Drill bit pack AWTools AW42045 — 10 pcs

AWTools AW42045 — 10 pcs drill bit pack contains ten individual HSS-Co high-speed steel bits with 5% cobalt, precision ground with two-cutting edges and a 135° centering point angle. The set is supplied in a compact case and is intended for general drilling tasks with compatible drills. Designed for use on a range of common materials, these drill bits deliver higher heat resistance and improved wear life compared with standard HSS bits, making them suitable for repeated work or as replacements during construction, repair and maintenance jobs.

Advantages

The cobalt-alloyed high-speed steel composition provides increased hardness and thermal stability at elevated drilling temperatures. Precision ground two-flute geometry and a 135° centering point improve hole accuracy and reduce walking on start-up. Supplied in a case, the pack offers organized storage and quick access to multiple sizes for continuous work without frequent interruptions to replace bits.

Suitable for

• Drilling alloyed and unalloyed steel
• Working with grey cast iron
• Drilling non-ferrous metals (aluminium, brass, copper)
• Drilling plastics and general-purpose workshop tasks

How to use

Select the appropriate drill bit size from the AWTools AW42045 pack and secure it in the drill chuck according to the drill manufacturer’s instructions. Position the workpiece securely in a vice or with clamps to prevent movement. For best results on metals, use cutting fluid or coolant to reduce heat and prolong bit life; for plastics, control speed to avoid melting. Start drilling at a moderate speed to allow the 135° centering point to locate the hole, then increase speed as appropriate for the material and bit size. Withdraw periodically to clear chips when drilling deep holes.

Usage recommendations

Use appropriate personal protective equipment (safety glasses and gloves), select correct drill speed and apply lubrication when working with metals to extend the life of the cobalt HSS bits. Store the bits in the supplied case in a dry place to avoid corrosion and to keep them organized for future tasks.
