Product Description

Product Introduction
Top hammer drilling tools can be applied in such as surface civil engineering, quarrying, dimensional stone quarrying, underground mine development, rock bolting, tunneling and production drilling.

SOLLROC stocks a comprehensive supply of Tophammer Drilling Tools. Whether you require bits, coupling sleeves, shank adaptors or rods, we have exactly what you need when you need it.

Top hammer drilling principle
1. When the piston hits the shank, kinetic energy in the piston creates a compressive wave in the string of drilling tools, that will cause the bit to penetrate the rock
2. Piston velocity at impact ≈ 10m/s but the compressive wave in the drill steel travels at a velocity of 5180 m/s (velocity of sound in steel)
3. The bit is forced forward and penetrates the rock around 1.0 mm
4. Part of the energy not used to penetrate the rock goes back as a tensile wave and part of it as a compressive wave
