    Sandvik drill bit resharpening expansion: safety and productivity notes for mines

    Sandvik drill bit resharpening expansion: safety and productivity notes for mines

    First reported on International Mining – News

    30 Second Briefing

    Sandvik is adding the mid-range RG550Be drill bit resharpening machine to its portfolio, extending coverage across both top hammer (TH) and down-the-hole (DTH) drilling with a tiered line-up of high-end, mid-range and handheld units. The OEM is targeting improved safety and ergonomics in bit maintenance, moving more grinding work off manual benches and into enclosed, purpose-built machines. For mine operators, the broader range allows closer matching of resharpening capacity to fleet size and bit type, with potential gains in bit life and drilling penetration rates.

    Technical Brief

    • Machine design targets safe handling of heavier TH and DTH bits that exceed ergonomic manual limits.
    • Enclosure and guarding reduce operator exposure to grinding sparks, dust and rotating components.
    • Integrated coolant and dust extraction aim to control respirable dust and bit overheating during grinding.
    • Fixed grinding geometry supports consistent button profile restoration, reducing risk of bit failure in-hole.
    • Purpose-built controls and ergonomics are intended to minimise awkward postures and repetitive-strain injuries.
    • Moving resharpening from open benches into enclosed machines aligns with stricter site safety and hygiene regimes.
    • Wider adoption of such units could shift mine maintenance risk profiles from manual to engineered controls.

    Our Take

    Across recent Mining coverage, Sandvik appears repeatedly in product- and project-tagged items, signalling a push to control more of the drilling value chain from bits and resharpening through to full surface drill fleets, such as the AutoMine-ready rigs ordered for Vale Base Metals’ copper operations.

    The Tampere site expansion reported on 5 February 2026 suggests Sandvik is backing its rock drilling and crushing lines with added manufacturing and R&D capacity, which is likely where incremental drill bit and resharpening technology will be industrialised.

    Sandvik’s concurrent overhaul of global warranty processes and expansion of crushing and screening support in West Africa indicate a strategy of tying consumables like drill bits to stronger aftersales and service frameworks, which can lock in long-term fleet support contracts for contractors such as Redpath at Cowal gold operations.

    TerraLithium and BHE Renewables: geothermal lithium project lens for mine planners

    TerraLithium, an Occidental subsidiary, and BHE Renewables have produced lithium chloride from geothermal brines at BHE’s Calipatria geothermal plant in California’s Imperial Valley and converted it to battery-grade lithium carbonate. The partners have also directly converted lithium chloride to lithium hydroxide using a commercial-scale electrolyser at TerraLithium’s Brawley R&D facility in the US’s second-largest geothermal field, validating high-purity output against commercial processing standards. BHE Renewables plans to build, own and operate full-scale lithium production facilities in Imperial County once technical and economic feasibility is proven.

    Ground view Kazakhstan at Qarmet mines: safety, control and data lessons for engineers

    Kazakh steel and mining company Qarmet has installed an almost total underground visibility system at its eight former ArcelorMittal coal mines in Karaganda, combining helmet‑mounted cameras with live location tracking of every miner on a central control‑room schematic. Pre‑shift “health booths” at the portal process about 50 workers per hour, checking blood pressure, pulse, eye fatigue and alcohol, with roughly 1% barred from descending, and all footage stored on 1 TB helmet units and uploaded after each shift. The in‑house system, developed by teams of about 30 per mine, is paired with a privately funded medical centre delivering around 200 check‑ups a day, but raises unresolved questions about consent and long‑term use of pervasive surveillance in a company town setting.

    Gladiator–BlackRock Yukon raise: drilling scale-up and project lens for mine planners

    Gladiator Metals has raised over C$35 million in a BlackRock-led private placement, issuing 7 million flow-through shares at C$3.87 and 3 million non-flow-through shares at C$2.65, lifting its treasury to about C$50 million and its market capitalisation to C$357.9 million. The funding fully covers the 2026–2027 drilling campaign at the Whitehorse Copper project in Yukon, targeting multiple high-grade prospects across a 35 x 5 km belt. Cowley Park, with more than 300 historical holes and 700 m of defined copper-molybdenum strike, will see drill capacity doubled from three to six rigs by late summer.
