ISO 10145-1:2016

Overview

ISO 10145-1:2016 defines the standardized general dimensions for end mills with brazed helical hardmetal tips featuring a parallel shank. This international standard applies to two main types of end mills with parallel shanks:

• End mills with plain (smooth) parallel shank
• End mills with flatted (flattened) parallel shank

The standard is applicable to both right-hand and left-hand cutting end mills, regardless of their helix angle or number of flutes. It provides manufacturers, suppliers, and users with a clear framework to ensure dimensional compatibility, interchangeability, and quality when specifying or producing end mills with brazed tips and parallel shanks.

Key Topics

• General Dimensions: ISO 10145-1:2016 specifies the precise measurements such as cutting diameter, shank diameter, length of cut, and overall tool length for end mills with both plain and flatted parallel shanks.
• Tool Types Covered:
  • Plain parallel shank end mills (smooth cylindrical shank)
  • Flatted parallel shank end mills (shank includes a flat surface for secure mounting)
• Handing and Variability: Applies to both right-hand and left-hand end mills, independent of helix angle and number of flutes, making it widely applicable across various cutting tool designs.
• Normative References: The standard references ISO 3338-1 and ISO 3338-2 for dimensional characteristics of plain and flatted parallel shanks, respectively.
• ISO 13399 Compatibility: Annex A of the standard provides the relationship between designations used in ISO 10145-1 and the preferred symbols standardized in ISO 13399, facilitating digital tool data management and global tool catalog integration.

Applications

• Manufacturing and Machining: Ensures compatibility of end mills manufactured with brazed hardmetal tips for milling operations, improving efficiency and interchangeability in industries such as automotive, aerospace, and general metalworking.
• Tool Design and Specification: Assists tool designers and engineers in selecting or creating end mills that meet global dimensional norms, ensuring tools fit properly in machine tool holders with parallel shanks.
• Quality Assurance: Enables standard-compliant quality control by providing exact dimension parameters, reducing errors, rejections, and downtime caused by non-standard tooling sizes.
• Supply Chain Coordination: Helps tooling suppliers and distributors maintain uniform product lines and clear specifications to meet customer expectations internationally.
• Digital Tool Management: Facilitates integration of end mill data in CAD/CAM systems and tool databases through references to ISO 13399 terminology and symbols.

Related Standards

• ISO 3338-1: Specifies dimensions of plain parallel shanks for milling cutters, referenced in ISO 10145-1 for plain shank dimensions.
• ISO 3338-2: Covers dimensional characteristics of flatted parallel cylindrical shanks for milling cutters, also normatively referenced by ISO 10145-1.
• ISO 13399 Series: International standard for the representation and exchange of cutting tool data. ISO 10145-1 links its designations to ISO 13399 symbols to promote digital consistency.
• ISO 10145-2: Complements this standard by specifying dimensions of end mills with brazed helical hardmetal tips but featuring 7/24 taper shanks instead of parallel shanks.

Adherence to ISO 10145-1:2016 enables users across the tooling and machining industries to achieve uniformity, reduce ambiguity in dimensions, and optimize tool performance. The focus on parallel shank end mills with brazed hardmetal tips addresses a critical area in cutting tool manufacturing and application, supporting efficient production and global trade compliance.
