Drill bit set AWTools AW42003 — 19 pieces, pack weight 450 g

AWTools AW42003 — 19 pieces, pack weight 450 g is a compact drill bit set designed for general-purpose drilling in workshop and DIY environments. The set contains 19 precision-ground HSS-G M2 high-speed steel bits with two cutting edges and a black oxide finish, supplied in a molded plastic case for neat storage and transport. Each bit features a centering point with a 135° point angle to improve accuracy when starting holes and to reduce walking on the workpiece.

Advantages

The AWTools AW42003 set is made from HSS-G M2 high-speed steel offering high wear resistance and a low risk of breakage during standard drilling operations. Precision grinding and two-cutting-edge geometry provide consistent cutting performance and smoother hole quality. The black oxide coating increases surface durability and helps reduce friction and corrosion. Supplied in a plastic case, the set is organized for quick selection and safe transport.

Suitable for

• Drilling alloyed and unalloyed steels
• Working with grey cast iron
• Drilling non-ferrous metals such as aluminium and copper
• Creating holes in plastics
• General workshop and DIY repair tasks

How to use

Select the appropriate drill bit size from the plastic case and secure it in a suitable drill chuck or driver. Use appropriate cutting speeds and feed rates for the material being drilled; lower speeds for harder metals and higher speeds for softer non-ferrous metals and plastics. Apply steady pressure and keep the drill perpendicular to the workpiece to ensure accurate holes. For deeper holes or tougher materials, withdraw the bit periodically to clear chips and prevent overheating. Use cutting fluid or coolant when drilling alloyed steels to extend bit life.

Usage recommendations

For best results, clamp the workpiece securely, start with a pilot hole if required, and match drill speed and lubrication to the material. Store the bits in their plastic case after cooling to maintain organization and protect the cutting edges.
