【Material】Our drill bits are made of high-quality high-speed steel, offering exceptional hardness and cutting edge. These helix drill bits are designed for drilling steel, cast iron, non-ferrous metals, alloys, and unalloyed materials. 【High Efficiency】The 118-degree point angle reduces centering and travel times. Short cutting edges minimize resistance, allowing for faster and effortless drilling. The precision drill bits offer excellent heat and wear resistance and are suitable for both pillar drills and bench drills. Their manufacture according to strict standards guarantees a flawless finish. 【Dimensions】1 mm / 1.5 mm / 2 mm / 2.5 mm / 3 mm / 3.5 mm / 4 mm / 4.5 mm / 5 mm / 5.5 mm / 6 mm / 6.5 mm / 7 mm / 7.5 mm / 8 mm / 8.5 mm / 9 mm / 9.5 mm / 10 mm / 10.5 mm / 11 mm / 11.5 mm / 12 mm / 12.5 mm / 13 mm. Supplied in a durable metal case for organized storage. 【High Durability】Increased drilling speed generates less heat and therefore less wear. The centering point ensures fast and easy drilling by preventing the drill bit from deviating. Suitable for drilling steel, cast iron, non-ferrous metals, and alloy and unalloyed materials. 【25-Piece Drill Bit Set】Professional, precision-ground drill bits allow for fast drilling with low pressure, enabling you to drill without pre-drilling or pilot holes.
