TCGT16T304-MN2 WNN10 – Drill/boring indexable insert and turning indexable insert, 60° triangle, coated carbide — Walter Tools

TCGT16T304-MN2 WNN10 is an indexable insert designed for drilling, boring and finishing operations where predictable chip formation and a stable cutting edge are required

• Coated carbide grade WNN10
• MN2 chipbreaker for stable chips
• 60° triangular insert geometry
• 0.4 mm corner radius, 7° clearance

Increased productivity through a durable cutting edge

The combination of WNN10 (coated carbide) and the MN2 chipbreaker is engineered to extend tool life while maintaining process stability. The coating improves wear resistance under cyclic loads, which reduces the frequency of index changes and supports consistent cycle times. As a result, machining operations can run longer between interruption, and setup times are reduced. This translates into measurable gains in throughput for repetitive production tasks.

Predictable chip control that protects the workpiece

Reliable chip formation is essential for safe drilling and boring; the MN2 chipbreaker promotes short, controllable chips that evacuate cleanly from the hole and reduce re-cutting. With the insert’s 60° triangular geometry and a 0.4 mm corner radius, the cutting edges deliver consistent engagement and a predictable cutting footprint. The outcome is improved surface quality and fewer interruptions due to chip-related issues, which supports higher first-pass yields on production runs.

Design details that lower machining risk

A 7° clearance angle and the insert’s T3 thickness contribute to a balanced edge strength and clearance combination. The modest clearance reduces rubbing while preserving a robust cutting edge capable of withstanding axial and radial loads typical in drilling and light turning. The triangular shape provides three usable cutting corners, improving cost-efficiency per edge and simplifying index strategies for batch work.

Application guidance and material considerations

The insert is specified in the Walter cutting material series - open and the WNN10 grade is a coated cemented carbide variant; verify the material suitability against the manufacturer's product matrix for the target workpiece material. The G tolerance class indicates manufacturing precision of the insert seating and can enhance repeatability in toolholders. For best results, pair the insert with holders rated for triangular 60° geometry and follow recommended cutting parameters for feed and speed based on the workpiece material.

FAQ

What operations is this insert intended for?
The TCGT16T304-MN2 WNN10 insert is designed for drilling, boring and light turning operations where a stable cutting edge and effective chip control are required.

How does the MN2 chipbreaker affect performance?
The MN2 chipbreaker promotes short, controlled chips that aid evacuation from holes and reduce re-cutting, enhancing surface finish and process reliability with the Walter Tools insert.

Which workpiece materials suit the WNN10 grade?
WNN10 is a coated cemented carbide grade; material suitability should be checked against the Walter Tools product matrix to match grade properties with the specific workpiece material.

How many usable cutting edges does the insert provide?
The triangular 60° geometry offers three cutting corners per insert, improving per-edge economy and simplifying index strategies for batch production.

What does the tolerance class G mean for machine setup?
Tolerance class G denotes the manufacturing precision of the insert seating; tighter tolerances support repeatable positioning in the toolholder and contribute to consistent machining results.
