I made a tangential toolholder to one of the designs published in MEW. It worked so well that I made one for 5/16" HSS toolbits. It is so good that it sees a lot of use, for Facing or Turning without any restting.
(A holder for the unused 100 degree corners of CCMT0604 bits is used for roughing) The 5/16" bit seems to cope quite happily with anything from a 0.050" cut to a 0.0005", and with a feed rate of 0.0023"/rev gives a good surface finish.
And, unlike carbide tips does not chip and is easy to sharpen. No problems with the bit being pushed down. Easy to set tool to a home made centre height gauge.
SO impressed that I even wonder about buying the Eccentric Engineering product, to see if it is even better!
Other members of our M E club have made them, and been so pleased that they have made Left Handed versions.
My use of carbide tips has greatly decreased, so may provide a financial justification for the commercial product.
