SS--DH (Soft Drill DH (Soft Drill HeadHead))

For very soft uo to medium soilsØ 80 mm with steering plates W x L (mm): 85 x 135/175 or 205, 110 x 175Ø 120 mm (for Grundodrill 20 S): B x L (mm): 120 x 200/240 Special plates Bore head also without steering plates with hard metal bits


MM--DH (Medium Drill DH (Medium Drill HeadHead))

for medium to heavy homegeneous soils, Ø 100 or 140 mmChisel geometry specially tuned to the percussive hammer Large bore canal – good reflux Very easy to steer extra-stable, exchangeable round-framed chisel Fitted with hard metal bits


for medium up to heavy fissured and loosesoils Ø 80 or 120 mm oval cylindrical form with compact fitting of hard metal bits for optimal open-cutting

Backreamer with Backreamer with roundround--framed chiselframed chisel

Conical form for calm run and optimal smoothness of bore canalVarious sets for various soil conditionsAlso with flow groove for better transportation of the bore spoilsSuitable for almost all soil types


Push headPush head

For an easy push into the bore canal after an intermediate clearanceNo need for screwing on and redrawing of the drill rodsNo jamming inside the bore canal, immense time saving


QuickQuick--ConnectorConnector

Quick-Connector

Break-away tool

Quick connection-plug connection with non-return valve as protection againstpenetration of soil particlesFor a quick and easy connection and break-away of bore tools from drill rods Extensive loosening with heavy pipe wrenches etc. is not necessary


GRUNDODRILL X SERIESGRUNDODRILL X SERIESTwinTwin Drive drill Drive drill rodsrods

Less danger of breakages, withstands high strains

Specially heat-treated

Up to 40% longer service life

No dirt penetration

Low wear of the threadings

High Bentonite flow rate

Up to 40% less torque required for loosening the drill rods


PipePipe--pullerpuller for PE/PPfor PE/PP--pipes frompipes from OØ 50 mmOØ 50 mm

Pipe-puller with sealStandard pipe-puller

Pipe-pullers are applied for pulling in pipes and form a connection between swiveland the PE product pipe to be installed. Pre-equipped in series for the tensile strength measuring device Grundolog


Cutting nipplesCutting nipples for PE/PPfor PE/PP--pipes frompipes from OØ 50 mmOØ 50 mm

Cutting nipples form a connection between the swivel and the Pe-product pipe to be installed. They are screwed into the pipe. Pre-equipped in series for the tensile strength measuring device Grundolog
