HSS Titanium Step Drill Bit 5–35mm | 13-Step Cone Cutter for Wood, Metal & PVC

Tackle any multi-size drilling task in one pass with this High Speed Steel (HSS) Titanium Step Drill Bit. Featuring 13 progressive steps from 5 mm to 35 mm, this spiral-grooved cone drill lets you cut clean, precise holes in wood, thin sheet metal, aluminium alloy, PVC panels, and insulation boards — no pilot hole required. The titanium coating combined with a nitrogen-treated surface dramatically reduces friction, keeps the bit running cooler, and extends tool life through job after job.

Key Features

No Pilot Hole Needed — Self-starting tip digs in immediately, saving setup time.
Titanium + Nitrogen Treatment — Dual surface treatment increases hardness, abrasion resistance, and reduces heat build-up during use.
Auto-Deburring — Spiral grooves automatically deburr holes as you drill for clean, finished edges.
13 Steps in One Bit — Sizes: 5, 7, 10, 12, 15, 17, 20, 22, 25, 27, 30, 32, and 35 mm.
Versatile Material Compatibility — Ideal for wood (up to 4 mm), thin iron plate, aluminium, PVC panels, and insulation boards.
Triangle Round Shank — Prevents slipping in chuck for maximum torque transfer and drilling accuracy.
CE Certified — Meets safety and quality standards for peace of mind.

Frequently Asked Questions

Q: What materials can the HSS titanium step drill bit cut?

A: This step drill bit is designed to cut through wood (up to 4 mm thickness), thin iron plate, aluminium alloy, PVC panels, and insulation boards. Its high-speed steel core and titanium-coated surface make it highly versatile across a wide range of common DIY and trade materials.

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

A: No — the self-starting pointed tip means you can drill directly into your material without pre-drilling a pilot hole, saving you significant time and effort on the job.

Q: How many hole sizes does this single step drill bit cover?

A: This cone step drill covers 13 different hole sizes in a single bit: 5, 7, 10, 12, 15, 17, 20, 22, 25, 27, 30, 32, and 35 mm — effectively replacing a full set of individual bits for thin-material drilling tasks.

Q: What type of drill chuck is compatible with this bit?

A: The bit features a triangle round shank (23 × 13 mm) that fits standard drill chucks. The anti-slip triangular shape ensures a secure grip, maximising torque transfer and preventing the bit from rotating in the chuck during use.
