Bosch Hex Shank Hss Step Drill Bit

The bosch hex shank hss step drill bit is a versatile stepped drill bit designed to drill multiple hole diameters with a single bit, delivering smooth, burr-free results in thin sheet materials. The split-point tip eliminates the need for pre-punching, allowing for a clean, accurate start without the bit wandering. A cnc ground spiral flute optimises chip removal and reduces vibration, while axial and radial relief grinding ensures consistent cutting performance and a smooth finish throughout each step. This step drill bit is suitable for use on non-ferrous metals, sheet steel, stainless steel, and sheet plastic making it a practical choice for electricians, fabricators, and engineers working with thin materials. The hex shank provides a secure, positive connection in both three-jaw chucks and internal hex tool holders. Laser-marked diameter figures on both spiral flutes remain clearly visible throughout the life of the bit. Features and benefits: drills multiple diameters from 4mm to 20mm with a single bit split-point tip for easy, accurate starts without pre-punching cnc ground spiral flute for optimised chip removal and reduced vibration axial and radial relief grinding for consistent cutting performance and smooth finish hex shank for secure connection in three-jaw chucks and hex tool holders hss construction for long service life extended further with coolant use laser-marked diameter figures on both flutes for easy, durable identification specifications: total lengt...
