Contaminating stainless with countersink


We are punching and then countersinking for a No.8 or No. 10 screw stainless 304 & 316L half oval stripping. We are concerned about contaminating the parts with our current method of high speed steel single flute countersinks. We cannot find stainless countersinks. What metal can we use as an option or can we get stainless countersinks? We process over 160,000 ft of stripping a month and countersink every 6 inches of each part. Currently we resharpen the countersinks.

Why not use carbide or cobalt?
