Underground production and long hole drilling

The difference between a guide tube and a guide rod is the level of hole straightness needed at the quarry or mine.
Where there are challenging rock formations with a higher liability of hole deviation, a guide tube is the best solution.

T51 Drill bits

Please note: that all button bits are manufactured over-sized 0,5-2,5 mm (it depends on the size of bit and buttons), meaning that for example a 45,0 mm bit is at least 45,5 mm.
as new, or the size of a 140,0 mm new bit can be 141,5 mm to 142,5 mm (it depends on the model and type of bit). This is done because of the fast initial wear on button bits. It is important to consider that the drilled hole could vary in size due to drilling conditions, drilling practices and ground formation.
