Punching a center mark improves accuracy when drilling. Accurately made with tip diameters from 1/16" to 1/4" (measured at the tip shoulder), these punches are steel with hardened tips and tempered shanks for durability.
The square shanks are knurled for grip and won't roll when placed on a work surface. Sizes stated are tip diameter by length. Sold individually or as a full set of seven in a plastic storage case.
A set of five Starrett round-shank punches is also available.
Made in USA.
