• Reduce fatigue with the light weight Centrotec chuck and decrease drilling/driving clearance with the compact design
• Centrotec bits extend directly into the drill spindle so they serve as an extension of the motor, significantly improving controllability and torque

• For pre-counterboring and flush screwing
