## Long description

Silver Step Drill Bit 4–39 mm HSS model 03222 is a single-piece, stepped HSS drill designed to make progressive hole enlargement efficient in sheet metal, plastics and non-ferrous materials. The stepped profile covers diameters from 4 mm up to 39 mm, allowing the operator to produce multiple hole sizes with one tool. The geometry and HSS construction provide durability and consistent cutting action when used in hand drills and drill presses for general fabrication tasks.
Advantages
This HSS step drill delivers consecutive hole sizes without tool changes, reducing setup time and improving workflow. Its single-piece design maintains concentricity across steps, ensuring more accurate holes. The HSS material offers a balance of hardness and toughness suitable for cutting thin metal sheets and softer materials, while the stepped profile helps deburr and chamfer holes during drilling.
Suitable for
Enlarging or creating holes in sheet metal
Drilling in plastic panels and PVC materials
Working with non-ferrous metals such as aluminium and brass
Electrical panel and conduit hole preparation
HVAC ducts and general metal fabrication
Key specifications
Material: High Speed Steel (HSS)
Step range: 4 mm to 39 mm
Design: Single-piece stepped profile
Compatibility: Suitable for hand drills and drill presses
Application: Progressive hole enlargement in thin materials
How to use
Select the step corresponding to the target diameter and secure the workpiece to prevent movement. Use a drill with stable speed control, start at low speed to establish the pilot cut, and increase speed as required for smooth cutting. Apply steady, even pressure and withdraw occasionally to clear chips. For metal work, use cutting fluid to reduce heat and extend tool life. Progress through steps sequentially if enlarging an existing hole to avoid excessive load on a single pass.
Usage recommendations
For best results, clamp the workpiece and use a drill press when precision is required. Use cutting lubricant when drilling metals and avoid excessive feed force to prevent overheating. Replace the bit when signs of wear or chipping appear to maintain hole quality and safety.
