STAGETM WATERWAYS
Twin-TaperTM Window
Dramatically improves flushing, forcing debris through the windows while keeping the bit face clear and reinforcing the inner diameter.
• Increases the surface area of the inner diameter of the bit resulting in wear resistance in all ground conditions
• New window geometry prevents debris from clogging the windows
• Windows feature rounded corners to increase strength
• Window distribution has been refined, increasing crown strength
RazorcutTM Face Design
The patented design is ready-to-cut right out of the box and improves tracking and balance in the hole.
Crown Height
• 16mm crown height for shallow holes
• 25mm crown height delivers the most productive bit in the industry – longer lasting, faster cutting, and great stability at any hole depth.
Face Discharge (not pictured)
Face discharge improves core recovery in soft and/or broken ground.
Window Layout
Window distribution and shape have been redesigned for optimum performance in any ground condition.
