Drill bit pack AWTools AW41330 — 10 pieces, lightweight general-purpose bits

AWTools AW41330 — 10 pieces, lightweight general-purpose drill bits are a set of precision-ground HSS high-speed steel bits designed for common drilling tasks. The pack contains ten standard-size bits with cylindrical shanks for secure and quick clamping in a drill chuck. These bits are suited to jobs where a longer reach is beneficial, and the overall pack is light and convenient to store or carry for DIY and light professional use.

Advantages

The bits are made of HSS high-speed steel and are precision ground to provide consistent cutting performance and dimensional accuracy. Cylindrical shanks ensure reliable clamping in standard drill chucks and fast bit changes. Compliance with DIN 338 indicates standardized geometry and tolerance for interchangeability and predictable results. Their lightweight pack format simplifies transport and replacement for small projects and on-site tasks.

Suitable for

• Drilling in alloyed and unalloyed steel
• Working with gray cast iron
• Drilling non-ferrous metals such as aluminum and brass
• Making holes in plastics
• Tasks requiring deeper holes or extended reach

Key specifications

• Material: HSS (high-speed steel), precision ground
• Shank type: cylindrical shank for standard chucks
• Pack quantity: 10 pieces
• Standard: DIN 338 compliant (twist drill geometry and tolerances)
• Application range: suitable for steel, cast iron, non-ferrous metals, plastics

How to use

Select a drill speed appropriate for the material being worked: lower speeds for harder steels, higher speeds for non-ferrous metals and plastics. Mount the cylindrical shank securely in the drill chuck and tighten the chuck jaws evenly to avoid runout. Use cutting fluid or lubricant when drilling steel and cast iron to extend bit life and reduce heat. Apply steady axial feed pressure; avoid side loads that can cause breakage. For deeper holes, periodically withdraw the bit to clear chips and reduce clogging.

Usage recommendations

Store the drill bits in a dry place and protect them from impacts to maintain tip geometry. Replace bits that show signs of dulling, chipping, or significant runout to ensure safety and accuracy. When working with hardened or abrasive materials, consider using specialized coated or carbide-tipped drills instead of uncoated HSS for longer life.
