* 1/2" Reduced Shank Drills are used for drilling holes larger than the capacity of a 1/2" drill
chuck. Reduced shank drills should only be used for light to medium duty drilling applications
as they do not have the torque strength of a straight shank drill. Reduced shank is not as
hard as the body of drill to allow more flex and less breakage.
* For machine drilling in stainless steels, titanium, and other work hardening metals. The
split point is self centering and breaks up chips. Sizes over 1" are 118° split point. Flats
are ground on three sides of drill shank for positive holding in 3 Jaw Chucks.
