Lathe Tooling Gallery
The tool holders depicted below are all of the BXA or 200 size import wedge lock style that I use on the PM1440.
Parting tool holder the comes customary with the generic 5 piece set. P3 type HSS parting blade ground with a slight right bias. Curls the steel up at 70 rpm.
HSS ground 3/16 radius cutter for a one off job.
1/2″ diameter “boring bar”. For this reason I am only buying the “turn and face #2” holders. 250-202 part number.
The customary knurling tool included with the 5 piece set. At 70 rpm and lots of oil it does a serviceable job. Shars MTVOR12-3B 3/4″ insert holder (404-1813) sporting a TNMC 32NGR062 Tin 1/16″ wide grooving insert (424-0722). I indicated the cutting surface to within a couple thousandths from lathe centerline of the threading tool below to cut the groove at the end of a blind thread. Tool holder was opened up to accept the 3/4″ shank. Older Dorian Tool MTVOR12-3B 3/4″ insert holder with cheap Shars TPMA 32NV Tin (424-0806) threading insert. This tool holder was also opened up to accept the 3/4″ shank. Didn’t make sense to me to mill down a $70 insert holder to fit a $18 tool holder. Ground HSS insert for turning. Ground HSS insert for turning and facing as suggested in Tom Lipton’s book “Metalworking: Doing it Better” Dorian Tool MCLNR12-4B insert holder with Iscar CNMG 431-GN Grade IC9250 – Turning Insert
