1
Q1: Can I cut through Rebar with this bit?
A: Yes, particularly the Laser Welded sizes (25mm-400mm). They are specifically designed for Reinforced Concrete. We recommend reducing RPM slightly when cutting through steel to preserve segment life.
2
Q2: Is this for hand-held or rig-mounted drilling?
A: Due to the 1-1/4" UNC connection and the size range, these are primarily designed for Rig-Mounted drilling. Small sizes (25mm-50mm) can be used handheld with an adapter, but safety clutches are essential.
3
Q3: Why use Wet drilling?
A: Water is crucial for large diameter core bits. It flushes out the abrasive concrete slurry, cools the diamond segments to prevent overheating, and significantly increases drilling speed and bit life.
4
Q4: Can you make a custom length?
A: Yes, while the standard is 450mm, we can manufacture tubes in lengths of 300mm, 500mm, or 600mm to suit your specific wall thickness requirements.
