Flat Bottom Drill Bits

Flat Bottom Drill Bits feature a flat front design, enabling the direct machining of flat-bottomed holes (such as countersunk holes and stepped holes) without the need for secondary processing. The angle between the main cutting edge and the secondary cutting edge typically ranges from 90° to 180°, ensuring the flatness of the hole bottom. The spiral groove design, combined with the chip-breaking groove, ensures smooth chip evacuation and prevents clogging. The use of coating technology makes it more suitable for machining high-hardness materials, extending the tool's lifespan.

Features:

• Capable of directly machining flat-bottomed holes (e.g., countersunk holes, stepped holes) without secondary processing;

• Chip-breaking groove design, resulting in short, fragmented chips and smooth chip evacuation;

• Low single-pass machining cost with high comprehensive efficiency;

• Carbide material with coating design, suitable for machining high-hardness materials.
