Frequently Asked Questions
What is a MICRO 100 reverse boring bar used for?
A MICRO 100 reverse boring bar is used for internal machining operations where the cutting tool approaches the workpiece from the opposite direction, enabling back-facing, chamfering, and contouring in tight bores. It is common in precision toolmaking, mold work, and aerospace component manufacturing.
What are the specifications of the MICRO 100 QRB-156500 boring bar?
The MICRO 100 QRB-156500 is a right-hand, bright (uncoated) reverse boring bar with a 3/16 in shank diameter. It is designed for small-diameter internal machining where clearance is limited. The bright finish suits non-ferrous materials and light cuts where chip evacuation is critical.
