Centre drills are for making tapered holes, to locate on to a lathe centre..... Spotting drills are for making a starting dimple for drilling, in CNC machining. The dimple is often made wider than the drilled hole, to leave a chamfer around the finished hole....... And, there is no tiny centre pip to break off......... :bang: :bang: David D |
