Drill bit set AWTools AW42001 — 13 pieces, pack weight 120 g

The AWTools AW42001 drill bit set contains 13 precision ground HSS-G M2 high-speed steel bits supplied in a compact plastic case. Each bit features two cutting edges, black oxide finish and a 135° centering point angle designed to reduce walking and improve positioning. The set is specified for general drilling in alloyed and unalloyed steel, grey cast iron, non-ferrous metals and plastics, and is intended for routine wood, metal and plastic work where compatible. Total pack weight is approximately 120 g, making the set convenient to store and transport.

Advantages

The use of HSS-G M2 high-speed steel and precision grinding provides high wear resistance and a reduced risk of breakage under normal operating conditions. The black oxide coating helps resist corrosion and improves chip evacuation by reducing friction. The 135° centering point improves accuracy on flat surfaces and reduces the need for a pilot hole when positioning the bit. The included plastic case keeps bits organized and protected during storage and transport.

Suitable for

• Drilling alloyed and unalloyed steel
• Working with grey cast iron
• Drilling non-ferrous metals such as aluminium and copper
• Routine drilling in plastics
• Hobby, maintenance and light professional workshop tasks

How to use

Select the correct drill bit size for the material and hole required. Secure the workpiece to prevent movement and mount the bit correctly in the drill chuck with sufficient clamping length. Use appropriate drill speed and feed for HSS bits: lower speeds for hard metals and higher speeds for softer materials and plastics, with moderate feed to avoid overheating. Apply cutting fluid or lubricant when drilling steels or cast iron to extend bit life and improve chip removal. After use, clean chips from the flutes and store bits in the plastic case to protect the cutting edges.

Usage recommendations

For best results, match drill speed and feed to the material being drilled, use cutting fluid on ferrous metals, and avoid excessive side load to minimize wear and risk of breakage. Regularly inspect bits for bluntness and replace worn bits to maintain drilling accuracy and safety.
