Slash Cycle Times by Combining Drilling and Chamfering in One Step
In the competitive world of job shop manufacturing, the biggest drain on profitability isn't always the material cost -- it's the "hidden tax" of tool changes and idle spindle time. Every time a machine stops to swap a drill for a chamfer tool, the cycle time climbs and the margin thins.
Heule Precision Tools is tackling this head-on with their COMBI tooling system, a high-efficiency solution designed to combine drilling, chamfering, and deburring into a single, seamless operation.
The COMBI tool is essentially a multi-tasking powerhouse. By integrating a standard spade drill with Heule's specialized SNAP chamfer blade, shops can produce a finished hole -- deburred on both the front and back -- in one pass.
For shops handling high-volume automotive components like brake discs and axles, or massive parts for heavy equipment, the ability to eliminate two or three tool changes per hole is a game-changer for throughput.
The mechanical brilliance lies in the motion.
The tool drills through the workpiece, then transitions immediately to chamfering. The SNAP blade is designed so that only its ground sliding surface touches the bore, protecting the hole's integrity as it moves. Most importantly, there is no need to stop or reverse the spindle. Once the blade clears the back of the part, it extends to catch the rear burr on the return stroke before rapping out to the next coordinate.
Available in diameters ranging from 9.5 mm to 35 mm, these tools are built for the rigors of the shop floor. They feature through-coolant capabilities and customizable lengths to maintain maximum rigidity. By consolidating operations into one compact tool body, shops can free up tool carousel spots and slash cycle times simultaneously.
