Tork Craft Step Drill — HSS M2, 6–39 mm
Packaging: Carded (for display)
Use one drill for many hole sizes. This Tork Craft HSS M2 step drill covers 6 mm through 39 mm in progressive steps, producing round, burr-reduced holes in sheet materials. Ideal for knockout holes, enlarging existing openings, and tidy finish work in electrical boxes, panels and fittings. The precision ground cone geometry and HSS M2 substrate deliver smooth cutting and long service life.
Features
- 6–39 mm range — multiple diameters on one tool for fast size changes.
- HSS M2 — high-speed steel for durability and heat resistance.
- Progressive step profile for controlled cutting and minimal grab.
- Chamfering/countersink capability at step transitions for cleaner edges.
- Laser-marked size rings (where applicable) for easy diameter identification.
Benefits
- Fewer tool changes: Drill and enlarge holes to size with one bit.
- Smoother finishes: Step geometry helps reduce burrs and edge tearing.
- Versatile: Suitable for sheet steel, aluminium, copper, plastics and laminates (observe material thickness limits).
- Cost-effective: Durable HSS M2 construction supports long service life.
Extra Information
- Best for sheet materials; typical effective thickness up to ~4–6 mm depending on hardness.
- Use cutting fluid on metals to reduce heat and extend tool life.
- Start at lower RPM; increase gradually once the step is engaged.
Pro Tip
- To enlarge an existing hole, run the drill in reverse for a second to score the next step’s edge, then proceed forward — this helps prevent snatch and chipping on thin sheet.
