What is spindle taper?
A machine taper is a system for securing cutting tools or toolholders in the spindle of a machine tool or power tool. Almost all machine tool spindles, and many power tool spindles, have a taper as their primary method of attachment for tools.

How do I know if I have MT1 or MT2?
Almost all hobby and professional woodworking lathes will use either a MT1 or MT2 sized fitting. This is easily determined by measuring the inside diameter of the spindle. Dimensions may vary slightly according to the depth of the taper, but should be near to the size stated.
What is #2 Morse taper?
Q: When ordering new lathe spindle and tailstock parts, they are listed as #1 taper or #2 Morse taper. The difference between a #1 Morse taper and a #2 is basically the length and the “section” of the taper. Think of a long, tapered rod that starts at a point and gets larger in diameter the farther down the rod you go.
Why do tapers lock?
A taper machined onto two mating parts such that when the parts are mated the frictional forces are so great will not rotate or move with respect to one another. No clamping forces are required to keep the parts joined, but considerable force is required to separate the items.
Can you use a MT2 taper on a lathe?
Usually if your lathe is designed to use a MT1 taper it is because it is only structurally designed for smallerl work. Upping the shank to a MT2 may be dangerous and overload the capacity of your lathe.
What kind of tool is attached to a taper?
Almost all machine tool spindles, and many power tool spindles, have a taper as their primary method of attachment for tools. Even on many drill presses, handheld drills, and lathes, which have chucks (such as a drill chuck or collet chuck ), the chuck is attached by a taper.
What kind of taper does a twist drill take?
Drill chucks mounted by Jacobs tapers onto arbors with Morse tapers for the spindle. Spindle nose on a lathe headstock. The small female taper is a Morse taper to take a lathe center or a tool such as a twist drill. The large male taper takes a lathe chuck, which is retained by the large nut.
What does taper mean in a milling machine?
Virtually all milling machines, from the oldest manual machines up to the most modern CNC machines, utilize tooling that is piloted on a tapered surface. The machine taper is a simple, low-cost, highly repeatable, and versatile tool mounting system.
