Drill bit pack AWTools AW41361 — twist drill bits, pack of 10, 33 g total

AWTools AW41361 drill bit pack contains 10 precision-ground HSS twist drill bits with a total weight of 33 g. The bits feature cylindrical shanks and conform to DIN 338 dimensions, making them compatible with standard handheld drills and drill presses. Manufactured from high-speed steel, these drill bits are designed for general-purpose metal and plastic drilling where reliable cutting performance and longer reach are required.

Advantages

The set provides a consistent cutting geometry due to precision grinding, which helps maintain accurate hole diameter and straightness. Cylindrical shanks ensure quick and secure clamping in common chucks. High-speed steel material delivers good wear resistance and heat tolerance for routine and repetitive drilling tasks. The assortment of ten pieces offers immediate spare capacity for maintenance, light construction and hobby projects.

Suitable for

• Drilling in alloyed and unalloyed steel
• Drilling gray cast iron
• Drilling non-ferrous metals such as aluminum and brass
• Drilling plastics and composite materials
• Use with handheld drills and drill presses

Key specifications

• Material: high-speed steel (HSS), precision ground
• Shank type: cylindrical shank for standard chucks
• Standards: manufactured to DIN 338 dimensions
• Pack contents: 10 twist drill bits
• Total pack weight: 33 g
• Application: general-purpose metal and plastic drilling; suitable for deeper holes and extended reach

How to use

Select the appropriate drill bit size for the required hole diameter and clamp the cylindrical shank securely in the drill chuck. Use appropriate cutting speed and feed rate for the workpiece material—lower speeds for harder steels, higher speeds for non-ferrous metals and plastics. Apply steady pressure and ensure correct alignment to maintain hole straightness; for deeper holes use coolant or intermittent peck drilling to evacuate chips and control temperature. After use, clean chips from the flutes and store the bits in a dry place.

Usage recommendations

For best results, use cutting fluid when drilling alloyed steels and gray cast iron to extend tool life. When drilling plastics, reduce speed and minimize thrust to avoid melting. Regularly inspect bit tips for wear and regrind or replace when accuracy degrades.
