The Halco RC500 has been designed to give maximum performance in Exploration and Grade control applications.
The integral adaptor housing allows easy access to the long lasting sample tubes. Enhanced performance stems from a simple robust design that reduces complicated maintenance procedures, which result in more downtime.
The RC500 features improved flushing characteristics from high velocity air flow directed through the drill bit.
The RC 500 is offered with either Remet or Metzke threads on the sub adaptor body and an integral Drill Bit Catcher System for added peace of mind.
Top loading filter to prevent debris entering the hammer.
N.R.V (Non-Return-Valve) to prevent hammer from flooding.
Easy sample tube removal.
Piston and liner configuration for optimal airflow.
8 spline bit shank gives large drive area and reduces contact stresses.
Air Consumption
Suitable for operation at air pressures of 200 - 600 PSI (14 - 41 bar).
Drilling diameters of 137 - 189mm (5 3/8 - 7 1/2").
Bit Catcher to prevent loss of bit head if failure occurs and seals the hole for sample recovery.
