13mm Capacity Drill Chuck - MT1

Complete with Chuck key and threaded morse taper shaft

Morse  Taper  1   ( MT1 / MK1 )

These drill chucks are good quality at a very reasonable price. They are ideal for light and medium duty work, on both metal or woodturning lathes, equally suitable for a pillar drill with morse taper fitting.  We also have this chuck in a MT2 fitting listed in our Ebay shop.

One of the things that confuse many people is the Morse taper; how it works or simply what size Morse taper they need for their own lathe. I have written below a few brief notes to try and help, but If you have any questions then please ask.

What is a Morse taper? 

The Morse Taper is the "  hollow tapered hole" found in the centre of the Headstock and in the Tailstock of Lathes (as well as some Pillar drills and Milling machines) made to common diameter sizes with a universally recognised tapered profile. Morse Tapers come in eight sizes. The taper size is normally identified by a single digit ranging from 0 to 7  (0 being the smallest) which is normally just abbreviated to the letters "MT", so a MT2 is a Morse Taper Number 2.  It is fairly easy to identify which MT you need by simply measuring the hole diameter in your tail stock. The approx Morse Taper hole sizes are listed below. The morse taper fitting is attached to the chuck by a thread.

MT1 = 12mm    MT2 = 18mm   MT3 = 24mm  (MT1 & MT2 being the most popular).

How does a Morse Taper work? 

Lathes, by their nature, operate in a rotary manner and normally a rotating workpiece comes into contact with a fixed tool, i.e. a drill bit held in a drill chuck held in the tailstock. The chuck must be held firmly in place, properly centred in line with the axis of rotation, but also able to be quickly and simply removed. The best way of achieving this was found to be using a tapered metal bar (similar to a ice cream cone with the top cut off) fitted into a hollowed tapered hole (or sleeve) in the head or tail stock. The large tapered surface area of the cone holds the shaft very securely in place through friction; hence the invention of the Morse Taper was born (invented 1864 by A. Morse). The Morse Taper is now  universally accepted as the standard Machine Taper used throughout the world.
