Combination taps can reduce costs by doing multiple operations in one pass. Jarvis offers combination tap drills, with self-centering points, and we have them ready/off the shelf. Tap and reamer combinations can also be manufactured. Piloted taps ground to close tolerances are built to meet your requirements.
Key things to remember:
1. Two operations on each tool
2. Ground with close tolerances
3. Made to reduce productions costs
