What is BS EN 847‑2 – Safety of milling tools about?
BS EN 847‑2 is the second part of the EN 847 multi-series that discusses safety requirements for woodworking tools.
BS EN 847‑2 specifies the determination of the maximum speed for given eccentricity at clamping devices for the shank strength of milling tools with cylindrical and taper shank. BS EN 847‑2 also specifies the marking of the tool. Bore mounted tools e.g., milling tools, circular saw blades which are mounted on an arbour should be considered as a shank-mounted tool.
BS EN 847‑2 complements BS EN 847-1 and applies also for shank tools with a cutting diameter of less than 16 mm.
Note: BS EN 847‑2 is not applicable for shanks of tools according to this scope, which are manufactured before the date of its publication.
Who is BS EN 847‑2 – Safety of milling tools for?
BS EN 847‑2 on safety requirements for the shank of shank-mounted milling tools is useful for:
- Manufacturers of woodworking tools
- Designers of woodworking tools
- Suppliers and importers of woodworking tools
Why should you use BS EN 847‑2 – Safety of milling tools?
Cylindrical shank on milling machines is an important component of the machine as it functions as the holder for the endmill. If the shank fails due to some reason, then it could compromise the milling tool’s integrity and thereby increase the possibility of hazards.
BS EN 847‑2 identifies the potential hazards and the conditions that can cause them. BS EN 847‑2 provides you guidance to eliminate the possibility of these hazards.
Overall, the guidelines of BS EN 847‑2 enable you to design shank-mounted milling tools that meet the minimum safety requirements and thereby ensure the operators safety.
