China Dry Threaded Diamond Turbo Segment Core Drill Bit for Concrete Manufacturer, Exporters
Product Description
Product Introduction
Key Features
Optimized for all-weather drilling, this core bit maintains high-speed penetration in reinforced concrete. Its specialized bond matrix allows for efficient dry cutting in dust-sensitive indoor environments or wet cutting for maximum cooling.
Utilizing fully automatic laser-welding technology, we ensure an unbreakable segment-to-core bond. This industrial-grade construction resists high thermal stress, preventing segment loss and significantly extending the tool's service life compared to standard bits.
The aggressive Turbo segment design provides immediate sharpness and reduces friction. By improving chip removal and cooling, it delivers exceptional drilling efficiency, lowering your overall cost-per-hole and reducing strain on power tools.

Frequently Asked Questions
This diamond core drill bit is engineered to cut through heavily abrasive and hard construction materials, including concrete, reinforced concrete, brick, block, and masonry.
Yes, it is specifically designed with a bond matrix and segment structure optimized for dry drilling in dust-sensitive indoor spaces, while also remaining fully capable of wet drilling when maximum cooling is desired.
The bit comes in industry-standard outer diameters of 68mm, 72mm, and 82mm, featuring a standard working length of 70mm suitable for wall conduit and electrical box installations.
It features a heavy-duty M16 thread connection, providing superior torque stability. It connects seamlessly to handheld core drills and can be easily fitted with an SDS adapter for standard rotary hammers.
Fully automatic laser welding forms an unbreakable joint that prevents segment detachment under high heat. The Turbo profile reduces friction, accelerates dust extraction, and delivers faster cutting speed.
It is primarily applied in HVAC ducting and air conditioning penetrations, sanitary and plumbing pipe corridors, electrical conduit boring, wire saw starter holes, and infrastructure maintenance.
