Accupro 12641803254 Offset Boring Head Set 2 Inch Body

Product Description

The ACCUPRO 12641803254 is a manual offset boring and facing head set designed for precision boring operations on milling machines and machining centers. Built around the BHC2 series head with a 2 inch body diameter, this set accepts boring bars through a 1/2 inch boring bar hole and mounts via a 7/8-20 threaded shank with a 3/4 inch straight shank diameter. The manual actuation allows machinists to dial in fine offset adjustments for tight-tolerance bores. The complete 9-piece kit includes tooling needed to get started without sourcing additional accessories. Total package weight is 5 pounds.

This offset boring head set is suited for job shop, toolroom, and production environments where manual boring operations are performed on vertical mills or horizontal machining centers. It is appropriate for both roughing and finishing bore passes when used with the included 1/2 inch boring bar and 1/4 x 1/4 inch square tool bit. The threaded mount interface is standard for this class of boring head, making it a practical fit for a range of spindle adapters.
