For mechanics and technicians who need to turn a 3/8" socket where a normal ratchet handle has no room to swing. The TONE RH3HSS3 is a palm-size stubby ratchet: 75 mm long and 135 g, with a quick-spin dial built into the head and a drive square in the end of the handle (TONE).
Problems it solves
- No room to swing a handle. TONE describes it as a palm-size stubby ratchet for work in tight spaces. Overall length is 75.0 mm.
- Running a loose nut down is slow. TONE built a quick-spin dial into the head so you can spin the fastener with your fingertips before the final turns.
- Something is in the way. The handle end has its own drive square. TONE says you can combine it with a spinner handle or similar tool to get a swivel function or to work around obstacles.
- Sockets dropping off. TONE lists the RH3HSS3 as a socket hold type, so the socket is held on the drive while you work.
Is it right for your job?
- Good fit: 3/8" drive sockets in cramped spots, starting and running down fasteners quickly, reaching around an obstacle by driving the handle end with another tool.
- Not a good fit: breaking loose tight bolts by hand. A 75 mm handle gives little leverage; use a longer ratchet or breaker bar, or drive the handle end with one as TONE describes.
- Smaller drive: TONE makes a 1/4" (6.35 mm) version, the RH2HSS2 (60.0 mm, 50 g).

FAQ
What is the drive square in the handle for?
TONE says you can attach a spinner handle or similar tool to it, to add a swivel or to get around obstacles. In a Reddit r/Tools thread asking what the point of this short TONE ratchet is, the top answer compared it to a Z-type ratchet: you put it around the side of something and turn it with another ratchet.
How many teeth does the gear have?
Not confirmed. TONE's product sheet for the RH3HSS3 does not list the gear count, so we do not state one.
How long does delivery take?
We ship from Japan within 5–7 days, and most orders arrive in about 1–2 weeks.
