Key-type and keyless drill chucks
The corporate product catalogue separates keyed, keyless and locking chuck families. A series name does not establish interface or runout.
Company publication ↗Other precision components
Official navigation lists castings and power-tool component families; subsidiary and process scope must be checked per product.

Manufacturing & testing
The product centre presents separate component divisions. It does not establish that one plant makes every catalogue family.
For a chuck, agree mount geometry, clamping range, runout, grip performance and inspection method using the current drawing. These are buyer checks, not recorded test results.
No current certificate or model-level test report was independently verified. The historical table is a research reference, not a supplier approval.
Technical & quality documents
These are public-document leads. Current certificate validity and product applicability have not been independently established.
Current drawing and ordering status
Historical J3516A page provides mount and dimension rows.
Before approval
Request the current revision, active part numbers, mass unit and interpretation of L1/L2.
Factory and quality evidence
Company identity and catalogue are public; production allocation remains product-specific.
Before approval
Obtain current factory identity, inspection report, runout criteria and traceability.
What to confirm before an order
Buyer guidance from Honyawn Atlas — not a statement of the manufacturer’s commercial terms.
Specify the interface
Give exact mount, spindle, clamping range and required runout.
Confirm the revision
Resolve any ambiguous thread designation and obtain a dated drawing before interchangeability decisions.
Agree the supply route
Confirm active production, samples, inspection, packaging and commercial terms.
Have a specification ready?
Include the drawing or standard, quantity per size and delivery destination. Select quotation, samples or technical documents in the request form.
