Ordered Array Is One Layer of the Core-Bit Specification
Ordered-array or ARIX-type describes how diamond crystals are positioned through the segment. It does not define the visible roof/turbo profile, matrix direction, barrel steel, attachment route or thread. Those fields must stay separate in the OEM drawing and sample record.
Catalogue-Backed Core-Bit Envelope
| Field | Available direction | Approval control |
|---|---|---|
| Diameter | Ø25–355 mm common; extended to Ø600 mm by drawing | Rig torque, stand travel and barrel wall |
| Working length | 400 / 450 mm common; other lengths by project | Rig stroke, extension and flushing |
| Segment | 10 / 12 mm height · roof, turbo, dimple or ordered-array option | Drawing, substrate and sample cut |
| Connection | 1¼-7 UNC / 1/2 BSP / M22 / 5/8-11 / M14 / M16 | Machine spindle or approved adapter |
| Joint route | Laser or high-frequency route by application | Wet/dry rating, rebar target and sample acceptance |
Open Threads and Proprietary Adapters
The catalogue evidence shows a broad hardware layer beyond the barrel: male/female adapters, quick-release conversions, dust-collector adapters, water-valve adapters and extensions. This is how an open 1¼-7 or 5/8-11 bit can be connected to a proprietary chuck when the approved adapter path exists.
See the thread and shank compatibility guide. Never describe an adapter as invisible: it changes stack length, run-out risk and maintenance points and must appear in the RFQ.
What the Catalogues Do and Do Not Prove
They prove ordered-array segment availability, thread breadth, diameter/length ranges and multiple joining routes. They do not prove a universal tube grade, ≤0.15 mm run-out, fixed weld penetration or a fixed performance multiplier. Those become production claims only after supplier documents and Zhonghuan's approved sample record support them.
Sample Acceptance
- Confirm rig, thread/adapter, diameter, length and water path.
- Specify profile and ordered/random placement separately.
- Test drilling rate through concrete and rebar, segment wear and barrel tracking.
- Approve cost per accepted hole before production.
