  • Great arbor. Great price.
Style: 1 pc
Been working great on a right angle die grinder for over a year. I use it with a grinding wheel for breaking motorcycle chains in a professional shop. Daily use. Hasn't worn or slipped yet. Very durable and quite affordable. Fit perfect too. Can't ask for much more than that!

  • Good decent mandrel
Style: 1 pc
Slowly adding to the collection of cutoff tool accessories and this 3/8 arbor mounting mandrel has come it handy at times. So far seems to be of adequate quantity and held cutoff wheels securely in place. Hopefully it remains durable. Worth a try if you have the need. Okay pricing.

This is a great product design which comes in handy with heavy duty usage. This fits the Dewalt Pneumatic Die Grinder (DWMT70783) like a glove. I would recommend this quality product.

  • Must have for cutoff wheels

I use this in conjunction with the EZARC wheels i purchased. The reason I went with this one because you can use a wrench to tighten it up.

  • Value

The 3/8 mount don't hold the cutting or grinding wheel securely to the mandrel but it is durable for the value of the product and the thickness of the shaft is perfect fit

  • Very accurate

That outside of a little rust in the threads, it is accurate and runs true. Would be nice if they would do better metal protection against rust.
