The service life of a top hammer drill bits is affected by many factors, and it is generally difficult to give an exact fixed time.

The factors that affect the service life of a top hammer drill bits are mainly the following:

1. Usage scenario

Rock hardness: When working in rocks with higher hardness, the wear rate of the drill bit will be accelerated, and the service life will be shortened accordingly. For example, when used in extremely hard granite mines, the service life may be shorter than in limestone quarries with lower hardness.

Complexity of geological conditions: If the geological conditions in the operating area are complex, such as faults and cracks, the drill bit will be subjected to uneven stress during drilling and easily damaged, thereby shortening its service life.

2. Operation method

Feed speed and pressure control: Reasonable control of feed speed and pressure can extend the life of the drill bit. Too fast feed speed and excessive pressure will cause excessive wear of the drill bit and may even cause the drill bit to break.

Cooling and lubrication: During use, timely cooling and lubrication can reduce the temperature of the drill bit and reduce wear. If cooling and lubrication are insufficient, the drill bit will wear quickly due to high temperature, and the service life will be greatly shortened.

3. Drill bit quality

Material: High-quality drill bits are usually made of wear-resistant and high-strength materials, and their service life is relatively long. For example, a top hammer drill bits made of high-quality alloy steel or special alloy material may have a service life several times longer than a drill bit made of ordinary materials under the same conditions.

Manufacturing process: Advanced manufacturing technology can ensure the accuracy and quality stability of the drill bit and improve its service life. For example, drill bits produced using precision machining technology and a strict quality control system show better performance and longer life during use.

Generally speaking, if the use conditions are relatively ideal, that is, the rock hardness is moderate, the geological conditions are relatively simple, the operation is standardized and the drill bit quality is good, the service life of the top hammer drill bits may range from tens of hours to hundreds of hours. However, in harsh use environments, it may only be used for a few hours or even shorter.
