O.D. and I.D. Turning/Specialty Turning • Small Hole Boring/A/B Series Small Hole Tooling Widia Small Hole Tooling A/B Series is optimized for versatile use in the high-performance micro hole making. The A/B Series range of high-precision turning from Widia promises an affordable cost of cutting for the internal diameter range from 1,56 mm to 3,96 mm. Depending on your type of material, the micro boring bar is suitable for both manual machining on drilling and turning machines and automatic CNC machine as well. These pinpoint series are also available with 3 different specs to choose from; the ABD Type which is a replaceable boring insert with coolant slot and TICN coating, the ABD-M Type with carbide uncoated, coated with CBN (Superhard cubic boron nitride/cBN) for Cast Iron / Sintered Metals, and PCD (diamond) tip for highly abrasive material, and finally the BB type which is made of regular HSS material. Your investment in Widia Small Hole Tooling A/B Series will allow you to run a very economic application from creating a small hole on a precision workpiece manufactured for aerospace, making micro bore for pin joints on heavy equipment, initial boring on making tapered holes on the hard metal of automotive blocks and many subcontracting machining jobs for defense military as well. Widia Small Hole Tooling A/B Series Features: 1,56 - 3,96 mm diameter of boring range Unique locking system enables quick setting and accurate insert changes Insert repeatability guaranteed within 0,013 mm Available in multiple styles of machining a wide range of materials Designed with elliptical, ground insert shanks that provide excellent grip, strength, and rigidity. Available in both metric and inch sizes. PDF catalog on metric can be downloaded here and on inches here (103 MB)
