## Long description

Rockforce RF-44730C is a 2-piece step drill bit set designed for precise drilling and progressive hole enlargement in thin materials such as sheet metal and plastic. Each stepped bit offers a range of diameters along its length, allowing you to create multiple hole sizes and smooth chamfers without frequent tool changes. The set is intended for workshop and maintenance use where versatility and clean hole edges are needed.
Advantages
The two stepped bits provide multiple drilling diameters in a single tool, reducing the need to switch bits and saving time. Their tapered geometry enables progressive enlargement of holes with controlled feed and reduced burr formation. The design produces clean bevels suitable for fastening and finishing operations, and the compact two-piece set is convenient to store and transport.
Suitable for
 Drilling and enlarging holes in sheet metal
 Creating holes in plastic panels and housings
 Fabrication and maintenance tasks in workshops
 Installing fasteners where stepped hole diameters or chamfers are required
Key specifications
 Quantity: 2 stepped drill bits
 Material compatibility: thin sheet metal and plastics
 Function: progressive hole sizing and chamfering in a single tool
 Application: manual and machine drilling in light-duty tasks
How to use
Select the appropriate stepped bit and secure it in a drill chuck. Mark the hole center on the workpiece and clamp or secure the material to prevent movement. Start drilling at low to moderate speed, applying steady pressure to allow the step geometry to cut progressively through the material. Retract occasionally to clear chips and avoid overheating; for plastics, reduce speed to prevent melting. Finish by backing the bit out slowly to preserve the chamfer and minimize burrs.
Usage recommendations
Use cutting fluid or a suitable lubricant when drilling metal to extend bit life and improve chip evacuation. For best results on thin materials, support the workpiece near the drilling point to avoid deformation. Inspect bits for wear before use and replace if cutting edges are dulled.
