Two Wing Type - Coal Auger
Two Wing Type - "Coal Auger"
General Features
38mm drill bit diameter.
Robust two wing drill bit for dry drilling larger diameter holes in soft to medium conditions.
The positive front rake assists in penetration with low thrust machines while the concentric tips minimize drill rod wander.
These drill bits have been designed for dry drilling in conjunction with scroll type drill rods. The bits have a round shank and a shoulder drive.
The grade of tungsten carbide insert provides extremely good wear resistance and is time proven for all types of conditions.
The drill bit body is made of high tensile material for strength and abrasion resistance.
Packaging
Supplied in cardboard boxes of 50 or plastic pails containing 20 drill bits.
