General description
hole openers have a range of cutting structures and hydraulics to suit any application where hole enlargement is needed without drift diameter issues.
The body design permits use of substantially larger bearings on each of the individual cones for added durability while the body itself is manufactured from a solid billet of AISI 4145 heat treated steel, inspected to DS1/NS1 and NS2 for rental equipment.
The cutter ensures optimum penetration, long life and exceptionally smooth running as a result of our random cutter design and cone offset angle technology – developed over many years by the bits industry.
An optimised body to hole size allows high annual velocities to be achieved alongside the hole opener body, permitting much better hole cleaning than any existing designs. Cleaning is supported by three jets which remove cuttings and reduce the need for re-cutting.
New diamond impregnated gauge protection helps prevent tools from going under gauge and possibly loosing cones. This also contributes to reduced vibration, smoother running and ultimately delivers a truer hole shape, eliminating unwanted ledges and other defects in the hole.
