The TiNAl coating on these drill bits provides a low-friction surface and is suitable for drilling most materials. These drill bits have holes that allow coolant to flow to their tip to reduce heat and help clear chips during drilling. Spiral-flute drill bits evacuate chips as the bits drill into a workpiece.
