It is intended for buyers who need a CIR50-system hammer for mining, quarry, water-well or construction drilling and who want the final hammer\/bit\/air configuration confirmed before order release.\u003c\/p\u003e\u003ch2\u003eProduct Positioning\u003c\/h2\u003e\u003cp\u003eCIR50 belongs to the low-pressure CIR DTH hammer family. Public exact-model references consistently identify the CIR50 bit-shank family and a 628 mm hammer length (less bit), and they use an F32×8 top-connection reference. Other dimensions and air-performance values vary between published CIR50 configurations, so PerfoMax controls the final supplied specification through the written quotation rather than mixing values from different variants.\u003c\/p\u003e\u003ch2\u003eConfirmed \/ Reference Information\u003c\/h2\u003e\u003ctable\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth\u003eItem\u003c\/th\u003e\n\u003cth\u003eCurrent controlled information\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eModel\u003c\/td\u003e\n\u003ctd\u003eCIR50\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct type\u003c\/td\u003e\n\u003ctd\u003eLow-pressure DTH hammer\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBit-shank family\u003c\/td\u003e\n\u003ctd\u003eCIR50\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eHammer length, less bit\u003c\/td\u003e\n\u003ctd\u003e628 mm common exact-model reference\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTop connection\u003c\/td\u003e\n\u003ctd\u003eF32×8 common exact-model reference; confirm supplied thread before ordering\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eExternal diameter \/ weight \/ hole range \/ air data\u003c\/td\u003e\n\u003ctd\u003eQuotation-controlled because public CIR50 model references differ by configuration\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\u003ch2\u003eApplications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eWater-well and general borehole drilling\u003c\/li\u003e\n\u003cli\u003eMining rock drilling\u003c\/li\u003e\n\u003cli\u003eQuarry drilling\u003c\/li\u003e\n\u003cli\u003eConstruction rock drilling\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eFinal suitability depends on rock condition, target hole size, matched bit, compressor capability and the exact supplied hammer configuration.\u003c\/p\u003e\u003ch2\u003eCompatibility \u0026amp; Ordering Checks\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eConfirm the required CIR50 bit-shank and mating geometry.\u003c\/li\u003e\n\u003cli\u003eConfirm the actual top-sub \/ drill-pipe connection; F32×8 is a common model-level reference, not a substitute for order confirmation.\u003c\/li\u003e\n\u003cli\u003eState target hole diameter and selected bit configuration.\u003c\/li\u003e\n\u003cli\u003eProvide available working pressure and compressor air delivery.\u003c\/li\u003e\n\u003cli\u003eState rock formation, drilling depth and operating environment.\u003c\/li\u003e\n\u003cli\u003eConfirm spare-parts, inspection, labeling and packing requirements.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eSupply Scope\u003c\/h2\u003e\u003cp\u003eStandard supply is the CIR50 low-pressure DTH hammer in the configuration approved in the written quotation.
