The DEWALT DWMT81155 3/8-Inch Drive Flex-Head Ratchet is built for mechanics and DIYers who need to work around obstructions. The 180-degree flexible head and 5-degree arc swing let you reach fasteners that a standard ratchet can’t, and the 72-tooth gear gives you a high-torque, small-swing action.

180° flexible head pivots for access around obstacles
5° arc swing and slim head design for restricted areas
72-tooth gear system produces high torque

Maintaining and Repairing Your DWMT81155

Product Details
More Access, More Torque
The flex head pivots to clear obstacles while the 72-tooth gear gives you enough swing to turn fasteners even where movement is limited.
Rebuild and Repair Basics
Internal gears and pawls can wear after heavy use. Look for a DWMT81155 rebuild kit to replace worn parts; the flex head joint can also be adjusted or rebuilt with the right components.
Why 5° Swing?
Standard ratchets often require 6–10° of movement. The DWMT81155’s 5° swing lets you make progress on bolts that only allow a few degrees of rotation.

Perfect for tight spaces
The flex head is perfect for tight spaces. The 72-tooth gear means you don't need much swing. Solid tool.

Top-notch ratchet
I've been a mechanic for decades and this ratchet is top-notch. The 180-degree head lets me get into spots that are impossible with a standard ratchet. The teeth are fine so it works even in cramped engine bays. The grip is comfortable and doesn't get slippery with oil. It's built like other DEWALT tools—tough. I've already used it on several jobs and it hasn't skipped a beat. Definitely recommend it.

Saved my knuckles
I'm not a pro, just a weekend wrench on my truck. This ratchet made replacing the starter so much easier. The flex head saved my knuckles. The handle is grippy and the ratchet mechanism is solid. It's a good buy for anyone who works on cars.
