SPM top hammer drill bits are specially designed for hard to very hard and highly abrasive rock formations. The tophammer drilling tools present a fast penetration as well as long service life.
Applications
1. The drill bits are widely used for guide rail type pneumatic rock drilling machinery and hydraulic drill carriages.
2. They are excellent button bits, suitable for drilling anchorage holes for underground mining, blast holes and shaft of mines.
3. The mining drill bits are also an ideal choice for roadway construction, blast holes and anchorage holes drilling applications in large sized underground metal mines.
4. They are commonly found in the construction and excavation sites of railway, highway tunnel, diversion tunnel in hydropower projects and underground workshops.
