Drill bit AWTools AW41830 — pack of 10

AWTools AW41830 — pack of 10 high-speed steel drill bits supplied in a compact case. Each bit is made from HSS-G M2 precision-ground material with a black oxide finish and two cutting edges. The bits feature a centering point with a 135° point angle for accurate starts and are intended for general-purpose drilling tasks and replacement use in workshops, construction sites and maintenance operations.

Advantages

Manufactured from HSS-G M2 high-speed steel and precision ground, these drill bits offer high wear resistance and consistent cutting performance. The black oxide coating reduces friction and improves corrosion resistance, while the two-cutting-edge geometry and 135° centering point lower the risk of walking and make positioning easier. Supplied as a pack of 10 in a case, the set provides multiple identical replacement bits for continuous work and reduced downtime.

Suitable for

• Drilling alloyed and unalloyed steels
• Drilling grey cast iron
• Drilling non-ferrous metals (aluminum, copper, brass)
• Drilling plastics and general workshop materials
• Use in maintenance, construction, and production where identical bits are needed

Key specifications

How to use

Secure the drill bit in a compatible drill chuck, ensuring concentric clamping and correct seating. Select appropriate spindle speed and feed for the workpiece material—lower speeds for harder steels, higher speeds for non-ferrous metals and plastics. Use cutting lubricant when drilling steel or alloyed materials to extend tool life and reduce heat. Apply steady, even pressure; withdraw occasionally to clear chips when drilling deep holes. After use, store the bits in their case to protect the cutting edges and coating.

Usage recommendations

For best results when drilling steel and cast iron, use cutting fluid and moderate drilling speeds to reduce wear. For non-ferrous metals and plastics, higher speeds and light feeds are suitable; avoid excessive pressure to prevent melting or grabbing. Inspect bits for wear or chipping before reuse and replace damaged bits to maintain hole quality and reduce the risk of breakage.
