Description
A premium engineer-quality set of left-hand spiral drill bits made from M35 high-speed steel with 5% cobalt for extended tool life and superior performance on tough materials.
These precision-ground bits feature a 135° split point for accurate centring and reduced wandering, making them ideal for drilling stainless steel, high-tensile steel, and other hard alloys.
Perfect for both general engineering work and for removing broken or seized studs and fasteners. Simply drill in reverse at low speed to grip and release the damaged part.
Supplied in a durable metal storage case for protection and easy organisation.
