Sandvik has introduced the mid-range RG550Be, expanding its drill bit resharpening machine portfolio.
The range now covers all operational needs for top hammer (TH) and down-the-hole (DTH) drilling, with high-end, mid-range, and handheld machines designed for safety, ergonomics and performance.
The company said recent field tests indicated that scheduled resharpening can extend the life of a drill bit by up to ten times and reduce the cost per drilled meter by 43 per cent or more.
The range includes the RG600Pro, RG550Be and RG500Hh.
The RG600Pro is a high-end, semi-automatic, stationary machine for TH and DTH bits (up to 180 mm skirt/shank diameter), featuring multi-bit loading, adaptive programming, water filtration, ventilation, Wi-Fi connectivity and digital dashboards. It remains Sandvik’s flagship solution for high-volume operations.
While the RG500Hh is a handheld, pneumatic, high-powered grinder for all bit sizes, ideal for on-rig or smaller operations.
Both RG600Pro and RG550Be offer 24/7 access to performance data, machine monitoring, digital spare parts lists and RFID-enabled grinding cup compatibility.
“Our innovative equipment together with good resharpening routines improve quality, capacity, and cost efficiency while reducing CO₂ emissions and product waste,” Kota said.
