Drill bit set AWTools AW40964 — 4 pieces, pack weight 650 g

The AWTools AW40964 drill bit set contains four precision bits in a compact aluminium case, total pack weight 650 g. Manufactured from high-speed HSS steel and finished with an aluminium chromium nitride (AlCrN) black coating, these bits are intended as replacement or accessory drilling tools for handheld and stationary drills. The spiral flute geometry promotes efficient chip evacuation and faster penetration, while laser-marked size engravings on each shank enable you to monitor hole diameter during drilling. The set is suitable for standard repair, construction and DIY tasks involving non-ferrous metals, thin-walled steel sheets and plastics.

Advantages

High-speed HSS construction provides wear resistance and durability under typical drilling loads, and the AlCrN coating improves surface hardness and heat resistance. Spiral flutes ensure a clean cut and quicker chip removal for smoother holes. Laser-marked size indicators make it easy to check and control drill diameter during operation. The included aluminium case protects bits in storage and transport and keeps the set organized.

Suitable for

• Drilling non-ferrous metals such as aluminium and brass
• Working with thin-walled steel sheets and metal panels
• Plastics and composite materials
• General repair, maintenance and DIY drilling tasks

How to use

Select the appropriate bit size for the required hole diameter and secure it firmly in the drill chuck. Use recommended drill speeds for HSS bits and apply steady, moderate pressure; allow the drill to do the work rather than forcing it. For thicker or harder workpieces consider reducing speed and using cutting fluid to extend bit life and improve hole quality. Monitor the laser-engraved marks to verify hole progress and diameter while drilling. After use, clean swarf from the flutes and store bits in the aluminium case to prevent damage.

Usage recommendations

For best performance when drilling metals, use appropriate cutting fluid and maintain consistent feed rate to minimise heat build-up. Avoid excessive axial force and high speeds on thin-walled materials to reduce the risk of deformation or tearing.
