The Cimco 207373 step drill bit is designed for drilling steel and other ferrous metals. Manufactured as a single-piece stepped design, the bit enables drilling multiple hole diameters with one tool, reducing tool changes and setup time. The construction prioritizes wear resistance and stable cutting geometry to maintain precision across steps, making it suitable for workshop and on-site metalworking tasks.

Advantages

The step geometry provides incremental hole sizes without changing tools, improving workflow efficiency when working with sheet steel and thin plate. A single-piece construction reduces vibration and risk of step separation, while durable material and heat-treated surfaces extend service life. The pilot tip simplifies centring and reduces walking on flat metal surfaces, delivering consistent hole quality across the stepped diameters.

How to use

Secure the workpiece and mark the desired drilling position. Fit the step drill bit into a drill or drill press chuck and tighten securely. Start drilling at low to moderate speed to allow the pilot tip to centre, then increase speed as appropriate for the material thickness. Apply steady, even pressure and clear chips periodically to avoid overheating. For larger diameters, progress through the steps smoothly rather than forcing the cut.

Recommendations

Use suitable cutting fluid when drilling thicker or harder steel to extend tool life and improve surface finish. When working with thin sheets, support the material to prevent deformation. Inspect the cutting edges regularly and replace the bit if wear compromises hole quality.

Key Highlights
  • Drilling holes in steel sheet and thin steel plate
  • Creating multiple hole sizes without bit changes
  • Metalworking tasks in workshops and light fabrication
  • Maintenance and repair work where versatile hole sizes are needed
  • Material compatibility: steel and other ferrous metals
  • Single-piece stepped design for multiple diameters
  • Pilot tip for improved centring and reduced walking
  • Heat-treated surface for increased wear resistance
  • Shank type: compatible with standard drill chucks
