TUNGALOY 16ER 1.0ISO-B AH725

External ISO Metric Specialist | 1.0mm Pitch | AH725 Nano-PVD Grade

Product Overview

The Tungaloy 16ER 1.0ISO-B AH725 is a high-precision external threading insert designed for 1.0mm pitch ISO metric threads (standard for M6 and M7 fasteners). This indexable carbide insert features the world-renowned AH725 PVD coated carbide grade, providing the edge toughness and heat resistance necessary for demanding CNC machining tasks. The "-B" chipbreaker geometry is specifically engineered to manage chip flow during external threading, preventing scratches on the workpiece and ensuring a clean, accurate thread profile. Made in Japan, this insert is the industry standard for precision machining in stainless steel, carbon steel, and alloy steel.

Inscribed Circle (IC) 9.525 mm 3/8 inch
Application M6 x 1.0 Coarse Standard Fine/Coarse mix

Pitch Selection Guidance: The 1.0ISO is a Full Profile insert. This means the tool forms the complete 60° thread—crest and root included—in one operation. This is critical for external threading as it guarantees exact minor and major diameters, ensuring perfect interchangeability for M6 fasteners.

Material: AH725 PVD High-Grade Carbide

The AH725 grade is Tungaloy's premium choice for stainless steel turning and threading. It features a micro-grain substrate that resists chipping, paired with a nano-multilayered PVD coating for heat resistance. This long-tail keywords industry favorite ensures stable tool life and exceptional surface quality even in difficult-to-cut superalloys.

-B Geometry: Advanced Chip Control (槽型)

External threading often faces the challenge of long, bird-nesting chips. The -B chipbreaker geometry is engineered to curl chips tightly, breaking them into manageable pieces that fall away from the tool post. This protects the precision machining results and allows for safer, automated CNC cycles.

Recommended Cutting Parameters

Optimized for P (Steel) and M (Stainless Steel):

  • Cutting Speed (Vc): 90 - 180 m/min (295 - 590 SFM)
  • Total Radial Depth: 0.61 mm
  • Number of Passes: 6 - 10 passes

*Pro Tip: For M6 threads, ensure your machine spindle is running at a stable RPM to maintain consistent surface finish across the thread profile.*

Global Verified Reviews

⭐⭐⭐⭐⭐ "Standard for M6 bolts" - Hans L., Germany
"Consistent 1.0mm pitch results. The AH725 grade lasts significantly longer in stainless than standard carbide."

⭐⭐⭐⭐⭐ "Great toughness" - Hiroshi M., Japan
"Using this on alloy steel. Excellent tool life and mirror-like finish on the external threads. Original quality."

⭐⭐⭐⭐ "Chips break perfectly" - David R., USA
"The -B chipbreaker really does make a difference in external work. No more stopping the lathe to clear chips."

⭐⭐⭐⭐⭐ "Highly Recommended" - Luigi C., Italy
"Surface finish is top-tier. Fast delivery and authentic Tungaloy packaging. Excellent for high-precision jobs."

⭐⭐⭐⭐⭐ "Reliable Tooling" - Sarah P., UK
"Consistent performance over hundreds of parts. Fits our SER tool holders perfectly."

Technical Q&A

Q: Which tool holder does this fit?

A: It fits all standard **SER** external threading holders with a size 16 pocket (3/8" IC), such as the **SER2020K16**.

Q: Can I use this for internal threads?

A: No. This is an **ER** (External Right) insert. For internal threading, you must use the **IR** series.

Q: Is AH725 good for Titanium?

A: Yes! AH725 is a high-toughness PVD grade designed for steel, stainless, and heat-resistant superalloys like Titanium and Inconel.

Expert Machining Tip: Grade Selection

For external threading, PVD grades like **AH725** are superior to CVD grades because they maintain a sharper cutting edge. This sharpness is essential to prevent "tearing" the thread profile in softer materials, leading to superior accuracy and longer tool life.

Technical FAQ & Buying Guide

Are your carbide inserts interchangeable with major brands like Sandvik, Iscar, or Kennametal?

Absolutely. Our CNC carbide inserts (including CNMG, WNMG, DNMG, and APMT series) are manufactured strictly adhering to international ISO/ANSI specifications. A CNMG 120408 from OYYU BEYOND will flawlessly fit any standard turning tool holder or indexable tool from major global brands like Sandvik Coromant, Kennametal, Iscar, Walter, or SECO, providing a highly cost-effective premium alternative without sacrificing tolerance or tool life.

How do I choose the correct insert grade and chipbreaker for machining Stainless Steel (M) vs. Carbon Steel (P)?

We offer optimized CVD and PVD multi-layer coatings for different ISO material groups:

  • For Carbon/Alloy Steel (ISO P): Choose our thick multi-layer CVD coated grades (e.g., Al2O3 + TiN). They provide exceptional crater wear resistance and thermal barriers during high-speed dry or wet roughing.
  • For Stainless Steel (ISO M): Choose our nano-structured PVD coated grades with sharp, positive chipbreakers (like -TM or -MA). This combination prevents work hardening and effectively controls sticky chips.
What are the recommended cutting speed (Vc) and feed rate (f) parameters to maximize tool life?

The optimal cutting parameters vary depending on the workpiece hardness and operation type:

  • For General Steel Turnings: Recommended cutting speed ($V_c$) ranges from 150 to 280 m/min, with a feed rate ($f$) of 0.15 to 0.45 mm/rev.
  • For Stainless Steel Finishing: Recommended cutting speed ($V_c$) is 120 to 200 m/min, with a feed rate ($f$) of 0.10 to 0.25 mm/rev.Always adjust parameters based on early wear patterns: increase $V_c$ if built-up edge occurs, or reduce $V_c$ if severe flank wear is observed.
Do you offer bulk discounts or wholesale pricing for machine shops and distributors?

Yes, we support machine shops, distributors, and global buyers with tiered wholesale pricing and competitive volume discounts. We also provide OEM custom manufacturing solutions for tool holders and carbide inserts based on your technical drawings. Contact our team to request a quick B2B quotation.

What is your international shipping policy and typical lead time for orders?

We provide secure worldwide express shipping (via DHL, FedEx, and UPS) with specialized, vibration-proof industrial packaging to ensure tools arrive in perfect condition. In-stock items are dispatched within 24-48 hours, while custom or bulk orders typically have a stable lead time of 15-25 days.
