\n\tSpecifications:\n\n\tWhen encountering the thick steel bar in the wall, there will be no embarrassment of sticking or damaging the alloy. It can easily pass through thin steel bars within 6mm (1/4 inch).\n\n\tThe alloy electric hammer drill bit is made of 40Cr steel and YG8C cemented carbide, which is durable and strong. Based on the materials, after high temperature quenching, the hardness is greatly improved. The surface treatment of the processing makes this product better in appearance and use than generally medium carbon steel drills,\n\n\tIt is compatible with all SDS-plus size electric hammer bits such as for Bosch, for DeWalt, for Hitachi, for Hilti, for Makita, for Milwaukee, etc.\n\n\t \n\n\tItem Name: Drill Bits\n\n\tMaterial: Alloy Steel, Tungsten Carbide Alloy\n\n\tQuantity: 9Pcs\n\n\tDrill Bits Specifications: Metric: 1 x 5mm, 2 x 6mm, 2 x 8mm, 1 x 10mm, 1 x 12mm, 1 x 14mm, 1 x 16mm, Imperial: 1 x 3/16\", 2 x 1/4\", 2 x 5/16\", 1 x  3/8\", 1 x 1/2\", 1 x 9/16\", 1 x 5/8\"\n\n\tFeatures: Durable, Hardware Tools, Anti-rust, Strong\n\n\tLength: 16cm; 6-1/4 inch(Approx.)\n\n\t \n\n\tNotes:\n\n\tDue to the light and screen setting difference, the item's color may be slightly different from the pictures.\n\n\tPlease allow slight dimension difference due to different manual measurement.\n\n\t \n\n\tPackage Includes:\n\n\t9 x Drill Bits
