I know this is probably nothing like what you're looking for, but we use these at work. We have 45 degree and 82 degree (for bolts). They work amazingly and will make a hell of a bevel with almost no spindle loads. The only thing that sucks is the Tungaloy inserts are about 80 bucks each...good thing is, they're tough and they usually last a long time. You can also flip them over.
