The 4.3mm HSS jobber-length drill bit is engineered for clean, accurate drilling in mild steel, aluminium, brass, timber and plastics. Precision-ground geometry supports fast starts and reduces bit wandering, while optimised flutes aid chip clearance and cooling. Compatible with standard chucks on cordless drills and drill presses. Ideal for clearance holes, brackets, fixtures and maintenance tasks. In metal, use cutting fluid, select suitable speeds, and clear chips frequently to prolong tool life and maintain clean, round holes with minimal burring and distortion.
