The I-shaped drill bit is a widely used rock drilling bit in China, which is mainly connected in a conical form. It is used in conjunction with conical drill rods (commonly known as finished drill rods). In order to use the straight bit correctly and ensure its normal service life, the following points must be noted: 1. Ensure a good fit with the conical drill rod (with a consistent taper, the depth of the drill rod inserted into the drill hole must be greater than 25mm, and the head of the drill rod should not touch the bottom of the drill hole), otherwise the drill rod may be lost; Note: It is best to use the same manufacturer as the conical drill rod to ensure consistent taper and good fit. 2. When drilling holes, the rock drill should lower the air volume to reduce the damage to the drill bit caused by local high stress on the hard alloy sheet. When the drill bit is fully penetrated into the rock, the normal air volume can be used again; 3. When the platform width of the drill bit edge is ≥ 3mm, it should be replaced or polished in a timely manner to avoid reducing the drilling speed, causing fragments and cracks of the drill bit, and reducing its service life; When the drill bit shows a reverse cone, it should be replaced or ground in a timely manner, otherwise the drill bit will be severely worn, the drilling speed will be reduced, and even the drill bit will get stuck; 4. When using the drill bit, if encountering foreign objects such as steel bars, the drilling position should be adjusted to prevent the drill bit from being damaged; 5. When rock drilling is prone to jamming, the straight shaped drill head should be replaced with a cross shaped drill head or ball toothed drill head; 6. For rocks that cause severe wear, slow drilling progress, and severe fragmentation of the I-shaped drill head, consideration should be given to replacing other alloy grade drill heads or using cross shaped or ball toothed drill heads, and timely written notification should be given to our company for timely handling. The notice mainly includes: 1) The model, air pressure, and air volume of the rock drill used; 2) Rock type and hardness, construction location (outdoor, underground, other), drilling construction method (downward, horizontal, mixed, other); 3) The type, quantity, service life, and form of damage to the drill bit; 4) Average service life of normal drill bits; 5) Planned service life; 6) Average service life of other manufacturers. 7) Our company's product model. 7. When the rock is relatively soft and easy to drill, using an integral drill bit (made directly on the drill rod) can greatly improve the drilling speed; 8. For vertical rock drilling, using an integral drill bit can avoid the loss of the drill bit, while ensuring normal powder discharge, otherwise the drill bit will be severely worn; 9. During the drilling process, the drill bit should try to ensure the water supply as much as possible to prevent sticking, improve the service life of the drill bit, and improve the drilling efficiency; 10. Our company can provide the same specifications, different brands, and models of alloy plates with straight drill bits.

In order to use the integral drill correctly and ensure its normal service life, the following points must be noted: 1. Choose the overall drill according to the rock condition: the rock is hard, has strong abrasion resistance, and is easy to get stuck. Cross shaped or ball toothed drill can be selected; If the rock is soft and not stuck, you can choose a straight line shape; 2. When opening the hole, it should be stable and the air volume should be lowered. After the footage is 150mm, the normal air volume should work. Otherwise, it is easy to cause excessive local load on the hard alloy at the head, leading to damage; 3. When the drilling depth is ≥ 2000mm, sleeve drilling operation is adopted, with short drilling holes and long drilling holes continuing to extend the drilling to improve the overall service life of the drill; 4. When a platform with a width of ≥ 3mm appears on the edge of the sheet shaped alloy, stop grinding in a timely manner; When the ball gear alloy is severely worn, it should be stopped for grinding; When there is an inverted cone on the head, grinding should be stopped to eliminate the inverted cone, otherwise, the alloy will be severely worn and even the drill bit will be stuck; 5. Adjust the working wind pressure according to the rock conditions, with normal rotation, fast footage, non bending of the drill rod, and normal powder discharge as the standards; 6. When there is an early failure, please notify our company in writing in a timely manner. The notice mainly includes: 1) The model of the rock drill used and the actual working wind pressure; 2) The type and hardness of rocks, construction location (open air, underground, other), drilling depth; 3) Planned service life; Zhongmei Rock Drilling Materials Co., Ltd 4) Average normal service life; 5) Average service life of other manufacturers; 6) Early failure statistics: A. Failure location, lifespan, quantity; B. Wear condition of hard alloy (residual height).
