Drilling instead of guessing.
a+s HSS twist drill set 1-10.0 mm, 19 pieces.
The A+S HSS twist drill set (1–10.0 mm, 19-piece) covers all common diameters in 0.5 mm increments, making it a universal tool set for precise drilling in steel, aluminum, and non-ferrous metals. The ground HSS drills with stepped tips center cleanly, start smoothly, and ensure controlled chip removal – ideal for workshops, service vehicles, and assembly work.
A cleverly designed stepped top.
Precise centering, less effort required.
The stepped tip combines a smaller pilot hole with the actual drill diameter. The first step acts like an integrated centering drill, reducing wandering on smooth or slightly curved surfaces. Simultaneously, material is removed in stages, requiring less feed force and allowing the drill to run cooler. The result is cleaner hole edges and a longer tool life.
Suitcases & Organization.
Everything in place – from 1.0 to 10.0 mm.
The drill bits are housed in a robust ABS plastic box designed for daily workshop use. The compartments are sorted by diameter, allowing each drill bit to be quickly found and safely stored after use. The sturdy box protects the drill bits from damage during operation, in tool carts, or in service vehicles.
- Robust ABS plastic box, dimensionally stable and impact resistant
- Clear arrangement of diameters from 1.0–10.0 mm
- Ideal for workshops, service cases and mobile use
- Easy relocation and re-sorting of the drill bits
Advantages & Features.
Well-designed set for metalworking.
This 19-piece set is specifically designed for metalworking. The fully ground HSS drill bits with stepped tips combine smooth running with high dimensional accuracy. The 0.5 mm increments from 1.0 to 10.0 mm cover the common core and through-hole drilling applications in mechanical engineering, maintenance, and crafts.
- 19-piece assortment from 1.0–10.0 mm in 0.5 mm increments
- HSS, fully ground for precise drilling
- Stepped tip for safe drilling without additional centering tools
- Suitable for steel, aluminum, copper alloys and many plastics
- Robust ABS box for use in workshops and service vehicles

Areas of application.
The A+S HSS twist drill set (1–10 mm) is suitable for classic metalworking tasks as well as repair and assembly work. The finely graduated diameters allow for the production of both core holes for threads and precise through holes.
- Drilling work in steel, aluminium and non-ferrous metals
- Core drilling for threads in the range M3–M10
- Assembly and repair work in mechanical and plant engineering
- Use in the workshop, on construction sites and in service vehicles

Precision thread cutting with a+s
Thread cutting is one of the most important tasks in metalworking. With precise HSSG taps according to DIN 352, dies according to DIN EN 22568, and matching twist drills according to DIN 338, internal and external threads can be cleanly produced or repaired – quickly, reliably, and with professional dimensional accuracy. The appropriate drill set provides the correct pilot and through holes.
