Underreamer – Dart In GaugeMaster Driller

Durable and reliable, our GaugeMaster Driller underreamer gives you the greatest flexibility available down-hole. The GaugeMaster Driller can drill your production zone, clean out fill while circulating to bottom, and even drill or clean out ratholes to bottom. Save money by saving trips in and out, and get more done in less time. Here’s how:

  • With the dart in, the arms stays closed, sending 100% circulation flow to the drill bit. Drill or clean out the production zone with the same tool you’ll use for underreaming later. Underreamer works well with foam, with extensive history of success.
  • Heavy-duty tool will drill float equipment, saving trips in and out.
  • After drilling and clean-out is completed, begin underreaming process by pulling out the dart. This allows you to open the arms to their full extension, and you’re ready to begin underreaming.
  • Entire tool made from 4140 heat-treated steel, making a strong, durable tool.
  • Easily retrievable.
