Full title and description

ISO 3286:2016 — Single point cutting tools — Corner radii. This International Standard specifies the preferred values for corner radii of single‑point cutting tools and applies to tools with or without removable inserts whose cutting corner is rounded.

Abstract

ISO 3286:2016 lays down the values for the corner radius of single point cutting tools and gives a small set of preferred radii to be used when manufacturing or specifying single‑point tools. It is applicable to all types of single‑point cutting tools (with or without inserts) where the tool corner is rounded, and replaces the earlier 1976 edition.

• Publication date: March 2016 (Edition 2, 2016).
• Publisher: International Organization for Standardization (ISO).
• ICS / categories: 25.100.01 — Cutting tools in general.
• Edition / version: Edition 2 (2016).
• Number of pages: 3 (ISO published document length).

Scope

The standard establishes preferred corner‑radius values for single‑point cutting tools and applies to any single‑point tool whose cutting corner is rounded, whether the cutting edge is integral or an insert. It is intended to harmonize design and specification practices for corner radii so that tool makers, users and purchasers share a common set of reference values.

Key topics and requirements

• Definition of applicable tool types — single‑point cutting tools including those with removable inserts.
• Preferred values for corner radii (a limited set of standardized radii to be used in specifications and manufacturing).
• Guidance for selecting corner radii appropriate to tool use and geometry (finishing vs roughing, material considerations — implied best practice rather than prescriptive cutting parameters).
• Relationship to the previous edition (supersedes ISO 3286:1976) and harmonization with national adoptions (e.g., BS ISO 3286:2016).

Typical use and users

Used by tool designers and manufacturers, tooling purchasers and procurement specialists, CNC/machining engineers, quality and inspection teams, and standards committees. Typical applications include specifying tool blanks and finished cutting tools for turning, facing, parting and similar single‑point machining operations where corner geometry affects surface finish, strength of edge and tool life.

Related standards

Related documents include the earlier ISO 3286:1976 (withdrawn and superseded by the 2016 edition) and other ISO standards and national adoptions dealing with cutting tool terminology, dimensions and testing published by ISO/TC 29/SC 9 and by national bodies (for example identical national adoptions such as BS ISO 3286:2016).

FAQ

Q: What is this standard?

A: ISO 3286:2016 is an International Standard that specifies preferred corner‑radius values for single‑point cutting tools (tools with a single active cutting point).

Q: What does it cover?

A: It lays down the preferred numerical values for rounded corner radii of single‑point cutting tools and indicates the applicability to tools with or without inserts; it does not prescribe cutting conditions.

Q: Who typically uses it?

A: Tool manufacturers, tooling purchasers, design and production engineers, inspection staff and standards bodies involved with cutting‑tool specification and interchangeability.

Q: Is it current or superseded?

A: The 2016 edition (Edition 2) is the current published version; it replaced the 1976 edition and was confirmed on review in 2021, so it remains current.

Q: Is it part of a series?

A: It is a stand‑alone International Standard produced under ISO/TC 29/SC 9 (cutting tools committee). It relates to the family of ISO standards addressing cutting tools, their dimensions, terminology and test methods.

Q: What are the key keywords?

A: single‑point cutting tools, corner radii, tool geometry, turning, inserts, ISO 3286.
