Ingco HSS Drill Bit Metal 14mm 5pcs DBT1101403

Our review

This Ingco set gives you five high-speed steel drill bits, each 14mm in diameter, with a total length of 160mm and a usable flute length of 108mm. That makes them suited to metalwork where you need a larger hole, such as clearing bolt passages, running conduit, or fitting heavier fasteners. The five-piece pack also means you have spares when one bit dulls or snaps, which is common at this diameter if you push too hard. Before buying, confirm your drill chuck accepts a 14mm shank and that your material thickness sits within the 108mm usable length. Compare against cobalt or titanium-coated bits if you regularly drill stainless or hardened steel, since plain HSS wears faster there. Also check whether you need a pilot bit first, as 14mm is large enough to wander on smooth surfaces. The bits come packed in a poly bag, so plan your own storage to keep edges protected. Available on Sokonia.
