Drill bit AWTools AW41415 – pack of 5, AW41415 model, weight 35 g

AWTools AW41415 drill bit pack contains five identical HSS high-speed steel bits with precision ground flutes and a cylindrical shank. Each bit is designed to meet DIN 338 dimensional and geometric standards, offering consistent cutting performance and improved straightness for general drilling tasks. The set is supplied as five pieces with a combined weight of 35 g and is intended as a replacement or spare set for handheld and bench drills when this specific AW41415 geometry and reach are required.

Advantages

The bits are made of HSS high-speed steel that retains hardness at elevated cutting temperatures, enabling effective drilling in a variety of materials. Precision ground flutes and a longer cutting length provide stable chip evacuation and better guidance when drilling deeper holes. The cylindrical shank simplifies clamping in standard drill chucks and helps maintain concentricity during operation. Compliance with DIN 338 ensures compatibility with common diameter and point-angle expectations for twist drills.

Suitable for

• Drilling alloyed and unalloyed steel
• Drilling gray cast iron
• Drilling non-ferrous metals (aluminum, brass, copper)
• Drilling plastics and composite materials
• General workshop, maintenance, and industrial drilling tasks

Key specifications

• Material: HSS (high-speed steel), precision ground
• Shank type: cylindrical shank for standard chucks
• Quantity in pack: 5 identical drill bits
• Total pack weight: 35 g
• Standard: manufactured to DIN 338 dimensional and geometric requirements
• Design: long flute length for deeper drilling reach

How to use

Select a drill speed and feed appropriate for the workpiece material and drill diameter. Secure the cylindrical shank firmly in the drill chuck to ensure concentric rotation. Use cutting fluid or coolant when drilling steels and other metals to extend tool life and improve chip evacuation. Start drilling at a moderate speed to establish the hole, then apply steady pressure without forcing the bit. Clear chips periodically when drilling deep holes to prevent clogging and overheating.

Usage recommendations

For best results, match drilling speed and lubricant to the material: lower speeds with cutting fluid for steels, medium speeds for non-ferrous metals, and higher speeds for plastics while avoiding excessive heat. Inspect bits for wear or chipping before use and replace if cutting performance deteriorates.
