What it is
The Fervi 4/20D40 Weldon-type end mill holder is a tool holder for clamping shank end mills with a Weldon flat, fitted with a Ø 20 mm bore and ISO 40 mount. The construction respects the d1 - h6 tolerances, for an accurate fit with the tool. Made with certified Italian manufacture, it complies with Machinery Directive 2006/42/EC and carries CE marking.
These are chucks with a tapered shank, often Morse taper, that hold milling cutters or drill bits and fit into the taper of the machine tool.
What it is for
Used for milling faces, shoulders and slots on machine tools and in workshop machining of steel, aluminium and alloy parts.
How to use it
Clean the taper and the socket thoroughly of oil and swarf, then insert the shank with a slight twist and a firm push so that the taper seats. Tighten the tool with the specified key or drawbar. To remove it, use the proper tool, without striking the chuck.
