Drill bit pack AWTools AW41870 — pack of 10, standard twist drill bits

AWTools AW41870 — pack of 10 standard twist drill bits is a 10-piece set of general-purpose drills designed for use with compatible handheld and stationary drills. Manufactured from HSS-G M2 high-speed steel and precision ground, each bit features two cutting edges and a black oxide finish. The bits are supplied in a case and have a centering point with a 135° point angle, providing accurate starts and stable drilling performance across a range of common workshop materials.

Advantages

The HSS-G M2 construction offers high wear resistance and consistent hardness for extended tool life. Precision grinding and two cutting edges deliver clean holes and reliable chip removal, while the black oxide surface improves corrosion resistance and reduces friction. The 135° centering point reduces wandering at the start of drilling, lowering the risk of breakage and improving accuracy when working with both handheld and stationary drills.

Suitable for

• Drilling alloyed and unalloyed steels
• Working with grey cast iron
• Drilling non-ferrous metals such as aluminium and copper
• Drilling plastic components
• General workshop and construction tasks requiring standard twist bits

Key specifications

• Material: HSS-G M2 high-speed steel
• Finish: black oxide
• Cutting geometry: precision ground, two cutting edges
• Point angle: 135° centering point
• Pack size: 10 pieces supplied in a case

How to use

Select the appropriate drill bit size for the required hole and secure it tightly in the drill chuck. Use moderate feed pressure and appropriate rotational speed for the material being drilled—lower speeds for harder steels and higher speeds for non-ferrous metals and plastics. Ensure the workpiece is clamped or otherwise secured. Apply cutting fluid or lubricant when drilling steels and alloys to improve chip evacuation and reduce heat build-up. Clear chips frequently and allow the bit to cool if drilling multiple holes in succession.

Usage recommendations

For best results, match drill speed and feed to the material: reduce speed for hardened or alloyed steels and use cutting fluid. Store bits in the supplied case to protect cutting edges and maintain accuracy. Replace worn bits to avoid oversized holes and poor finish.
