Solid-carbide long drills
Iscar designed drills for small-diameter, deep holes in automotive crankshafts, camshafts, connecting rods and more—all with minimum quantity lubrication.
In the video, Iscar uses a 5.4mm solid-carbide long drill to add oil way holes to a crankshaft. The drill, designed for small diameter deep hole production, is shown drilling holes 83.2mm in depth at a speed of 81mm/min. and a feed rate of 0.18mm/rev. The turnmill machining center is run using minimum quantity lubrication.
