Titanium Coated HSS Stepped Drills 3-20mm

Drill, ream, and adapt to any thickness with a single tool.

HSS (high-speed steel) step drills with titanium coating are designed to drill and ream holes in sheet metal, plastic, and wood in a single pass, without needing to change bits. The titanium coating reduces friction and extends the lifespan compared to conventional drill bits.

Key features:

• Tapered step design: each bit covers multiple diameters
• Titanium coating: increased hardness and wear resistance
• Engraved depth marks to know the exact hole diameter
• Shank compatible with standard chucks and mandrels

Technical specifications:

• Material: HSS (High Speed Steel) with titanium coating
• Diameter range: 3 to 20mm (depending on variant)
• Use: thin sheet metal, plastic, and wood

Ideal for: electricians, plumbers, installers, and general DIY where various hole diameters are needed without changing tools.
