Function and Application

A taper key releases tools with a Morse taper shank from the spindle, tailstock, or a reduction sleeve, without needing a drift key and a hammer blow. The lever mechanism engages the tang of the tool taper through the cross slot in the socket and pushes the taper out evenly. This protects the spindle bearing and quill, replacing the classic method of drift key and hammer.

MK 1-3 or MK 4-6: choosing the right size

GSR offers the semi-automatic taper key in two size ranges, matching the common tool tapers to DIN 228. The table below shows which size fits which machine.

Frequently Asked Questions

What is a Morse taper key?

A tool that releases Morse taper shanks to DIN 228 from the spindle, tailstock, or a reduction sleeve without a hammer blow. The lever mechanism engages the tang of the tool taper.

Which taper key size fits my machine?

MK 1-3 covers common smaller drilling and milling machines, MK 4-6 the larger drilling, milling, and lathe machines. You can find the taper type of your spindle in the machine data sheet or directly on the tool taper.

Can the taper key also separate nested tapers, e.g. a tool from a reduction sleeve?

Yes, both models also release two nested Morse tapers, for example a tool from a reduction sleeve, on the workbench.
