Concrete coring is already a task that requires precision, but when the hole needs to be cut at an angle, the difficulty increases significantly.
We often get requests for angled openings, whether for M&E services, retrofitting works, or specialist installations, and clients are sometimes surprised at the extra planning and care that’s needed.
So why is angled coring more challenging than vertical or horizontal cuts?
Drill Stability
When drilling vertically, gravity helps to keep the drill stable. At an angle, the machine must be fixed securely with a drill stand to prevent vibration or movement. Even a small slip can lead to an inaccurate hole or damage to the surrounding structure.
Proper Technique Matters
Angled coring needs a combination of skill and patience. Our operators usually begin with a reduced feed rate until the bit is fully engaged, then gradually increase the pressure to complete the cut efficiently. Without proper technique, the risk of cracks, inaccurate holes, or equipment damage increases.
Initial Engagement
Starting the cut is one of the trickiest parts. A core bit entering at an angle doesn’t naturally sit flat against the surface, so it requires a slower feed rate at the beginning. This prevents the bit from skidding across the surface or chipping the entry point.
Wear and Tear
The angled approach places more uneven forces on both the drill bit and the coring rig. Over time, this can cause faster wear on the diamond segments, the motor, and the bearings; making angled coring tougher on equipment compared to straight cuts.
In real-world projects, angled coring is often unavoidable, whether for service rerouting, confined spaces, or meeting design requirements. But it takes the right equipment, planning, and expertise to execute safely and cleanly.
Our team combines more than a decade of experience with advanced coring rigs to ensure angled coring is done with precision, while keeping structural integrity intact. It may be harder, but with the right approach, it’s never impossible.
