Patents and intellectual property
The self-holding, self-driving drilling system is a patented invention, not a configuration.
The core invention
The foundational grant is US11253978B1, Self-holding and self-driving drilling system, assigned to GRABO Ltd. The title states the claim precisely: a drilling system that both retains itself on the work surface and drives its own feed.
Corresponding national filings include CN 2022100312703 in China, which has been granted, together with a divisional (CN 2026104352765) and a utility model (CN 2026205607771). Applications have also been filed in Europe, Canada and Japan.
Design rights
The VACDRILL Press form is protected by US design patent D968,485 S, with corresponding design filings in China and the EU. Design rights protect the appearance; the utility patents protect the mechanism.
Trademark
VACDRILL is the subject of US trademark application 90613513. GRABO technologies by 49-plus countries' registrations are described at GRABO.com/IP.
Why it is on this page
Buyers of professional tools reasonably ask whether a capability is genuinely novel or simply assembled. In this case the mechanism is the subject of granted patents in multiple jurisdictions, which is a matter of public record and can be checked independently.
Questions about this
Can I verify these patents independently?
Yes — granted patents are public records. US 11,253,978 B1 and the design patent D968,485 S can both be looked up through public patent databases.
Does a patent mean the tool is better?
It means the mechanism was found novel and non-obvious by an examining office. That is evidence of genuine invention rather than assembly, but performance is a separate question you should judge on the specifications and your own trial.
