Drill bit set AWTools AW42325 — 25 pieces, pack weight 1.14 kg

AWTools AW42325 drill bit set contains 25 pieces made of HSS (high speed steel) with a titanium nitride (TiN) coating, supplied in a metal case and weighing 1.14 kg per pack. The set is precision ground to deliver consistent cutting performance and easier chip evacuation, and is designed for general drilling tasks in workshop, construction and maintenance environments.

Advantages

The TiN coating reduces friction and increases surface hardness, which helps minimise wear during repeated drilling operations. Precision grinding ensures accurate point geometry for stable drilling and improved centring, while the HSS material retains hardness at elevated temperatures. Supplied in a durable metal case, the set is organised for storage and transport.

Suitable for

• Drilling alloyed and unalloyed steel
• Working with cast iron
• Drilling non‑ferrous metals such as aluminium and brass
• Making holes in PVC and other plastics

Key specifications

• Quantity: 25 drill bits per pack
• Material: HSS (high speed steel)
• Coating: Titanium nitride (TiN)
• Finish: Precision ground flutes and point geometry
• Packaging: Metal storage case
• Pack weight: 1.14 kg

How to use

Select the appropriate drill bit size for the required hole diameter and secure it in a compatible drill chuck. Use steady feed and appropriate spindle speed for the work material: lower speeds for harder metals and higher speeds for softer metals and plastics. Apply cutting fluid when drilling steel or other metals to reduce heat and extend tool life. Maintain perpendicular alignment at the start of drilling to ensure correct centring and feed steadily without excessive side load.

Usage recommendations

For best results, store the drill bits in their metal case to protect the TiN coating and edges. Replace worn bits to avoid poor hole quality and increased load on the drill motor. When drilling plastics, use higher speeds and reduced feed force to prevent melting. For steel and cast iron, use appropriate coolant and moderate speeds to preserve HSS hardness and prolong service life.
