Ultra Touch Step Drill 4-20mm | High-Speed Steel (HSS) Bit, Different hole Sizes with Single Tool

The Ultra Touch Step Drill (4–20mm) is a specialized high-speed steel (HSS) bit designed to drill different hole sizes with a single tool. Its conical shape and stepped increments allow for precise, clean drilling in thin materials like sheet metal, plastic, and wood without the need for multiple bits.

FEATURES:

• Material and Coating: Constructed from premium High-Speed Steel (HSS) with a Titanium Nitride coating. This combination increases surface hardness, reduces friction and heat, and can extend the tool's lifespan up to 4–5 times compared to standard bits.

• Step Sizes: The bit features 9 distinct steps: 4mm, 6mm, 8mm, 10mm, 12mm, 14mm, 16mm, 18mm, and 20mm.

• Shank Design: Typically equipped with a triangle or hex shank to prevent slipping in the drill chuck during high-torque operations.

• Self-Deburring: The leading edge of the next step automatically deburrs the hole created by the previous step, resulting in clean, smooth edges
