Tvardy step drill bit made of HSS M2 with TiAlN coating, covering a diameter range of 4–20 mm. Designed for progressive drilling of sheet materials and thin metals, it provides multiple hole diameters with a single tool. Typical uses include sheet metal fabrication, electrical panels, plumbing and general workshop tasks where stepped holes are required. Pack quantity: 200 pieces.

## Long description

Tvardy HSS M2 TiAlN step drill 4–20 mm (200) is a set of step drill bits manufactured from high-speed steel (HSS M2) with a titanium aluminum nitride (TiAlN) coating. Each bit covers a diameter range of 4 to 20 mm in stepped increments, allowing progressive enlargement of holes in sheet materials and thin metals with a single tool. The set is intended for repetitive tasks in fabrication, maintenance and workshop environments and is supplied in a pack quantity of 200 pieces.
Advantages
The HSS M2 substrate provides high hardness and heat resistance for extended cutting life, while the TiAlN coating reduces friction and improves wear resistance during prolonged use. Using step drill bits eliminates the need to change multiple twist drills to reach different diameters, saving time and reducing tool changes. The stepped geometry creates clean, deburred holes in thin materials and helps maintain concentricity when enlarging existing holes.
Suitable for
 Progressive drilling in sheet metal and thin steel
 Electrical panels and enclosure work
 Plumbing and HVAC installations where multiple hole sizes are required
 General workshop tasks and maintenance operations
Key specifications
 Material: high-speed steel (HSS M2) with TiAlN coating
 Diameter range: 4–20 mm (stepped increments)
 Type: step drill bit
 Suitable materials: sheet metal, thin steel, non-ferrous metals and some plastics
 Pack quantity: 200 pieces
How to use
Secure the workpiece and mark the drilling point. Mount the step drill bit in a drill with an appropriate chuck and run at recommended speeds for the material being drilled (lower speeds for harder metals). Start drilling with light pressure, allowing the stepped geometry to cut progressively through the material. Withdraw the bit periodically to clear chips and reduce heat buildup. For larger steps, finish with the final step until the desired diameter is reached.
Usage recommendations
Apply cutting fluid when drilling steel or other hard metals to extend tool life and improve hole quality. Use steady feed and avoid excessive side loads to prevent chipping the cutting edges. For thin or flexible sheets, support the workpiece to avoid deformation during drilling.
