In mining, tunneling, construction, and underground engineering, different rock formations and working conditions require different cutting and drilling solutions.

At Milalion Drill Tools, we are continuously expanding our product portfolio to provide customers with reliable tools for a wide range of rock drilling, rock cutting, and excavation applications.

From tricone bits for drilling to TBM cutters and raise boring cutters for rock excavation, our product range is designed to cover multiple stages of the rock-breaking process.

One Supplier. Multiple Rock-Breaking Solutions.

Different applications require different cutting mechanisms.

For rotary drilling, roller cones provide repeated crushing and shearing action against the rock. In raise boring and TBM applications, disc cutters and cutter rings generate concentrated forces to fracture rock along the excavation face. For milling, trenching, road construction, and other mechanical excavation applications, bullet teeth and scrapers provide continuous cutting action.

MilaLion's product portfolio includes:

• Tricone Bits
• Raise Boring Cutters
• Cutter Rings
• TBM Cutters
• Single Roller Bits
• Bullet Teeth
• Scrapers

This allows us to support customers across open-pit mining, underground mining, raise boring, tunneling, foundation engineering, trenching, and other rock excavation applications.

1. Tricone Bits — Efficient Rock Drilling for Mining & Construction

Our Tricone Bits are developed for demanding drilling applications where penetration rate, service life, and total drilling cost are critical.

Available in different tooth structures, bearing configurations, and IADC designs, tricone bits can be matched to different formations and drilling parameters.

Typical applications include:

• Open-pit mining

• Blasthole drilling

• Water well drilling

• Geothermal drilling

• Construction drilling

• Other rotary drilling applications

Rather than focusing only on the purchase price of a bit, we focus on the factors that determine Total Drilling Cost (TDC) — including penetration rate, bit life, and drilling efficiency.

2. Raise Boring Cutters — Built for Large-Diameter Underground Excavation

Raise boring is one of the most demanding underground excavation processes, requiring cutters that can withstand high loads and continuous rock-breaking conditions.

Our Raise Boring Cutters are designed for raise boring applications and can be supplied in different configurations to match customer requirements and machine specifications.

Key considerations include:

• Cutter diameter

• Cutter ring design

• Bearing performance

• Carbide configuration

• Rock formation

• Machine parameters

The objective is simple: stable cutting performance and predictable cutter life under demanding underground conditions.

3. Cutter Rings — The Cutting Interface That Matter

The cutter ring is one of the most important wear components in rock-cutting systems.

Its geometry, material properties, heat treatment, and manufacturing precision directly influence cutting performance and service life.

MilaLion manufactures cutter rings for demanding rock excavation applications, with attention to:

Material → Heat Treatment → Geometry → Precision → Wear Resistance

By controlling key manufacturing processes, we aim to provide stable and consistent cutter performance in the field.

4. TBM Cutters — Supporting Modern Tunnel Excavation

Tunnel boring machines operate continuously under complex geological conditions.

The performance of the cutter system has a direct impact on:

• Penetration rate

• Cutter consumption

• Machine downtime

• Maintenance requirements

• Overall excavation cost

Our TBM Cutters are developed for rock excavation applications and can be customized according to cutter dimensions, machine configuration, geological conditions, and customer requirements.

From individual cutter components to complete cutting solutions, we work with customers to identify the appropriate configuration for their projects.

5. Single Roller Bits — Compact Tools for Engineering Applications

Single Roller Bits are designed for specialized engineering and drilling applications where conventional drilling tools may not provide the required cutting mechanism.

The rotating roller cutter breaks rock through crushing and rolling action, making it suitable for certain hard-rock drilling and engineering applications.

These tools can be used in areas such as:

• Foundation engineering

• Core barrel applications

• Hard-rock drilling

• Infrastructure construction

• Specialized drilling systems

Their compact design combines the advantages of roller cutting technology with specialized engineering equipment.

6. Bullet Teeth — Replaceable Cutting Tools for Continuous Rock Cutting

Bullet Teeth are widely used in mechanical rock excavation and cutting systems.

The carbide tip penetrates the rock while the cutting body transfers the impact and cutting forces generated during operation.

Performance depends on several factors, including:

• Carbide grade

• Carbide geometry

• Tooth body material

• Heat treatment

• Tip retention

• Rock abrasiveness

• Machine operating parameters

For this reason, selecting the right bullet tooth is not simply a matter of choosing a standard size.

The right tooth should match the machine, cutting system, and geological conditions.

7. Scrapers — Designed for Efficient Material Removal

Our Scrapers are used in applications where efficient material cutting and removal are required.

Depending on the application, scraper design can be optimized according to:

• Cutting geometry

• Wear requirements

• Material characteristics

• Installation configuration

• Operating conditions

With appropriate material selection and manufacturing control, scrapers can provide reliable cutting performance in demanding working environments.

From Raw Material to Finished Tool

Behind every drilling or cutting tool is a manufacturing process.

At Milalion Drill Tools, our capabilities cover multiple key stages of production, including:

Forging → CNC Machining → Heat Treatment → Precision Grinding → Carbide Insert Production → Assembly → Inspection → Surface Protection

This integrated manufacturing capability allows us to maintain better control over product consistency and quality.

For rock-breaking tools, small differences in geometry, hardness, carbide placement, interference fit, heat treatment, and dimensional accuracy can influence actual field performance.

That is why we believe that a good drilling tool is not simply manufactured — it is engineered around the application.

Engineering the Tool Around the Rock

There is no single cutting tool that is optimal for every formation.

Soft rock, medium-hard rock, hard rock, fractured formations, abrasive formations, and mixed geological conditions can all require different tool designs.

At Milalion Drill Tools, our approach is therefore based on three questions:

1. What are you drilling or cutting?

Rock type, compressive strength, abrasiveness, fractures, and geological variability all matter.

2. What machine are you using?

Machine type, RPM, torque, thrust, drilling pressure, and operating parameters influence tool selection.

3. What is your real target?

Is the priority penetration rate, cutter life, reduced downtime, lower consumption, or overall cost per meter?

The answer determines the tool configuration.

One Product Portfolio. Multiple Industries.

Our products are designed to serve customers across multiple industries:

Our goal is not simply to offer more products.

Our goal is to provide more complete solutions for customers working with rock.
