I purchased SGIH 19-2 Part-off Blade for AP200 & PTNT 20 Parting Inserts 19mm high, SLTBN10 Part Off Block 10mm Tool Post for 19mm high Blade and AP200 UM25 Part-off - Parting Inserts 2.1mm PVD Coated for General Use as a set for machining crankshafts for model internal combustion engines.
Initially the wrong inserts were supplied (both had UM25 in the part number) but this was quickly rectified by Jim at APT.
As a hobby user I am happy with the products. The parting blade is more rigid than the normal HSS ones and greatly reduced the chatter with the large overhangs necessary for turning crankshafts.
