Product Description

Top quality !!! AQ BQ NQ HQ 7mm 9mm diamond pcb drill bit for mining drilling

Introduction of PDC drill bit:

♦	Steel body with hardening tungsten carbide surface(WC),make the drill bit both high strength and very strong abrasion resistance.
♦	Dedicated PDC cutter can improve the life and shield the risk of complex formation drill not passed.
♦	Raw materials: Alloy steel with a special treatment, achieve better mechanical properties (Rp0, 2: 1200MPa; Rm: 1100 MPa)
♦	Low torque spiral design and software designed tooth reduce the cutting edge wear & increase life
♦	(no repair life up to 8300M/pc).
♦	The unique parabolic crown-shaped design and tooth balance design keeps smooth drilling under high speed.
♦	(Speeds up to 30~40m/h.)
♦	The scientific drilling dynamic equilibrium design and hydraulic balance design make the drilling process more smooth.
♦	Authoritative API standard and ISO certification, quality and service will be better ensured.
