Tungsten Carbide Drill Bit Inserts

High-impact tungsten carbide drill bit inserts for rock drilling, mining, quarrying, geological exploration, and abrasive drilling conditions.

High-impact tungsten carbide drill bit inserts for rock drilling, mining, quarrying, geological exploration, and abrasive drilling conditions.

Product Overview

Tungsten Carbide Drill Bit Inserts are wear-resistant cutting components designed for rock drilling, mining, quarrying, geological exploration, foundation drilling, and other demanding drilling applications. Manufactured from cemented tungsten carbide, these inserts provide a reliable balance of hardness, wear resistance, and impact toughness for severe drilling conditions.

Carbide drill bit inserts are commonly installed in steel drill bits, DTH hammer bits, top hammer tools, rotary drilling tools, roller-cone cutters, and other rock-penetration equipment. During drilling, the inserts are exposed to repeated impact, abrasive rock particles, high contact loads, heat, and changing geological formations.

Proper carbide grade selection, insert shape, exposure height, and press-fit dimensions are important for obtaining stable drilling performance and long service life. KENIN Carbide manufactures standard and custom tungsten carbide drill bit inserts according to customer drawings, samples, drill bit design, rock conditions, and operating requirements.

Applications

Tungsten carbide drill bit inserts are widely used in drilling equipment requiring high impact resistance, rock penetration capability, and long wear life.

Typical applications include:

Down-the-hole hammer drill bits
Top hammer drill bits
Rock drilling tools
Mining drill bits
Geological exploration drilling
Foundation drilling tools
Water well drilling equipment
Quarry drilling tools
Tunnel and construction drilling equipment
Rotary drilling tools
Roller-cone and tricone drilling tools
Hard rock and abrasive formation drilling

Custom Manufacturing

KENIN Carbide manufactures custom tungsten carbide drill bit inserts according to drawings, samples, drill bit structures, rock conditions, and drilling requirements.

Custom options include carbide grade selection, insert diameter, height, head profile, shank geometry, exposure height, press-fit dimensions, chamfer, tolerance, surface finish, and inspection requirements.

Available insert designs include spherical inserts, ballistic inserts, conical inserts, dome inserts, wedge inserts, chisel inserts, flat-top inserts, and other special-shaped carbide drilling components.

Frequently Asked Questions

Can tungsten carbide drill bit inserts be manufactured according to drawings?
Yes. KENIN Carbide can manufacture tungsten carbide drill bit inserts, carbide buttons, rock drilling inserts, DTH inserts, top hammer inserts, and other custom carbide drilling components according to customer drawings, samples, 3D files, or detailed technical requirements. Insert diameter, height, profile, shank geometry, tolerance, carbide grade, and surface finish can all be customized.
Which carbide grade is suitable for drill bit inserts?
The suitable carbide grade depends on rock hardness, abrasive minerals, impact load, drilling method, drill bit structure, rotational speed, feed force, and required service life. Grades such as YG8C, YG11C, and YG15C may be selected for different drilling applications, but final grade selection should be confirmed according to actual working conditions.
Can the insert profile and press-fit dimensions be customized?
Yes. Spherical, ballistic, conical, dome, chisel, wedge, flat-top, parabolic, and other special insert profiles can be customized. Insert diameter, overall height, shank shape, exposure height, press-fit dimensions, brazing base, and tolerance can also be produced according to the drill bit design.
What information is required for a quotation?
Please provide the drawing or sample, drill bit type, insert diameter, overall height, head profile, installation method, rock formation information, drilling method, required quantity, tolerance requirements, and expected service life.
What is the difference between a carbide drill bit insert and a carbide mining pick tip?
A carbide drill bit insert is generally installed in a drill bit for rock penetration and drilling operations. A carbide mining pick tip is typically installed in a mining pick, roadheader pick, shearer pick, or cutting drum tool for coal cutting, excavation, and continuous cutting applications.
Can carbide drill bit inserts be supplied for DTH and top hammer drilling tools?
Yes. KENIN Carbide can supply custom carbide drill bit inserts for DTH hammer bits, top hammer drill bits, mining drilling tools, quarry drilling tools, geological drilling tools, and other rock drilling assemblies according to required dimensions, carbide grade, insert profile, and installation structure.
Can carbide drill bit inserts be used in hard rock and abrasive formations?
Yes. Tungsten carbide is widely used for drilling inserts because it provides high hardness and wear resistance. The most suitable carbide grade, insert shape, exposure height, and drill bit design should be selected according to rock hardness, abrasive content, drilling impact, and expected service life.
