Drill Multiple Sizes in One Pass – No Bit Swapping Required

Take your DIY projects and workshop efficiency to the next level with this 3-Piece Titanium-Plated Step Drill Bit Set. Featuring three pagoda-style stepped bits in sizes 3–12mm, 4–12mm, and 4–20mm, this set lets you drill a wide range of hole sizes with a single tool. Whether you're working with wood, sheet metal, plastic, or thin steel, these step bits deliver clean, accurate holes every time.

Why Choose These Step Drill Bits?

  • Titanium-Plated Coating: Dramatically increases surface hardness and heat resistance, extending bit life far beyond standard HSS bits.
  • Hexagonal Shank Design: The 1/4" hex shank provides a secure, slip-free grip in any standard drill or drill press chuck — no slipping mid-cut.
  • Straight Groove (Pagoda) Design: The stepped cone profile allows each bit to cut multiple hole sizes cleanly, reducing the need to change bits constantly.
  • 3-Piece Versatile Set: Covers a broad range of hole diameters from 3mm to 20mm, making this set ideal for woodworking, metal fabrication, electrical panel work, and general DIY tasks.
  • Smooth, Burr-Free Results: Each step is precision-ground to produce clean-edged holes with minimal deburring required.
  • Compatible with Most Power Drills: Fits cordless drills, corded drills, and drill presses with a standard hex chuck or adapter.

Frequently Asked Questions

Q: What materials can these titanium-plated step drill bits cut through?

A: These titanium step drill bits are designed for use on wood, plastic, aluminum, sheet metal, thin steel, and other soft-to-medium hardness materials. They are not recommended for hardened steel or masonry.

Q: Do these step drill bits fit standard cordless drills?

A: Yes! The hexagonal (hex) shank is compatible with virtually all standard cordless and corded drills, as well as drill presses equipped with a 1/4" hex chuck or a suitable adapter.

Q: How many hole sizes can I drill with this 3-piece set?

A: The three bits collectively cover sizes from 3mm up to 20mm in incremental steps, giving you a wide variety of hole diameter options without needing to switch between multiple drill bits.

Q: What is the advantage of a titanium-plated coating on drill bits?

A: Titanium plating significantly increases the surface hardness and heat resistance of the drill bit, reducing friction during drilling. This results in longer bit life, faster cutting speeds, and cleaner holes compared to uncoated HSS bits.
