Diamond Core Drill Bit for Masonry Walls , Iran

Diamond wall drill bits are constructed from a thin-walled steel tube with nickel plating. Their diameter varies from 14 to 300 mm for different applications. The effective cutting length typically ranges from 200 to 1000 mm based on required depth. High-grade industrial diamond particles of 30/40 mesh are distributed across the cutting segment. A soft, sintered cobalt-iron bond matrix is utilized. This bond enables fast cutting of abrasive materials like concrete, brick, and stone. The bits operate on core drilling rigs at 200 to 1500 RPM. A water cooling system with 2-8 liters per minute flow is essential for heat and dust suppression.

The bits are designed as one-piece or segmented with threaded connections. The standard shank features 1.25-inch threads or a quick-connect European system. The tube wall thickness ranges from 2.5 to 6 mm, balancing strength and performance. Some models feature cross slots for rapid slurry removal. Diamond core bits often have a diamond-impregnated tip profile for pilot-free starting. They can core into materials with compressive strength up to 50 MPa. Their average service life is 50 to 150 linear meters of cutting, depending on material. The dimensional accuracy of the drilled hole is typically within +0.5/-0 mm of the nominal diameter.You can order and buy Diamond Core Drill Bit for Masonry Walls from Iran by contacting us through whatsaap and email.
