Sherline 1/4 in-3/8 in 2-position Rocker Tool Post 7603 Sherline 1/4 in-3/8 in 2-position Rocker Tool Post 7603 The P/N 40180 Sherline 1/4 tool post comes standard with 4000-series lathes and is intended to hold 1/4 HSS or brazed tip carbide cutting tools that are ground to the proper height. A rocker tool post P/N 3057 comes standard or 4400-series lathes. The rocker allows the height of the tool tip to be adjusted to accommodate tools that may have been ground a little above or below the part centerline. A 3/8 holder P/N 7600 will accommodate 3/8 round or square shank cutting tools. Now Sherline offers an optional 2-positon tool post that will hold both 1/4 and 3/8 square shank tools and also has the rocker feature on each side to allow for adjustment of the tool tip height. The 3/8 side is designed to fit the larger 3/8 square tool holders commonly used for carbide or diamond inserted tips. It will also hold Sherlines own P/N 2256 (RH) and 2257 (LH) 35° inserted tip and other 3/8 tool holders. It is machined from solid aluminum and has a black anodized finish. Purchase of this tool post will allow you to keep both your standard 1/4 high-speed steel tools set up for jobs where they are sufficient and also have a 3/8 carbide insert tool ready for jobs where it is required. Simply loosen and rotate the tool post 180° and your new tool is in position. NOTE: Carbide inserts and inserted tip tools are available through Sherline. See our page on carbide tools.
