Key Features

Spiral profile for broken formations

Six design advantages behind the Four-Wing Spiral PDC Drag Bit.

01 / 06

Four-Wing Balanced Structure

The four-wing layout distributes cutting loads more evenly and improves drilling stability.

02 / 06

Spiral Curved Blade Profile

The spiral blade geometry supports efficient cuttings evacuation and smoother drilling in broken formations.

03 / 06

1613 PDC Cutters

Large 1613 PDC cutters provide aggressive cutting action and good wear resistance.

04 / 06

Stable Drilling in Fractured Formations

The blade and cutter arrangement is designed to maintain stable contact in mixed and broken rock conditions.

05 / 06

Multiple Size Options

Available in multiple diameters from approximately 115 mm to 250 mm.

06 / 06

Custom Connections

Connections can be customized according to 76, 89 and other drill rod systems.

Applications & Formations

Used across blasting, anchor and broken formation drilling

This four-wing spiral PDC drag bit is suitable for blasting holes, anchor drilling, slope support, foundation pit drilling, grouting projects, water well drilling, geothermal drilling, engineering construction and general non-coring drilling.

01 Blasting Hole Drilling Stable drilling for blasting holes in broken and mixed formations.	02 Anchor Drilling Reliable hole formation for anchor and slope support drilling.
03 Slope Support Stable guidance for slope support and foundation pit drilling.	04 Water Well Drilling Efficient penetration for water well projects in mixed formations.
05 Geothermal Drilling Stable drilling performance for geothermal borehole and energy projects.

Suitable Rock Formations

Designed for mixed, fractured and medium-hard formations. Selected granite-bearing or fractured formations depending on cutter configuration and drilling conditions.

Sandstone	Backfill	Mudstone	Limestone
Weathered Rock	Fractured Formations	Selected Granite-Bearing Mixed Formations

⚠️ Note: Suitable for selected granite-bearing or fractured formations depending on cutter configuration and drilling conditions. Actual drilling performance depends on rock hardness, abrasiveness, fractures, drilling parameters and operating conditions.

1613 PDC Cutter Design

Large 1613 cutters as primary cutting elements

This drill bit uses 1613 PDC cutters as the primary cutting elements. Cutter quantity increases with bit diameter to maintain cutting coverage and drilling stability.

1613 Cutters Strong Rock-Cutting Capability The larger cutter structure provides strong rock-cutting capability and efficient penetration in mixed and broken formations.	Wear Resistance Good Wear Resistance 1613 PDC cutters provide good wear resistance and stable cutting performance in mixed formations.
Cutter Quantity Scales with Bit Diameter Cutter quantity increases with bit diameter to maintain cutting coverage and drilling stability.

Spiral vs Standard Four-Wing

Which four-wing PDC bit should you choose?

The final bit design should be selected according to formation hardness, fracture conditions, abrasiveness and drilling equipment.

Spiral Four-Wing

Spiral Four-Wing PDC Bit

More suitable for:

—	Broken formations
—	Mixed formations
—	Better cuttings evacuation
—	Anchor and blasting projects
—	Projects requiring improved drilling stability

Standard Four-Wing

Standard Four-Wing PDC Bit

More suitable for:

—	Relatively intact formations
—	General water well drilling
—	Standard grouting and construction drilling

⚠️ Note: The final bit design should be selected according to formation hardness, fracture conditions, abrasiveness and drilling equipment.
