BT Series Hammers

MAG-GRIP Rod Lifter

Great balance of simplicity and performance:

  • Most productive piston concept (or “Piston concept maximized penetration rate”)
  • Strongest QL/QLX 12-spline shanks, to maximize longevity/reliability/durability
  • 100% tubeless, no troublesome foot-valves.
  • Light and simple, easy to handle and support
  • Maximum wear life, hard-faced drive chucks and back reaming buttons

Features

1 . TOP SUB

Back reaming buttons protect the top sub against wear when pulling out of the hole.

2. SOLID PISTON

Most productive piston concept, maximizing penetration rates.

3. GUIDE SLEEVE

Serves the same function as the plastic foot valve, but is a much more reliable solution.

4. DRIVE CHUCK

Hard facing protects the drive chuck and extends the life of the hammer.
