Document Overview

The document appears to be a comprehensive technical catalog or manual related to toolholders, inserts, and cutting tools, featuring product indexes, identification systems, and specifications. It includes bilingual content (English and Chinese) and covers various product codes, dimensions, and standards.

1. Product Indexes

Multiple sections labeled from A01 to A44 provide indexes by product, listing page references for different product categories. These indexes serve as navigation aids to locate specific tools or components within the catalog.

2. Toolholder and Insert Identification Systems

The document details identification systems for boring bars and tool holders, including:

• Cross Section Numbering: For square shanks, the number represents sixteenths of width and height; for rectangular holders, the first digit indicates eighths of width and the second digit quarters of height. A special case is the 1-1/4 x 1-1/2 holder, designated as number 91.
• Shank Types: Codes such as S (steel shank), A (steel shank with coolant hole), C (cemented carbide shank with steel head), and E (cemented carbide shank with steel head plus coolant hole) define shank construction.
• Dimensions: Shank diameter, height, width, and toolholder length are specified in both ISO (mm) and ANSI (inch) units.
• Bar Diameter: Indicated by a two-digit number in 1/16-inch increments or in millimeters.

3. Insert Specifications

Insert characteristics are described with the following parameters:

• Insert Size (I.C.): Insert size is given, often in fractions or decimals, representing the inscribed circle diameter.
• Cutting Edge Angle and Insert Clearance Angle: These angles define the geometry of the cutting edge and clearance for effective machining.
• Insert Shape: Various shapes are coded with letters (A, B, C, D, E, F, K, L, M, O, R, S, T, V, W).
• Insert Tolerances: Tolerance classes are specified according to ISO and ANSI standards.
• Chip Breaker Design and Insert Features: Codes such as L, R, B, E, V, O, T, A, D, K, S, F, W, C, M indicate chip breaker types and other insert features.
• Corner Radius (R): Corner radius values are provided in both millimeters and inches, with symbols indicating edge shape (rounded, sharp, chamfered, chamfered and rounded).
• Insert Thickness: Thickness is measured from the base to the highest cutting edge point.

4. Toolholder and Insert Locking Types

The document references types of locking mechanisms for inserts, though specific types are not detailed in the excerpt.

5. Standards and Units

Both ISO (metric) and ANSI (inch) standards are used throughout the document for dimensions, tolerances, and identification codes, ensuring compatibility with international machining practices.

6. Additional Notes

• Special codes and optional codes are used to denote unique features or specifications.
• The document includes bilingual labels for clarity in both English and Chinese.
• Repeated sections suggest mirrored or duplicated content for different catalog versions or languages.

Summary

This technical document serves as a detailed reference for toolholders and inserts, providing standardized identification systems, dimensional specifications, and product indexing. It is essential for users selecting or specifying cutting tools and holders, ensuring precise communication of tool geometry, size, and compatibility.
