Drill Bit set AWTools AW41413 — 5 pieces, pack weight 305 g

AWTools AW41413 — a set of five precision ground HSS drill bits supplied as a compact pack weighing 305 g. These cylindrical-shank bits are manufactured to DIN 338 tolerances and provide extended reach for drilling deeper holes. Made of high-speed steel, they are engineered for use with standard hand drills and drill presses in workshop, maintenance and industrial environments where reliable metal and plastic drilling is required.

Advantages

The precision ground HSS cutting edges deliver consistent chip formation and long cutting life under normal operating speeds. A cylindrical shank enables fast and secure clamping in standard chucks, reducing setup time. The longer flute length and reinforced design make this set suitable for deeper hole drilling while maintaining straightness and concentricity. Conformance to DIN 338 ensures dimensional and performance consistency across pieces in the set.

Suitable for

• Drilling alloyed and unalloyed steels
• Working with gray cast iron
• Drilling non-ferrous metals such as aluminum and copper
• Drilling plastics and composite materials
• Workshop, maintenance and light industrial drilling tasks

Key specifications

• Material: High-speed steel (HSS), precision ground
• Shank type: Cylindrical shank for standard chucks
• Design standard: Manufactured to DIN 338 dimensional tolerances
• Set composition: 5 drill bits supplied as a multi-piece pack
• Pack weight: 305 g (total)
• Intended use: Extended flute length for deeper hole drilling

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 recommended cutting speeds and appropriate cutting fluid when drilling metals to extend tool life and improve surface finish. For plastics, reduce speed and avoid excessive feed to prevent melting. Maintain firm support of the workpiece and use a center punch or pilot hole when needed to ensure accurate hole placement.

Usage recommendations

For best results when drilling metals, apply suitable cutting lubricant and moderate feed rates. When drilling deeper holes, periodically withdraw the bit to clear chips and prevent clogging. Inspect bits for wear or chipping and replace individual bits from the set when cutting performance deteriorates.
