VEVOR BD-78D-C Torque Multiplier 1:64

The VEVOR BD-78D-C is a heavy-duty torque multiplier with a 1:64 ratio and 6800 N.m maximum output. It uses a 1-inch drive on both input and output ends. The set includes four sockets sized 21, 33, 38, and 41 mm plus an extension bar and rocking handle. It comes in a plastic storage case measuring 405 x 115 x 220 mm.

Who this suits and who it does not

This multiplier suits mechanics and technicians who need to remove stubborn lug nuts on heavy vehicles or industrial equipment. The high multiplication ratio lets one person generate extreme torque without powered tools. Buyers who only service passenger cars with standard wheel nuts will find the capacity excessive and the 1-inch drive incompatible with common ratchets.

Deciding specification: 1-inch drive and 1:64 ratio

The 1-inch square drive on both ends and the fixed 1:64 multiplication ratio are the critical specifications. They determine whether your existing sockets and reaction arms can connect and whether the output torque matches the fastener requirements. Verify both values against your application before purchase.

Questions about this item

Should I pick the 21 mm square socket or one of the 33 mm, 38 mm or 41 mm sockets for my lug nuts?

The set includes a 21 mm square socket plus 33 mm, 38 mm and 41 mm hex sockets; choose the size that matches the fastener you are removing.

What does the 6,800 N·m maximum output torque mean when I use the multiplier on a truck wheel?

It is the peak torque the tool can deliver at the 1" output square when the 1:64 ratio is fully loaded; actual torque depends on how much force you apply to the input.

How does the 1" drive input and output with a 1:64 ratio limit the torque I can apply?

Both input and output use a 25.4 mm square drive; the 1:64 ratio multiplies your input torque sixty-four times up to the 6,800 N·m rated maximum.
