Larger piston and bore than the 4-inch CIR90 for higher impact energy at 18-25 bar. 5-inch class splined drive with field-serviceable split-ring bit retention. Valve-less distributor design recovers expansion energy for efficient deep-hole performance.\u003c\/p\u003e\u003ch2\u003eApplications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eLarge-scale open-pit mining: production blast holes 120-165 mm\u003c\/li\u003e\n\u003cli\u003eQuarrying: deep large-diameter production drilling\u003c\/li\u003e\n\u003cli\u003eWater well: large-diameter boreholes in consolidated rock\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eKey Differences from CIR90\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e5-inch class vs 4-inch — larger piston, higher impact, larger bit shank\u003c\/li\u003e\n\u003cli\u003e120-165 mm hole range vs 105-130 mm\u003c\/li\u003e\n\u003cli\u003eRequires larger compressor: 25 m3\/min vs 15-18 m3\/min\u003c\/li\u003e\n\u003cli\u003eAPI 2-7\/8 or 3-1\/2 Reg top sub vs 2-3\/8 Reg\u003c\/li\u003e\n\u003cli\u003eBit shank NOT interchangeable with CIR90\/DHD340\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eRequest a Quotation\u003c\/h2\u003e\u003cp\u003eProvide your rock formation, hole diameter\/depth, rig model, and compressor capacity.
