Rotary/Wobble Broaching Custom 455 Stainless (45 Hrc Hardness)

Last week we received a phone call from a company on the east coast. They were trying to wobble broach a 1/4’’ Hex .375 deep in Custom 455 Stainless . This material is 45 Hrc, and they were having no luck, getting only 0-1 pcs per broach, using broaches from 2 very well known broach manufacturers. They contacted us after being told by these companies this Custom 455 screw could not be wobble broached. The material was just too hard.

Not only did this customer need to broach these screws, but they needed this job finished in a few days and their machine was not running because of the broaching process failing. We informed them they could wobble broach in this hard material, as we currently have other customers successfully wobble broaching in Custom 455. We sent them off 2 Rayco 1/4’’ broaches that same day. Their feedback came a day later with their relief, as the Rayco Broaches worked great, and they finished their order on time,

Here at Rayco, we hear stories like this quite frequently. It always feels good helping customers wobble broach in a material previously thought not possible. Another earned happy customer!

The proprietary Rayco Heat Treat Process truly is a difference maker when applied to HSS. There is NO Equivalent!
