Rather than to add to the post about reduced shank bits. There was some mention of the poor performance of low priced reduced shank bits. This is partially due to the higher speeds of the more common drill presses. Most low priced drill presses run about right for the largest size bit that matches size of the shank to the lowest speed of the. drill press. I have a set of imported (China) bits to 1" with reduced shank. My common drill press (also possibly china)with a maximum 5/8 chuck runs faster than the proper speed for a 1"it. therefore I have to use caution with the larger bits. I am pleased with my Chinese bits but they will not take the abuse of excessive speed the genuine Morse or Greenfield bits may take. I do not know if the higher quality bits are made in reduced shank sizes, but I assume if the user can justify the cost of high quality bits. he may also have a better drill press with more speed selections and a Morse taper socket
