Drill bit set AWTools AW40961 — pack of 3 pieces, total weight 440 g

AWTools AW40961 drill bit set — pack of 3 pieces, total weight 440 g — is a compact selection of high-speed HSS drill bits coated with aluminium chromium nitride (AlCrN) and finished in black. The set is supplied in an aluminium case and features a spiral flute geometry designed to provide faster chip evacuation and a clean cutting action. Laser-marked size engravings on each bit make it easy to monitor drill diameter during use. Intended for general-purpose drilling of non-ferrous metals, thin-walled steel sheets and plastics, the set supports common repair, installation and light construction tasks.

Advantages

The AWTools AW40961 set combines HSS material strength with an AlCrN coating to improve wear resistance and thermal stability during drilling. Spiral flutes promote efficient chip removal and help maintain a clean hole finish, while the blackened surface reduces glare and friction. Laser-etched size markings provide quick visual identification of bit diameters. The included aluminium case protects the bits and keeps them organized for transport and storage.

Suitable for

• Drilling non-ferrous metals such as aluminium and copper
• Working with thin-walled steel sheets and metal panels
• Drilling various plastics and composite materials
• Repair, installation and light construction tasks requiring a small multi-piece set

Key specifications

• Total weight: 440 g (including aluminium case)
• Flute design: spiral/helix for fast chip evacuation
• Marking: laser-engraved size markings on each bit
• Packaging: aluminium protective case
• Suitable drill types: compatible with standard handheld and stationary drills

How to use

Select the appropriate drill bit size using the laser-etched markings and securely clamp the bit in the drill chuck. Use a suitable drill speed and steady feed pressure for the material being machined; lower speeds are recommended for harder alloys and thin steel sheets to avoid overheating. For plastics and softer non-ferrous metals, moderate speeds with controlled feed produce clean holes. The spiral flute geometry facilitates chip removal; periodically withdraw the bit to clear chips during deeper holes. The bits can be used without pre-drilling in many applications, but when accuracy is critical, use a center punch or pilot drill to locate the hole.

Usage recommendations

For best tool life and hole quality, use appropriate cutting fluid or lubricant when drilling metals, avoid excessive feed pressure, and allow the AlCrN coating to reduce surface friction and heat buildup. Store the bits in the aluminium case to protect cutting edges and maintain marking legibility.
