Drill bit set AWTools AW42219 — 19 pcs, pack weight 440 g

AWTools AW42219 is a 19-piece drill bit set designed for general-purpose drilling in workshops and construction tasks. Manufactured from HSS high speed steel with a 5% cobalt coating, each bit is precision ground to provide reliable performance, efficient chip removal and reduced friction. The pack weight is approximately 440 g, providing a compact, easy-to-store solution for users requiring multiple bit sizes in one set.

Advantages

The HSS material with 5% cobalt increases heat resistance and cutting durability compared to standard high-speed steel, while precision grinding ensures consistent tip geometry and smoother drilling. Low friction and minimal wear extend tool life and reduce the need for frequent replacements. The set’s compact packaging makes it convenient to carry and store in a workshop box or toolbox.

Suitable for

• Drilling alloyed and unalloyed steel
• Drilling cast iron
• Drilling non-ferrous metals such as aluminium and brass
• Drilling PVC and other plastics

Key specifications

• Material: HSS (high speed steel) with 5% cobalt coating

• Set size: 19 pieces
• Pack weight: approximately 440 g
• Intended use: general-purpose drilling in metal and plastic
• Performance characteristics: low friction, minimal wear, increased heat resistance

How to use

Select the correct drill bit size for the hole required and secure workpiece in a vise or with clamps to prevent movement. Fit the chosen AWTools drill bit into the drill chuck and tighten securely. Use appropriate drilling speed for the material: lower speeds for harder metals and higher speeds for softer metals and plastics. Apply steady, moderate pressure and allow the drill to do the cutting; withdraw occasionally to clear chips. Use cutting fluid or coolant when drilling metals to extend tool life and maintain performance.

Usage recommendations

For best results, sharpen or replace bits when cutting performance declines, use cutting fluid on metallic materials, and store the set in a dry place to prevent corrosion. Match drill speed and feed to the material being drilled and avoid excessive lateral force to preserve tip geometry.
