Product Description
Construction Re531 Reverse Circulation Hammers - Easy Operation Flame Retardant
Advantages: R.C. Drilling, referred to as "Centre Sample Recovery" or "Dual Wall Drilling", employs a Dual Wall Pipe where the drilling medium (normally high pressure air) is passed between the outer and inner tubes down to the face of drilling bit where it is returned up the centre tube along with the sample cut by the drill bit.
- No contamination: The R.C. System collects samples through recovery holes in the drill bit face immediately as cuttings are formed, preventing sample loss and contamination during travel through the hammer.
- Higher Production: In broken and fractured ground conditions, the R.C. system often outperforms conventional hammers in penetration rates.
- Dry Sample: Even in water-bearing strata, dry samples can often be collected as cuttings are captured immediately through the drill bit face.
- Higher Sample Recovery: With samples collected through the bit face and proper bit-to-chuck matching, recovery rates up to 98% are achievable with minimal sample bypass.
