        Great for drilling high tensile steel!

        Comments about Bosch 18-Piece Cobalt Drill Bit Set:

        I bought this set because I had to shorten the wheelbase of a tandem axle feed truck by four feet and opted to just redrill all of the holes instead of cutting the frame. These bits drilled through the frame steel like it was wood. Granted a slow drill and cutting oil helped but these bits deserve all of the credit!! They made a tough job very easy!

          "Made in China"

          Comments about Bosch 18-Piece Cobalt Drill Bit Set:

          The bits are manufactured in china and quality suffers because of this. But don't worry, the case is made in the USA. The larger bits on the set I purchased are fairly good with definitive points to prevent walking. The smaller bits do not have a definitive point, but rather a spade or flat tip from not being cut properly. This causes the smaller bits to walk substantially, even when using a punch.
