Internal Cooling Aiguille Drill Bits 3DN
Product Name: Internal Cooling Aiguille Drill Bits 3DN
Material: High-Speed Steel, HRC52 or HRC65
Drill Bit Type: Internal Cooling Aiguille Drill Bit
Application Range: Widely suitable for drilling and processing metals and alloys.
Features:
Our internal cooling aiguille drill bits are made of high-speed steel material, produced using high-hardness alloys such as HRC52 or HRC65. They offer excellent cutting performance and wear resistance. With a specially designed internal cooling channel, these drill bits can significantly reduce the temperature and improve drilling efficiency. The internal cooling design prevents material clogging, ensuring long-lasting stability and extending the lifespan of the drill bit. Our internal cooling aiguille drill bits are suitable for cutting steel materials.
