Overview
ISO 3292:2016 specifies the dimensional requirements and designation rules for extra-long parallel shank twist drills. The standard covers drills with diameters from 2 mm to 14 mm and overall lengths in the range 125 mm to 400 mm. It provides a consistent basis for specifying, manufacturing and procuring extra-long parallel shank twist drills used in industrial drilling and tooling operations.
The document is a third edition (2016) and references ISO 10899 for technical specifications. Annex A maps designations from ISO 3292 to the ISO 13399 cutting-tool data model to support data exchange and tool management systems.
Key Topics
- Scope and size range: Drill diameters from 2 mm up to 14 mm and overall lengths 125–400 mm.
- Preferred overall lengths: Typical preferred overall lengths included in the standard are 125, 160, 200, 250, 315, and 400 mm to simplify selection and stocking.
- Technical compliance: Unless otherwise specified, technical requirements follow ISO 10899 (high-speed steel two-flute twist drills).
- Designation rules: Clear naming convention to identify extra-long parallel shank drills by reference, diameter and overall length.
- Example designation: Twist drill ISO 3292 - 10 - 250 (d = 10 mm, l = 250 mm).
- Data mapping: Annex A provides the relationship between ISO 3292 property names and ISO 13399 symbols to aid digital tool-data systems.
Applications
ISO 3292 is primarily intended for manufacturing, tooling and procurement teams that require:
- Interchangeable drill specifications across suppliers and production sites.
- Streamlined procurement and inventory using a set of preferred sizes and standard designations.
- Tooling data integration with CAM, tool management and PLM systems via ISO 13399 mappings.
- Consistent technical compliance when specifying extra-long parallel shank drills for fixtures, deep-hole pilot operations and specialized machining tasks that require extended reach.
Benefits include reduced ambiguity in purchase orders, improved compatibility between machine-tool setups and easier lifecycle management of cutting tools.
Related Standards
