Heavy-Duty 5-Piece 12-Inch HSS M2 Steel Drill Bit Set, Black/gold finish. Tri-flat shank except 1/8-inch (round). Aluminum carry case included. The bit is manufactured with long lasting HSS M2 steel, heat-treated, and made to last. HSS M2 steel is one of the strongest material available for drill bits, surpassing coated titanium, carbide, or cobalt drill bits. This drill bit is perfect for all purpose uses, drilling thru soft and hard materials. Extra length allows for deeper drilling and for harder to reach locations.
