The head unscrews and swaps for 45°, 360°, low-profile 90° or heavy-duty 90° heads on the same motor, per the listing. The 21 CFM figure is the one to check against your compressor.

It takes the same 1/4"-28 thread as the countersink cutters and the Wescon microstop listed here. Hole sizes: drill chart.
