Step drill bit Cimco Werkzeuge 201275 — right-hand rotation, 1 piece

The Cimco Werkzeuge step drill bit 201275 is a single-piece right-hand rotation tool designed for progressively enlarging and deburring holes in sheet metal and other thin materials. As a step drill bit, it combines multiple diameters in one cutting edge, allowing incremental drilling without frequent tool changes. The tool is intended for tasks where clean, aligned holes are required in metalworking, electrical panels and plumbing fittings.

Advantages

This step drill bit offers a compact, single-piece design that simplifies hole sizing with progressive steps. The right-hand rotation geometry provides stable cutting performance and predictable chip evacuation. A cylindrical shank ensures secure clamping in standard chucks and holders, while the coated dark finish on stainless steel surfaces enhances wear resistance during repeated use. Supplied as one piece, it is ready for immediate installation on drills and drill presses.

Suitable for

• Drilling and enlarging holes in thin sheet metal and light-gauge steel
• Creating and deburring openings for electrical panel components and conduit entries
• Preparing holes for plumbing fittings and HVAC installations
• Workshop and maintenance tasks requiring multiple hole diameters without tool changes

Key specifications

• Tool type: step drill bit
• Rotation direction: right-hand rotation
• Maximum drill diameter: 3.2 cm
• Shank type: cylindrical shank for standard chucks
• Material and finish: stainless steel with dark/black surface finish
• Quantity: 1 piece

How to use

Secure the cylindrical shank firmly in the drill chuck or appropriate holder to prevent slippage. Select a suitable drilling speed for thin metal—moderate to high speeds are common with step drills depending on material thickness—and apply steady, even pressure while allowing the tool to cut through progressively sized steps. Use cutting lubricant or light oil when working with stainless steel or thicker materials to improve tool life and surface finish. After reaching the desired diameter, retract the tool while the drill is running to clear chips and reduce burring.

Usage recommendations

For best results, start with a pilot mark to center the step drill and avoid walking. When drilling electrical panels or thin materials, support the workpiece to prevent deformation and ensure clean edges. Replace the bit if wear or rounded steps degrade hole quality.
