I found square head set screws for about $1.00 each at McMaster
Too many things going on to bother listing them.

yes Greg, that is the proper way, and the original Aloris method for parting tools .
Some of the Aloris imitators made them straight to save costs

Thanks, Rich. That's interesting as I see lots of illustrations and holders other than the Aloris type that run the tool in straight, zero rake.

Re: Best cutoff tool profile?
nice thing about holders with rake....very easy to 'level the tool off' in a grinder if you want zero rake'.
this is something that I do with some materials....

Re: Best cutoff tool profile?
My best cut off blade is one made with high grade HSS German steel. All the cheap Imports and off brand (HSS) blades I’ve used are basically poor to worthless. So have become a believer that the grade of steel is more important than the profile…

Re: Best cutoff tool profile?
Just a note. Steels alloys are defined by standards, typically SAE, ISO or UNS. Regardless of where they are made if they meet this specification then they are they same everywhere. Referring to steel by country is a marketing gimmick that should be eliminated.Glenn Brooks wrote:My best cut off blade is one made with high grade HSS German steel.

An M35 HSS tool coming out of China will always have a higher hardness than an M2 tool out of Germany.
Note that I am assuming here that the manufacturer is honest and what they say the steel is is in fact what it is. Unscrupulous behaviors is another kettle of fish here and sure it can be more prevalent in some portions of the world than others.

Obviously, you have not dealt with Chinese manufacturer. I worked for a major computer company and rejecting non-compliant parts was a full job.Note that I am assuming here that the manufacturer is honest
I am not talking about the rare defective part; I am talking about cheating by a process that could not possibly meat the specs.
