Pafana NNBC 2516 S30 NOZ TOK.ISO 3 R — cutting tool holder ISO 3-sided, model ISO3R2516P30

Pafana NNBC 2516 S30 NOZ TOK.ISO 3 R is a cutting tool holder designed to accept ISO three-sided (triangular) indexable inserts. Supplied under the model ISO3R2516P30, this holder provides a rigid mounting platform for inserts used in turning and certain milling or profiling operations that use ISO-style triangular geometry. Its construction focuses on stable clamping, repeatable insert positioning and compatibility with toolposts and toolholders sized for the specified shank profile.

Advantages

The holder offers robust mechanical support for ISO 3-sided inserts, ensuring consistent cutting edge location between index changes. Its design simplifies insert replacement and minimizes setup time while maintaining repeatability across multiple assemblies. The clamping interface and insert pocket geometry are optimized to reduce vibration and improve cutting stability during moderate to heavy-duty metal removal. The product is compatible with standard tool mounting systems that accept its shank dimensions.

Suitable for

• Turning operations using ISO triangular indexable inserts
• Profiling and light milling tasks where an ISO 3-sided insert geometry is preferred
• Workholding setups requiring repeatable insert positioning and stable clamping
• General metalcutting on steels, cast irons and non-ferrous metals with appropriate insert grades

Key specifications

• Insert geometry: ISO three-sided (triangular) indexable inserts
• Orientation: right-hand (R) configuration for toolpost mounting
• Shank/profile: designed to fit compatible toolholders accepting this shank size
• Clamping: mechanical clamping system for secure insert retention
• Application: suitable for turning and certain milling/profiling operations
• Material compatibility: common ferrous and non-ferrous metals when used with appropriate inserts

How to use

Install the tool holder into the machine tool's toolpost or compatible mounting fixture that accepts the specified shank profile. Fit a correctly sized ISO three-sided insert into the pocket, ensuring correct orientation and seating against the locating surfaces. Tighten the clamping screw or mechanism to the manufacturer's recommended torque to secure the insert. Verify insert projection and tool height relative to the workpiece before machining. Index or replace inserts as they wear to maintain cutting performance and dimensional accuracy.

Usage recommendations

Use measured torque values for clamping to avoid insert or holder damage; select insert grade and geometry appropriate to the workpiece material and cutting parameters. Ensure the holder and machine setup provide adequate rigidity and tool overhang is minimized to reduce vibration. Regularly inspect the insert pocket and clamping surfaces for wear or debris and clean before insert installation.
