Drill bit set AWTools AW41203 — 19-piece pack, total weight 550 g

AWTools AW41203 — 19-piece drill bit set in a compact plastic case, total weight 550 g. The set contains a selection of precision-ground HSS (high speed steel) drill bits hardened for general workshop and home use. Bits are designed for standard drilling tasks in alloyed and unalloyed steel, cast iron, non-ferrous metals and PVC plastic, providing reliable performance for repair, maintenance and DIY projects.

Advantages

The drill bits are made of hardened HSS high speed steel and precision ground to ensure consistent cutting geometry and efficient chip removal. Low friction surfaces reduce wear and help maintain cutting performance over repeated use. The assortment covers multiple common diameters, stored in a single plastic case that keeps bits organized and protected during transport and storage.

Suitable for

• General-purpose drilling in workshops and home garages
• Repair and maintenance tasks on steel, cast iron and non-ferrous metals
• DIY projects involving metal and PVC plastic
• Compact tool kits and portable drilling sets for field use

Key specifications

• Material: HSS (high speed steel), hardened
• Number of pieces: 19
• Packaging: plastic case for storage and transport
• Total weight: 550 g (packaged)
• Finish: precision ground cutting edges for efficient chip removal
• Recommended materials: alloyed and unalloyed steel, cast iron, non‑ferrous metals, PVC plastic

How to use

Select the appropriate drill bit size for the required hole diameter and secure it in the drill chuck with proper centering. Use appropriate cutting speed and feed for the material being drilled: lower speeds for harder metals and higher speeds for softer non‑ferrous metals and plastics. Apply steady pressure without forcing the bit; use cutting fluid or lubricant when drilling steel and cast iron to extend bit life and improve chip evacuation. Clear chips regularly and allow the bit to cool if it becomes hot during prolonged use.

Usage recommendations

For best results, match drill speed and feed to the material, use cutting fluid on steel and cast iron, and store bits in the supplied plastic case to protect the precision-ground edges. Replace worn or chipped bits to maintain hole quality and safety.
