Chipbreaker Coolant Feed Drills

The benefits of providing coolant internally directly to the drill cutting edge

include higher cutting speeds (reduced times by up to 75%), higher feed rates,

longer tool life (3 to 10 times), and less frequent resharpening. In addition, they

provide a superior finish.

The coolant assists in clearing chips from the drill point, and its pressure forces

the swarf along the flutes of the drill, facilitating drilling to greater depths without

repeated withdrawal to clear swarf.

strength, and connect to all coolant systems.

Coolant can be provided by the normal coolant pump supplied with most

machines, using soluble oil. However, we recommend using a mist coolant at a

pressure of 550 to 800 kPa (80 to 120 psi). This method is clean and efficient,

eliminating the problem of collecting, filtering and re-using the coolant.
