Since 1857, the company operated by Mathias Klein and his descendants to the fifth generation, has grown and developed along with the telecommunications and electrical industries where Klein pliers first found major usages. Today, Klein Tools, Inc. represents much more than Klein pliers. The company's product line has broadened to include virtually every major type of hand tool used in construction, electronics, mining, and general industry in addition to the electrical and telecommunications fields. Klein offers a lifetime warranty on material defects and workmanship for the normal life of the product. The Klein 59014 High Speed Steel Step-Drill Bit allows you to drill multiple-size holes in thin sections of metal, plastic, and wood using a single bit. The fractional unibit works in most metals (steel, brass, aluminum, copper), as well as in plastic and wood. The anti-skid tip eliminates the need for center punching or pilot hole drilling for most sizes. The single-fluted design prevents skidding and makes for easier re-sharpening. This unibit has 1/8-inch penetration with each step and diameter ranges from 3/16- to 7/8-inch holes. The 59014 also features laser-etched hole sizes that are easy-to-read and permanent. The Klein 59014 High Speed Steel Step-Drill is sold one item per package.
