About Our Products
PDC Drag bit are also named PDC blade bit, with PDC cutter inserts on the blades. They are manufactured from forged high quality alloy steel and PDC cutter insert, plus state of art welding technology and multiple precision heat treatment to provide highest penetration rate and longest lifespan at roughest condition.
We can supply different diameter of 2-wings drag bit, 3-wings drag bit, 4-wings drag bit, and 6-wings drag bit.
