Drill bit set AWTools AW42400 — 6 pieces, pack weight 170 g

AWTools AW42400 — 6-piece drill bit set designed for general drilling tasks in home repair, workshop and light construction. The set contains six HSS bits with titanium nitride (TiN) coating that reduces friction and heat during drilling. Each bit features a 3-tip geometry for smoother cutting and improved control when working with metals and plastics. The round shank fits standard three-jaw chucks, making the set compatible with most handheld and bench drills.

Advantages

The high-speed steel construction provides wear resistance and maintains cutting performance at elevated temperatures. TiN coating lowers friction, extends tool life and improves surface finish of drilled holes. The 3-tip design helps reduce burr formation and minimizes walking at drill start, which leads to cleaner and more accurate holes. Lightweight and compact, the pack is easy to store and carry for everyday tasks.

Suitable for

• Drilling holes in alloy and carbon steel
• Working with gray cast iron
• Drilling non-ferrous metals such as aluminum and brass
• Creating holes in plastics and composite materials
• General-purpose home repairs and workshop tasks

Key specifications

• Material: high-speed steel (HSS)
• Coating: titanium nitride (TiN)
• Tip geometry: 3-tip design for smoother cutting
• Shank type: round shank for three-jaw chucks
• Quantity: 6 pieces per pack
• Pack weight: 170 g
• Suitable materials: alloy and carbon steel, gray cast iron, non-ferrous metals, plastics

How to use

Select the appropriate drill bit size for the material and hole diameter required. Secure the round shank in a compatible three-jaw chuck and tighten firmly. Begin drilling at low speed to establish the hole, then increase speed as needed while applying steady, moderate pressure. For metal work, use cutting fluid or oil to reduce heat and extend bit life. After drilling, remove burrs or perform light countersinking if a flush finish is required.

Usage recommendations

Use appropriate personal protective equipment such as safety glasses and gloves. Match drill speed and feed to the material: lower speeds for harder steels, higher speeds for softer non-ferrous metals and plastics. Regularly clear chips from the hole and reapply coolant when drilling thicker sections to avoid overheating and reduce wear.
