Bosch HSS-R Metal Drill Bit Set, 1–13 mm, 25 Pieces

The Bosch HSS-R Metal Drill Bit Set, 1–13 mm, 25 pieces, is a 25-piece assortment of rolled high-speed steel drill bits designed for drilling holes in metal. It offers a practical solution for users who need reliable cutting performance across a range of workpiece tasks. The bits are built to handle the demands of standard metal fabrication and assembly preparation, and the broad size range means the right bit is on hand for different fasteners or general hole-making. For a regular workshop, having this material capability in a single set is a useful resource.

Having a continuous sequence of sizes removes the need to make do with a bit that is not properly proportioned for a specific fastener. Operators can drill closely matched clearance holes or widen existing openings gradually without switching between different tool lines. Keeping a dedicated set avoids the frequent interruption of sourcing individual pieces during an active project. Uniformly manufactured components deliver consistent cutting behaviour regardless of which diameter is used. The set works as a cohesive toolkit for varied installation requirements.

• 1 mm to 13 mm overall size range covers standard metric clearance hole requirements.
• 0.5 mm stepping increments enable controlled, gradual hole expansion in metal sheets.
• 1310 g total product weight reflects the substantial physical mass of the complete assortment.
• Rolled high-speed steel (HSS-R) provides the necessary hardness for penetrating metal workpieces.
• Includes precise intermediate dimensions such as 10.5 mm, 11.5 mm, and 12.5 mm for exact fastener matching.
