What This Product Does

The 1005 general PDC cutters are 10.05mm diameter standard-grade diamond composite inserts manufactured for cost-effective construction and repair of small-diameter coal mining drill bits. The 10.05mm size and general grade together address the high-volume, cost-sensitive segment of the PDC cutter market where anchor bits, roof bolter bits, and thin-seam mining bits consume cutters in large quantities but operate in moderate formations that do not require premium diamond grades. These cutters are SUNGOOD TECH's most economical PDC insert for small-diameter bit applications.

Key Features & Technical Specifications

Cutter diameter: 10.05mm. Table geometry: convex. 

Diamond layer thickness: 1.0-1.2mm. Substrate: tungsten carbide with 6%-8% cobalt. 

Hardness: HRA >80. Thermal stability: up to 700 degrees C. 

Impact resistance: rated for light to medium impact. Braze interface: standard planar. 

Surface flatness: within 0.05mm. 

Quality control: batch sampling inspection. Available in standard grade only (thermally stable grade available through the customized 1005 product line).

Performance Advantages

On 30-42mm anchor and bolter bits in coal at 10-35 MPa, the 1005 general cutter provides adequate service life of 80-150m per bit, matching the typical replacement interval for anchor bit bodies in thin-seam mining. The 1.5mm diamond layer is sufficient for the moderate cutting loads generated by small-diameter bits in soft to medium coal. At the lowest unit cost in the SUNGOOD TECH cutter range, these cutters reduce per-bit construction cost by 25-35% compared to customized 1005 cutters and by 40-50% compared to imported premium cutters of equivalent size. For high-volume users consuming over 5,000 cutters per month, the cost savings are substantial.

Application Scenarios

High-volume anchor bit and roof bolter bit manufacturing for coal mines with moderate seam conditions. Small-diameter bit repair programs at mine maintenance workshops. Thin-seam mining operations where bit consumption is high but formation hardness is moderate. For small-diameter applications requiring premium quality or customized specifications, the 1005 customized PDC drill bit inserts PDC Cutters for coal mining provides 1005 customized PDC cutters with adjustable diamond thickness and grit size for demanding formation conditions. General-purpose exploration bit construction.

Problem-Solving Capabilities

Coal mines operating in thin seams under 1.5m typically use large numbers of small-diameter anchor bits, with each mine consuming 200-500 bits per month. At this volume, per-cutter cost becomes the dominant factor in the drilling budget because each bit requires 4-6 cutters and the bits are replaced frequently. Mines that purchase premium imported cutters for these applications often spend 2-3 times more than necessary because the formation does not demand premium diamond quality. A coal mine in Guizhou Province with 350 bits per month consumption switched from imported premium 10mm cutters to SUNGOOD TECH 1005 general cutters and reduced their monthly cutter expenditure by 48%, from approximately USD 12,000 to USD 6,200, with no measurable change in bit life or penetration rate in their 25-35 MPa seam.

Technical Support & Customization

SUNGOOD TECH offers tiered pricing based on monthly consumption volume. Standard packing in 200-piece lots for inventory convenience. Braze parameter guidelines provided for common small-bit body materials. Consignment stock arrangements available for high-volume customers.
