BETA 728-15 iskuvähennysadapteri 3/4"F x 1/2"M Cr-Mo

Mismatched drive sizes between your impact wrench and socket can bring work to a halt. The BETA 728-15 Impact Reduction Adapter bridges that gap by converting a 3/4-inch female square drive to a 1/2-inch male square drive, letting you use smaller sockets on larger tools without compromising strength. Machined from chrome molybdenum steel and finished with black phosphate, it withstands extreme impact torque while resisting corrosion and wear. A ball detent ensures the socket stays locked on during high-vibration operations, and the compact 45 mm length allows access in tight spaces. Compliant with DIN 3121 and ISO 1174, this adapter is a dependable link in any professional automotive, industrial, or mechanical environment.

Who is it for

Professional mechanics, heavy equipment technicians, and industrial maintenance crews who regularly use impact wrenches and need to adapt between 3/4" and 1/2" drive sizes. It is also suitable for serious DIY enthusiasts working on trucks, agricultural machinery, or construction equipment where high torque and durability are non-negotiable.
