Sherline 6.0mm Milling Collet 3094
6.0mm Milling Collet Milling Accessory
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.
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 without backing the drawbolt off a couple of revolutions and tapping the drawbolt to free the collet.
6.0mm Milling Collet and Other Sizes
The milling collets (P/N 3060) used with the Sherline vertical mill or vertical milling column are designed to be used with the Morse #1 taper common to all headstock spindles manufactured by Sherline.
The collets are held into the spindle with a drawbolt. The set includes 3 collets and a drawbolt with collar.
These collets have a shallow angle that gives them high clamping pressure. As a result, it makes them ideal for holding cutters. The shallow angle makes the collet “stick” after the collet drawbolt is loosened.
Back the bolt off a few turns (do not disengage completely) and lightly tap the head of the bolt with a hammer or mallet until the collet can be easily removed.
End Mill Holders
Because the hole through the spindle is only a little over 3/8″ (10mm), a collet that would accept a 3/8″ shank end mill is impossible to make. End mills with 3/8″ shank are very common and in many cases cost less than the miniature series.
They are available in many sizes and shapes. Consequently, Sherline offers the 3/8″ end mill holder (P/N 3079).
