Extremely easy to operate, even for amateurs: Press the button, insert (clean, trimmed) cable until it stops, release the button and rotate the tool approx. 5-10x around the cable, remove the cable and remove the remainder of the insulation. You will be left with an exposed inner conductor 6.5 mm long and a braid freed from the sheath that is also 6.5 mm long. Handy and convenient insulation stripper and key for F-connector (HEX 11) in one tool. Supported cable types: RG59, RG6. 2 blades for stripping the outer conductor and the inner conductor simultaneously in one step. Both blades are permanently installed; the blade distance is 6.5 mm – ideal for crimp and compression plugs.
