DVJN tool holder (DVJNL 2020) – for VN-- 1604 indexable inserts, 93° approach geometry (Teknik Makina)

The DVJN for VN-- 1604 Indexable Inserts is a left-hand turning toolholder engineered for secure clamping and consistent approach geometry in CNC and lathe operations.

• 93° approach geometry for reliable cutting
• Compatible with VN-- 1604 indexable inserts
• Overall length 125 mm for compact setups
• Secure clamping, 20 mm holder width

Greater process security through defined approach geometry

The holder provides a 93° cutting angle, which creates a controlled engagement between insert and workpiece. This geometry reduces radial loading and helps to stabilise the cut in left-hand turning operations, delivering more predictable tool life and surface finish. The combination of 40 mm cutting height and the defined approach assists in consistent chip evacuation, which is particularly useful in repetitive turning tasks where repeatability is critical.

Repeatable clamping and compact design for efficient setup

Designed with a 20 mm holder width and a 27 mm cutting-head width, the toolholder is balanced for compact tool stacks and easy access in confined turret stations. The ISO designation DVJNL 2020 denotes compatibility with common mounting standards, and the solid construction ensures secure clamping of VN--type inserts. With a weight of 0.428 kg, the unit is light enough to reduce turret inertia while remaining rigid for production use.

Simple integration with existing tooling and inserts

Compatibility with VN-- 1604 indexable inserts means standard insert stocks can be used without modification, lowering tooling variety and spare-part inventory. The shank/boring-bar reference K16 and overall length of 125 mm permit straightforward installation in many turning tool posts and turrets. The left-hand orientation is specified for counter-clockwise feed directions, ensuring correct tool geometry when combined with standard turning programmes.

Reliability for everyday workshop and CNC use

The construction focuses on durability and straightforward operation: robust clamping, standard ISO form, and compact dimensions support frequent insert changes and predictable maintenance intervals. The precise approach geometry contributes to consistent results across runs, reducing scrap and the need for rework. The holder is suitable for both manual lathe setups and automated CNC environments where dependable performance is required.
