Designed for drilling and enlarging round holes in thin metal sheets and similar materials, it provides progressive hole sizes without tool change. Suitable for electricians, plumbers and metalworkers for fast, controlled holemaking.

## Long description

The step drill bit c.k tools T3012 HSS 12.5–32.5 mm, length 80 mm is a high-speed steel stepped cutter designed to drill and enlarge round holes in thin metal sheets and comparable materials. Its stepped profile provides multiple progressively larger diameters in a single tool, allowing users to create or enlarge holes without changing bits. The tool is built to deliver controlled, burr-reduced cutting for applications that require a range of hole sizes within the 12.5–32.5 mm span and an overall working length suited to access in confined spaces.
Advantages
This HSS step drill bit combines a range of diameters in one cutter to reduce tool changes and simplify holemaking tasks. The stepped geometry enables progressive enlargement and more consistent hole roundness compared with using multiple twist drills. Its 80 mm overall length balances reach and rigidity, providing stable cutting in thin sheet materials. The HSS material ensures heat resistance and wear performance suitable for drilling common ferrous and non-ferrous sheet metals.
Suitable for
Drilling and enlarging holes in thin metal sheets, such as steel, aluminum, and brass
Electrical enclosures, panel work and conduit entry holes
Plumbing fittings and HVAC ducts where multiple hole sizes are required
General metalworking and maintenance tasks that need progressive hole sizes without tool changes
Key specifications
Material: high-speed steel (HSS)
Step diameter range: 12.5 mm to 32.5 mm (progressive steps)
Overall length: 80 mm
Design: stepped cutters for progressive hole enlargement
Suitable workpiece thickness: optimized for thin sheet materials
How to use
Select an appropriate drill speed for the sheet material and secure the workpiece to prevent movement. Mark the desired hole centre and start drilling with light pressure to engage the leading step, then apply steady feed to progress through the successive steps until reaching the required diameter. Use cutting fluid when working with thicker or harder materials to reduce heat and extend tool life. Retract periodically to clear chips and check hole size; deburr the hole edges after completing the cut for a clean finish.
Usage recommendations
For best results, use moderate spindle speeds and consistent axial feed when cutting thin metal sheets. Clamp the workpiece firmly, apply cutting lubricant for stainless or hard alloys, and avoid side loads to maintain concentricity and prolong tool life.
