The drills with internal cooling system should be used also with external cooling. Drill speed should be controlled from 600rpm(thick drills) up to 1000rpm(for fine drills). Cutting efficiency is coming bad by each use and bad drill will cause heat damages against bone. Only good drills should be used for operation. For very hard bones , it is recommended to use surgical burs prior to implant drills. Surgical burs will help easy drilling and long life. The fix screw of drill stopper is so small and it can not be bear a strong force. Drills can be used also without stopper.

FAQ
Q1: What is the advantage of internal cooling?
A1: Coolant reaches the cutting edge directly through internal channels, providing superior heat dissipation and typically extending tool life by 30 to 50 percent.
Q2: What coolant pressure is required?
A2: Minimum 10 bar for standard applications, 20-30 bar for deep holes above 5x diameter.
Q3: Can internal cooling drills be resharpened?
A3: Yes, multiple times. We recommend professional resharpening at our facility to protect coolant channel integrity.
Q4: What depth-to-diameter ratio can you achieve?
A4: Up to 12 to 1 in most materials. For deeper holes, we recommend our gun drill series.
Q5: Do you make step drills with internal cooling?
A5: Yes, please provide a drawing for a custom quote.
