Product Overview

The 3060D12-22B Carbide Button Reinforced Heavy-Duty Hard Rock Rotary Drilling Tooth is a high-performance rock cutting tooth engineered for hard rock drilling, foundation piling, rock socket construction, and demanding rotary drilling applications.

Designed for extreme geological conditions, the 3060D12-22B combines a large Ø22mm tungsten carbide cutting tip with an advanced 12-piece carbide button reinforcement system around the conical head. This reinforced structure provides superior impact resistance, improves cutting stability, and protects the steel body from severe rock abrasion during heavy-duty drilling operations.

Unlike conventional rotary drilling teeth, the carbide button reinforced head design creates an additional protection layer that helps prevent premature body erosion, carbide seat damage, and structural wear when drilling in granite, basalt, quartzite, cobble layers, and other high-strength formations.

Featuring a reinforced Ø60mm head design, standard Ø30mm shank system, and precision forged 42CrMo alloy steel body, the 3060D12-22B delivers excellent durability, penetration performance, and service life for professional foundation drilling contractors in Europe, the Middle East, Southeast Asia, and Central Asia.

Technical Specifications

Key Features & Performance Advantages

1. Ø22mm Heavy-Duty Tungsten Carbide Cutting Tip

The 3060D12-22B features a premium Ø22mm coarse-grain tungsten carbide insert designed for aggressive rock penetration.

The large carbide tip provides:

• High impact resistance
• Excellent fracture toughness
• Strong rock crushing capability
• Reduced carbide breakage
• Extended cutting performance

It is suitable for challenging formations including:

• Granite
• Basalt
• Quartzite
• Limestone
• Hard sandstone
• Rock socket formations

2. 12 Carbide Button Reinforced Head Protection

The unique D12 carbide button reinforcement system integrates 12 tungsten carbide buttons around the cutting head.

This structure improves:

• Head wear resistance
• Impact protection
• Carbide seat stability
• Steel body durability

The carbide buttons help prevent:

• Excessive steel wash
• Abrasive erosion
• Premature head wear
• Cutting performance loss

This makes the tooth ideal for continuous operation in high-impact rock drilling environments.

3. Ø60mm Reinforced Heavy-Duty Head Design

The enlarged Ø60mm cutting head provides additional steel support around the carbide cutting structure.

Advantages include:

• Improved impact absorption
• Stronger carbide support
• Higher structural stability
• Longer service intervals

The reinforced geometry allows reliable performance under high torque and heavy drilling loads.

4. Forged 42CrMo Alloy Steel Body

The tooth body is manufactured from premium 42CrMo alloy steel using precision forging and heat treatment.

The high-strength steel body provides:

• Excellent bending resistance
• Superior fatigue strength
• High shear capability
• Long operational durability

It is designed to withstand severe rotary drilling conditions.

5. 360° Self-Rotating & Self-Sharpening Performance

The optimized tooth geometry allows smooth 360-degree rotation inside standard Ø30mm holders.

The self-rotation function provides:

• Uniform wear distribution
• Continuous self-sharpening effect
• Reduced flat wear
• Stable penetration efficiency

This helps maximize tooth service life and drilling productivity.
