Customer Reviews for Lathe Chuck K11-80 80mm 3 Jaw Reversible Grinding Machine Jaws Adjustment

This mechanical chuck is a bit clunky. The materials, quantity and quality of machine work in this chuck yet produced at such a low cost and delivered to your front door, amazing. These economy tools often need some special TLC first for assembly. More for you buck. Take it apart and smooth deburr the sharp edges you will find most everywhere. A little lube on any bearing pin, Its a great 8 inch Chuck for the price. I installed an D4 adaptor plate on mine to mount on my 14 inch Lathe, This chuck may be too big for smaller lathes. Runs true enough, holds a 2 1/2 inch diameter material into the chuck hole. Machine handles it. Its a great chuck for the price, not my choice for production in a machine shop, but good enough for a home hobbyist. Soft jaws and everything runs perfect..

This item completed my home built roll out wheel. Excellent tool. Value for the price and exceptional quality.

Would buy again. It's not a high precision chuck- but better than a good used one. Mounting holes tolerance was 0.2 mm out. But it was spinning OK to do useful work. Jaws close a bit rough. But it has 3 tightening spots. Tighten on all 3 equally and it grips and centers OK. I fitted it to a wood lathe (which is rough and wobbly by comprison to any metal lathe) and the chick performs a little bit better than most timber chucks. It would have been nice to have woodlathe fixing holes at the back of the chuck. The way it is... mounting it on a timber lathe was frustrating and took forever. On a metal lathe it would be quite fast- but still needs centering. I got it to run on a 250 microns- wobble which is ok ok for a rough turning woodlathe. On a metal lath this is boarderline- but better than a good used chuck. The chuck gears were ground a bit rough- but then its not a $500 chuck..... :) Grip and centering is ok when you tighten all three equally. For hobby use its perfectly ok. For precission work (my German lathe runs on (0 microns) its not suitable. Value / performance is ok for the price :) recommend to buy it for simple hobby level work! or go spend $500 + for a perfect one or if you have time to fiddle with it - it will do on a metal lathe lol :)

I'm not really using it for the standard purpose but it functions as the original on my lathe should. No issues opening and closing it I cleaned and relubed it as I would suggest anyone do when buying anything metal on metal that moves like vices slides ect.

Works excellent accurate for my needs easy to use and maintain 1.5 thousands excellent accuracy too

Sent back order by mistake

I used the 6” on a welding positioner I made and was able to get it within .002, which is just fine for what I need.

Turned down the new backing plate to fit this 5 inch Chuck and brought it back to less than 2 thousandth run out on the dial indicator. I was very nervous to try this (absolute amateur) but it came out well. The tightening sequence of the backing plate bolts was the key, set up a dial indicator on a nice round part like a drill bit shank, turn the chuck to find the high spot tighten the variance out, repeat. My old chuck was 90 thousandths plus out, so happy with the new one.

Unlike previous chucks this model I have had , this one has 3 bolts to fix it . After making a new face plate all the dial gauge tests came up concentric. The quality for the pice makes this a good buy. I would recommend the chuck.

good service and quality product..................................................................................................................
