Stepped drill bit Kombi HSS/metric 231319

Step drill bit for precise holes

This step drill bit made of HSS (high-speed steel) is a versatile tool that will be useful both in a professional workshop and in the hands of a DIY enthusiast. Designed for creating through holes and threaded holes in metal, plastic or thin sheets, it offers precision and comfortable work. Its construction allows drilling holes of various diameters with one tool, saving time and space in the toolbox.

Construction and application

The drill bit combines the advantages of a step drill bit and a metric drill bit, making it an ideal choice for a wide range of applications. It has six steps of different diameters, designed for drilling through holes and preparing them for metric threads. This means one tool replaces a set of traditional drill bits. It is particularly useful in sheet metal work, installation work and during the assembly of structural elements. Designed for working with materials up to 5 mm thick (through holes) and 6 mm (threaded holes).

Advantages and benefits

• Versatility: One drill bit for many diameters – saves time and money.
• Precision: Stepped construction ensures clean and accurate holes.
• Durability: Made of chrome-vanadium steel – resistant to wear and damage.
• Wide range of applications: Ideal for metal, plastic, thin sheets and installation work.
• Hole graduation: Allows easy creation of holes for M12, M16, M20, M25, M32 and M40 threads. Hole graduation for through holes: 8.5 – 12.5 – 16.5 – 20.5 – 25.5 – 32.5 – 40.5 mm.
• Right cutting direction: Standard cutting direction ensures intuitive operation.
• Compactness: Replaces a set of traditional drill bits - saves space.

Remember to select the appropriate rotational speed and pressure during drilling to ensure optimal performance and tool durability.
