Reliable drilling tools for hand-held and hydraulic rock drills
Rock drilling steels and button bits for hand-held pneumatic rock drills and hydraulic rock drilling machines used in quarrying, construction and hard-rock drilling. Drilling steels are supplied in a range of shank types, lengths, diameters and thread configurations, and button bits in different button shapes and face configurations, so the set can be matched to the machine, the rock formation and the hole requirement.
The steel transfers impact energy from the machine to the bit while keeping the hole straight. Integral drill steel, tapered drill steel and threaded drill rods are available in different shank configurations, lengths and diameters. Select the steel against the drilling machine, shank type, hole diameter, drilling depth and rock conditions.
Spherical button bits suit demanding, abrasive rock; ballistic button bits are designed for efficient penetration in suitable formations. Button layout and face design are chosen against rock hardness, abrasiveness, drilling stability and flushing requirements.
Drilling performance depends on the combination of machine, drilling steel, button bit, hole diameter and rock formation, so we work from your drilling machine model and existing steel and bit dimensions rather than from a catalog entry.
Values we can state from real applications, with the basis for each one.
Every specification above is confirmed against your material, machine and site conditions before an order is placed.
We specify against the job rather than the catalog. These are the facts that decide the answer for anything in Quarry Equipment.
This product is specified as part of a set. These are the wire families and product groups it is normally combined with — final selection depends on the material, the machine and the site conditions.
Actual applications with the equipment, tooling and working conditions recorded.
DTH drilling demonstrated working performance on Impala granite in continuous quarry conditions, supporting the quarry development program.
The machine was documented working in continuous quarry production, and the installation became a reference site for the 55kW platform in South Africa
Higher output per shift, with wire life stable enough to plan production around rather than react to.
How this equipment and tooling performs in real quarry and construction conditions.
Send the material, the machine and the working conditions. We will come back with a specification that suits the job — and say plainly where a limit exists.
