8-inch
Max Wet & Dry Drilling: Adapts up to 8-inch drill bits. Our standup core drilling machine with stand can perform wet and dry two modes drilling, and you can feel assured of accuracy when boring holes in a variety of surfaces with a 8 in / 20 cm diameter hole capacity.
Attention: a industrial-grade 4.25 in core bit is only included.
Capable Coring Efficiency: A 2500W powerful motor and 750RPM high-speed gearbox are intentionally taken to complete diversified drilling projects, allowing the operator to adjust based on the specific material being drilled.
Max Drilling Depth: 23.62 in / 60 cm.
Output Arbor Sizes: External Thread 1-1/4" x 7 UNC, Internal Thread 5/8" x 11 UNC.
Expertly Designed for Security: Our diamond core drill rig integrates a secure clutch with an overload protection device to work by automatically tripping when the drill bit becomes stuck or encounters resistance beyond a certain level, further reducing the risk of operator damage and injury during the operations.
Effortless Drilling: Our concrete core drill has a rustproof steel forged output shaft to bear more pressure, an upgraded one-touch water pipe connector for a stable water supply, and a thickened guide rail to stabilize the machine and reduce shaking.
