Key Features & Technical Advantages
Plasma Surfacing

Made of plasma surfacing powder, butt-welded by a plasma butt welder. During product use, the butt-welded layer protects the body, extending body life by up to 25% longer.

Tungsten Alloy Smelting

Rich experience in tungsten smelting and calcium carbide manufacturing. Alloy teeth forged with the highest impact and wear resistance of coarse particles and high precision steel. Refuses any recycled alloy materials.

42CrMo Material

Adopts 42CrMo as the material of the body. Special heat treatment process ensures high hardness and high toughness, wear-resistant, and break-resistant up to 100MPA on rock strata.

Petal Design

Unique & reasonable petal design, conducive to slag discharge during construction. Enhances independent rotation, reduces eccentric wear & gravel abrasion on the body to avoid early failure.

Frequently Asked Questions
Q: What is the advantage of the plasma surfacing process?
The plasma surfacing process uses surfacing powder butt-welded by a plasma welder. This process creates a high-performance protective layer that defends the body of the tool, extending its overall service life by up to 25%.
Q: What steel grade is used for the body of the drilling teeth?
The body of the drilling teeth is manufactured using high-grade 42CrMo steel. Complemented by a specialized heat treatment process, this ensures high hardness, robust toughness, and high wear resistance, preventing breakages even under 100MPa on rock strata.
Q: How does the unique petal design benefit construction?
The petal design facilitates efficient slag and waste discharge during construction. It enhances the independent rotation capability of the teeth, thereby reducing eccentric wear and avoiding early mechanical failure.
Q: Are recycled alloys used in the manufacturing of the teeth?
No. The alloy teeth are forged using only premium coarse-particle alloys paired with high-precision steel for optimal impact and wear resistance. Recycled alloy materials are completely avoided to ensure performance reliability.
Q: What is the significance of the brazing process used on these teeth?
The unique brazing process provides an extremely strong mechanical bond that prevents the alloy tip from loosening or falling out under the high vibration and stress encountered during rotary drilling.
