Tungaloy's full profile threading inserts; 4 cutting edges
The TetraMini-Cut insert comes in a compact profile with four cutting edges. Its insert clamping ensures high repeatability, accuracy, and tool life. The full profile threading insert mounts on existing standard TetraMini-Cut toolholders for 60° V-profile or grooving inserts. Since the insert cuts a complete thread profile including the crest, no deburring is need. An optimized tool design provides minimal interference when turning towards the tailstock of the lathe. Inserts are offered in two grades: SH725 for free cutting of fine pitch threads in small diameter bores and AH725 for universal threading applications on Swiss-type and general lathes; applicable for thread pitches ranging from 0.5mm to 1.5mm of external ISO metric threads.
