Sandvik Coromant 5731022 Indexable Turning Toolholder DDJNL204D

Product Description

The SANDVIK COROMANT 5731022 is a left-hand indexable turning toolholder in the DDJNL style, designed for use with DNMG 432 inserts secured by a wedge clamping method. The toolholder features a 1.25 x 1.25 inch square steel shank and an overall length of 6 inches. It carries a negative rake angle of -6 degrees, which suits heavy interrupted cuts and general turning applications. Built for facing operations, this toolholder is installed by machinists and CNC lathe operators in production and job-shop environments where consistent insert indexing and rigid clamping are essential.

This toolholder is suited for facing operations on CNC lathes and manual turning centers. The wedge clamping mechanism provides secure insert retention under high cutting forces. With a head length of 1.55 inches and a back-of-bar to cutting edge distance of 6 inches, the 5731022 fits standard tool turrets and square shank tool blocks common in production turning setups. Its multi-use designation allows it to handle a range of turning applications where DNMG 432 geometry inserts are appropriate.
