1 o Micro Tools for Smll Bores METRIC

2 o Micro Tools for Smll Bores The Microscope line offers new nd improved solutions for micro oring, grooving, chmfering nd threding in ores s smll s 1.0 mm. The Microscope line offers lrge nd extended rnge of single-ended inserts nd full rnge of tool holders with simple clmping system. See it in ction Improved Coolnt Thru Two coolnt holes for effective chi p removl nd cool ol in g of cutting edg dge Slnted Insert Design Provides exct insert loction for high rep etility Simple Clmping System Simple nd fool- proof. The new clmping system uses one lrge screw to secure the inse sert in the holder Stopper Pin Provides precise cutting edge height nd per erfe ct xil loction 2
