Frequently Asked Questions (FAQ)

What is the settlement policy for core bits with unmatched thread sizes?

If the core bit thread cannot properly fit the client's barrel, the manufacturer will provide repair or replacement services.

Under what circumstances will matrix breakdown be covered for replacement?

A replacement is guaranteed if a piece exceeding 2mm x 2mm x 2mm breaks down from the matrix, provided that the breakdown is not caused by active drilling operations.

What issues are excluded from the core bit Quality Guarantee?

Problems arising from operating reasons (such as drill rod sticking, premature failure of the bit crown, uncleared hole bottoms), incorrect drilling parameters/techniques, thread damage by the operator, and normal matrix wear are excluded from the quality guarantee.

What types of diamond core bits are available?

We offer several types including Impregnated Diamond Type (Imp.), Surface Set Diamond Type (S.S.), Tungsten Carbide Type (T.C.), Polycrystalline Diamond Compact Type (PDC), Thermally Stable Diamond Polycrystalline (TSP), and Electroplated Diamond Type (E.P.).

What size gauges are included in the specifications?

The core bit specifications cover A-Gauge, B-Gauge, N-Gauge, H-Gauge, P-Gauge, S-Gauge, U-Gauge, and Z-Gauge. Detailed measurements for outside and inside diameters in both inches and millimeters are listed in our technical specification table.
