Morse taper

Morse taper is the term for a form of interface, with the aid of which tools or toolholders can be anti-twist connected with the drive shaft of the wood processing machine. It consists of a relatively long cone (longer than a steep-angle taper per ISO standard) with steep rising angle (steeper than a steep-angle taper per ISO standard), which locks at its thicker end into a cylindrical toolholder with a union nut, or with the tool itself. It is equipped with a fine thread and union nut between the taper and toolholder. The morse taper holder in a high steep-angle taper acts as the counterpiece to the taper with the tool and a wide thread for the union nut. The taper is inserted in this with the tool, and it is secured against slipping out by tightening the union nut.

The name "Morse" originates from the name of the company, which set the foundations in place for this interface back in the 19th century.


Morse taper interfaces are available in various sizes, depending on the application area.

MK2 is used in wood processing in particular with tools for CNC-machining centres and in routers and boring machines (see technical term morse taper MK2)
MK5 is used in wood processing in particular with replaceable router heads on spindle moulders (see technical term spindle exchangeable)
