The Jacobs Taper (abbreviated JT) is commonly used to secure drill press chucks to an arbor. The taper angles are not consistent varying from 1.41° per side for No. 0 (and the obscure # 2 + 1 ⁄ 2) to 2.33° per side for No. 2 (and No. 2 short). There are also several sizes between No. 2 and No. 3: No. 2 short, No. 6 and No. 33.
A taper pin is a fastener used in mechanical engineering. They are steel rods with one end having a slightly larger diameter than the other. Metric taper pins have a taper of 1:50. [1] A 1:50 taper means that one end of a 50 mm long bar will be 1 mm smaller in diameter than the other end.
For example, the self-releasing NMTB/Cat taper is 3.5/12, which is only 16.5943° cone angle (8.2971°per side) (pictures available by typing "NMTB taper" into images.google.com). If one of the questions is "how did Morse know what degree of taper would produce self-holding rather than self-releasing", the answer is undoubtedly simple "cut and ...

Negative rake: A tool has a negative rake angle when the face of the cutting tool slopes away from the cutting edge at outer side. Positive rake angles generally: Make the tool more sharp and pointed. This reduces the strength of the tool, as the small included angle in the tip may cause it to chip away. Reduce cutting forces and power ...

A taper pin is a self tightening device due to the shallow angle of the taper. They may be driven into the tapered hole such that removal can only be done with a hammer and punch. They are sized by a number sequence (for example, a No.4 reamer would use No.4 taper pins).
Moore shot to stardom with steamy roles in Ghost and Indecent Proposal, and famously posed naked at seven months pregnant on the August 1991 cover of Vanity Fair.
