Returns Simplified.The Sherline 3.7mm (.1457) 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 into the collet’s backside, drawing it into the adapter, which in turn closes the jaws to grip the part securely.
WW collets are distinct from milling collets due to their through-hole design, allowing stock with a maximum diameter of 3/16″ or 4.5mm to pass entirely through. Collets larger than this diameter are known as “pot” chucks and are not bored through, offering a depth of .260″. The collet’s accuracy is notable, with a maximum runout of .002″ or less, provided the WW collet adapter is trued as per instructions.
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 not hardened but are manufactured to standard WW specifications. It is crucial to verify compatibility with Sherline’s adapter when considering WW collets from other manufacturers. Sherline also offers a slightly larger adapter and drawbar set to accommodate some other brands of 8 mm collets.
