centring angle reduce walking at the drill start and support stable hole formation. High heat resistance extends life during continuous drilling and the supplied case keeps all ten identical bits organised and protected.

Suitable for

• Drilling alloyed and unalloyed steel
• Working with grey cast iron
• Drilling non-ferrous metals such as aluminium and copper
• Drilling plastic components for assembly or prototypes
• Tradespeople and DIYers needing multiple replacement bits on site

Key specifications

• Material: HSS-Co high-speed steel with 5% cobalt
• Tip geometry: 135° centering point
• Cutting edges: precision-ground, two-cutting-edge design
• Pack contents: 10 identical drill bits in a case
• Intended use: metal, cast iron, non-ferrous metals and plastics
• Properties: high heat resistance and enhanced durability

How to use

Select a bit size from the AW42030 pack that matches the required hole diameter and secure it in a compatible drill chuck. Use appropriate cutting speed, lubrication and feed for the work material: lower speeds and cutting fluid for hard or alloyed steels, moderate speeds for non-ferrous metals and plastics. Apply steady pressure and allow the drill to clear chips regularly to avoid overheating. Replace worn bits from the pack as needed to maintain consistent drilling quality.

Usage recommendations

For best results when drilling metals, use cutting fluid or coolant to reduce heat and extend bit life. Start holes with the centering point at low speed to prevent walking, and maintain firm, even pressure. Store the bits in their case to protect the cutting edges and keep sizes organised.
