• Sherline 2.5mm (.0984) WW Collet
• Ensures high centering accuracy
• Offers precise 3-jaw chuck function
• Accommodates 3/16" or 4.5mm stock
• Notable runout of .002" or less
• Follows standard WW specifications

The Sherline 2.5mm (.0984) 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 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 referred to as "pot" chucks and are not bored through, being only .260" deep. 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 two digits indicating the 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, though they are not hardened. It is crucial to verify compatibility with other manufacturers' WW collets to ensure they fit the Sherline adapter.
