G129 Diamond Wire at the Angola Black Granite Quarry 01
Angola Quarry

G129 Diamond Wire at the Angola Black Granite Quarry

Quarry bench cutting — hard black granite

Application
Granite quarry bench cutting and block squaring in Angola Black granite, a hard and abrasive stone that punishes both the bead bond and the wire assembly.
Challenge
The quarry needed higher output per shift without accepting wire breakage or the downtime that comes with it. In abrasive granite the usual trade-off is aggressive cutting versus wire life — you rarely get both from a standard bead.
Material
Angola Black granite — hard, abrasive
Equipment
55kW wire saw machine, operated on a standard bench cutting layout.
Diamond Tool
G129 diamond wire — optimized diamond concentration and distribution, advanced alloy bead bonding, reinforced wire assembly.
Working Conditions
Continuous quarry production, bench cutting with block squaring on the same wire.
Result
Cutting speed 8–10 m²/hour. Wire lifetime 20–24 m² per meter. Stable cutting with no wire breaks recorded, and measurably reduced downtime.

16 Years, 18 Wire Saws — Dolomite & Marble Quarry 02
Namibia Quarry

16 Years, 18 Wire Saws — Dolomite & Marble Quarry

White dolomite block production — a 16-year partnership

Application
White dolomite and marble block production in a remote quarry, running a fleet of wire saw machines continuously across a long production calendar.
Challenge
A remote site in a harsh environment, where a machine failure is not a phone call away from a spare part. The requirement was uptime above everything else, sustained over many years — not the lowest price per unit.
Material
White dolomite and marble
Equipment
18 × 55kW wire saw machines, all still operating in the quarry today, including the very first machine supplied.
Diamond Tool
M002B diamond wire, supplied continuously across the full 16-year relationship.
Working Conditions
Remote quarry, harsh environment, continuous multi-machine operation over 16 years.
Result
All 18 wire saw machines still in service, including the original unit. A partnership that has run from the early Keentool days through to the current KEENOVA generation.

Granite Block Production — South Africa 03
South Africa Quarry

Granite Block Production — South Africa

Abrasive granite, uptime-led operation

Application
Granite block production from an abrasive South African granite deposit, running on a production schedule where machine availability sets the output ceiling.
Challenge
Abrasive granite wears tooling quickly, and the quarry could not absorb repeated stoppages. Wire life had to hold up across long production runs rather than peak on a single test cut.
Material
Abrasive South African granite
Equipment
55kW wire saw machine.
Diamond Tool
W789 diamond wire, specified for the abrasive granite conditions on site.
Working Conditions
Continuous block production, abrasive granite, uptime treated as the primary commercial metric.
Result
Higher output per shift, with wire life stable enough to plan production around rather than react to.

South Africa Quarry

DTH Drilling at Impala Granite Quarry

Quarry development drilling

Application
Blast-hole and quarry development drilling at Impala Granite Quarry, where drilling performance sets the pace for everything that follows.
Challenge
Hard granite drilling where penetration rate and hole straightness both matter — a slow or wandering hole pushes the whole development program back.
Material
Impala granite
Equipment
KEENOVA DTH drilling machine, with pneumatic DTH drilling also deployed at the same granite quarry for comparison.
Diamond Tool
Not applicable — this is a drilling application. Down-the-hole hammers and bits are the consumable set here.

Gold Reef Cutting Underground — South Africa 05
South Africa Mining

Gold Reef Cutting Underground — South Africa

Confined underground stopes, low light, dust

Application
Gold reef cutting underground in a South African mine — a confined stope environment where the cutting system has to work in dust, poor light and limited space.
Challenge
Underground conditions are the hardest case for any wire saw system: restricted access for setup, no room for a large machine, and an operator who cannot easily see or reach the cut. Reliability under those conditions is the whole requirement.
Material
Gold-bearing reef (quartzite)
Equipment
55kW wire saw machine, configured for underground deployment.
Diamond Tool
M002B diamond wire.
Working Conditions
Underground gold mine, confined stope, low light, airborne dust, limited access.
Result
The system cut gold reef successfully underground — a case most suppliers of quarry equipment cannot support, and one that demonstrates the range of the wire saw platform.

Wire Saw Machine at Rustenburg Quarry

Reference installation, South Africa

Application
Block extraction at Rustenburg Quarry, South Africa, using a 55kW wire saw machine as the primary cutting unit.
Challenge
Establishing a dependable, repeatable cutting cycle at the quarry — the machine had to hold cut quality across a full production schedule, not just a demonstration run.
Material
Granite
Equipment
55kW wire saw machine, the same platform widely deployed across Southern African quarries.
Diamond Tool
Diamond wire specified to the quarry's stone and machine power.
Working Conditions
Active quarry bench, continuous block production.
Result
The machine was documented working in continuous quarry production, and the installation became a reference site for the 55kW platform in South Africa.

Bridge Structural Cutting — Sweden 07
Sweden Construction

Bridge Structural Cutting — Sweden

Heavily reinforced concrete spans

Application
Structural cutting on a bridge in Sweden, where the cut has to be made cleanly through heavily reinforced concrete spans.
Challenge
Dense reinforcement makes this a job a blade cannot do. The cut had to pass through concrete and rebar in a single operation, with the precision a structural modification demands — and without weakening the remaining structure.
Material
Heavily reinforced concrete
Equipment
Wire saw system, set up on the structure for controlled structural cutting.
Diamond Tool
G635B diamond wire — concrete wire specified for reinforced sections.
Working Conditions
Bridge deck and span cutting, heavy reinforcement, structural tolerance requirements.
Result
Clean, precise structural cuts through reinforced concrete spans, with the structure released for the next phase of works.

Steel Furnace Cutting — Baosteel Plant 08
Baosteel Plant, China Industrial

Steel Furnace Cutting — Baosteel Plant

4-meter-diameter furnace, cold cutting

Application
Dismantling a 4-meter-diameter steel furnace at the Baosteel plant. This is outside the usual quarry and construction scope — it is heavy industrial demolition, and it is a genuine test of what diamond wire can do.
Challenge
Thick cast steel, and hot cutting was not permitted on site for safety and shutdown reasons. That ruled out torches and thermal methods entirely, leaving very few options for a section this size.
Material
Steel furnace shell — solid steel
Equipment
75kW wire saw machine, the highest-power platform in the range, required for the section thickness involved.
Diamond Tool
ST11 diamond wire, and on a related plant job vacuum-brazed diamond wire was used to cut a large solid steel block.
Working Conditions
Operating steel plant, safety-critical environment, cold-cutting method mandatory.
Result
Cold, precise and safe dismantling of a 4-meter-diameter steel furnace, meeting the plant's safety and shutdown requirements without any thermal cutting.

Cutting a Reinforced Concrete Block with Diamond Wire 09
Engineering Validation Construction

Cutting a Reinforced Concrete Block with Diamond Wire

Documented cutting test — reinforced concrete

Application
Cutting a reinforced concrete block as a controlled demonstration of high-performance diamond wire on reinforced concrete.
Challenge
Reinforced concrete cutting is where wire selection most often goes wrong — the wire has to handle the abrasive concrete and the steel reinforcement in the same pass, and a poorly matched bond fails early.
Material
Reinforced concrete
Equipment
Wire saw system, set up specifically for the reinforced concrete test cut.
Diamond Tool
High-performance diamond wire for concrete — the same specification family used on the structural cutting projects.
Working Conditions
Documented test cut, reinforced concrete block, controlled setup.
Result
The reinforced concrete block was cut cleanly, and the run was documented on video as the reference demonstration for concrete wire selection.

Tungsten-Free Diamond Beads at Carrara Marble 10
Carrara, Italy Quarry

Tungsten-Free Diamond Beads at Carrara Marble

KB105 bead development — white marble

Application
White marble quarrying at Carrara, where the balance between cut quality and tool cost is unusually tight because the stone is high value and unforgiving.
Challenge
Conventional bead formulations were pushing cost per square meter up, and tungsten supply risk made the bond chemistry an exposure in itself. The quarry needed efficiency without depending on tungsten.
Material
Carrara white marble
Equipment
Existing quarry wire saw setup at the partner operation, used for the field trial.
Diamond Tool
KB105 diamond beads — cobalt- and tungsten-free bond technology, a newly developed design at the time of the trial.
Working Conditions
Real quarry operating conditions in Carrara white marble, continuous production, field performance measured over the trial period.
Result
Cutting speed 20–22 m²/hour, wire life 50–60 m² per meter. Balanced cutting behavior, and — the commercial point — improved cost control without relying on tungsten.

Long-Term Diamond Tools Supply — Canada 11
Canada Supply

Long-Term Diamond Tools Supply — Canada

Consistency across a multi-year partnership

Application
Ongoing diamond tools supply to a long-standing Canadian partner, covering the full tools range rather than a single product line.
Challenge
In diamond tools, the hard part is not the first order — it is the tenth. Batch-to-batch consistency is what protects the customer's process, because a tool that behaves differently each shipment forces them to re-tune everything downstream.
Equipment
Not applicable — this is a consumables and tools supply relationship, not a machine installation.
Diamond Tool
Diamond wire, cutting tools and grinding and polishing tools supplied as a coordinated range.
Working Conditions
Multi-year supply relationship, repeat orders across the full tools range.
Result
A sustained partnership built on consistency rather than price — repeat supply across wire, cutting tools and grinding and polishing consumables.

20-Foot Container: Machinery, Wire & Consumables 12
Global Supply Supply

20-Foot Container: Machinery, Wire & Consumables

Mixed consignment, consolidated and inspected

Application
A complete quarrying equipment shipment combining wire saw machinery, diamond wire, drilling tools and quarry consumables in one 20-foot container.
Challenge
Mixed consignments are where procurement complexity concentrates. Sourcing the items is the easy part — the risk sits in inspection, packaging, weight distribution and securing, and in getting several suppliers to converge on one shipment date.
Equipment
Wire saw machinery and drilling tools, loaded alongside the consumables.
Diamond Tool
Diamond wire and quarry consumables consolidated into the same container.
Working Conditions
Pre-shipment inspection, packaging and protection, container loading and securing, with space optimization against safe weight distribution.
Result
One consolidated shipment, inspected before loading and secured for transit — collapsing a multi-supplier procurement into a single delivery for the customer.
