HSS Tapered Hex Shank Step Drill

Achieving clean and precise holes in varying diameters is simple with the HSS Tapered Hex Shank Step Drill, a versatile metalworking tool that eliminates the need for multiple individual bits. Boring through tough surfaces like stainless steel, aluminum, or copper requires a bit that maintains its edge under high friction. This HSS Tapered Hex Shank Step Drill is engineered from high-speed steel to ensure longevity and heat resistance during heavy-duty tasks. It is an ideal addition to any tool collection where space is limited but performance is essential, allowing you to transition between different hole sizes without stopping to change equipment. Key Features Multi-step design → Allows for drilling 15 different hole sizes ranging from 4mm up to 32mm with a single bit for maximum efficiency. High-speed steel (HSS) build → Provides superior hardness and thermal resistance to prevent dulling when working on dense metal sheets or steel plates. Hexagonal shank base → Ensures a secure, non-slip fit in standard drill chucks and quick-change adapters to prevent spinning under high torque. Tapered flute geometry → Clears metal shavings and debris quickly to reduce friction and provide a smoother cutting action through thin materials. Laser-etched size markings → Offers clear visibility of the current diameter so you can reach the exact hole size needed without constant measuring. Self-starting split point → Penetrates metal surfaces instantly without the need for a center punch, reducing the risk of the bit walking across the workpiece.
