The body is constructed from hardened alloy steel with a black oxide finish and uses a top-clamp (pin-lock style) insert clamping system visible in the photos, providing rigid insert seating for heavy roughing and general turning operations. This holder is suited for OD turning on CNC lathes and manual engine lathes requiring a left-hand approach angle of 95°, compatible with Seco CNMG 432 series inserts including grades such as TP2501, TP3501, and TK1001. Manufactured in India per the box label, this is new old stock supplied in the original Seco plastic case with part number 6244855 confirmed on both the holder body and
