ISO 603-16:2022

Overview

ISO 603-16:2022 - "Bonded abrasive products - Dimensions - Part 16: Cutting-off wheels on hand held power tools" specifies the most common nominal dimensions (in millimetres, with inch equivalents) for bonded abrasive cutting-off wheels intended for use on hand-held power tools (for example, angle grinders and straight grinders). The standard covers two shape types defined in ISO 525: shape type 41 (flat cutting-off wheel) and shape type 42 (depressed centre cutting-off wheel). It is the second edition (2022) and updates the 1999 version with clarified scope, added terms, adjusted figures and commonly used imperial sizes.

Key topics and requirements

• Scope: Defines the common nominal outside diameters, thicknesses and bore/internal dimensions for shape types 41 and 42 used on hand-held power tools.
• Shapes covered:
  • Type 41 - flat cutting-off wheel.
  • Type 42 - depressed centre cutting-off wheel (note: variations with threaded hub are possible).
• Dimension data: Tables list the most common nominal sizes (mm with inch equivalents) and typical bore diameters for global acceptance (examples include common diameters such as 76, 100, 125, 230, 300 mm etc.).
• Designation: Wheel designation shall follow ISO 525 (shape types, designation and marking).
• Exclusions: ISO 603-16 does not specify limit deviations or run‑out tolerances - those are given in ISO 13942.
• Units and presentation: Dimensions and tolerances expressed in millimetres; inch values shown in brackets.

Applications and users

ISO 603-16 is practical for:

• Manufacturers of bonded abrasive cutting-off wheels - to select and publish standard nominal dimensions.
• Tool and accessory suppliers and distributors - to ensure product listings match common dimensions and bores for angle/straight grinders.
• OEMs and machine users - for specifying compatible wheel sizes for hand‑held power tools and for procurement.
• Quality assurance and testing labs - as a reference for dimensional checks (paired with ISO 13942 for tolerances).
• Standards committees and technical purchasers who need harmonized dimensions for interchangeability and safety.
