Drill bit set AWTools AW40998 — 3 pcs, pack weight 375 g

The AWTools AW40998 drill bit set contains three high-speed steel bits coated with titanium nitride (TiN) and presented in a wooden case. Designed for use with compatible drills, the set is intended for general drilling tasks in a variety of materials. Laser-engraved size marks on each bit allow quick identification of the required diameter during work, while the TiN coating reduces friction and increases wear resistance for longer service life.

Advantages

Bits made from HSS high-speed steel provide hardness and heat resistance suitable for repeated drilling operations. The titanium nitride coating lowers friction, helps maintain cutting performance and reduces edge wear. Laser-engraved size markings ensure accurate size control without the need for additional measuring tools. The wooden case keeps the three-piece set organized and protected during storage and transport.

Suitable for

• Drilling holes in plastic components
• Working with aluminum and copper sheet
• Drilling thin stainless steel and other sheet metals
• Home and workshop repair or assembly tasks
• Keeping a small set of replacement or spare bits for on-site use

Key specifications

• Material: HSS (high-speed steel)
• Coating: titanium nitride (TiN)
• Pack contents: 3 drill bits
• Pack weight: 375 g (including wooden case)
• Marking: laser-engraved size markings on each bit
• Storage: wooden case

How to use

Select the drill bit with the required diameter by checking the laser-engraved marking, secure the bit in the drill chuck and tighten properly. Use appropriate drill speed and feed for the work material—lower speeds for stainless steel and higher speeds for plastics and softer non-ferrous metals. Apply steady pressure, avoid excessive heat build-up, and periodically withdraw the bit to clear chips when drilling sheet metals. After use, allow the bit to cool if necessary and store it in the wooden case to protect the cutting edges.

Usage recommendations

For best results when drilling metals, use cutting lubricant on stainless steel and harder alloys to reduce heat and extend bit life; for plastics and non-ferrous metals, a dry cut at moderate speed is often sufficient. Inspect bits regularly for wear and replace when cutting edges are rounded or damaged.
