Diaphragm

The Diaphragm (OEM HD612-07006) is a high-quality alternative spare part built for rock drills and drifter rigs working under the toughest mining and tunnelling conditions. 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. Offered as an aftermarket alternative, it delivers full interchangeability and proven durability at a more competitive cost.

Delkom produces premium alternative rock drilling and drifter equipment and spare parts, shipped to over 100 countries worldwide. Get in touch for stock availability, bulk pricing and technical assistance.
