This set incorporates an automatic centre punch together with a 8mm HSS drill bit, which features a spring-loaded guide pin, and is designed to drill out or cut through spot-welds allowing for the weld to be broken and the welded panels taken apart. The centre punch is used to make an indent at the centre of the spot-weld, before offering up the drill bit to the weld. The guide pin then sits in the indent and keeps the drill bit steady and centralised as it drills through the spot-weld.
