DIAMOND CORE DRILL
Vertical Diamond Core Drill Machine is a specialized engineering equipment designed
for large-diameter, high-precision, deep-hole drilling operations on hard, brittle
materials such as concrete, stone, brick walls, and asphalt. Its core feature is the use of
a fixed mechanical support structure to ensure absolute stability during drilling,
combined with diamond drill bits (core bits) that efficiently cut materials through
abrasive grinding. It represents the pinnacle of precision, efficiency, and safety in
drilling operations, primarily serving professional fields with stringent requirements for
drilling quality. By sacrificing some flexibility and setup speed, it achieves unparalleled
drilling accuracy. For high-quality professional construction scenarios, it is an
indispensable piece of equipment, ensuring both project quality and efficiency.
Equipped with spirit level.
Features clutch protection.
Overload protection.
Aluminum alloy square shaft.
Feed handle with quick-release extension bar.
Optional angle base available.
