Mole with handle and bar1Very robust model with specially hardened forgeddrill bits. For determining soil properties, moistureand structure. The shape of the Mole‘s drill bits ensuresminimum friction when drilling and removingthe Mole from the ground. This reduces physical effortto a minimum.The Mole has different components. Handle with 75cm rod, extension rod 100 cm if necessary and one ofseven available drill bits, each of which is designedfor a particular soil type. The components can be combinedwithout any problems. Extension rods can extendthe working depth of the Mole down to 5 m.Please order drill bits seperately!23Drill bits for moleThere are various drill bits for Mole, which are each designed for very specific soilproperties:Clay and damp soilWith narrow side panels for minimum soil friction/resistance. As wet soils areusually very cohesive, the soil still adheres to the bit very well.SandWith broad side panels and therefore a large retention capacity for the sand.Coarse sandWith extra broad side panels enclosing even more of the bit so that even coarsesandy soils and very dry soils are retained.CombinationRetains both strongly cohesive and less cohesive soils.RiversideVery suitable for drilling in hard, encrusted soils and soils mixed with fine gravel.The drill cutters project from the drill itself, so that friction is greatly reduced.Gravel drillWith slightly rounded, oblique scoops which pull themselves downward in thegravel. Any stones present are clamped between the drill sides. Finer soil material(coarse sand with fine gravel) is retained in the drill bit.Stone catcherThe stone catcher is used to collect and remove stones that prevent proper samplingwith one of the other drill bits.A B C D E F GMole with handle and barModel Length cm Price € Item no.1 handle with rod, 75 134,60 5350-1005 N4without drill bitAccessoriesDescription Price € Item no.2 Extension for mole 65,70 5350-1010 N4Transport case L x W 121 x 22,5 cm 83,00 3600-2120 N4Drill bits for moleModel Price € Quantity scale from Scale price € Item no.A clay and wet soils 092,60 5 087,20 5350-1015 N4B sand 110,90 5 105,70 5350-1020 N4C coarse sand 161,30 5 149,80 5350-1025 N4D combination 105,50 5 099,10 5350-1030 N4E riverside 110,90 5 105,50 5350-1035 N4F gravel drill 135,90 5 130,20 5350-1040 N4G stone catcher 121,70 5 116,30 5350-1045 N4137
