Questions about this item
What does the 37/64 inch size mean when I fit this bit in a drill?
The 37/64 inch diameter creates a 0.5781 inch hole, and the 1/2 inch reduced shank fits standard three-jaw chucks without needing a larger chuck.
How does the 3-flat shank affect grip in a keyed or keyless chuck?
The three flats give the chuck jaws positive contact surfaces, reducing slip under heavy torque compared with a round shank.
