Ratchet insert tool SDRT series

Sturtevant Richmont offers different ratchets to meet the needs of different industries. In addition to the normal industrial assembly, tool ratchets we also offer "Hold and Drive" ratchets for aerospace. Scrolling down this page provides you with a good look at our ratchets. Even the world's best ratchets wear out, and at the bottom of the page, you will find the ratchet renewal kits. Fine Tooth RatchetThe Finethooth Ratchet is the latest in the Sturtevant Richmont ratchet family. From the first glance at this ratchet, you'll immediately notice the differences. The differences can be found in more than the looks. People love the durability they experience using our ratchets. But for every strength, there can be a trade-off. We found a way to eliminate the trade-off so you get the legendary durability from our Finetooth Ratchet and you get an improved swing arc. The number of teeth on the ratchet drive gear determines the swing arc needed for the ratchet to grab the next tooth and move the drive gear. If a drive gear has 20 teeth, the wrench must swing 18 degrees in order to grab the next tooth. With 40 teeth, the wrench must swing 9 degrees to grab the next tooth and move the drive gear. With our new Finetooth Ratchet, the swing arc is less than 5 degrees. Combine the smaller body with the shorter swing arc and you can use this ratchet in places that you couldn't use our other ratchets.
