CLARKE CHT384 COBALT DRILL BIT SET
Snapping a stud, or bolt, so that a large section remains seized in the hole, is a nightmare. But the scenario becomes worse if the snapped fastener was high tensile or hardened steel.

Clarke’s CHT384 spans 1-13mm in half millimetre increments, and all bits are made from super durable Cobalt steel.
