ER32 18pc metric collet set and chuck - 2 morse taper

Collets deliver an extremely accurate workpiece and tool holding solution, and in a morse taper collet chuck they can be used at either end of the lathe. They compress to form a perfect circle at a given diameter over the full length of the collet, and although more expensive than a drill chuck, a set of collets will provide far more versatility and precision. They are much more gentle on the workpiece too.

Denoted by an ER number, collets are made in various standard sizes, which fit in a collet chuck that has the same number.  The ER number defines the length and outside diameter of the collet, and within each ER size, the range of inside diameters available is also defined. In other words, the ER size dictates the minimum and maximum diameter of the workpiece or tool that you will be able to hold.

ER32 collets are the ideal size for kitless pens and custom pen making, as the range of collet diameters available within that size is perfect for the various processes involved in pen making, and they grip over a length of 40mm, which is neither too short or too long.

Our precision engineered ER32 metric collet set has all the collets you'll probably ever need for kitless pens and custom pen making.

The set comprises 18 collets from 3mm to 20mm, a morse taper collet chuck with either a 1MT or a 2MT arbor, and a wrench to assist with tightening the chuck. It is supplied in an aluminium case for storage or carrying, with high density foam padding which has separate cut-outs for each component.

The morse taper arbor is threaded to enable it to accept a draw bar, the 1MT with an M6 thread and the 2MT with an M10 thread.
