Description
JT21 DIRECTIONAL DRILLS
THE FASTEST WAY TO DRILL
With a 35% faster carriage speed than any drill in its class and 40% more downhole horsepower*, the JT21 will get you on and off the jobsite faster than ever before.
FEATURES & BENEFITS
35% FASTER CARRIAGE SPEED
35% faster than any drill in its class, the JT21's 215 fpm carriage speed sets a new standard for efficiency, so you'll experience reduced cycle times and increased jobsite productivity.
• With 21,000 lbs of pullback, 20,000 lbs of thrust and 2,250 ft·lbs of rotational torque, the JT21 is the most powerful drill in its class.
• Virtually Assisted Makeup and Breakout (VAM) removes the need for floats and sensors, increasing thread life by ensuring greater tooling longevity.
• A new design and lower center of gravity and increases stability
• Improved hydraulic efficiencies and a direct-drive motor deliver more downhole horsepower.
• An automatic grease bellows system is mess-free, allowing for more efficient use of grease.
• Multimode joystick controls let you choose a preferred operating style, and integrated LCD screens allow for better visibility into functions and diagnostics, giving you more control.
• An advanced telematics system provides data on machine performance so you have the insights you need to make quick decisions, resulting in better jobsite management and ROI.
• A larger displacement pump, generating 35 gpm and running at a lower RPM, increases the life of the pump and wearables.
• The 74-HP Deutz® engine ensures consistent performance even in difficult ground.
