Diaphragm

The Diaphragm (OEM 807 650 59) is a precision-made alternative spare part for rock drills and drifter equipment used in the most challenging mining and tunnelling environments. It is a precise internal part of the percussion or valve mechanism, managing the controlled motion and energy transfer behind drilling performance.

Made from hardened, precision-ground alloy steel, it endures high cyclic impact and pressure while keeping tight clearances and accurate operation. Supplied as an alternative spare part, it provides direct functional interchangeability and dependable performance at a competitive price.
