Pilothole Bit Services / Transco Manufacturing Distributor
Pilothole Bit Services is a USA Distributor
2018 TRANSCO placed inventory into Lafayette USA in partnership with Pilot Hole Bit Services including a full range of TRANSCO medium and hard rock HDD Hole Opener bodies, HDD Reamers and cutters.
Transco is a well known manufacturer with a reputation second to none. Instead of having 3 separate reamers for 3 different formations, with Transco you can just change out the cutters from Mill-tooth to TCI or PDC and you are back to work in minutes. Gone is the worry and expense of having 2 or 3 reamers on the job for backup! Transco is API and ISO certified.

Hole Openers
 TRANSCO Designs and manufactures a very large range of H.D.D hole openers to suit any of your requirements. From hole openers to suit midi HDD rigs to Maxi Rigs in both Integral and fabricated body. TRANSCO designs and manufactures all hole opener components with the exception of carbide inserts, seals, some bearing parts and raw steel. That gives us the ability to change any aspect of our tool design if required for special purpose applications. Before making cutter design changes to improve performance there must be a standard or baseline and a good reason for the change. TRANSCO has been making high quality HDD drilling tools since 1998. Our existing tools qualify as baselines. We developed a method for describing, analyzing and comparing cutting structures of different diameter tools made by different manufacturers that allow us to make logical changes and anticipate the results.

Fabricated Style Hole Openers

Transco Manufactures fabricated body hole openers from 26" through to 72' plus hole size, dressed with Transco Manufactured field replaceable cutters featuring Transco's patented cutter retention system Components are manufactured to API Spec 7-1 4145H specification with mandrel steel ex AISI 4145H certified alloy bar All connections cut in accordance to API . Transco made the first smooth barrel hole openers for drilling in large hard cobbles and hard broken formations. The smooth barrel surface would not hang up on broken formation and falling rock. The result was reduced torque, smoother operation and more efficient drilling. These advantages carried over into all types of formations drilled. Transco made this the standard body design for all its hole openers 26” and over in 2007. Additional advantages were noticed as more holes in varied formations were drilled. The stabilization of the barrel gave straighter holes. The large smooth area of the barrel does not dig into the bottom side of the bore during stationary rotation – fewer key seats. The barrel hole opener makes smoother borehole walls than traditional hole openers causing less friction for the product pull and allows a reduced reamed hole size to product pipe ratio in competent ground. TRANSCO barrel hole openers drill faster, straighter, smoother and longer bores with less torque than any other hole opener on the market.
