Earl Diamond Super Heavy Duty 1/2" Drill Chuck with Chuck Key and MT2 Shank | Morse Taper Arbor #2 (B16)

Not sure what some are complaining about with regard to the drill bit size. The Earl Diamond Super Heavy Duty Drill Chuck 1/2" Capacity with MT2 Morse Taper 2 Arbor & K32 Key (B16) listed here that I bought, has no problem holding pretty much any drill bit up to 13mm. Just over 1/2". Chuck indicates 0.5mm ~ 13mm. 1mm is .03937". A 0.5 mm drill bit (as listed on the side of the chuck) is 0.01968 inch. Who has a drill bit smaller than that? If you did, you probably wouldn't expect a 1/2" drill chuck to make watches Just saying. These jaws almost close tight. When you hold this chuck up to the light before putting it onto the mandrel, can barely see light thru it. Very accurate and very smooth. The only complaint I had, was that I used a micro file on the tips of the three jaws in order to get rid of a very minute finishing burr. This in no way effected the fit and function of the drill chuck or what size drill it accepted. Very well made. Tight and smooth. No regrets. If I needed two, I would definitely buy another. Shoot Straight Choose Wisely

Works well on my Jet lathe 1224.

I use this in a Delta 46-460 lathe. Fits into the tail stock properly. Well machined, good finish on the metal. Works smoothly. Have had no problems with it at all.

Love it, only one problem. The end of the MT2 taper has a tang and not a drilled and tapped hole. Need the hole to allow the chuck to be used safely in my lathe headstock without a support in the tail stock. In fairness, the images show a tang and I should have noticed it before I bought the chuck.

I was impressed by the quality/price ratio.

I use this on my wood lathe, holds bits well, and as intended

The arbor and chuck came in an Earl Diamond box, but they were stamped with "Sandu". Also, the runout on the chuck was as bad as the cheap original one I replaced at .015" It's a nice looking chuck and works, but I needed better accuracy (no more than .005) for small bits.

If you plan on using this chuck on the tail stock instead of the head stock, you will have to saw off the end of the shaft. I did and it works just fine!
