Drill bit set AWTools AW40997 — 3 pieces, pack weight 100 g

AWTools AW40997 drill bit set contains three HSS titanium nitride (TiN) coated bits in a compact wooden case. The set is intended as replacement or consumable drill bits for general drilling tasks in workshops, maintenance and DIY projects. Laser-marked size engravings on each bit help monitor drilling depth and hole size during use while the TiN coating reduces friction and heat for longer life and more consistent cutting performance.

Advantages

The bits are made of high-speed steel (HSS) and finished with a titanium nitride coating to improve wear resistance and reduce heat build-up. Laser marking on each shank provides clear size indication while drilling. Their geometry allows drilling without pre-drilling in many materials, and the wooden case keeps the three pieces organized and protected during storage and transport.

Suitable for

• Workshop drilling and general metalworking tasks
• Maintenance and repair operations
• DIY projects involving non-ferrous metals and plastics
• Drilling thin-walled steel sheets

Key specifications

• Quantity: 3 pieces
• Material: High-speed steel (HSS)
• Coating: Titanium nitride (TiN)
• Case type: Wooden case for storage
• Suitable materials: Non-ferrous metals, thin-walled steel sheets, plastics
• Pack weight: 100 g (total)

How to use

Select the appropriate drill bit size for the task, secure the workpiece, and mount the bit securely in the drill chuck. Use steady feed and appropriate drill speed for the material being worked; the TiN coating allows effective drilling with reduced friction and often without pre-drilling pilot holes. Monitor the laser-marked engravings to control depth and hole size, and withdraw occasionally to clear chips and avoid overheating.

Usage recommendations

For best results, use cutting fluid or light lubrication when drilling metals to extend bit life. Start at lower speeds for thin-walled steel to prevent tearing, and increase speed for plastics and non-ferrous metals as appropriate. Store bits dry in the wooden case to prevent corrosion and keep the laser markings legible.
