I have a dremel which I used to mill pine logs when rebuilding our house which was damaged by fire in 1912. I bought a few sets of HSS titanium bits but found them virtually useless after cutting a few inches of soft pine. I tried making a 3/8" channel 3/4" x 5" deep and they just lost their edge after a few inches. With little pressure and only 1/8" deep per pass it was never mind they seemed just decorative toys these hozly beats are the real deal soft jaws they cut like warm butter they work very well in the dremel just remember to use a wrench to tighten the chuck.
