Tungaloy PNMU0905GNEN-MJ AH3135 Insert

DoPent Double-Sided 10-Edge | MJ Medium-Duty Chipbreaker | Made in Japan

What is the most cost-effective 10-edge insert for steel milling?

The Tungaloy PNMU0905GNEN-MJ AH3135 is a high-performance indexable milling insert belonging to the innovative DoPent series. This insert utilizes a unique pentagonal double-sided design, providing a total of 10 cutting edges, which significantly reduces the cost-per-edge for high-volume production. The AH3135 PVD coated grade is a specialized nanotechnology coating designed for high toughness and resistance to thermal cracking, making it the premier choice for steel and stainless steel face milling. Paired with the MJ chipbreaker for medium-duty applications, it ensures stable chip evacuation and low cutting forces even in interrupted cuts. This Japan-manufactured face milling insert is essential for modern CNC machining centers aiming for maximum efficiency.

Technical Specs: Metric vs. Imperial Conversion

ISO Parameter Metric Designation Imperial Designation
Inscribed Circle (IC) 15.875 mm 5/8 inch

Recommended Cutting Parameters (AH3135 Grade)

  • Cutting Speed (Vc): 80 - 220 m/min (Depending on material hardness)
  • Feed per Tooth (fz): 0.15 - 0.35 mm/t (Optimized for MJ breaker)
  • Machining Strategy: Dry cutting is recommended for steel to prevent thermal shock.

*Pro Tip: AH3135 is specifically designed for toughness. If you encounter edge chipping during interrupted cuts, this grade will significantly stabilize your process.*

Global Verified Customer Reviews

⭐⭐⭐⭐⭐ "Incredible Economy" - Dieter S., Germany

⭐⭐⭐⭐⭐ "Stable Surface Finish" - Kenji T., Japan
"Very low vibration on our face milling operations. The MJ breaker handles chips perfectly."

⭐⭐⭐⭐ "Great for Interrupted Cuts" - Robert L., USA
"We ran these through some heavy weldments. The AH3135 coating held up without any chipping. Very impressed."

⭐⭐⭐⭐⭐ "Long Tool Life" - Carlos M., Mexico
"We get significantly more parts per edge than with our previous 4-edge setup. Fast delivery from Japan."

⭐⭐⭐⭐⭐ "Reliable Performance" - David W., UK
"Genuine Tungaloy stock. The 10 edges are all consistently sharp. Excellent value for money."

Technical Tooling Q&A

Q: Is this insert better for roughing or finishing?

A: The MJ chipbreaker is designed for general medium-duty cutting, making it highly versatile for both roughing and semi-finishing in face milling.

Q: Which cutter body should I use with PNMU0905?

A: This insert is compatible with the Tungaloy DoPent series (TEN09/TPN09) face mills. Ensure you match the seat size 09.

Q: How does AH3135 compare to AH725?

A: AH3135 is optimized for higher toughness and thermal shock resistance, whereas AH725 is a more general-purpose grade. Use AH3135 for more demanding steel milling.

Expert Insight: Pentagonal Rigidity

In CNC face milling, the PNMU0905 series with AH3135 provides a strategic edge. The 10-edge design doesn't just save money; the pentagonal shape offers a more stable seating position in the cutter body, which dampens vibration and ensures precision machining even at high feed rates.

Technical FAQ & Buying Guide

How do I choose the correct specification?

When choosing CNC cutting tools, check the full model code, dimensions, grade and selected variant before ordering. Do not rely on the product image alone.

How can I check compatibility with my existing setup?

For carbide inserts, tool holders, drills and end mills, compare the mounting dimensions, connection type and manufacturer's specifications with your holder or machine. If you are unsure, share your existing part number and machining application with us before ordering.

What quantity and price unit am I ordering?

Check the product listing for the selling unit, pack quantity and included components. If it is unclear whether the price is per piece or per pack, or whether a tool body and inserts are sold separately, contact us before purchasing.

How should I choose cutting parameters?

Select cutting speed, feed rate and depth of cut using the relevant manufacturer's recommendations for your tool model, workpiece material, machine conditions and coolant method. The same settings are not suitable for every product or application.

Are bulk discounts available?

Our automatic quantity discount is 6% off for 2–9 items and 12% off for 10 or more items, based on the total product quantity in the cart. Other offers may not combine with this discount; check the applicable offer conditions.
