Value Collection 152-2-100-.1875 Adjustable Stop Countersink

Product Description

The VALUE COLLECTION 152-2-100-.1875 is a 2-flute adjustable-stop countersink designed for precision countersinking in metalworking and fabrication applications. Built from high-speed steel with a bright polished finish, it delivers consistent, clean entry angles without chatter. The adjustable stop collar allows the operator to set a repeatable countersink depth, reducing rework on high-volume or close-tolerance jobs. The integral pilot keeps the tool centered in the existing hole for accurate seating. Overall length is 2.5 inches with a 0.5-inch head diameter and a 100-degree included angle, making it suited for flat or flush fastener seating.

This countersink fits production and job-shop environments where repeated, controlled countersink depth is required. The 3/16-inch pilot diameter and 1/4-28 straight threaded shank make it compatible with standard adjustable-stop countersink holders. With a 1.75-inch shank length and 3/16-inch shank diameter, it seats securely in compatible toolholders. Machinists, tool-and-die technicians, and sheet metal fabricators working on ferrous and non-ferrous materials will find this tool appropriate for standard countersinking operations.

Installation Notes

Installation and use should be performed by a qualified machinist or fabrication technician.
