Product catalog summary

Threading Application Guide Overview
This document serves as a comprehensive guide on threading applications, focusing on both fine and coarse pitch threading in cresting (full profile) and partial profile forms. It specifies the maximum and minimum threads per inch (TPI) for UN and ISO standards, addressing various threading needs.

Top Notch Threading System
The Top Notch Threading system is noted for its versatility and superior performance in heavy-duty applications, such as machining Acme, Buttress, and API threads. It offers a wide selection of insert geometries and grades, ensuring high tool life and quality surface finishes. The system simplifies operations by eliminating the need for shim selection and reducing inventory through compatible toolholders and boring bars.

Precision-Ground Thread Form
This section highlights the benefits of precision-ground thread forms, which minimize built-up edge, reduce cutting forces, and ensure accurate, high-quality threads.

Superior Chip Control
Top Notch threading inserts provide excellent chip control, eliminating long coils and being particularly effective for internal threading operations. Partial profile inserts are available for 60° thread forms.

5 Easy Steps to Maximize Productivity
The document outlines a five-step process for selecting the appropriate threading method, insert, grade, speed, and holder. It includes recommendations for grade and speed selection based on workpiece material and provides examples for practical application.

Catalog Numbering System
A detailed explanation of the catalog numbering system is provided, helping users identify specific traits of threading inserts, such as hand of insert, thread profile, and additional information.

Insert Overview
The document includes an overview of various threading insert styles, their applications, and the standards they adhere to, such as ANSI, ISO, and API. It covers a range of thread forms, including partial profile, metric ISO, American UN, UNJ, NPT, Whitworth, API, Acme, Stub Acme, and American Buttress.

Specifications and Product Details
The document provides detailed specifications for various Kennametal KM40TS™ threading tools, including both left-hand and right-hand models. Each tool is listed with its order number, catalog number, dimensions in millimeters and inches, and associated components such as insert screws, shims, and clamp assemblies.

Threading Solutions
The document highlights the Top Notch™ Thread Tooling system, designed for high productivity and superior performance in threading operations. It emphasizes the system's advantages, such as rigid insert clamping, excellent surface finish, and suitability for various materials and thread forms.

Grade Selection and Technical Information
A comprehensive grade selection chart is provided, detailing recommended grades and surface speeds for threading different workpiece materials.

Troubleshooting and Solutions
The document includes a failure and solution guide, addressing common threading problems such as chatter, built-up edge, deformation, chipping, and broken noses.

Machining Guidelines
General machining guidelines are provided, including recommendations for radial, flank, modified flank, and alternating flank infeed methods.

Chop Control Inserts
The document discusses the use of Kennametal's chop control inserts, which improve chip control and reduce heat generation, enhancing tool life and productivity.

Threading Infeed Passes
Recommendations for threading infeed passes are outlined, including formulas for determining the number and size of passes.

Conclusion
