Forster "HOT" Pilot The Hand Held Outside Neck Turner features the industry's only carbide neck thickness cutter - no sharpening required. Precision machined with special angles and reliefs designed specifically for neck turning; cutter approach angle allows turning right up to the case shoulder. Micrometer adjustment knob allows fine adjustments in either direction; easily adjustable to .0005". Index marks at increments of .001" are clearly stamped on the tool body. Dedicated Pilots are sold separately, .002" to .0025" smaller than the bullet diameter. Do not confuse with Pilots for the Case Trimmer Cutter Shaft or the Case Trimmer Outside Neck Turner, none of which is interchangeable.
