The above code example describes a right-hand side, internally cooled carbide boring bar with a shank diameter of 3/4", a functional length of ~10" (250mm, long version), and a tool angle of 95°. The insert is held with a screw. It has an indexable insert with 35° corner angles, 7° clearance angle and ~13mm (0.5") cutting edge length.

Sharpening Handbook Metal Lathe Tools : Boring Bars Angles shown are good for hobbyists; grinds for production shops should consult a specialist. When both a relief and a clearance

Carbide Boring Bar Brazed It does have a cutting speed of 2.5 to 5 times that of HSS. This lathe boring technique implies it can withstand a lot of heat. Metal has a stiffness factor of 2.5 times that of brazed carbide. However, as the sharp edges of this form of boring lathe wear out, it must be reprocessed (that is very hard) or destroyed.

5/12 · The side clearance angle is very important but much depends if the cutting edge of the boring bar is on center, below center or above. When in doubt above center is best.

6/22 · The OD of the bar itself should be on center. Rotate the bar until the insert cutting tip is on center. The insert top face will now be negative and the heel clear should be correct. Where you went wrong was setting the insert top face flat since you had no orient flat on the bar and flat to the world makes the most logical sense.

Large Boring Bar Diameter : If the diameter of the boring is to large, there will be no clearance between the bore diameter and the boring bar body,

Chattered and noaned in the cut of course. So a quick touchup with the "tool grinder" made the boring bar actually work. 5° clearance angles and just a tad under square. You can't really see in the pictures but most of the set had the carbide actually over square so cutting to a square bottom would be a problem.
