William T. Hutchinson Co. High Speed Steel Drill and Reamer Blanks have set the industry standard for quality for over 75 years. Always heat treated in a salt bath, and always triple-tempered, our blanks demonstrate superior performance when compared to those heat treated with other, less expensive methods. Regardless of diameter, our standard tolerance of two ten-thousandths of an inch (.0002") meets or exceeds the requirements for most applications.
Our M2 and M42 HSS Drill Blanks are stocked in the standard jobber drill lengths, with a +.0-.0002 diameter tolerance, in fractional, wire size, letter size and metric dimensions. Our Reamer Blanks are stocked in the same materials and sizes with a +.0002-.0 diameter tolerance. We can provide rapid turnaround on small lot specials for diameters ranging from .005" through 1.500" in lengths up to 36".
