Description
RACEWAY TECHNOLOGY
After development and global 3rd-party testing, the IMPAKT design innovation has been proven to actively clear cuttings from the entire cutting face. With flushing speeds increased by 25%, the resulting penetration rate has been improved by an average of 18%.
RACEWAY SCIENCE OF FLUSHING
The IMPAKT face design is based on reducing the residence time of cuttings at the face. Raceway flushing quickly clears cuttings from the entire bit face for a lower Cuttings Residence Time (CRT) and more effective energy utilization.
TRADITIONAL FACE DESIGNS
Traditional bits have a center ‘deadpool’
Standard designs focus on clearing the gauge
Opposing pressure causes stagnation of cuttings on the face
This ‘deadpool’ creates a cushion against effective energy transfer
IMPAKT FACE DESIGN
Raceway ensures full-face flushing
Raceway design clears both the face and the gauge
Pressure and flow accelerate cutting removal
All buttons in contact with fresh rock maximize efficiency in each strike
