Robit drills further and faster
FOUNDED in 1985 and headquartered in Finland, Robit manufactures, sells and services a wide range of quality drilling consumables for the mining, construction, and water well industries around the world.
With manufacturing facilities in Finland, Australia, South Korea and the UK, Robit is an international company with active sales networks in 115 countries.
In serving the global mining industry, Robit offers a comprehensive range of top hammer and down- the- hole drilling consumables for both surface and underground applications.
Robit’s focus is on driving value through productivity.
This is reflected in the design and quality of all Robit products, but probably best demonstrated in Robit’s innovative, next- generation drill bit designs which help drilling consumable performance keep pace with increasingly productive, automated drill rigs.
Robit Evolution bit series
The Evolution bit series is the result of a systematic approach towards crafting the world’s best button bits.
After extensive world-wide testing, the Evolution series has proved itself with improved rates of penetration and wear life – with bit life increasing by 20pc and button sharpening intervals increasing by as much as 60pc.
Robit Evolution bits come with features unique to Robit, and the heart of the bit design is in the unique head design with optimised flushing characteristics.
The Evolution technology is offered throughout the bit range, from 45mm upwards.
Robit Diamond Button series
Automation in mining is here and the trend towards remote drilling is increasing at pace.
The drivers for this are productivity and safety. Autonomous drilling removes the risk of constant manpower in hazardous, harsh environments, and opens up opportunities for multi-rig, single-operator drilling.
The challenge for autonomous drilling however is the need to change drill bits frequently.
Standard bits might last 50-80 drill metres before they need sharpening, but each production cycle might require 250-400m of drilling.
Every bit change pauses the production cycle – moreover, it places personnel in harm’s way.
Robit’s new Diamond Button bits enable continuous remote drilling of the production cycle without loss of hole diameter.
Actual drilling time per shift is significantly increased while reducing personnel exposure to working areas, thus increasing total production and improving safety.
Costly and hazardous bit sharpening operations can be eliminated or reduced.
Fewer bit changes also means a reduction in the total number of bits needed in the drilling circuit and stores, with an associated reduction in manual handling and total supply chain burden.
