Drill bit set AWTools AW42213 — 13-piece pack, 260 g total weight

AWTools AW42213 — 13-piece drill bit set weighing 260 g in total. The set includes a range of HSS (high speed steel) drill bits with 5% cobalt coating, precision ground for efficient cutting and easy chip evacuation. Designed for general drilling tasks, these bits are appropriate for use in alloyed and unalloyed steel, cast iron, non-ferrous metals and PVC plastic. Supplied as a compact pack, the set is suitable for hobbyists, handymen and light professional work.

Advantages

The HSS construction with 5% cobalt increases heat resistance and extends tool life during intermittent and light continuous drilling. Precision grinding ensures consistent tip geometry for accurate hole positioning and reduced walking. Low-friction coating reduces wear and helps maintain cutting performance over multiple uses. The compact 13-piece pack provides a practical selection of sizes for common drilling operations while remaining easy to store and transport.

Suitable for

• Drilling holes in alloyed and unalloyed steel
• Working with cast iron components
• Drilling non-ferrous metals such as aluminium and brass
• Making holes in PVC and other plastics
• General workshop tasks for hobbyists and maintenance professionals

Key specifications

• Set size: 13 pieces
• Total weight: 260 g
• Material: High Speed Steel (HSS) with 5% cobalt
• Tip finish: Precision ground for accurate cutting and chip removal
• Coating: Low-friction surface treatment to reduce wear
• Suitable work materials: Alloyed and unalloyed steel, cast iron, non-ferrous metals, PVC plastic

How to use

Select the drill bit size appropriate for the required hole diameter and secure the workpiece to prevent movement. Use a drill press or handheld drill with a compatible chuck, and set a suitable speed for the material: lower speeds for harder metals, higher speeds for plastics and softer non-ferrous metals. Apply moderate, steady pressure and allow the drill to cut without forcing; withdraw occasionally to clear chips and reduce heat build-up. Coolant or cutting fluid can be used when drilling harder steels or during extended operations to prolong bit life.

Usage recommendations

For best results, start with a small pilot hole when drilling large diameters in metal, maintain appropriate drilling speeds, and use cutting fluid on harder materials. Store the set in a dry place and inspect bits for wear before use; replace damaged or excessively worn bits to ensure safe and accurate drilling.
