Drill bit pack AWTools AW41400, 10 pcs, total weight 105 g

AWTools AW41400 drill bit pack includes 10 high-speed steel (HSS) twist drills with a combined weight of 105 g. The bits are precision ground and manufactured to DIN 338 specifications for consistent geometry and cutting performance. Each drill has a cylindrical shank for fast and secure clamping in standard chucks, and an extended flute length suited to deeper holes or applications that require extra reach. The set is intended for general drilling tasks in a variety of materials and provides spare bits for uninterrupted work in both handheld drills and drill drivers.

Advantages

The drills are made of HSS high-speed steel and precision ground to maintain sharp cutting edges and dimensional accuracy. Cylindrical shanks enable quick insertion and reliable retention in common three-jaw and keyless chucks. Extended flute length permits drilling of deeper holes while maintaining chip evacuation. Conformance to DIN 338 ensures standardized geometry and interchangeability. The lightweight, compact pack contains multiple sizes for convenient on-site replacement during assembly, renovation or light industrial tasks.

Suitable for

• Drilling alloyed and unalloyed steel
• Working with gray cast iron
• Drilling non-ferrous metals (aluminium, copper, brass)
• Drilling plastics and other synthetic materials
• Use in handheld drills and drill drivers for home improvement or light professional jobs

How to use

Select a drill bit of appropriate diameter and material compatibility for the workpiece. Secure the bit in the drill chuck, ensuring the cylindrical shank is fully seated and tightened to prevent slippage. Use appropriate cutting speed and feed for HSS bits and the material being drilled: lower speeds for harder metals, higher speeds for softer metals and plastics. Apply cutting fluid or coolant when drilling steel or alloyed metals to reduce heat and prolong bit life. Clear chips periodically from the hole to maintain penetration and prevent overheating.

Usage recommendations

For optimal performance and tool life, start with a pilot hole when drilling large diameters, maintain firm, steady pressure, and use cutting fluid for ferrous materials. Inspect bits for wear or damage before reuse and replace worn bits from the pack to ensure consistent drilling quality.
