DC1924 Diamond spherical non-planar special-shaped teeth
Video
DC1924 is premium spherical non-planar diamond composite tooth (DEC), manufactured with identical mature HPHT high-temperature & high-pressure sintering technology as planar PDC composite compact sheets. With exclusive rounded dome non-flat profile design, it combines outstanding shock resistance and ultra-high abrasion resistance, serving as an ideal upgrade replacement for brittle conventional tungsten carbide teeth. It is widely configured as gauge-protection, anti-vibration and auxiliary rock-breaking inserts for PDC drill bits and DTH down-the-hole hammer bits across mining, onshore oil & gas and infrastructure foundation drilling projects.

Applicable Strata
- Medium-hard to hard intact rock: compact sandstone, limestone, dolomite (compressive strength:70–180MPa)
- High-abrasion complex strata: quartz-rich gravel layers, fractured broken hard rock interbeds
- Mining mixed formations: coal seams with hard stone partings, metal ore vein layers with irregular inclusions
- Alternating soft-hard interbedded formations for medium-deep well drilling
Core Product Advantages
Spherical Dome Buffer Structure for Excellent Impact Resistance
Arc spherical surface uniformly disperses instant impact force during drilling, effectively avoiding edge chipping and tooth fracture under frequent vibration in broken complex strata, passing strict repeated heavy-load impact durability test.
5–8x Longer Service Life Than Conventional Carbide Teeth
High-density HPHT sintered diamond layer reaches hardness HV10000+, outstanding anti-wear performance drastically cuts frequent cutter replacement and field downtime costs.
Double Functions: Gauge Protection + Auxiliary Rock Breaking
Unique non-planar spherical design stabilizes borehole diameter to prevent bit undergauge deviation while assisting primary cutters to crush hard rock particles, greatly improving overall bit stability and wellbore quality.
Superior High-Temperature Thermal Stability
Standard grade withstands continuous working temperature up to 750℃, restrains diamond graphitization and interlayer delamination under long-time continuous high-heat deep well drilling.
Precision Machining for Perfect Interchangeability
Strict CNC dimensional finishing with tight tolerance control, fully compatible with mainstream standard PDC and DTH hammer bit seat sizes for quick installation and interchange replacement.
Remarkable Overall Construction Cost Reduction
Long service life minimizes spare part stocking and rig round-trip frequency, lowering comprehensive project operating cost by 35%–55% compared with traditional carbide spherical buttons.
Precise Size Specifications
The DC1924 spherical non-planar composite tooth adopts fixed factory standard specifications: outer diameter 19.050mm, total height 23.820mm, spherical dome radius 5.4mm, and exposed effective diamond height 9.8mm. All finished products are machined with high-precision CNC, with strict dimensional tolerance control to ensure consistent batch quality, good interchangeability, and can be seamlessly installed as a shockproof and gauge protection insert for all standard PDC drill bits and down-the-hole hammer drill bits.
Material and Core Technology
Diamond layer uses 99.9% high-purity micron diamond powder for HV10000+ hardness. Substrate is optimized ultra-fine WC-Co carbide, balancing hardness and shock resistance.
Same sintering craft as planar PDC cutters. Diamond and carbide form integrated metallurgical bonding to avoid layer separation under heavy impact and abrasion.
Application Field
Oil & Gas Drilling
Suitable for shallow to medium-deep well operations on land. Works well in tight sandstone, interbedded strata and gravel-bearing formations. High temperature resistance avoids carbonization and delamination, reducing bit replacement and overall drilling cost.
Mining Drilling & Exploration
Ideal for mineral prospecting, tunnel drilling and mine water well projects. Perfect for high-abrasive hard rock such as granite and quartzite. Excellent impact resistance prevents edge chipping, serving longer life in fractured mining formations.
Geological Exploration & Sampling
High dimensional accuracy ensures stable drilling and regular borehole. Guarantees complete formation core sampling, fully meeting high-precision geological survey and resource exploration requirements.
Water Well & Infrastructure Engineering
Widely used in deep water wells, pile foundation drilling and construction projects. Efficient penetration in common rock layers, low wear and stable performance for long-time continuous site operation.
Universal Bit Matching
Compatible with mainstream PDC bits, core bits and drilling tools with good interchangeability. Custom sizes and chamfers are available to meet non-standard matching demands for different projects.
Customized Service
- Dimensional Customization: Adjustable diameter (18.5~19.5mm), total height (22~25mm), dome radius (4.5~6.0mm), exposed diamond height (8.5~11mm) per client’s drill bit drawing
- Performance Customization: High-wear version with thickened diamond layer; high-impact type with reinforced substrate formula; high-temperature customized grade resisting up to 850℃ continuous working heat

Customer Reviews
Mark Wilson | Oilfield Drilling Project Manager
We have been using their 16mm PDC cutters for a long time. They perform steadily in hard formations with much better wear resistance than other brands. Cutter chipping is greatly reduced, which effectively cuts down our overall drilling cost. Highly reliable for long-term cooperation.

FAQ
Q: What is the core application of DC1924 spherical non-planar composite tooth?
A: It is mainly installed as gauge protection, anti-vibration and auxiliary rock-breaking inserts for PDC drill bits and DTH down-the-hole hammer bits, stabilizing borehole dimension and improving overall drill bit service life to replace traditional brittle spherical carbide buttons.
Q: What is the key difference between DC1924 spherical insert and flat planar PDC cutter?
A: DC1924 owns rounded spherical buffering structure with superior impact resistance, specially suitable for fractured gravel-bearing complex formations and bit gauge protection; flat PDC cutter delivers faster shear penetration rate but poor anti-shock performance under uneven hard rock drilling.
Q: Is DC1924 available for high-temperature deep oil well drilling?
A: Standard DC1924 runs stably under continuous working temperature below 750℃; customized high-temperature modification version can withstand up to 850℃ for ultra-deep high-heat complex well projects.
Q: What formations are not fit for DC1924 long-term drilling?
A: It is not recommended for continuous drilling in ultra-soft pure clay and loose mudstone below 30MPa compressive strength, which will cause unnecessary premature wear and cost waste.
Q:Do you accept non-standard dimensional customization for special-designed drill bits?
A: Full customization is supported, including dimension parameter adjustment, spherical radian modification, diamond layer thickness change and surface coating customization according to clients’ exclusive drill bit design requirements.
