Drill bit pack AWTools AW42050 — 10 pcs, general-purpose metal/wood drilling

AWTools AW42050 — a pack of 10 general-purpose drill bits made of HSS-Co high-speed steel with 5% cobalt, precision ground with two cutting edges and a 135° centering point angle. The set is supplied in a storage case and is designed for handheld drills and drill presses to perform standard drilling tasks in metal, wood and plastics. These drill bits combine wear resistance and thermal stability for repeated hole-making in common workshop and construction environments.

Advantages

The HSS-Co composition with 5% cobalt improves red-hardness and extends bit life under higher cutting temperatures compared with conventional HSS. Precision grinding and two-cutting-edge geometry ensure accurate centring and stable cutting performance, while the 135° point angle reduces walking on the workpiece surface. Supplied in a compact case, the pack keeps bits organised and protected for transport and storage.

Suitable for

• Drilling alloyed and unalloyed steels
• Drilling grey cast iron
• Working with non-ferrous metals such as aluminium and copper
• Drilling plastics and general workshop wood tasks
• Use with handheld drills and drill presses for DIY, repair and maintenance

How to use

Secure the appropriate drill bit in the chuck of a handheld drill or drill press, ensuring correct seating and tight clamping. Choose a drilling speed and feed rate suitable for the work material — lower speeds for harder steels, higher speeds for non-ferrous metals and plastics. Apply steady pressure and allow the bit to do the cutting; periodically withdraw the bit to clear chips and reduce heat buildup. For best results when drilling steel, use cutting fluid or coolant to extend tool life and maintain hole quality.

Usage recommendations

Use personal protective equipment such as safety glasses and gloves. Match drill speed and lubrication to the material being drilled: use coolant or cutting oil for alloyed steels, moderate speeds for cast iron, and higher speeds for aluminium and plastics. Store the bits in the supplied case to prevent damage and corrosion.
