The rotary drill bit is an important part of the rotary drilling rig. Its main function is to quickly and accurately complete earth excavation, pile foundation construction and other tasks through high-speed rotation and strong digging force. According to the cutting angle and layout of the palm, it can be divided into: 90-degree U-shaped roller bits, 120-degree U-shaped roller bits, starry sky roller bits, etc. At the same time, we can also provide customized services according to the different needs of customers.
| Type | Application | Features |
| 90° U-shaped Roller Bit | Suitable for soft to medium-hard formations requiring steady drilling and fast cuttings clearance. | U-shaped groove with a 90° angle for stable cutting in alternating hard and soft formations, improves cuttings removal. |
| 120° U-shaped Roller Bit | Suitable for medium to softer formations, enhancing efficiency in clearing large volumes of cuttings. | U-shaped groove with a 120° angle for wider coverage, handles more cuttings for faster drilling in softer formations. |
| Full Cutter Layout (Starry Sky Roller Bit) | Suitable for hard rock formations, providing steady cutting force and high wear resistance. | Densely arranged cutters for full surface coverage, maximizes contact and cutting efficiency in hard rock. |
Bearings: Use high-precision rolling bearings, and the surface is inlaid with wear-resistant alloy and silver-plated to improve wear resistance.
Teeth: mixed tooth design to improve the wear resistance of the gear, specially designed for rotary excavation projects Design.
Surface design: strengthen the back nail design to protect the wheel body and extend the service life.
