Returns Simplified.The Sherline 3.0mm (.1181) WW Collet offers a precise and efficient method for mounting cylindrical parts or bar stock in a lathe, ensuring high centering accuracy. This collet functions as a small, precision 3-jaw chuck that fits into a specially designed tapered adapter within the headstock. The mechanism involves a drawbar threading through the headstock and into the collet’s backside, drawing it into the adapter and causing the jaws to close and securely grip the part for machining.
WW collets are distinct from milling collets due to their through-hole design, allowing stock to pass entirely through up to a maximum diameter of 3/16″ or 4.5mm. The collet’s accuracy is notable, with a maximum runout of .002″ or less, provided the WW collet adapter is trued as per instructions. This ensures optimal performance and precision during use.
Sherline collets are logically numbered, with metric collets beginning with part number 1178, followed by digits indicating size in 0.1 mm increments. These collets are manufactured to standard WW specifications, with a shank diameter of .312-.313 and a .275-40 thread. It is important to verify compatibility with other manufacturers’ WW collets to ensure they fit the Sherline adapter. Metric sizes range from .3 mm to 8.0 mm, available in increments of .1 mm.
