Drill bit AWTools AW41343 — pack of 10 pieces, weight 28 g

AWTools AW41343 drill bit pack contains ten precision-ground HSS high-speed steel bits with a combined weight of 28 g. Each bit features a cylindrical shank for secure, rapid clamping in standard drill chucks and is manufactured to DIN 338 dimensions. The longer flute length provides extended reach for drilling deeper holes and access to recessed workpieces, while the HSS material delivers durability and heat resistance for repeated use in workshop and industrial settings.

Advantages

These drill bits are made from HSS high-speed steel and are precision ground to ensure straightness and consistent cutting performance. The cylindrical shank design allows quick mounting in chucks without special adapters. Compliance with DIN 338 ensures dimensional accuracy and interchangeability with tools and holders built to the same standard. The extended flute length improves reach for deep or hard-to-access holes, and the overall construction provides reliable performance across a range of common engineering materials.

Suitable for

• Drilling alloyed and unalloyed steel
• Working with gray cast iron
• Processing non-ferrous metals such as aluminum and copper
• Drilling plastics and composite materials
• Workshop repairs, small-scale production and maintenance tasks

Key specifications

• Material: HSS (high-speed steel), precision ground
• Shank type: cylindrical shank for standard drill chucks
• Standards: manufactured to DIN 338 dimensional specifications
• Pack quantity: 10 pieces
• Design: extended flute length for deeper drilling reach
• Weight (total): 28 g

How to use

Select the appropriate bit size from the pack and insert the cylindrical shank fully into the drill chuck, tightening securely. Use suitable cutting speed, feed and cooling for the work material—lower speeds and steady coolant are recommended for harder steels, while higher speeds may be used for non-ferrous metals and plastics. Start drilling with light pressure to establish the pilot, then increase feed steadily. Retract periodically when drilling deep holes to clear chips and reduce heat buildup.

Usage recommendations

For best results, use cutting fluid or coolant when drilling alloyed or hard steels, and ensure the drill is run at speeds appropriate to HSS tooling and the specific material. Inspect bits for wear and replace when cutting edges become dull to maintain hole quality and reduce risk of breakage.
