Stahlwille QuickRelease 1/2" ratchet

Stahlwille 512SG-QRN is a reversible 1/2" drive fine-tooth ratchet with 80 teeth, a 4.5° working angle, a QuickRelease push button and a solid steel handle. It is 265.5mm long and weighs 654 g.

The solid handle is forged steel, so there is no detachable grip material, and the switch lever is recessed for easy direction changes. The design is screwless, 8 tooth pairs engage in parallel, and the QuickRelease safety lock stops inserted tools coming loose; they are released at the push of a button. It is made to DIN 3122 / ISO 3315 from chrome alloy steel, chrome-plated, forged. The 513 and 514 adaptors are available as accessories.
