Sandvik drill bit resharpening expansion: safety and productivity notes for mines
Reviewed by Joe Ashwell

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.
