| Grade | Grain size (µm) | Effective diameter (mm) | Published application lead |
|---|---|---|---|
| GC001 | 1 | 58 | Ultra-precision / high-gloss cutting |
| GS005 | 5 | 58 | Low-silicon aluminium, copper alloys, plastics |
| GA025 | 25 | 58 | Aluminium alloys with >14% silicon; composites |
Effective diameter comes from this grade table. Other pages discuss larger developed diameters; no 74 mm option is assigned to these grades without confirmation. PCD layer and total thickness are not stated.
Original comparison source ↗Selected GC001, GS005 and GA025 grades have different grain sizes and application guidance. Effective blank diameter is not a finished cutting-tool diameter.
Company publication ↗The company profile separately lists drilling compacts, drawing dies and precision tools. Their specifications must be checked individually.
Company publication ↗The following identity information is attributed to the company website. It does not replace registration or supplier approval checks.

The cutting-material page describes a PCD layer bonded to a cemented-carbide substrate using high-pressure, high-temperature sintering. Confirm grade composition and any subsequent cutting or grinding operations.
The quality page describes a testing centre and inspection controls, and names ISO9001, ISO14001 and ISO45001. Current certificate numbers, expiry dates and site scope have not been established.
The R&D page describes development of superhard materials and improved products. Agree a workpiece-specific trial and acceptance criteria; published application examples are not a guarantee of tool life.
These are public-document leads. Current certificate validity and product applicability have not been independently established.
The selected online grade rows state grain size, effective diameter and application leads.
Request current grade sheet, total and PCD-layer thickness, flatness, diameter tolerance and usable edge allowance.
The quality page describes inspection and management systems.
Obtain current certificate copies with scope/site and lot-level dimensional/material inspection records.
The catalogue differentiates grade application areas.
Confirm workpiece alloy, silicon content, interrupted cutting, finish target, tool geometry and trial conditions.
Buyer guidance from Honyawn Atlas — not a statement of the manufacturer’s commercial terms.
Specify full-disc blank, cut segment or finished tool; attach a drawing and required edge preparation.
State alloy/composite, hardness, silicon content, operation, cutting conditions and surface-finish target.
Confirm effective versus outside diameter, layer thickness, substrate, tolerance and edge allowance.
Request sample quantity, traceability, MOQ, pricing, lead time, packing and producing entity.
Include the drawing or standard, quantity per size and delivery destination. Select quotation, samples or technical documents in the request form.
