Steel Tooth Bit

Product Description

Huanyu Petroleum Machinery Co., Ltd. was established in 1998, located in Hejian which is in the middle of Cangzhou city, and enjoys good location and convenient transportation. Huanyu specializes in Tricone Bits, PDC bits, Drill rods, drill collars, engineering bits, stabilizers, for water well, oilfield, construction and underground foundation work all over the world. All of our products are in accord with API and ISO standards.

PDC bits series:
Feature: Improved support and retention
Advantage: Manage the magnitude cutter loading and bit torque.
Benefit: Improved bit durability and directional responsiveness
Advantage: Higher nozzle counts and/or fixed ports to best serve cleaning, cooling and cuttings evacuation requirements with available hydraulic flows. Allows for higher flow rates with minimal increase in pump pressure.
Benefit: Optimized ROP and bit life; Longer drilling intervals without need for tripping.
Feature: Diamonds are impregnated in the matrix behind the PDC cutters
Benefit: Increased footage drilled in abrasive applications
Feature: Larger than standard TFA.

114-117, 127
Soft Formation Tooth Bits
The 114-117 bits are used to drill low-compressive strength, soft formation. Long projection tooth lengths are used on high offset cones to provide the greatest penetration rates possible. Wear-resistant hard facing is used to control tooth wear. On the softest bits type this hard facing completely covers the bit teeth.

127
Medium-Hard Formation Tooth Bits
The 127 bits are used to drill high-compressive strength, medium hard formations. Short projection teeth with reduced crest length are used in this series of bit designs. Durable hard facing is applied to reduce tooth wear.

437
Soft Formation TCI Tricone Bits
The 437 TCI bits are used to drill low compressive strength, very soft formations. TCI bits maximize the use of both conical and chisel tungsten carbide inserts of large diameters and high projection. This cutting structure design, combined with maximum cone offset, result in high bit penetratione rates. The deep intermesh of cutter rows prevents bit bailing in sticky formations.

517
Medium Formation TCI Tricone Bits
The 517 features aggressive chisel tungsten carbide insert on the heel rows and inter rows. This design provides a fast drilling rate and added cutting strcture durability in medium-to-medium hard for-mationes. The HSN rubber O-ring provides adequate sealing for bearing durability.

637
Hard Formation TCI Tricone Bits
The 637 bits can be used to drill hard and abrasive forma-tions. Wear-resistant tungsten carbide inserts are used in the outer rows to prevent loss of bit gauge. Maximum numbers of hemispherical-durability and long life.

617
Medium-Hard Formation TCI Tricone Bits
The 617 feature robust chisel tungsten carbide inserts on the heel row and conical on the inner rows. This design provides a fest drilling rate and added cutting structure durability in medium to medium hard formations. The HSN rubber O-rin provides adequate sealing for bearing durability.
