Unihammer
General Information
Why drill with air?
Little to no water needed
No refilling water when drilling tough ground (300 gallons will typically last all day, even in rock, on large drills)
No moving the bore around because of ground conditions. Soft clay to solid rock can be handled with one head
Less mess that mud system
If the ground or rock is tough, simply go bigger air. UNIHAMMER can handle up to 500 psi for the extreme jobs
How much air?
As small as a 400 cfm/200 psi to 1150 cfm/ 500 psi. Ground conditions and length determine your size needs
The control unit has a built-in pump that supplies from 1/2 gallon per minute to 3.5 gallons per minute of fluid to aid in cutting removal and cooling the sonde. No need to run the pump on your drill
A wireless remote control activates the supply valve at the control unit for your drilling air needs
Sonde housing handles both DCI and SubSite sondes, up to 19” and wireline compatible
Versus the competition
In Head to Head testing, the UNIHAMMER out produces the other air hammer systems on the market
Specific Metal Compound is used to ensure longer bit life and housing life
Designed to maximize airflow to provide downhole power, while saving compressor fuel costs by running smaller compressors
Specifically designed to handle more water for cuttings removal and cooling
Bit designed to grind up cuttings more efficiently and finer to help keep the hole clean
Designed and tested for everyday use, not just rock boring, giving you a better return on your investment
Sonde Housing has been verified by DCI to work with all DCI® sondes. Also compatible with all Subsite sondes.
4” Hammer
Highest Striker Weight to generate power
Runs on less air, 750 cfm / 350 psi compressor is ideal. This means smaller compressors and fewer fuel costs.
Designed to run with large volumes of water to help flush hole, or to compensate for groundwater
Oversized 5.5” head saves wear on the housing and provides better steering and longer life. Allows pullback of 4” pipe with no reamer.
3” Hammer
Designed to run on 400 cfm / 200 psi compressor
Small compressor options, allows a simple set up and low operating cost
Can turn a small drill like the 7x11 into a rock drill or aide in tough ground conditions that are not quite rock
Works all the way up to 24x40
4.5” cut allows pullback up to 3” diameter with no reamer
