## Long description

Step drill bit KWB 524010 with a 2.4 cm cutting diameter is a carbon-steel body reamer made for enlarging and shaping holes in thin non-ferrous metals, plastics and wood. Supplied as a single piece, the tool is suitable for precise stepwise drilling where several hole diameters are required from one pilot entry. The product is compatible with tasks such as installing car radio aerials and other applications that need progressive hole enlargement.

The stepped profile enables multiple hole sizes from a single tool, reducing tool changes. Its 2.4 cm maximum diameter allows controlled enlargement from small pilot holes to larger openings in thin materials.

How to use
Secure the workpiece and mark the pilot hole location. Fit the step drill bit into a suitable drill or driver with the correct chuck size. Start at low speed to create or align the pilot hole, then increase speed gradually while applying steady, moderate pressure to step through successive diameters until the required size is reached. Retract occasionally to remove chips and avoid overheating.
Usage recommendations
Use cutting fluid or light lubrication when working with metals to prolong tool life and improve finish. For plastics and wood, use lower speeds to prevent melting or splintering. Ensure the drill is perpendicular to the work surface for accurate, round holes and wear appropriate eye protection.
