Walter 6349852 Lh Dtjn Negative Rake Indexable Turning Toolholder

Product Description

The WALTER 6349852 is a left-hand DTJN-style indexable turning toolholder designed for precision external turning operations on CNC lathes and turning centers. Built to ANSI and ISO standards, it features a 1.25-inch square shank and accepts negative-rake inserts with a rake angle of -6 degrees. The clamp-style insert holding method provides rigid, repeatable seating, making this toolholder suitable for interrupted cuts and general turning applications where consistent tool positioning is critical. Licensed machinists and CNC operators working in metalworking and machining environments are the primary installers and users of this toolholder.

The 6349852 is intended for use in turning applications where left-hand cutting direction is required. It is compatible with TN..2706.. and TN..54.. series inserts, covering a range of insert sizes with a 5/8-inch inscribed circle. It is part of the Walter Turn series and is appropriate for both production and job-shop environments running ferrous and non-ferrous materials. The toolholder is designed for use without coolant-through capability, making it suited for standard external turning setups.
