Sherline Mill Collet Set 3060
Mill Collet Set
Sherline milling collets are designed to be used with the Morse #1 internal spindle taper that is standard on both the Sherline lathe and vertical mill. Because of the shallow angle of the Morse #1 taper when the drawbolt is tightened, greater clamping force can be applied when compared to the clamping pressure of WW collets. Therefore, we recommend the use of these milling collets for holding miniature size end mills (3/16″ or 1/4″ shank), #1 and smaller center drills or Dremel bits (1/8″ shank), and assorted other cutters.
The Sherline milling collet set P/N 3060 consists of several sizes. These include 1/8″, 3/16″ and 1/4″ mill collets, a drawbolt and a thrust washer. (The metric set P/N 3090 includes 3 mm, 4 mm and 6 mm sizes.)
Other size collets in inch and metric sizes are also available:
Cutting tools held by these collets must have a shank size within .001″ of the manufactured size. Because of the shallow taper angle, these collets will not loosen from the spindle. You will need to back the drawbolt off a couple of revolutions and tapping the drawbolt to free the collet.
