X Drill Bit

1.The X-shaped structure has a more balanced contact point with the material when cutting starts, which enables better self-centering. This helps reduce sliding when the drill first contacts the workpiece, making the drilling position more accurate and effectively improving the burr condition at the hole entrance, thus enhancing the quality of the hole.
2.The X-shaped cutting edge is paired with an optimized chip flute. This design allows chips generated during the cutting process to be discharged more smoothly, reducing friction and entanglement of chips with the hole wall and drill bit. As a result, cutting resistance and heat accumulation are lowered, making the drilling process more stable.
3.The cutting part, neck, and shank of the X drill bit are made of wear-resistant hard metal material to ensure stability and drill life.
4.The X-shaped design effectively distributes the cutting force acting on the drill tip to four cutting edges, significantly reducing the load per unit of each edge.

Product feature and application

Structural features:

Alloy Blade: The head is embedded with four hard alloy teeth arranged symmetrically in an X-shape, forming multiple cutting edges.

Bit body: Made of high-strength alloy steel to withstand the high-frequency impact loads transmitted by the rock drill.

Application fields:

Mining: Drilling of blast holes for metallic ores (such as iron ore, copper ore, gold ore) and non-metallic ores (such as limestone, granite).

Tunnel and Underground Engineering: Excavation of projects such as railway tunnels, highway tunnels, subways, and hydraulic tunnels.

Large-scale infrastructure projects: rock excavation for water conservancy dams, power station foundations, bridge pile foundations, and large factory buildings.

Quarrying operations:Intelligent mining and secondary crushing of decorative stones such as marble and granite.

Production details

It has extremely strong resistance to radial abrasion, is not sensitive to whether the rock is homogeneous or has fractures, and has stable performance.

Suitable for extremely hard, hard and broken, and rock with well-developed fractures.

Why choose us

1.Excellent rock stratum adaptability
The X-shaped four-blade design evenly distributes impact force across multiple cutting edges, reducing the load on individual edges. This not only enables excellent performance in hard, highly abrasive rock but also allows it to easily handle complex rock formations with developed fractures and uneven hardness. It effectively reduces jamming of the drill bit and maintains stable drilling efficiency. This is its most significant advantage compared to Single-point chisel bits.

2.Outstanding durability and cost-effectiveness
The Tungsten carbide bit body is forged from high-quality alloy steel, with hard alloy blades embedded and welded on the head, endowing it with extremely high wear resistance and impact resistance. It has a longer service life in highly abrasive rock formations, reducing the cost and time for frequent tool replacement. Its outstanding radial wear resistance is particularly notable, which helps maintain the stability of the drill hole diameter.

3.Higher drilling efficiency and precision
The X-character symmetrical structure provides good centering, which helps in drilling straighter and more circular boreholes. This can improve blasting efficiency and engineering quality.

FAQ

Q: In what situations should the X Drill Bit be preferred over Single-point chisel bits or ball tooth type bits?

A: 1.Complex and fragmented rock formations: When rock fractures are well-developed and hardness is uneven, the X-shaped four-blade design can better balance the force, reducing the likelihood of getting stuck, and the drilling stability is significantly higher than that of Single-point chisel bits.
2.High-abrasive hard rock: Its structure provides excellent resistance to radial abrasion, resulting in a longer service life in hard and highly abrasive rocks such as granite and magnetite.
3.Pursuing comprehensive efficiency and stability: Compared with ball tooth bits, X-shaped bits have a wider adaptability in unknown or complex geological conditions, making them a more reliable choice. They are particularly suitable for drilling hard, highly abrasive rocks with heavy-duty rock drills.

Q: What are the essential operational precautions when using an X Drill Bit?

A: 1.Drilling Tips: When starting to drill, reduce the air volume (impact energy) of the rock drill. Once the drill bit is fully embedded in the rock, gradually increase it to normal parameters. This can prevent the alloy teeth from chipping due to excessively high local stress.
2.Abnormal Handling: If encountering abnormally hard foreign objects (such as rebar) or a sudden increase in resistance during drilling, stop the operation immediately for inspection, adjust the drilling position, and prevent damage to the drill bit.
3.Ensure smooth powder discharge: Maintain sufficient air pressure or water pressure for powder discharge. Inadequate powder discharge will cause rock powder to be repeatedly ground against the drill bit, leading to excessive wear and drill jamming.

Q: How to determine if an X Drill Bit needs resharpening or replacement?

A: 1.Grinding timing: When the width of the platform formed by wear on the alloy tooth cutting edge reaches a certain limit (for example, approximately 3 millimeters), it must be promptly removed for grinding. Continuing to use it will drastically reduce the drilling speed and increase energy consumption.
2.Scrap standards: The head diameter is significantly smaller than the root; the Tungsten carbide bit steel body is damaged.
