## Summary description

Step drill bit Irwin 10502853 designed for drilling progressively larger holes with a single tool. This step bit has a drill diameter of 2.2 cm and is intended for use with a drill. It is suitable for creating and enlarging holes in thin materials and for tasks where multiple hole sizes are required without tool changes.

## Long description

The Irwin 10502853 step drill bit is engineered to drill progressively larger round holes with a single cutting tool. With a maximum step diameter of 2.2 cm, this step bit is intended for use with standard power drills to create and enlarge openings in thin materials such as sheet metal. Constructed from industrial-grade M7 high speed steel and featuring a self-centring point and a flatted shank, it delivers controlled drilling performance and reduces the need for centre punching or frequent tool changes.
Advantages
The single-flute design provides improved control when drilling into sheet metal and helps produce clean, circular holes. The flute geometry is optimized to evacuate chips and reduce burring, while the self-centring point prevents walking at the start of a cut for accurate hole placement. The M7 high speed steel construction offers hardness and wear resistance suitable for repeated use in thin metallic materials, and the flatted shank minimises slippage in the drill chuck.
Suitable for
 Drilling and enlarging holes in sheet metal
 Electrical and HVAC installations where multiple hole sizes are required
 Metalworking tasks on thin steel, aluminium or similar gauge materials
 Situations that require quick step-size changes without swapping tools
Key specifications
 Tool type: Step drill bit
 Maximum drill diameter: 22 mm
 Material suitability: Sheet metal and thin-gauge metals
 Cutting material: M7 high speed steel
 Flute design: Single flute for chip evacuation and control
 Tip type: Self-centring point to prevent walking
 Shank style: Flatted cylindrical shank to reduce chuck slip
How to use
Mark the hole centre and clamp the workpiece securely to prevent movement. Fit the step drill bit into the drill chuck and tighten the flatted shank to reduce slippage. Start drilling at low speed to allow the self-centring point to locate the hole, then increase speed as appropriate for the material thickness. Apply steady, moderate pressure and withdraw occasionally to clear chips. For larger final diameters, progress through the steps without changing tools, stopping briefly between steps to ensure a clean cut.
Usage recommendations
Use cutting fluid or light oil when drilling stainless or thicker sheet metals to extend tool life and improve chip evacuation. For the best results, secure thin panels with clamps and support the area around the hole to reduce vibration and deformation.
