HSS Titanium Coated Step Drill Bit – 4-20mm & 4-32mm Cone Hole Cutter

Cut clean, precise holes through metal, wood, plastic, and more with this HSS Titanium Coated Step Drill Bit. Available in two popular size ranges — 4-20mm and 4-32mm — these cone-shaped step drills let you drill multiple hole sizes with a single bit, saving time and tool changes on every job.

Whether you're a weekend DIYer or a seasoned tradesperson, this step drill bit delivers professional-grade results with every use. The titanium coating dramatically increases surface hardness and reduces friction, so the bit stays sharper for longer and cuts faster with less effort.

  • Two Size Options – Choose 4-20mm or 4-32mm to suit your specific project needs
  • Self-Centering Tip – Starts drilling cleanly without a pilot hole or center punch on most materials
  • Versatile Use – Ideal for metalworking, woodworking, electrical panels, sheet metal, PVC, and more
  • Compatible with Standard Drills – Fits most corded and cordless drills and drill presses

Frequently Asked Questions

Q: What materials can the HSS Titanium Step Drill Bit cut through?

A: This HSS titanium coated step drill bit is designed to cut through a wide range of materials including mild steel, aluminium, sheet metal, wood, MDF, plastic, and PVC. It is not recommended for hardened steel or masonry surfaces.

Q: What is the difference between the 4-20mm and 4-32mm step drill bit sizes?

A: The 4-20mm step drill bit provides hole sizes ranging from 4mm up to 20mm, making it ideal for smaller precision holes. The 4-32mm version covers a larger range up to 32mm, which is better suited for bigger openings such as electrical conduit knock-outs or larger panel holes.

Q: Do I need a pilot hole before using this step drill bit?

A: No — the self-centering tip on this cone drill bit allows it to start cutting directly on most flat surfaces without needing a pre-drilled pilot hole or center punch, saving you time and setup steps on your project.

Q: Is this step drill bit compatible with standard cordless drills?

A: Yes. This step drill bit features a standard hex or round shank that is compatible with most corded and cordless drills as well as drill presses. Check the specific shank diameter against your drill chuck before purchasing if you have a specialised tool.
