Product Overview

The 30606LP-22 Wear-Resistant Hardfaced Rotary Drilling Bullet Tooth is a premium drilling wear part designed for abrasive ground conditions, foundation piling, cobble layers, and long-duration rotary drilling applications.

As part of the Wear-Resistant Rotary Drilling Teeth series, the 30606LP-22 features an advanced LP (Long Protection) design, combining an enlarged head structure, circumferential hardfacing protection, and a high-performance tungsten carbide insert to maximize wear resistance and operational life.

Built with a standard Ø30mm shank system and Ø38mm step collar, this rotary drilling tooth features an enlarged Ø60mm head diameter, 75mm gauge length, and 135mm overall length.

The tooth integrates a durable Ø22mm coarse-grain tungsten carbide insert with multiple circumferential hardfacing wear-resistant rings around the upper conical body. This protective structure effectively reduces steel body wash, abrasive erosion, and premature wear during continuous drilling operations.

Manufactured from precision drop-forged 42CrMo alloy steel, the 30606LP-22 provides excellent toughness, stable rotation performance, and extended service life for foundation drilling contractors in demanding geological conditions.

Technical Specifications

Key Features & Performance Advantages

1. LP Long Protection Wear-Resistant Design

The LP (Long Protection) structure provides enhanced protection for the tooth body and holder system during continuous drilling operations.

The reinforced design helps:

• Reduce steel body erosion
• Protect the carbide seat area
• Minimize holder wear
• Extend replacement intervals

This makes the 30606LP-22 an ideal choice for projects requiring long service life and reduced downtime.

2. Ø22mm High-Performance Tungsten Carbide Insert

The upgraded Ø22mm coarse-grain tungsten carbide tip provides excellent wear resistance and impact durability.

Compared with smaller carbide inserts, the larger tip offers:

• Increased carbide volume
• Better impact absorption
• Higher wear resistance
• Longer operating life

Suitable for:

• Abrasive rock
• Gravel layers
• Cobble formations
• Weathered ground conditions

3. Ø60mm Reinforced Head with Wear Protection

The enlarged Ø60mm steel head provides additional protection around the carbide insert and improves structural durability.

Benefits include:

• Improved resistance against abrasive wear
• Stronger carbide support
• Reduced body deformation
• More stable drilling performance

4. Circumferential Hardfacing Armour Protection

Multiple circumferential hardfacing rings form a protective wear-resistant layer around the upper conical body.

This armour system helps prevent:

• Steel wash caused by abrasive cuttings
• Surface erosion
• Carbide seat damage
• Premature tooth failure

The result is longer service life in abrasive drilling environments.

5. Optimized 75mm Gauge Length & Self-Rotation

The 75mm gauge length with 135mm total length provides improved clearance during drilling.

Advantages include:

• Efficient cutting discharge
• Reduced cutting resistance
• Stable penetration performance
• Lower wear concentration

Combined with standard Ø30mm holders, the 360° self-rotating design provides:

• Uniform wear distribution
• Self-sharpening effect
• Extended tooth life
