Knowledge base

Longer-form background on the industry the tool sits in: the regulations that shaped it, the fixings it serves, and the physics it depends on.

GRABO VACDRILL self-anchoring drilling system product flyer

Respirable crystalline silica: the rules that changed drilling

Silica is the reason dust extraction stopped being optional.

Engineered stone and the silicosis crisis

The most dangerous dust in the trade comes from the nicest-looking material.

Embedment depth and why anchors fail

Anchors do not fail because they are weak. They fail because the hole was wrong.

Mechanical versus adhesive anchors

Expansion anchors forgive a rough hole. Adhesives do not.

A short history of vacuum lifting

The idea is old. Making it portable and powered is recent.

Modern electric vacuum grippers, or gripsters

A suction cup holds a smooth pane. A powered gripster holds almost everything else.

Atmospheric pressure, altitude and vacuum tools

At altitude there is simply less atmosphere to push with.

Hand-arm vibration and power tools

The damage is permanent, and the exposure is measurable.

Overhead work and musculoskeletal injury

The shoulder is not designed to hold a hammer drill above your head all day.

Rotary hammer versus hammer drill

One delivers impact energy. The other just vibrates.

SDS, SDS-plus and SDS-max explained

Three names, two of which are sizes.

Post-installed rebar connections

This is structural concrete design executed with a drill.

Dust extractor classes and filters

The wrong extractor recirculates exactly the fraction that harms you.

Scanning before you drill

The expensive mistakes are all invisible from the surface.

Concrete strength, aggregate and drillability

The aggregate decides, more than the grade does.

Tool identification and site security

An unrecorded tool is an unrecoverable tool.

How to choose a drilling system

Four questions decide it.

Total cost of ownership for specialist tools

Rework and downtime cost more than the tool.

Standards, approvals and CE/UKCA marking

A mark is a declaration of conformity, not a performance rating.

The real productivity of anchor installation

Fast holes that fail inspection are not fast.

GRABO's vacuum technology lineage

The drill is the lifter's technology, pointed at a different problem.
