Overview
EN ISO 7787-1:2016 - Dentistry - Laboratory cutters - Part 1: Steel laboratory cutters (ISO 7787-1:2016) defines the dimensional and basic performance requirements for the nine most commonly used steel laboratory cutters used in dental laboratories. The standard ensures interchangeability and consistent quality for cutters used on dental materials (and also used in podiatry). It does not cover special blade geometries such as spiral blades or cross-cut teeth.
Key topics and technical requirements
- Material: Shaft and working part shall be made of steel; specific steel grade and heat treatment are at the manufacturer’s discretion.
- Shapes covered: Nine head shapes - Round (spherical), Cylindrical double-domed, Egg, Oval (transverse), Bud (rounded), Bud, Pear, Bud (slender), and Wheel.
- Nominal sizes and head dimensions: Specifies nominal diameters (commonly 040–080 for most shapes; wheel sizes up to 160), head lengths and the required number of blades for each nominal size. All dimensions are given in millimetres and measured per ISO 8325.
- Shank specification: Shank shall be Type 2 per ISO 1797 with a shank length of (38 ± 1) mm.
- Run-out tolerance: Total indicated run-out must not exceed 0.12 mm, measured according to ISO 8325.
- Sampling and acceptance: Validation sampling requires randomly selecting 10 instruments; product acceptance criteria are defined (failure if ≤8 pass; if 9 pass then test 10 additional samples and all must pass).
- Marking and designation: The standard includes rules for designation code numbers and marking to support traceability and correct selection.
Applications and who uses this standard
- Dental laboratories producing, finishing or trimming prosthetic restorations and appliances.
- Manufacturers of steel laboratory cutters and dental rotary instruments to design and mark compliant products.
- Quality managers and procurement specialists specifying cutters for laboratory workflows.
- Regulatory and conformity assessment professionals verifying dimensional and performance compliance.
- Podiatry tool suppliers and users, since these cutters are also used in podiatric procedures.
Practical benefits
- Ensures interchangeability across manufacturers and regions.
- Reduces risk of mismatched tooling and poor fit in handpieces/holders.
- Simplifies procurement by standardizing nominal sizes, shank type and marking conventions.
- Provides objective test and sampling criteria for QA and supplier validation.
Related standards
- ISO 1797 (Shanks for rotary instruments)
- ISO 8325 (Test methods for rotary instruments)
- ISO 2157, ISO 6360-3, ISO 1942 (designation, coding and vocabulary)
- Other parts of ISO 7787: Part 2 (Carbide cutters), Part 3 (Tungsten carbide for milling machines), Part 4 (Miniature carbide cutters)
Keywords: EN ISO 7787-1:2016, ISO 7787-1, steel laboratory cutters, dental laboratory cutters, dentistry standard, run-out tolerance, shank Type 2.
