All-in-One Solution for Multi-Size Hole Drilling

The Metro 3 Pcs HSS Step Drill Bit Set is a versatile drilling solution designed for creating multiple hole sizes using a single bit. Made from high-speed steel (HSS) and often titanium coated, these step drill bits offer excellent durability, smooth cutting, and long life.

This set includes three cone drill bits with multiple step sizes, allowing you to drill precise holes in metal sheets, wood, plastic, brass, and aluminum without changing bits.

🔧 Key Features:

✔️ 3-Piece Multi-Size Set – Covers wide drilling range (4–12mm, 4–20mm, 4–32mm)
✔️ HSS Steel Construction – Strong, heat-resistant & durable
✔️ Titanium Coating – Reduces friction & increases lifespan
✔️ Step Cone Design – Drill multiple sizes with one bit
