When Sure-Fab LLC wanted to speed up the process for putting a 5.125 inches counter bore 3.25 inches deep on the end of a large cylinder ram, it called on its drill supplier, Allied Machine & Engineering Corp. Sure-Fab had heard about their Revolution Drill and their Opening Drill and wanted to see if they would work on this ram application, one of many different sizes they produce, explains Allied's Larry Stenger, field sales engineer. Success stories like this are typical of today's cutting tool advances in holemaking technology. The criteria by which holemaking solutions are judged include cylindricity, straightness, finish, and accuracy. Major cutting tool manufacturers are attacking holemaking by developing full lines of products with capabilities that range from making holes to finishing them. BIG Kaiser Precision Tooling Inc has expanded its solid-carbide Phoenix drill line from 6xD to include 3xD and 12xD sizes.
