Who is the STR tool suitable for?

The set is aimed at plasterers and ETICS specialists who regularly countersink screw anchors such as the EJOT STR U 2G .

Your advantage with recessed mounting

The adjustment mechanism quickly sets the tool to the respective dowel length, and the setting control according to the STR principle indicates secure anchoring.

Choosing the right bit and cutting plate

The bit and cutting plate must match the dowel type and the insulation thickness.

Bits for STR U 2G and STR H

The STR U 2G and STR U have a TX30 drive, the STR H a TX25 drive; according to specialist retailers, the set includes bits for both dowel types.

Cutting plates and tool type

According to specialist retailers, the set includes one long and one short cutting blade. Depending on the tool type, the type approvals require a minimum insulation thickness of 80 mm (Type S) or 100 mm (Type L); the specific requirements are indicated in the installation instructions.

Notes and limitations
