10 Things to Consider When Buying R 8 Collet

Only way thats going to hold anything against cutting forces is if you tap tight fitting sleeve, or better, shrink fit, over the extended part after you've put the cutter in.

A semi permanent job. Which might be worth it if you have a suitably hefty cutter, flycutter, boring head or whatever on a 25 mm shaft sitting around doing nowt.

Considerable risk of the collet snapping where the taper runs out into the extended part.

Better to get a sidelock (weldon) holder and grind a flat on the cutter. At least the holder is all solid.

Although I have full sets of R8 in both imperial and metric I'm rapidly coming to the conclusion that sidelock is the better way for plain shank cutters. But Clarkson is my general purpose go to as I have plenty of screwed shank cutters.

My X2 is in pieces at the moment (I need to clean off the red packing grease), but when I measured the T-slot opening in the table, I got values of approximately 11mm for the slot opening width.

The HF clamping kit at

The LMS clamping kit at

Both clamping kits use 3/8" studs.

So, are both kits good to go for the X2 table, or will the HF T nuts or clamps need to be milled down by a mm to fit?

I think that I bought the LMS kit, but I have temporarily misplaced it among all of the tooling and accessories that I got for my mini mill and mini lathe, so I can't actually measure or check it right now...

Slightly OT, but a quick note about the clamping kit... Maybe someone else with an X2 can chime in.My X2 is in pieces at the moment (I need to clean off the red packing grease), but when I measured the T-slot opening in the table, I got values of approximately 11mm for the slot opening width.The HF clamping kit at 58 Piece Combination Step Block and Clamp Set - 3/8"-16 NC Studs, 1/2" Clamps makes reference to 1/2" table slots. Since 1/2" is approximately 12.7mm, I'm wondering whether the HF kit is OK for use with the X2.The LMS clamping kit at LittleMachineShop.com - Clamping Kit, 7/16" T-Slot claims that it is for 12mm slots, and it is described as a clamping kit for 7/16" T-slots. I believe that 7/16" equates to just over 11mm.Both clamping kits use 3/8" studs.So, are both kits good to go for the X2 table, or will the HF T nuts or clamps need to be milled down by a mm to fit?I think that I bought the LMS kit, but I have temporarily misplaced it among all of the tooling and accessories that I got for my mini mill and mini lathe, so I can't actually measure or check it right now...
