Stahlwille SW452QR 3/8" Drive QuickRelease Flexible-Joint Ratchet, 80 Teeth, 300 mm

The Stahlwille 452QR is a reversible 3/8" drive fine-tooth ratchet with a flexible joint, 80 teeth, a 4.5° working angle and a QuickRelease push button. It is 300 mm long, weighs 350 g and has a 2-component handle (manufacturer-stated).

The handle joint swivels about 90° and latches in four positions: straight, 30° up, 60° up and 30° down. The lock is released with a push button in the grip area. The QuickRelease system secures each component from the ratchet through the extension, and 8 tooth pairs engage in parallel. Stahlwille lists it to DIN 3122 / ISO 3315 and gives the material as chrome alloy steel, chrome-plated (manufacturer-stated).

The datasheet lists the 431 and 432 adaptors as accessories.

Key specifications

Selecting the right option

Choose the 452QR when access, not just swing, is the problem. For a straight 3/8" ratchet with the same tooth count see the Stahlwille 435QR N 3/8" Drive QuickRelease Fine-Tooth Ratchet or the Stahlwille 435SG-QRN 3/8" Drive QuickRelease Fine-Tooth Ratchet. The smaller and larger flexible-joint ratchets are the Stahlwille 416QR 1/4" Drive QuickRelease Flexible-Joint Ratchet (1/4" drive) and the Stahlwille 517QR 1/2" Drive QuickRelease Flexible-Joint Ratchet (1/2" drive). The datasheet lists the Stahlwille 431 Reducing Adaptor and the Stahlwille 432 Step-Up Adaptor as accessories.
