Concrete auger, 22 x 800 mm, SDS PLUS MATRIX
Categories: Concrete augers
The hard-face plate of VK8 grade is specially sharpened. It is designed for impact drilling. The tool is made of steel, grade 40H. The bit with bilifar helix allows to improve removal of drilling waste and reduces load on the perforating gun. The body of the bit has increased cross-sectional area which reduces amplitude of its vibrations. When working with the bits exceeding 400 mm additional predrilling with shorter bit is necessary. The shank needs lubrication.
