Sandvik Coromant 5742014 Threading Toolholder Internal 5/8 Inch

Product Description

The SANDVIK COROMANT 5742014 is an internal, right-hand indexable threading toolholder designed for precision thread-turning operations on CNC lathes and turning centers. Built from steel and part of the T-Max U-Lock 166 series, it accepts 1/4 inch inscribed circle inserts secured by screw clamping. The 5/8 inch shank diameter and 16 mm minimum bore diameter make it suitable for internal threading in a range of bore sizes. With an overall length of 6 inches and a pitch range covering 32 to 12 threads per inch, this holder serves production threading applications that demand consistent insert indexing and rigid setup.

This toolholder is intended for internal threading on production turning equipment in machine shops, tool rooms, and manufacturing facilities. It is installed by machinists and CNC operators performing thread-turning on lathes with appropriate boring bar setups. The screw-lock insert holding method provides reliable clamping during continuous threading passes. The maximum depth of cut reaches 1.875 inches, and the head length measures 1.03 inches, making it useful for moderate bore depths in ferrous and non-ferrous workpieces.
