What This Product Does

The 1005 customized PDC cutters are 10.05mm diameter diamond composite inserts manufactured to customer-specified parameters for coal mining drill bit construction and repair. At 10.05mm, this is the smallest standard PDC cutter in the SUNGOOD TECH range, used on small-diameter bits (28-50mm) for anchor drilling, roof bolting, and thin-seam coal mining where larger cutters cannot fit on the restricted bit face circumference. The customized designation means diamond layer thickness, grit size, substrate composition, and thermal stability grade can all be specified to match the user's formation and drilling conditions.

Key Features & Technical Specifications

Cutter diameter: 10.05mm. Table geometry: flat (convex available on request). 

Diamond layer thickness: 1 - 1.1mm standard (1.2mm available). 

Substrate: tungsten carbide with cobalt content adjustable from 6% to 10%. 

Diamond grit size: customizable from 4 to 25 microns. Hardness: HRA >80 depending on specification. 

Thermal stability:  700 degrees C thermally stable grade available. 

Braze interface: standard planar. Customization options: all parameters adjustable including special geometries (beveled edge, chamfered table) for specific cutting applications. 

Minimum custom order: 100 pieces.

Performance Advantages

The 10.05mm diameter enables cutter layouts on bits as small as 28mm, where 13mm cutters cannot physically fit on the bit face. On a 30mm anchor bit, the 1005 cutter allows 4 cutters across two wings where a 1308 cutter would only accommodate 2, doubling the total cutting length and increasing penetration rate by 30-40% in coal at 15-35 MPa. The customized parameters allow targeted optimization: finer grit (4-8 microns) for harder coal with stone bands, coarser grit (16-25 microns) for softer coal with higher abrasion, and higher cobalt substrate (8-10%) for impact-prone applications.

Application Scenarios

Small-diameter PDC bit construction and repair for anchor drilling and roof bolting. Thin-seam coal mining bits (28-50mm diameter). Bit rebuild programs for mining maintenance workshops. For slightly larger cutters suited to standard anchor bit sizes, the 1308 customized convex PDC Cutters drill bit Inserts for coal mining provides 1308 customized convex cutters with adjustable dome height for hard-inclusion coal seams. Specialized mining tools requiring small-diameter cutting elements.

Problem-Solving Capabilities

Bit manufacturers and mine maintenance shops that rebuild small-diameter anchor bits face a supply problem: the 10mm cutter size is less common than 13mm or 16mm, and many suppliers only stock standard-grade 10mm cutters with fixed specifications. When the mine formation requires a specific grit size or diamond thickness, the standard cutter underperforms and frequent bit changes drive up per-meter drilling cost. The SUNGOOD TECH 1005 customized cutter solves this by offering the same parameter flexibility available in larger cutter sizes but at the 10mm scale. A bit rebuilder in Inner Mongolia reported that customized 1005 cutters with 8-micron grit and 2.0mm diamond layer extended their 36mm anchor bit life from 80m to 200m in a seam with hard silica partings, cutting their per-meter cutter cost by 55%. The customized approach addressed the specific failure mode (diamond layer wear-through) rather than applying a generic small cutter.
