Sandvik RG550Be drill bit resharpening: utilisation and maintenance notes for mines
Reviewed by Joe Ashwell

First reported on Australian Mining
30 Second Briefing
Sandvik has launched the mid-range RG550Be drill bit resharpening machine, extending its RG-series portfolio between the smaller RG420 and the high-capacity RG600Pro to cover a broader spread of rotary and DTH bit sizes. The RG550Be targets mines seeking in-house bit maintenance where full automation is not yet justified, offering programmable grinding cycles and standard Sandvik bit geometry profiles to maintain penetration rates and reduce bit replacement frequency. For operations engineers, the expanded range allows closer matching of machine capacity to fleet size and bit diameter, improving utilisation of workshop grinding assets.
Technical Brief
- RG550Be is configured for both rotary and down-the-hole (DTH) drill bit geometries.
- Machine design allows resharpening of button bits with complex, multi-facet carbide profiles.
- Programmable grinding cycles are intended to standardise bit profile restoration across different operators and shifts.
- Mid-range capacity targets workshops where manual grinding is still common but quality control is problematic.
- For fleet planners, closer matching of machine size to bit inventory can reduce idle grinding capacity.
- Wider RG-series coverage supports centralised regional workshops servicing multiple pits or satellite operations.
Our Take
In our database of 970 mining stories, Sandvik features frequently in equipment and Product-tagged pieces, and the Tampere expansion reported on 5 February 2026 suggests the company is backing its drill bit resharpening line with added manufacturing and R&D capacity rather than treating it as a niche add-on.
The new resharpening machine sits alongside Sandvik’s recent overhaul of global warranty processes (21 January 2026), which likely makes it easier for Australian mines to integrate bit maintenance into standardised service contracts and fleet support arrangements.
For Australian operators already using Sandvik underground fleets at sites like Evolution Mining’s Cowal Gold Operations (22 January 2026), an expanded drill bit resharpening portfolio can tighten the link between consumables performance and OEM equipment orders, strengthening Sandvik’s position in lifecycle supply negotiations.
