Introduction to Impact Drill Bit

Impact drill bit is the core component of pneumatic drilling rig, consisting of high-strength steel body and hard alloy cutting edge, which crushes materials by combining high-frequency impact and rotation.

According to the shape of the cutting edge, it can be divided into cross shaped, straight shaped, spherical tooth shaped, etc. The cross shape is suitable for medium hard rocks and concrete, with strong stability; Yi Zi excels in handling soft rocks and coal seams, with efficient cutting; The spherical tooth shape is resistant to hard rock and has outstanding wear resistance.

It is widely used in mining, construction, tunnel excavation and other scenarios, and can easily handle hard materials such as rocks and concrete. It is a practical tool for penetrating hard materials and opening up channels.

Instructions for using impact drill bits

Installation adaptation: According to the connection method of the pneumatic drilling rig, select the corresponding impact drill bit interface to ensure a firm installation without looseness and avoid detachment during operation.

Startup and Operation: Before starting the drilling rig, ensure that the drill bit is aligned with the drilling position and maintained at a vertical or desired angle. After starting, first touch the working surface at low speed, and then gradually increase the speed and feed force after the drill stably cuts in. For different materials, adjust the feed force. For soft materials, increase the feed force appropriately to improve efficiency. For hard materials, apply pressure slowly to avoid overloading.

Chip removal coordination: During the drilling process, the rotation and impact action of the drilling rig are used in conjunction with the chip removal groove to timely remove debris. If you find that the chip removal is not smooth, you can retract the drill bit appropriately, clean up the debris, and then continue the operation.

Precautions for impact drill bits

Inspection and maintenance: Before use, check whether the drill bit has cracks, broken edges, or other damages, and whether the cutting edge is sharp. If there are any problems, replace or repair them in a timely manner. After use, clean the debris and dirt on the surface of the drill bit, especially the residue in the chip groove, then apply anti rust oil and store it properly in a dry place to prevent rusting.

Safety protection: Wear protective equipment such as helmets, goggles, gloves, etc. during work to avoid flying debris and injuring people. In high-altitude operations or slippery environments, safety fixing measures should be taken to prevent the drilling rig and personnel from falling.

Avoid improper operation: Do not forcefully drill holes on materials that exceed the rated diameter of the drill bit to avoid damaging the drill bit and drilling rig. When encountering hard objects such as steel bars, do not forcefully impact them. Instead, slowly rotate and grind through or replace the appropriate drill bit to prevent it from cracking.

Cooling and heat dissipation: In hard materials or continuous operations, water cooling or oil mist cooling can be used to cool the drill bit, avoiding increased wear or performance degradation caused by high temperatures.
