First digit, it’s the series.
1,2 and 3 designate STEEL TOOTH BITS with 1 for soft, 2 for medium and 3 for hard formations.
4,5,6,7 and 8 designate TUNGSTEN CARBIDE INSERT BITS for varying formation hardness with 4 being the softest and
8 the hardest.
Steel tooth bits adapt to soft
formations with low
compressive strenth and high
drillability.
Tungsten carbide insert bits
adapt to soft formations with
low compressive strenth and
high drillability
Second digit, it’s the type.
1,2,3 and 4 are further breakdown of formation with 1 being the softest and 4 the hardest=
Tricone for very soft formation
Tricone for medium hard
formation
Third digit, it’s the bearing/seal type.

Nous disposons d’une large gamme d’outils neufs ou reconditionnés. Les outils reconditionnés, sont
des outils en fin de vie pour le forage pétrolier mais encore utilisables pour le forage d’eau.
