Feb 9, 2019. #1. Anyone make any homemade Indexable End Mill cutters? I'm looking at this one on Amazon for $40. This one seems pretty nice at a fair price. It's 1-1/2" with a 3/4" straight shank. I need either a straight shank like this or an MT3 taper. I would also like to have a set of these in maybe 2", 3", 4" and 5".

According to one source, the C variant has ground-in "wiping flats" and is considerably more expensive, compared to the TPG with just one radius ground at each corner.
1= with a 1/2 HP mill, It is best to use a smaller size indexable face mill. 2= the size of the indexable face mill should not be bigger than 1.5" you may get away with a 2". 3= the best type of inserts for a small mill (which does not have a very ridgid mill head) is, TPG32. 4= the indexable face mill head should have at least 2 inserts but 3 ...
I would like to know if any of you can give advice on smaller indexable end mills 1/2 inch upto inch .Ive been looking at a few and wondering how they perform against the regular 4 flute end mills im using now i only use chinese brand standard end mills at the momment but maybe interested in a few smaller indexable end mills if they are any ...
My indexable end mills consist of a set of Denitools (the straight, 16mm end mill measures 16.0mm across the inserts and 15mm on the body) and a Shars 3/4” 60 degree dovetail cutter that measures 0.750” across the inserts.
Things get confusing quickly with the setting angles (45, 75, 90) and insert types (SEHT, SPG, APKT, TPG (wiper). Milling machine tooling in general is overwhelming so I mostly take the approach of shopping for the project at hand, which in this case is plane vanilla surfacing with no shoulders, chamfers etc.
I am working with a Rusnok Mill with the largest capacity collet of 9/16”. I am trying to find an indexable endmill in the size of 1”1/4” x 9/16” with a straight shank. I prefer a tool with only two indexes/cutters.
Not worried about production or anything else, I'm mainly just wanting to try out an indexable end mill. But, I don't want an end mill that will break (the cutter body itself, not the inserts) taking say .100 off mild steel. Especially with a 5/8 cutter... anyway, what do you guys at HM think of Shars indexable end mills? Thanks.
I will usually be face milling carbon steel/alloy steel/SS with 48k-90k psi tensile strength. 1” cutting diameter would be the minimum, & 2” would be wide enough for my purposes. I guess I could go up to 2 1/2” cutting diameter. I have been using 3/4” diameter, 4-flute el cheapo end mills for this, & it takes too long.
Aug 11, 2015. #2. A indexable face cutter is what you thought. It uses carbide inserts that are indexed as the wear. Face cutters are wide cutters made out of tool steel. When they wear down you must have them resharpen. Fly cutters use a single tool bit. When I was working in the shops some places outlawed them as a safety hazard.
