Description

The Diaphragm (OEM HB10G-70111) is a premium aftermarket replacement engineered for rock drilling and drifter rigs operating in the most demanding 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. As a cost-effective alternative component, it matches the form, fit and function of the original while maintaining high reliability.

Delkom manufactures the world’s highest-quality alternative rock drilling, drifter equipment and spare parts, exported to more than 100 countries. Contact us for availability, bulk pricing and technical support.
