Combination Tools Improve Machining Center Productivity


With today's CNC technology, it is possible to combine drilling, tapping and chamfering in a single operation by using specially designed cutting tools.

A good example  is the Thriller Tool, manufactured by Thriller, Inc. (Dearborn, Michigan), a division of the Turchan Technologies Group. This tool can perform in a single operation what usually calls for a drill, chamfering tool, and tap or thread mill. In so doing, this kind of combination tool reduces the number of tools, toolholders and tool positionings required, and it eliminates tool changes between operations. Properly applied, the result is a significant cost and time savings.

Allied Machine  combination tool for drilling and chamfering.


A part made of modified 4140 steel, required a considerable amount of holemaking. It has 57 1.362 "-dia., 2½ "-deep through-holes and 54 1.438 "-dia., 4½ "-deep through-holes.

RMC was applying three cutting tools to complete each of the 57 holes: a drill, a twin boring bar and a chamfer mill. The challenge was consistently achieving the tolerance while maintaining the production rate, . “The ±0.002 " tolerance was too tight for the twin boring bar setup.

The shop then decided to have a special made to both drill the hole and cut the 0.150 "×45° chamfer. It is tooled with the GEN3SYS XT insert and the tool body was customized to have a built-in chamfer. It shortened the cycle time and  also reduced inventory by eliminating the boring bar and chamfer mill.

RMC runs two parts before replacing an insert. Each tip is reground at least once. Reground inserts provide  identical performance. By switching to this comnination GEN3SYS XT drill, RMC went from a 1,600-rpm spindle speed, 524-sfm cutting speed, 8.0-ipm feed rate and 1-minute cycle time per hole, to 865 rpm, 308 sfm, 12.11 ipm and 14.12 seconds per hole.
