Q: What is the countersink angle for flush phillips screws like part number NAS333CPA6? and do you sell the proper countersink that would fit in a normal drill chuck?

The NAS333 machine screws have a 100* countersink. The countersink tools we offer have 1/4-28 threads and commonly used with a microstop cage. You can purchase a drill extension like part # 12-01535, which has female 1/4-28 threads, and be able to use a normal drill chuck with these countersinks. You can view these parts on our web site if you search "countersink cutter" and "drill extension".
