8 1/2″ IADC537 TCI Tricone Bit

Medium soft with low compressive strength and harder abrasive stringers,such as hard shale,hard gypolyte, soft limestone,sandstone and dolomite with stringers,etc.

Description

Cutting Structure

The wear-resistance of the teeth is enhanced with a premium tungsten carbide hard facing on the tooth surfaces for the steel tooth bit.

The durability of premium tungsten carbide inserts is improved with new formulas and new techniques for insert bit.

Palm back alloy full coverage

Multiple gauge protection with gauge trimmers on the heel of the cone, tungsten carbide insert, and hard facing on the shirttail increases gauge holding capability and bearing life.

Hard alloy nozzle

Can control the flow of water, reduce the heat in the process of the bit, increase the service life of the bit.

Screw thread

The upper part of the drill bit is provided with a thread for connecting with the drill string.

According to your requirements, we can modify the screw and also provide the corresponding conversion connector.

Hard-coated with a hard alloy layer

This can reduce the bearing wear and greatly improve the service life of the bit.

Silver-plated

This reduces wear and tear and improves the use of the drill bit compared to traditional processes.

Professional welding technology

According to the vulnerable point of the bit, we have professional welding personnel to focus on the protection, to provide a layer of protective film for the bit.
