Micro Bore Units, Cartridges, Fine Boring Units, Bars Manufacturer

We are Manufacturer, Supplier of Micro Bore Units (MBU) / Micro Bore Cartridges / Fine Boring Units / Micro Boring Bars / Finish Bore Units and our setup is situated in Aurangabad (Chhatrapati Sambhaji Nagar), Maharashtra, India.

A cutting tool system must have a broad range of sizes and tool shapes to choose from so that the correct tool can be selected for a specific application. We offers more units in more sizes in more Angles than any other manufacturer of adjustable cutting tools. It gives maximum rigidity to the cutting edge of the tool that is necessary to obtain high accuracy, high stock removal and longer tool life. This is a used for component machining close tolerance, bearing sizes tolerance. Precision finish boring unit is high accuracy with least count of 1 micron. All Most standard units are available in the both right and left hand cutting. For standard units, prefix the order code with LH / RH. We are designed and manufactured to suitable as per customer application or requirements.

Least count +/- 0.001 mm radially.

Repeatability +/- 0.002 mm.
