TCGT 16T304 NS9530 Wendeplatten - Tungaloy

Best suited where high-quality surface finish and low cutting forces are required: the combination of an uncoated cermet grade (NS9530) with a 0.4 mm nose radius delivers consistent finishing performance for continuous turning operations, while the ISO form and standard hole geometry ensure straightforward compatibility with standard holders and clamping systems.

TCGT 16T304 NS9530 ISO turning insert for finishing by Tungaloy

The TCGT16T304 NS9530 is an ISO-standard triangular turning insert designed for finishing cuts on steel, offering a sharp cutting edge and low cutting forces for continuous cutting and small depths of cut.

• Uncoated cermet grade NS9530
• 0.4 mm nose radius for fine finishing
• 7° clearance angle for low cutting forces
• Triangular form with cylindrical hole and countersink
• 3.97 mm plate thickness suitable for ISO holders

High-precision finishing for steel turning applications

The insert’s uncoated cermet composition, designated NS9530, is engineered specifically as a finishing grade for steel, providing a sharp cutting edge and reduced cutting forces that favour continuous cuts and improved surface quality. Cermet combines ceramic and metallic phases to deliver superior wear resistance and stable edge retention during light, high-rpm finishing operations; this results in a consistently finer surface finish compared with many general-purpose grades. For applications where a smooth part surface and tight tolerances are required, the combination of the 0.4 mm nose radius and the sharp edge geometry supports repeatable results with low tendency for built-up edge.

Secure clamping and ISO compatibility for reliable machining

Compatibility with clamping systems depends on form, clearance, tolerance class, fastening, size and thickness; the triangular ISO form and the standardized hole arrangement — cylindrical hole with a single-sided countersink (40°–60°) — permit use with common external holders and boring bars that accept ISO turning inserts. The insert’s 3.97 mm plate thickness and nominal size 16 provide the mechanical support required for finishing operations while the 7° clearance angle reduces rubbing and minimises cutting resistance. When configuring the system, ensure the correct holder geometry and appropriate shim or clamp set; the system concept comprises the ISO insert, a matched external holder or boring bar, a support shim or clamp set and replacement screws.

Operational benefits and application guidance

Designed for finishing on steel with small depths of cut, the grade excels under continuous cutting conditions where a steady chip flow is maintained. The single-sided chipbreaker helps control chip formation for short, consistent chips at low to moderate feed rates, reducing the risk of surface damage and easing part handling. For best results select a stable machine setup, rigid clamping and cutting parameters matched to light finishing passes. The insert’s geometry and grade favour high surface quality and reduced rework, making it suitable for precision components where dimensional accuracy and finish are priorities.

FAQ

What materials is this insert intended for?
The TCGT16T304 NS9530 is a finishing grade optimised for steel; the uncoated cermet composition provides a sharp cutting edge and good surface finish in continuous turning operations.

Which holders are compatible with this ISO insert?
Compatibility is determined by form, clearance angle, tolerance class, fastening, size and thickness; use a holder or boring bar designed for ISO triangular inserts of size 16 and plate thickness 3.97 mm.

How does the 0.4 mm nose radius influence the finish?
A 0.4 mm nose radius produces a finer surface and reduces stress concentration at the tool tip, supporting high-quality finishing passes at modest feeds.

Is the insert suitable for interrupted cuts?
The grade is primarily intended for continuous finishing; interrupted cuts may require a different geometry or a tougher grade to withstand impact.

What is the hole geometry and why does it matter?
The insert features a cylindrical hole with a single-sided countersink (40°–60°), a standard arrangement that ensures secure clamping in compatible ISO holders.
