ISO 2336-2:2006

Overview

ISO 2336-2:2006 specifies the dimensional requirements for machine hacksaw blades. The standard applies to single-edge blades with lengths from 300 mm to 700 mm and a maximum tooth pitch of 8.5 mm. Dimensions and tolerances are given in millimetres, and unspecified tolerances follow ISO 2768-1 (tolerance class "m"). The document supports consistent manufacture and reliable interchangeability of machine hacksaw blades.

Key Topics

• Scope: Applicable to single-edge machine hacksaw blades, length 300–700 mm, tooth pitch ≤ 8.5 mm.
• Dimensions: Blade length (l) is defined as the distance between centres of pin holes (diameter d). The centre of the pin hole is recommended to lie on the blade centreline.
• Tooth specification: Tooth pitch P and the number of teeth N are specified per 25 mm.
• Tolerances: All dimensions and tolerances are metric; tolerances not explicitly given are to be taken from ISO 2768-1, class "m".
• Designation format: Machine hacksaw blades are designated by type and dimensions, for example:
  • Saw blade ISO 2336-2 - 300 × 25 × 1,25 × 10 (l × a × b × N, where l = length, a = width, b = thickness, N = number of teeth in 25 mm)

Applications

ISO 2336-2:2006 is primarily used by manufacturers, quality engineers and procurement professionals involved with metal-cutting saws and cutting tool production. Practical applications include:

• Ensuring manufacturing consistency when producing machine hacksaw blades to standard dimensions.
• Enabling interchangeability between blades from different suppliers for machine tools that use pinned or mounted blades.
• Supporting quality control by providing clear dimensional definitions and tolerance references.
• Facilitating clear product designation for stock management, procurement and compliance documentation.

The standard helps reduce mismatches in blade fitting and improves safety by standardizing hole positions and dimensional references used in machine mounting.

Related Standards

• ISO 2336-1 - Dimensions for hand hacksaw blades (companion document covering hand blades).
• ISO 2768-1 - General tolerances - Part 1: Tolerances for linear and angular dimensions without individual tolerance indications (normative reference for unspecified tolerances).

For manufacturers and users of machine hacksaw blades, ISO 2336-2:2006 provides the essential dimensional framework required to produce, verify and specify blades that are safe, compatible and consistent across suppliers.
