Step Drill bits 3 pcs

From 4 mm up to 32 mm. A step drill bit is a conical drill bit with multiple stepped cutting edges of increasing diameter. It’s mainly used for drilling clean, precise holes in thin materials like sheet metal, plastic, and soft wood. Each step on the bit corresponds to a different hole size, eliminating the need for multiple bits. Common Uses: Drilling holes in electrical panels and junction boxes Enlarging existing holes Working with thin metals and plastics Chamfering edges Advantages:. ✔ Versatile: One bit covers multiple hole sizes ✔ Clean Cuts: Reduces burrs and deformations ✔ Durable: Coated versions (e.g., titanium nitride) extend lifespan ✔ Efficient: No need to switch between multiple drill bits How to Use a Step Drill Bit: Mark the hole location using a center punch. Start drilling at low speed with steady pressure. Increase speed as the bit progresses through the material. Lubricate (if needed) when drilling metal to reduce heat and wear. Deburr (if necessary) with the same drill bit or a deburring tool. It's a very handy tool to have around the house or at the work place.
