## Summary description

Tvardy step drill bit in HSS M2 steel with TiAlN coating, cutting range 4–32 mm and overall length 100 mm. Designed for progressive hole drilling in sheet metal and thin materials, it provides multiple diameter steps in a single tool, reducing tool changes. Suitable for metalworking, electrical installation and fabrication tasks that require clean, incremental hole sizes.

## Long description

Tvardy HSS M2 TiAlN step drill bit with a cutting range of 4–32 mm and an overall length of 100 mm is designed to drill progressively larger holes in sheet metal and other thin materials. The tool integrates multiple diameter steps on a single flute, allowing users to create incrementally larger holes without changing bits. Constructed from high-speed steel M2 and finished with a titanium aluminium nitride (TiAlN) coating, the drill bit is intended for repeated use in metalworking and electrical installation tasks that require clean edges and accurate step diameters.
Advantages
The HSS M2 substrate offers a combination of hardness and toughness appropriate for drilling thin steel and non-ferrous metals, while the TiAlN coating increases surface hardness and heat resistance to extend tool life under higher cutting temperatures. The stepped geometry eliminates frequent bit changes and simplifies the process of enlarging hole diameters. The 100 mm overall length provides reach for through-sheet or slightly recessed applications, and the 4–32 mm range covers common hole sizes used in installations and fabrications.
Suitable for
 Drilling progressive holes in sheet metal and thin steel
 Create multiple stepped diameters for cable glands and conduit entries
 Electrical installation and panel work where different hole sizes are required
 Light fabrication and maintenance tasks on non-ferrous metals and plastics
Key specifications
 Material: High-speed steel (HSS M2)
 Coating: Titanium aluminium nitride (TiAlN)
 Cutting range: 4–32 mm (stepped diameters)
 Overall length: 100 mm
 Geometry: Multi-step flute for progressive hole enlargement
How to use
Secure the workpiece and select appropriate cutting speed for the material being drilled; lower speeds are recommended for harder metals. Mount the step drill bit in a keyed or keyless chuck ensuring concentricity. Begin drilling with light pressure at the smallest step, allowing the tool to establish the hole before advancing to larger steps. Apply cutting fluid or lubricant when working with steel to reduce heat and improve finish. Withdraw the bit periodically to clear chips and prevent clogging of the stepped flutes.
Usage recommendations
For longest tool life, use moderate feed rates and avoid excessive dwell at larger diameters. Choose lower RPM for stainless and hardened steels, and apply cutting fluid for steelwork. Inspect the stepped edges for wear and recoat or replace the bit when the finish quality or dimensional accuracy degrades.
