Micro-Adjustable Neck Turner
The K&M neck turner has a very unique cutter adjustment mechanism that allows for a very precise cutter adjustment. This design incorporates very fine pitched threads of a screw within a screw concept which yields 0.002” cutter advance for each rotation of the adjustment nut. As a point of reference and comparison a micrometer advances the spindle 0.025” for every revolution of the thimble. There are etched markers on the neck turner body around the circumference of the cutter adjustment screw hole placed every 30 degrees radially and as a reference there is one punch mark on the face of the adjustment nut. When the adjustment nut is rotated one increment the cutter advancement is 0.0002”.
To properly combat the formation of a doughnut the neck should be turned so the cut ends very slightly into the shoulder. Our cutter lead angle will accommodate all shoulder angles by allowing you to cut into the neck/shoulder junction while the leading angle “blends out” of the shoulder.
You can drive the cartridge with the power adapter and proper shell holder by hand when the handle is installed or remove the handle from the power adapter and insert the ¼” hex stem into a cordless screw driver.
Start off by selecting your cutter material type with neck turner body; you can choose between steel and carbide. Secondly, you will select the pilot within the neck turner; here you have 3 options, steel, carbide and carbide cutting. Third, you need a case driver and case holder to turn the brass. We strongly recommend purchasing the power adapter handle for first time buyers. The last thing you need to have is our expand mandrel with press adapter. Everything else including the ergo holder, pilot jack, power grip, window riser, protective case and wax are accessories that aid in the useability of our neck turning tools. Please contact us if you are unsure.
THIS IS THE STEEL PILOT ONLY
