REVERSE Circulation Hammer Bit is a specially designed drill bit that is typically used in conjunction with a Reverse Circulation DTH Hammer to achieve efficient rock fragmentation and debris removal during drilling operations. The following is a detailed introduction to this type of drill bit:

1、 Working principle
The through type reverse circulation down the hole hammer drill bit is driven by compressed air or other gas to move the piston inside the hammer up and down. This movement generates strong impact energy, which is transmitted to the drill bit, thereby achieving rock fragmentation. At the same time, the drilling cuttings are discharged from the inside of the drill rod through a reverse circulation method, which improves the drilling efficiency.
2、 Main features
Efficient crushing: The drill bit is made of high-strength and wear-resistant materials, which can withstand large impact and friction forces, achieving efficient crushing of rocks.
Reverse circulation chip removal: Through the internal channel of the drill rod, the drill chips are discharged from the bottom of the drill rod, avoiding the accumulation of drill chips in the borehole and improving drilling efficiency.
Strong applicability: This drill bit is suitable for rocks of various hardness and abrasion, and can maintain stable performance under harsh drilling conditions.
Easy to maintain: The structure of the drill bit is simple, easy to disassemble and clean, reducing maintenance costs.
3、 Application Fields
The through type reverse circulation down the hole hammer drill bit is widely used in mining, road construction, water well drilling, and slope protection fields. Especially in situations where efficient drilling and chip removal are required, this drill bit can demonstrate its unique advantages.
4、 Purchase suggestions
Brand selection: Choose well-known brands and reputable manufacturers to ensure the quality and performance of drill bits.
Specification matching: Select appropriate drill bit specifications and models based on specific drilling requirements and equipment models.
Quality inspection: Conduct a quality inspection on the drill bit before purchase to ensure that its appearance is undamaged and its dimensions meet the requirements.
After sales service: Understand the manufacturer’s after-sales service policy in order to receive timely support and solutions when encountering problems during use.
In summary, REVERSE CIRCULATION HAMMER BIT, as an efficient and durable drilling tool, plays an important role in multiple fields. Choosing the appropriate drill bit and using and maintaining it correctly will help improve drilling efficiency and reduce costs.
