BK47 Bullet Tooth

xinruishanhe rotary drilling picks feature a classic stepped-shank design, perfectly compatible with mainstream equipment such as Sany, Bauer, and XCMG. The carbide tips possess excellent self-rotation sensitivity, enabling automatic "uniform circumferential wear" during operation to effectively prevent eccentric wear. Suitable for sand, pebbles, and hard rock foundation drilling, they are the high-performance choice for ensuring piling efficiency.

High-Performance Hard Rock Bullet Teeth: Guarding Your Drilling Profit with "Zero Pop-out & Zero Snapping"

The Ultimate Cutting Solution for Rotary Drilling, Longwall Mining, and Tunneling

In large-scale projects, cheap picks are the biggest "profit black hole." Every unplanned downtime for tool replacement represents not just tool wear, but massive costs in machine idling and labor. xinruishanhe picks are engineered specifically to solve these pain points.

How We Solve Your Pain Points?

1.100% Virgin Coarse-Grained Carbide

We exclusively use high-purity virgin tungsten carbide. This coarse-grained structure provides superior fracture toughness compared to common recycled materials.
It effectively prevents carbide chipping and cracking. Even when impacting hard boulders or extremely hard rock formations, it maintains the integrity of the cutting tip.

2.Integral Hot-Forged 42CrMo Steel Body

The tool body is precision-forged from high-performance alloy steel using heavy-duty presses and undergoes a professional gradient heat treatment process.
The forging process maintains continuous metal flow lines, ensuring the shank has the characteristic of "bending but never snapping" under extreme torque, completely avoiding structural failure in deep drilling.

3. Vacuum Brazing Technology

Carbide tips are joined using controlled-atmosphere vacuum furnace brazing. Each pick undergoes strict quality inspections to ensure the bonding strength of the joint.
This technology eliminates gas pores and oxidation in the joint, ensuring a superior wetting area and effectively locking the carbide in place. We guarantee an extremely low pop-out rate in normal operating conditions, ensuring your continuous operation.
