SELF CENTRING TIPPED HSS-CO 5% STEP DRILL BIT SET 1-10 MM

Special drill bit set for clean, round holes even in thin-walled materials. The self-centring step tip removes the need for centre punching, allowing controlled drilling without wandering. It’s especially effective on broken studs, pipes, curved panels and other surfaces where standard drill bits struggle to start cleanly.
