Description
The 3.5mm HSS long series drill bit delivers extended reach for deep drilling, templates and access beyond fixtures in mild steel, aluminium, brass, timber and plastics. Precision-ground geometry aids accurate starts and steady tracking, while lengthened flutes improve chip evacuation. Compatible with standard chucks on cordless and corded drills or drill presses. Ideal for cabinetry, jigs, electrical work and light fabrication. In metals, run at reduced speeds, apply cutting fluid and peck frequently to clear chips, minimising heat and deflection for precise hole quality.
