Release time:

2024-01-12

In-line drill bit is widely used in the domestic rock drill bit, its connection form is mainly tapered connection, it and tapered drill rod (commonly known as the finished drill) supporting the use. In order to correctly use the flat-shaped drill bit and ensure the normal service life, the following points must be paid attention: 1. Ensure good matching with tapered drill rod (the taper is consistent, the depth of drill rod inserted into the drill cone hole must be greater than 25mm, and the drill rod head should not reach the bottom of the drill hole), otherwise it is easy to lose the drill rod; Note: The drill products used and the tapered drill rod used are of the same manufacturer to ensure consistent taper and good matching.

Instructions for Use of One-word Drill Head

In-line drill bit is widely used in the domestic rock drill bit, its connection form is mainly tapered connection, it and tapered drill rod (commonly known as the finished drill) supporting the use.

In order to correctly use the flat-shaped drill bit and ensure the normal service life, the following points must be paid attention:

1. Ensure good matching with tapered drill rod (the taper is consistent, the depth of drill rod inserted into the drill cone hole must be greater than 25mm, and the drill rod head should not reach the bottom of the drill hole), otherwise it is easy to lose the drill rod; Note: The drill products used and the tapered drill rod used are of the same manufacturer to ensure consistent taper and good matching.

2. When drilling holes, the rock drill shall reduce the air volume to reduce the damage to the drill bit caused by high stress in the local part of the hard alloy sheet. When the drill bit is completely drilled into the rock, the normal air volume shall be used;

3, when the drill bit edge platform width ≥ 3mm, should be timely replacement or grinding, so as not to reduce the drilling speed, resulting in drill bit fragments, lobes, reduce the service life;

4. When using the drill bit, if you encounter foreign matters such as steel bars, you should adjust the drilling position to prevent the drill bit from being damaged;

5. When rock drilling is prone to jamming, the in-line drill bit should be replaced with cross drill bit or ball tooth drill bit;

6. For rocks that cause serious wear of straight-shaped drill bits, slow drilling footage and serious debris, consideration should be given to replacing other alloy brands of drill bits or using cross-shaped drill bits and ball tooth drill bits, and our company should be notified in writing in time so as to deal with them in time. The contents of the notice mainly include: 1) the type of rock drill used, wind pressure and air volume; 2), rock type and hardness, construction site (open air, underground, other), drilling construction method (downward, horizontal, mixed, other); 3), damaged drill bit type, quantity, life, damage form; 4), normal drill bit life average; 5), planned service life; 6), the average service life of other manufacturers. 7), my company's product model.

7, when the rock is soft, easy to drill, the use of the whole drill (drill head directly on the drill rod production) can greatly improve the drilling speed;

8. For vertical rock drilling, the use of integral drill can avoid the loss of drill head, and at the same time, it must ensure the normal discharge of powder, otherwise, the drill head will be seriously worn;

9, the drill bit in the rock drilling process should try to ensure that the water supply, in order to prevent the card drill, improve the service life of the drill bit and drilling efficiency;

10. Shandong Yanggu Jingang Brazing Tools Co., Ltd. can provide in-line braze bits with the same specifications, different brands and models of alloy sheets.
