2013-05-30· A Morse taper is defined by the angle that the taper surfaces make relative to the longitudinal axis of the component and by the mismatch angle between the male and part. The original Morse taper angle defined by Stephen Morse for tools was a relatively small angle of 2° 50′, with the mathematical relation that tang 2° 50 = 5 %.
NOTE: At times, the Morse Taper cavity in a machine may be slightly smaller than the maximum diameters shown above. This is because the MT tooling often extends a bit past the end of the spindle that is receiving the Morse Taper Tool.
Morse Tapers¶ Different numbers of Morse Tapers have slightly different tapers, but all approximate 5/8 inch per foot (0.05208 inch per inch). Morse taper shanks are used on a variety of tools, and exclusively on the shanks of twist drills.
Morse Taper Drill Bit Shank. The Morse taper twist drill bits pictured right are used in metalworking. The full range of tapers is from 0 to 7. The Morse taper allows the bit to be mounted directly into the spindle of a drill, lathe tailstock, or (with the use of adapters) into the spindle of milling machines. It is a self-locking (or self holding) taper of approximately 5/8" per foot that ...

The taper fits into the spindle allowing the machine spindle to transfer rotary motion to the tool holder which holds the tool. A toolholder has a 2 part specification, taper and tool. This page covers the machine-to-toolholder standard and not the holder-to-tool standard. and example might help.
2018-11-27· The legs of the table had a slight taper to them. 2005, Michael Ellis, Apollo Rises (page 15) Her hair hangs over her ears and flows to a taper at the back of her neck where it is held in place with a wide and circular black clasp.
Machine taper's wiki: A machine taper is a system for securing cutting tools or toolholders in the spindle of a machine tool or power tool. A male member of conical form (that is, with a taper) fits into the socket, which has a matching taper of ...
Jacobs taper 2 1/2. I changed the description of JT 2 1/2 from "obsolete" to "obscure". I just spent a few hours looking for info on it, and it seems that, as far as anyone can tell, it's only used on cheap Taiwanese drills from the 1970s and 80s, with no spares available.
Morse Taper 4 1/2 Just to add more confusion, there's also the Morse "four and a half" taper. My understanding is that this was inserted later as a size small enough to fit inside a standard 2 1/4 inch threaded spindle head, but large enough to accommodate 5C collets.
Morse tapers, for example, taper at anywhere from 0.04988 inches of diameter per inch of length (for the Morse 1) to 0.05262 inches of diameter per inch of length (for the Morse 5). Details of use Bits or accessories are inserted into a tapered receptacle and pushed or twisted into place.
The shank is the end of a drill bit grasped by the chuck of a drill. The cutting edges of the drill bit contact the workpiece, and are connected via the shaft with the shank, which fits into the chuck.
