HDD drilling tools
Products for any type of directional drilling conditions.


Horizontal Directional Drilling Equipment
Over the years Epiroc have set the standard on many Horizontal Directional Drilling projects involving hard rock and difficult conditions. You can rely on Epiroc's technical expertise – any time – anywhere. Their products are the result of decades of drilling research and development and are manufactured in their world class manufacturing facility.
Epiroc have a broad range of horizontal directional drilling (HDD) equipment that are specifically designed and matched for any type of drilling condition.
The product’s versatility match the drilling needs to optimize the customer's productivity.
- Epiroc know the drill when it comes to horizontal directional drilling tools for your HDD drilling.
- Epiroc directional drill bits come with a large selection of cutting structures.
HDD drill bits
Epiroc offer a complete line of HDD pilot bits ranging from 3⅞" to 17½" in diameters. The pilot bits are specially designed for tough drilling conditions encountered during the horizontal directional drilling.
The pilot bits consist of milled tooth products for soft to medium rock and TCI products for medium to hard formations.
HDD milled tooth pilot bits
Epiroc have a large selection of HDD drill bits, such as milled tooth pilot bits for soft and unconsolidated ground formations. The pilot bits have an optimized shirttail protection, hard metal on the bevel, and inner rows of the cones to withstand the harsh drilling conditions that are typically encountered in the HDD application.
The milled tooth pilot bits are designed with a compensation system to allow for deep drilling without adding pressure to the internal sealing components.
The bearing system is a greased frictional bearing that allows drillers to apply higher loads at higher rotational speeds without damaging the internal components.


Features | Benefits |
---|---|
Full armor protection | Wear protection for bit body and sealing components. |
Hard metal on teeth | Longer lasting cutting structure for more drilling. |
Compensation system | Allows to drill deeper without damaging grease seals. |
Frictional bearing | Higher load bearing capacity. |
Greased bearing | Higher rotation speed bearing capacity. |
Competitive pricing | High productivity at low cost. |
Small to medium diameter pilot bits


Feature | Benefits |
---|---|
Full armor protection | Wear protection for sealing components. |
Large selection of cutting structures | Optimum matching for every ground condition. |
Compensation system | Allows to drill deeper without damaging grease seals. |
Frictional bearing | Higher load bearing capacity. |
Greased bearing | Higher rotation speed bearing capacity. |
Competitive pricing | High productivity at low cost. |
Fluid nozzles | Capacity of handling application with high fluid flows. |
Medium to large diameter pilot bits
Epiroc engineers have combined the hard rock cutting structures, strongest shirttail wear protection and the leading edge bearing and seal package technology to create a pilot bit specifically designed for the HDD market.
The result is the direct shot (DS) product line which drills faster and longer at lower total drilling cost per operation.


Feature | Benefits |
---|---|
Industry proven sealed bearing | Higher quality resulting in better performance. |
Silver plated bearing surfaces | Longer lasting bearings at higher RPMs. |
Proprietary carbide shapes and grades | Prolonged cutting structure and integrity. |
Proprietary high load and pressure grease | Higher bearing capability in tough drilling conditions. |
Full armor protection package | Optimum bit body protection for harsh horizontal drilling conditions. |
Jet nozzle design | Capacity of handling application with high fluid flows. |
Pressure compensated system | Allows to drill deeper without damaging grease seals. |
Random bit third cutters
TCI random bit thirds have cutting structures designed to outperform any cutter in the industry, their strategically placed inserts create optimum cutting size that can be easily cleaned and transported for faster drilling.
Random cutting structures reduce the vibration on the machine and increase the rate of penetration removing more formation per revolution than any other cutter in the industry.


Feature | Benefits |
---|---|
Random cutting structure | Higher rates of penetration with lighter loads and smaller chip size generation easier to clean the hole. |
Proprietary carbide grade and shapes | Prolonged cutting structure and bit integrity. |
Industry proven seal packages | Higher quality resulting in better performance. |
Avaliable as pressure compensated or pressure relieved and re-greaseable | Allows to drill deeper without damaging seals while maximising bearing life. |
Proprietary high load carrying grease | Prolonged bearing life. |
Full armor protection | Optimum bit body protection for harsh horizontal drilling conditions. |
Jet nozzle designs | Capacity of handling application with high fluid flows. |
HDD bit kits
Bit kits are pilot bits that are used for building cutting tools, like hole openers, core barrels among others.
The Epiroc bit kits are specially manufactured to have high quality bearing and cutting structures, without adding any unnecessary processes that might damage the vital features of the cutters.
