End mill holders

[Batmanacw]

I bought some Shars endmill holders recently and no one will be surprised I was not impressed with them. They are useable but I'd like better. Both the 3/8 and 1/2 have around 0.0015 or tir on an endmill or dowel pin.

I just got a reasonable deal on a 1/2" Lyndex Nikken endmill holder that states an AT3 or better taper with 0.0002" tir. ($51.44 shipped)

How are the modern Lyndex EM holders? How about Sowa brand (Taiwan)?

Tne Ridiculous Machine Tools brand promises extreme accuracy from China but I am getting allergic to wasting money on mediocre.

My goal is to pre-stage several endmills I use a lot. Kind of like the cnc guys do.

Not at all surprised about your disappointment with the Shars holders. I have not bought R8 end mill holders, but I have been really impressed with the TIR on the Sowa facemill arbors I have purchased through Carbide Depot. You might also consider Bison brand, or TMX brand.

Hemley tool is a distributor for Bison. I bought a lot of tooling through their sister company Hemley Hardware. I'll probably have to call them. The only other Bison endmill holder I found online was $98 each. Quality is expensive.

I might give the Sowa 3/8" a try first at $46 shipped from Suncoast tools.

Do you have any history with Lyndex?

My only experience with Lyndex is with conventional R8 collets. I bought several sizes of Lyndex, same with Crawford, and the following set from MSC. Of the three, the Lyndex had the worst TIR.

I'll definitely report here about the one Lyndex endmill holder once I get it, good or bad.

The Lyndex endmill holder went up to $84 right after I bought it. Weird.

Suncoast tools also sells Sowa.

The Lyndex Nikken 1/2" endmill holder is freakin amazing. 0.0003" run out at the shank and 0.0001" at the flutes on a stubby carbide endmill. The next endmill I put in this holder will vary so the run-out will vary, but the first endmill made it look awesome. Lol.

I can't buy another one for the same price. It's still $84 now.
