Carbide Tipped Reamers from Infinity Tool MFG include DTH Hole Openers, Tricone Hole Openers, and PDC Reamers engineered to enlarge boreholes across oil & gas, mining, geothermal, water well, and construction drilling. Built with tungsten carbide buttons, tricone rollers, and PDC cutters, these tools deliver durable, symmetrical hole cutting in hard and soft rock formations.






DTH hole openers use tungsten carbide buttons driven by a down-the-hole hammer for hard rock formations, tricone hole openers use rotating carbide-tipped roller cones for versatile soft-to-hard formation drilling, and PDC reamers use polycrystalline diamond compact cutters for hole enlargement and stabilization in hard rock. Each is suited to specific formation types and drilling methods.
