H19 (3/4) INTEGRAL DRILL STEELS
Integral drill steels are commonly used in underground mining and small-hole drilling operations. They are often paired with low-power rock drills, such as air-leg or hand-held rock drills. The integrated design helps to reduce the loss of impact energy, thereby improving the speed and efficiency of rock drilling.
The specifications for H19 (3/4) integral drill steels typically include details such as the shank size, length, bit diameter, and weight. These tools are available in various lengths and bit diameters to suit different drilling requirements. The use of high-quality materials and advanced manufacturing techniques ensures their durability and performance in demanding drilling conditions.

BIT DIAMETER NOTES
All bit diameters are larger than the given dimensions in the catalog.
Cross bits: Can be a maximum of +1 mm due to manufacturing tolerance.
Button bits: Some bit designs can be a maximum +3 mm to compensate for fast diameter wear.
The minimum diameter for all button bits is +1.5 mm above the given dimensions.
Keep in mind that a bit always drills a bigger hole than the stated bit diameter.
