### ⭐⭐⭐ 







  
  
    They OK, but have seen better from CMT
  

*by K***N on Reviewed in the United States on December 19, 2015*

I bought various sizes of CMT Mortise Chisel bits for my Mortising machine. The bits are accurately machined and pretty rough on the outside. I spend about 30 minutes per chisel to polish the chisel but some machine marks were so deep that I could not remove them. After polishing I also sharpened the chisel. The Auger had also many machine marks and I spend 15 minutes per auger to remove the marks and also trim the cutting edges which protruded slightly above the edges of the chisel and caused light drill marks inside the mortise.After this initial tuning the bits are performing good. The bits are holding sharp edges well and eject chips good without any overheating. I wish CMT could decide if they are building long shaft or short shaft Augers though. The 1/4" Mortise chisel and a few sizes up, they are long shaft, but larger sizes like 3/4" and 1" are short shafts. This is not really convenient if one needs to change sizes often, as it requires me to remove the chuck from the Mortiser to put a spacer in for short shaft chisels, and remove it for short shafts.Would I buy them again? I would take a look at Powermatic chisels and Lee Valley before making the decision.Pictures below show chisel how before and after polishing.

    Good quality.
  

*by J***K on Reviewed in the United States on May 9, 2015*

Shank was 1/16 larger than the delta mortising  attachment.Since in needed 5/8" and only CMT (not Delta) had one, I drilled out the cast iron attachment to accept this one.Would have been 5 stars had it been compatible with the delta out of the box.

### ⭐⭐⭐ 







  
  
    Reasonable Good
  

*by D***N on Reviewed in the United States on March 2, 2011*

These chisels are reasonably good and fairly sharp as received. I was slightly disappointed with the overall finish as the chisel needed substantial honing to remove the grinding marks from the business end. Once the chisel was honed, slight touchup with a diamond cone on the inside of the chisel and some slight sharpening of the auger, it was ready for use. Once 'tuned up' the chisel works very well, I cut over 100 mortises in hard maple and it is still going strong.
