The Cimco 201207 step drill bit is a single-piece cutting tool engineered for drilling stepped holes with a maximum diameter of approximately 12 mm. Designed for use on thin sheet materials and similar substrates, this step drill bit delivers concentric, graduated hole sizes in a single operation, reducing the need for multiple drill bits or reaming. The solid construction and ground cutting edges provide consistent hole quality and reduced burr formation for cleaner finishes.

Advantages

This step drill bit offers multiple diameter steps in one tool, enabling fast transitions between hole sizes without changing bits. Its single-piece design enhances rigidity and stability during drilling, which helps maintain concentricity and reduces wobble. The stepped geometry promotes efficient chip evacuation and smoother cutting action, resulting in fewer burrs and longer usable life when used within recommended parameters.

How to use

Secure the workpiece and mark the hole center before drilling. Install the step drill bit into a drill or drill press chuck, ensuring the shank is firmly clamped. Use steady, moderate speed appropriate for the material—lower speeds for harder metals and higher speeds for softer metals and plastics. Apply consistent axial pressure and allow the tool to cut through each step gradually rather than forcing the bit, which preserves edge life and produces cleaner holes. Retract occasionally to clear chips if drilling thicker sections or when cutting multiple steps.

Recommendations

For best results, use cutting fluid when drilling metals to reduce heat and improve chip evacuation. Start at a pilot mark to prevent walking, and choose drill speed and feed that match the material hardness. Inspect the bit for wear and replace when edges become dull to maintain hole quality.

Key Highlights
  • Drilling holes in thin metal sheets such as steel, aluminum, and brass
  • Creating holes in plastics, laminates and composite panels
  • Enlarging or deburring existing holes to defined stepped diameters
  • Workshop, maintenance and general DIY tasks requiring multiple hole sizes
  • Tool type: step drill bit (single piece)
  • Maximum diameter: 12 mm (approximately 1.2 cm)
  • Material compatibility: suitable for thin metals, plastics and similar substrates
  • Cutting geometry: multiple stepped diameters along the flute
  • Shank: straight shank intended for standard drill chucks
