Review on Irwin 2-Inch 29-Hole Steel Drill Bit - 12092 by Troy Simpson

Just received an Irwin calibration machine and have been using it for a day going through a bunch of bits. I really like the design and functionality. The design is delicate as the holes for each drill bit size are slightly larger than the actual drill bit size. The bit will not fit in a smaller hole but will easily fit the right size. If the holes were made by simply drilling through the panel with a true size drill bit, the holes may be too narrow. The plate arrived bent due to rough handling somewhere in the shipping process. A little gentle pressure basically straightened it out. As others have noted, the page is easy to read with the dimensions painted white. I hope the white color stays.
