YG1 Step Drill HSS 4-32mm UAE

YG1 Step Drill 4-32mm — One Tool, Many Holes

Single-piece HSS step drill that produces clean, deburred holes from 4 mm up to 32 mm in sheet metal, plastic, plywood and thin-wall tube — without changing tools. Each step is laser-marked with its diameter for fast on-the-job sizing.

Specifications

• Diameter range: 4–32 mm in 2 mm steps (15 steps)
• Material: Premium high-speed steel (HSS) with TiN coating
• Shank: 10 mm parallel (3-flat anti-slip) for hand drills and chucks
• Coolant requirement: Light cutting oil for ferrous, dry for non-ferrous

Best for

Sheet steel up to 4 mm thick, aluminium, copper, brass, stainless sheet, plastic, fiberglass, plywood. Not for solid stock above ~4 mm depth — switch to a jobber drill in that range.

Why a step drill

Eliminates the need for a separate pilot drill, deburring tool, and chamfer mill. The conical geometry self-deburrs the entry hole and leaves a 90° chamfer ready for countersunk fasteners — a single hole-making operation in one pass.
