TUNGALOY 11IR 1.5ISO-B AH725

Internal ISO Metric Specialist | 1.5mm Pitch | AH725 Nano-PVD Grade

Product Overview

The Tungaloy 11IR 1.5ISO-B AH725 is a high-performance internal threading insert engineered for 1.5mm pitch ISO metric threads (the standard for M10 and M11 coarse threads). This indexable carbide insert utilizes Tungaloy's signature AH725 PVD coated carbide, a grade specifically optimized for high-reliability CNC machining in stainless steel, carbon steel, and difficult-to-cut superalloys. The "-B" chipbreaker geometry is essential for internal threading, where space is tight; it tightly curls chips to ensure they are easily flushed out of the bore by coolant. For precision machining where profile accuracy and surface finish are paramount, this Japanese-manufactured tool is the industry benchmark.

Pitch Selection Guidance: The 1.5ISO is a Full Profile insert. This means it forms the complete 60° thread, including the root and the crest. By using a full profile tool, you ensure the thread depth and crest radius are perfectly within ISO specifications, eliminating the need to deburr or manually adjust the bore diameter after threading.

Material: AH725 High-Toughness Carbide

The AH725 grade is Tungaloy’s premier PVD coated carbide solution. It features a micro-grain substrate that resists chipping, paired with a nano-multilayered coating for heat resistance. This long-tail keywords industry favorite is designed for stainless steel turning and threading, ensuring high tool life even in unstable or interrupted cutting conditions.

-B Geometry: Internal Chip Control

In internal threading, chips often get trapped between the tool and the workpiece. The -B chipbreaker (槽型) features a high-rake angle and an optimized chip pocket that forces chips to break small and curl away from the thread flank, protecting your precision machining results.

Recommended Cutting Parameters

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

  • Cutting Speed (Vc): 80 - 150 m/min (260 - 490 SFM)
  • Total Radial Depth: 0.92 mm
  • Number of Passes: 8 - 14 passes

*Pro Tip: For 1.5mm pitch, use a modified flank infeed (29°) to reduce tool pressure and prevent chatter in deep bores.*

Global Verified Reviews

⭐⭐⭐⭐⭐ "Standard for our M10 Parts" - Thomas L., Germany
"Consistent 1.5mm profile and excellent tool life. The -B chipbreaker is vital for stainless work."

⭐⭐⭐⭐⭐ "Great toughness in Alloy Steel" - Hiroshi T., Japan
"AH725 handles interrupted cuts very well. Very sharp edges and mirror finish on the internal threads."

⭐⭐⭐⭐ "Reliable Performance" - Mark S., USA
"Original Tungaloy. Fits my SNR holders perfectly. Fast shipping and great wholesale price."

⭐⭐⭐⭐⭐ "No more chip nesting" - Luca G., Italy
"The chip control is impressive. We no longer have to stop the machine to clear the bore during production."

⭐⭐⭐⭐⭐ "High Precision" - Ben H., UK
"Cleanest threads we've seen on our CNC lathes. Definitely worth the investment for high-precision jobs."

Technical Q&A

Q: Can I use this for external threads?

A: No. This is an **11IR** (Internal Right). For external threading, you need the **11ER** series.

Q: What tool holder do I need?

A: It fits any boring bar with an 11-size pocket (1/4" IC), such as the **SNR0010K11** or **SNR0013M11**.

Q: Is it suitable for Titanium?

A: Yes. The **AH725** grade is a high-performance PVD carbide that excels in heat-resistant superalloys like Titanium and Inconel.

Expert Machining Tip: Grade Selection

For internal threading, always prioritize PVD grades like **AH725** over CVD grades. PVD coatings allow for a sharper cutting edge, which reduces cutting forces and prevents the "tearing" of threads in gummy materials like stainless steel.

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.
