Boring Bar for Pulley
#8
Nice work! I especially like that style of insert. They are ideal for boring, in fact just what they were made for. The right hand version of the chipbreaker on those is something special for when you need very low cutting pressure, such as a longer small diameter bar or thin walled tubing. Valenite still offers both left and right in the TNMM negative rake style, chipbreaker designation PN-EL1 & 2 and the PN-ER1 & 2. The 1 is a tighter chipbreaker than the 2.
