Core drilling rigs can be inverted. Vertical diamond drilling rigs inherently support vertically downward core extraction; the base must be securely locked to the floor using high-strength expansion bolts to prevent the equipment from loosening or falling during drilling. 300mm large-diameter drilling rigs have high weight and torque, requiring strict verification of their fixing strength. When inverted, cooling water will flow upwards; therefore, proper water diversion and waterproofing measure

The drilling rig was supplied with a 127mm diameter drill bit; the core sample needs to be obtained by tapping the drill bit.

This coring drill cannot use 14-inch drill bits. The drill can support holes with a maximum diameter of 300mm.

What does the housing refer to? The drill does not include a toolbox, comes with a stand, and includes a 127mm diameter drill bit. If this answer does not resolve your current issue, please contact us again for assistance.
