How the VACDRILL works
The engineering behind a drill that anchors itself: vacuum attachment, guided feed, depth control and dust capture — plus the patents that cover them.

How vacuum anchoring works
Vacuum anchoring explained: why 0.8 bar of vacuum under a sealed pad produces up to 45 kgf of holding force, and what …
The self-driving feed mechanism
How the VACDRILL advances its own bit along a guide column instead of relying on operator feed force.…
The drill depth sensor
How the VACDRILL's depth sensor sets and holds a target hole depth, and why embedment accuracy matters.…
Dust collection at the hole
The VACDRILL's dust collection port captures debris where it is produced, supporting silica-dust control.…
Why SDS, and how rotary hammers cut
How an SDS rotary hammer removes hard material, and why the VACDRILL accepts bits to 40 mm diameter and 200 mm length.…
The 20V cordless platform
The VACDRILL runs on a 20 V 6 Ah lithium-ion platform — powering both the vacuum pump and the rotary hammer.…
The seal, and what breaks it
The rubber sealing pad is the interface between the tool and the job. Everything about grip starts here.…
What 45 kgf of holding force actually means
Interpreting the VACDRILL's 45 kgf figure: what it is measured against and how to think about margin.…
Overhead drilling, mechanically
Why overhead drilling is the hardest case for a hand tool and the clearest case for a self-anchoring one.…
Hole accuracy and tolerance
Perpendicularity, diameter and depth — the three tolerances that decide whether a fixing performs.…
Vibration, fatigue and the operator
Hand-arm vibration and repetitive strain are occupational risks of hammer drilling. Removing the hand from the tool ch…
Attachment failure modes
How a vacuum attachment fails, what it looks like beforehand, and how to work so failure is not dangerous.…
Patents and intellectual property
The IP behind the VACDRILL: US 11,253,978 B1, design patent D968,485 S, and filings in China, Europe, Canada and Japan…
The vacuum pump
The pump is what makes the attachment active rather than passive — and what lets the tool work on imperfect surfaces.…
Design evolution of the VACDRILL
From R&D project sn49000 to the shipping VACDRILL and the VACDRILL Press — how the design developed.…
Vacuum anchoring versus magnetic drilling
Mag drills solved this problem for steel. Vacuum anchoring solves it for everything else.…
