Rock Drill Shank Adapter

A rock drill shank adapter is an essential connection tool between the rock drill and the drill rod in top hammer drilling systems. It transfers impact energy from the drill to the bit with maximum efficiency. As a professional shank adapter manufacturer, our factory supplies a wide range of T38, T45, T51, and ST58 shank adapters compatible with global brands like Atlas Copco, Sandvik, and Furukawa.

We focus on precision machining, strict quality control, and cost-effective factory pricing-ensuring every adapter performs reliably in the most demanding rock drilling environments.

A Shank Adapter (also known as a drill shank) connects the rock drill piston and the drill rod. It plays a critical role in energy transfer and alignment during rock drilling operations.

Our adapters are made from premium alloy steel, using advanced heat treatment and CNC precision machining, which ensures:

Excellent wear resistance

Stable impact power transmission

Extended service life under high stress

Common thread types include T38, T45, T51, and ST58, available for both male and female connections.

As a factory-direct shank adapter supplier, we integrate R&D, production, and export.
Every shank adapter goes through multiple quality stages:

Material Selection – high-grade nickel-chromium-molybdenum alloy steel.

Precision CNC Machining – guarantees perfect thread accuracy.

Vacuum Heat Treatment – improves hardness and impact toughness.

Thread and Surface Inspection – ensures consistent fitting and long life.

Thanks to our advanced equipment and professional engineers, our products achieve 20–30% longer lifespan compared to standard market adapters.
