Ingco HSS Drill Bit 13mm 5-Piece Set (DBT1101303)

Our review

This is a five-piece pack of 13mm high-speed steel drill bits from Ingco, listed under model DBT1101303. Each bit measures 151mm overall with 101mm of usable flute length, and the set arrives in a poly bag rather than a case. The 13mm diameter suits drilling larger holes in metal, and HSS is the standard material for bits used on steel, though it performs best at controlled speeds with some lubrication. These are a reasonable pick for a workshop or tradesperson who already knows they need this size and wants spares on hand, since buying five identical bits only makes sense if you expect to wear them out or work on repeated jobs. Before ordering, confirm your drill chuck accepts a 13mm shank, and check whether you need a pilot bit first, as large diameters bite harder. Compare against cobalt or titanium-coated bits if you drill hard metals often, and against single-bit listings if you only need one.
