Step Drill Hss 6-39mm M2 Carded

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.

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.

Safety

• Wear eye, ear and cut-resistant gloves when drilling sheet metal.
• Clamp work securely; reduce RPM at larger diameters to limit heat and grab.
• Use cutting fluid on metals; clear chips frequently to avoid built-up edge.
