Halco Dominator 880

The Dominator 880 is a general purpose hammer suitable for a wide range of air pressures. The Dominator 880 is a well drilling hammer with a mid to high range air volume. The one piece top-adaptor with N.R.V. (Non-Return-Valve) makes it easy to maintain and service the hammer. A choice of blank, 4 mm, 6 mm or 8 mm chokes can be fitted to provide varied air flow making the Dominator 880 a versatile hammer. The wide body diameter of the Dominator 880 allows for an increased piston weight and, therefore, an improved performance.
The unique air distributor integral with top-adaptor reduces requirements for shimming.

Suitable for operation at air pressures of 100 - 435 psi (7 - 30 bar).
Drilling diameters of 200 - 311 mm (7 7/8 - 12 1/4").
Available Shanks: IR QL 80.
