Drill bit set AWTools AW41204 — 19 pieces, total weight 575 g

AWTools AW41204 — 19-piece drill bit set supplied in a compact metal case, total weight 575 g. The set includes a range of commonly used diameters made of hardened HSS high-speed steel with precision ground flutes. Designed for general-purpose drilling tasks, these bits are suitable for use with standard hand drills and drill presses for work on steels, cast iron, non-ferrous metals and PVC plastic. The metal case keeps bits organised and protects them during storage and transport.

Advantages

Drill bits are manufactured from hardened HSS high-speed steel and precision ground for consistent hole geometry and efficient chip evacuation. The material and surface finish reduce friction and wear, improving durability and cutting performance. Supplied in a metal case, the set is compact and convenient to carry between job sites or to store in a workshop. The selection of sizes covers common drilling needs for maintenance, repair and light construction tasks.

Suitable for

• Drilling alloyed and unalloyed steel
• Drilling cast iron
• Drilling non-ferrous metals (aluminium, brass, copper)
• Drilling PVC and other plastic materials
• General-purpose home, workshop and on-site repair tasks

Key specifications

• Piece count: 19 drill bits
• Material: HSS (high-speed steel), hardened
• Manufacturing: precision ground flutes for improved chip removal
• Finish: low-friction surface for reduced wear
• Case: compact metal storage case
• Total weight (packaged): 575 g

How to use

Select a drill bit size appropriate for the hole diameter required and insert it securely into the drill chuck. Use an appropriate drill speed for the material being worked: lower speeds for harder metals and higher speeds for softer metals and plastics. Apply steady, moderate feed pressure and allow the bit to cut without excessive force. For drilling metals, use cutting fluid or lubricant to reduce heat and extend bit life. Clear chips regularly to maintain efficient cutting and avoid clogging the flutes.

Usage recommendations

For best results when drilling metals, clamp workpieces securely and use a center punch to mark drilling points. Match drill speed and feed rate to the material: slow and steady for hard steels, faster for aluminium and plastics. Store the drill bits in the metal case to prevent damage and corrosion; inspect bits for wear or bluntness and re-sharpen or replace as needed.
