BOSCH 2608587427 step drill bit HSS 10-4, 10 x 125.5 mm

With this Bosch hss step drill bit, you drill and enlarge clean holes from M10 to M40 in thin sheet steel, non-ferrous metals, and plastic without switching accessories. The integrated split-point tip delivers immediate, accurate spot-drilling without prior center punching. As you step up to larger diameters, hole edges are deburred automatically while preventing thin sheet deformation. Thanks to the 10 mm 3-flat shank, this 125.5 mm drill bit remains securely clamped in your chuck without slipping. This lets you install cable glands and conduit fittings in electrical cabinets quickly and with full control.
