—	Balanced penetration and stability are important
—	Anchor, blasting and geothermal drilling

Balanced Cutting + Stable Guidance

5-Wing

5-Wing Spiral PDC Bit

Recommended when:

—	More cutting contact points are required
—	Larger diameters are used
—	Drilling load is higher
—	More stable borehole performance is required

Higher Stability + Better Load Distribution

6-Wing

6-Wing Spiral PDC Bit

Recommended when:

—	Maximum drilling stability is required
—	Large-diameter bits are used
—	Formation conditions are more demanding
—	More cutting support is required

Maximum Cutting Stability + Heavy-Duty Structure

Wing Configuration Guide

Quick selection reference

Use this guide to match wing quantity with your drilling priorities and formation conditions.

Wing Type	Main Advantage	Recommended Conditions
3-Wing	Fast penetration	Soft to medium formations, general drilling
4-Wing	Balanced stability	Mixed and fractured formations
5-Wing	Higher load distribution	Larger diameter and heavier drilling loads
6-Wing	Maximum drilling stability	Large diameter and demanding drilling conditions

Applications & Formations

Used across anchor, blasting and water well drilling

This spiral PDC drag bit series is suitable for anchor drilling, blasting holes, slope support, water well drilling and geothermal drilling. Other applications include foundation pit drilling, grouting holes, mining construction and engineering drilling.

01 Anchor Drilling Stable guidance and balanced cutting for anchor and slope support drilling.	02 Blasting Holes Efficient drilling for blasting holes in broken and mixed formations.
03 Slope Support Reliable hole formation for slope support and foundation pit projects.	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

Suitable for mixed, weathered and fractured formations. The recommended wing quantity and cutter configuration depend on rock hardness, abrasiveness, fracture condition and drilling parameters.

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

⚠️ Note: The recommended wing quantity and cutter configuration depend on rock hardness, abrasiveness, fracture condition and drilling parameters. Please contact our engineers for formation-specific recommendations.

Available Sizes

Common sizes and custom diameters

Other diameters can be customized according to drilling requirements.

115 mm	125 mm	133 mm	138 mm	140 mm
152 mm	165 mm	171 mm	200 mm	250 mm
275 mm	311 mm	Custom Diameters Available

PDC Cutter Options

Cutter sizes and layouts to match your bit

The series can be equipped with different PDC cutter sizes and quantities according to bit structure.

Common Options

Available Cutter Configurations

—	1613 PDC cutters
—	Reinforced PDC cutter grades
—	Customized cutter quantity
—	Customized cutter exposure
—	Gauge protection cutters

Wing Count Effect

How Wing Count Affects Cutters

—	Larger wing count generally allows more cutter positions and improved load distribution.
—	Lower wing count provides a more open cutting structure and may support faster penetration in suitable formations.
