Product Overview

The Nikken MT3T-JBD1 is a precision dial-adjustable jig boring head designed for fine boring and finishing operations. Fitted with an integrated Peacock dial indicator, the head allows micro-adjustments with graduations of 0.01 mm on diameter and a vernier sub-scale reading down to 0.005 mm. Its adjustment range of 3 mm to approximately 28 mm makes it ideal for high-accuracy hole sizing in toolrooms, jig boring machines, and precision machining environments.

The MT3 taper shank allows secure and rigid mounting, while the 10 mm tool bore accommodates standard boring bars. The included set of boring bars covers a range of applications, from fine finishing to larger roughing passes.
