Our vacuum brazed heavy-duty core bits (high-performance diamond hole saws featuring precision CNC-machined heavy-duty steel bodies and metallurgically brazed diamond segments) are engineered specifically for aggressive, rapid, and deep hole drilling in tough, dense, and highly abrasive materials. Utilizing advanced high-temperature vacuum brazing technology, industrial diamond grit is chemically bonded directly onto robust steel barrels, delivering exceptional bond strength, heat tolerance, and extended service life in both heavy-duty dry and wet drilling operations.
They are extensively utilized across stone fabrication, building construction, countertop installation, and heavy infrastructure drilling sectors:
Granite, Quartz & Engineered Stone: Essential for drilling clean faucet, pipe, and sink openings on tough granite slabs, quartz countertops, and hard marble surfaces.
Concrete & Reinforced Masonry: Ideal for penetrating cured concrete, brickwork, masonry blocks, and building facades during plumbing and electrical installations.
Heavy Porcelain Slabs & Ceramics: Perfect for fast, chip-free hole cutting in thick porcelain tiles and large-format architectural ceramic panels.
Composite Materials & Abrasive Stones: Applied for heavy-duty hole making in hard fiber-reinforced polymers, refractory ceramics, and natural sandstone.
Vacuum Brazed Diamond Technology: High-temperature vacuum brazing creates a chemical bond between diamond grains and the steel core, preventing premature diamond loss and enabling fast, aggressive cutting under extreme stress.
Heavy-Duty CNC Machined Steel Body: Engineered with thick-wall alloy steel barrels precision turned and threaded on multi-axis CNC lathes (M14, 5/8″-11, or hex shanks) to guarantee perfect concentricity, zero wobble, and maximum resistance to bending.
Dry & Wet Drilling Capability: Exceptional thermal resistance allows high-speed dry drilling without immediate tool breakdown, as well as wet drilling for extended tool longevity.
Side Protection & Rapid Debris Removal: Features vacuum brazed diamond grains on the outer/inner side walls to reduce friction, allow fast swarf evacuation, and maintain clean side clearance.
Versatile Specifications & Thread Customization: Fully customizable in terms of drilling diameters (6 mm to 150+ mm), total length, wall thickness, arbor thread standards, and custom laser branding.
