Stahlwille SW512SG-QRN 1/2" Drive QuickRelease Fine-Tooth Ratchet, 80 Teeth, 265.5 mm

The 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 265.5 mm long and weighs 654 g (manufacturer-stated).

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. Stahlwille lists it to DIN 3122 / ISO 3315 and gives the material as chrome alloy steel, chrome-plated, forged (manufacturer-stated).

The datasheet lists the 513 and 514 adaptors as accessories.

Key specifications

Selecting the right option

Choose the 512SG-QRN when you want the 4.5° swing of an 80-tooth ratchet in 1/2" drive. The Stahlwille 512-2K 1/2" Drive Reversible Ratchet is the 36-tooth ball-detent ratchet with a 2-component handle (600 g), the Stahlwille 517QR 1/2" Drive QuickRelease Flexible-Joint Ratchet adds a flexible joint and the Stahlwille 516 1/2" Drive Telescopic Reversible Ratchet is telescopic. The datasheet lists the Stahlwille 513 Reducing Adaptor and the Stahlwille 514 Step-Up Adaptor as accessories, and names spare parts kit 19042020, a different order number from the Stahlwille 5120QR Ratchet Spare Parts Kit in this range (19040020), so check the fit before ordering a kit.
