Olsa Tools Swivel Head Ratchet 1/2-Inch Drive, 90-Tooth, Part 1248

Brand: Olsa Tools

Availability set by the retailer

The Olsa Tools Swivel Head Ratchet 1/2-Inch Drive, 90-Tooth (Part 1248) is a roto-style socket wrench with a round head and swiveling handle built for mechanics who need access in hard-to-reach spaces. The swivel ratchet head rotates a total of 270 degrees to accommodate a wider range of angles than standard ratchets, making it ideal for working in tight spaces at any angle. Raising the handle at a 90-degree angle lets you spin the ratchet easily and firmly, so getting sockets out of tight spaces is effortless. The precision-machined 90-tooth gear-to-gear mechanism requires only a 4-degree swing arc for work in small places, and the ratchets exceed ASME specification B107.10 by 150% — the 1/2-inch drive handles 563 ft-lb of torque. An innovative fork split in the ratchet allows slight flexing under high torque applications so it handles high stress without breaking. Carefully engineered with industrial-grade Chrome Vanadium (Cr-V) steel and a smooth, consistent corrosion-resistant finish for years of heavy-duty jobs. All Olsa Tools hand tools carry a limited lifetime warranty.

Choosing Ratchets & Wrenches

How do I pick the right ratchet drive size?

Choose the drive size by the fastener size and torque you need — 1/4-inch for small fasteners and tight spaces, 3/8-inch for general automotive and mechanical work, and 1/2-inch for high-torque lug nuts and large bolts. A higher tooth count means a smaller swing arc, which is useful in confined areas.

When do I need a flex-head or swivel ratchet?

When fasteners sit at an angle or in recessed areas where a fixed-head ratchet cannot align. A flex or swivel head lets you keep the handle clear of obstructions while the socket stays on the fastener, improving access in tight engine bays and assemblies.
