I have been using a Dremel tool with diamond cutting disks to make custom cutting bits. They look fairly good, but it's hard to get flat even cutting edges with this hand method. Does Freight Harbor have anything that might help me make a jig to control the cuts more evenly? Do they have a diamond cutting tool that is not too expensive that will work for me?
You are shaping HSS lathe toolbits by faceting them using a diamond cutoff disk on a Dremel tool?
Have you considered hitting a couple of yard sales and looking for a bench grinder?
I suggest that you consider in a slightly larger sense what your problem is. For example, if you say "how can I use a diamond cutoff wheel more effectively" maybe there isn't a good answer. But if you say "I'm trying to turn some 316 stainless on my lathe and it's work-hardening, so I'm trying a different tool geometry on my 3/8" HSS tool bits. I'm having trouble generating the tool bit geometry I'm shooting for" then maybe someone would tell you how to turn your stainless more easily.
Perhaps I'm wrong about what you're doing. I tend to interpret things very literally. It's a common shortcoming in anyone who has ever written software.
the diamond cut off disc that harbor freight sells list for about $9.95..if i remember right it was three or four disc with a mandrel and it seemed to be able to fit the dremel tool... i was in harbor freight about 2 weeks ago buying something non related and saw the 4 by 4 card sheet with the disc and the madrel on it... noticed the price of $9.95.. not looking for them at the time i just picked it off the counter and put it back.. when i got home i was looking at their catalog sheet and found that they were on sale for $1.95.... i wish i knew that at the time as i would have gotten some and tried them out...... no special need, but for 2 bucks how much could i loose???
