3. Core Craft & Performance Advantages
1. High-Temperature Sintered Diamond Segment, Ultra Wear-Resistant
The cutting head adopts powder metallurgy high-temperature integrated sintering process. Premium high-hardness diamond abrasive is fused with metal matrix at high pressure & high temperature, the segment and drill body combine tightly without falling teeth or segment peeling. Compared with electroplated drill bits, the service life is increased by 4-6 times, and long-term drilling keeps sharp cutting force without rapid dullness.
2. Thickened Seamless Steel Tube Body, Anti-Deformation & Anti-Breakage
The drill body uses thickened seamless precision steel pipe, finished by CNC lathe and stress relief treatment. It resists bending, twisting and cracking under long-time deep hole heavy-load drilling. Even drilling reinforced concrete with dense steel bars, the drill barrel will not deform or crack, greatly reducing tool replacement cost and construction downtime loss.
3. Special Tooth Shape Design, Fast Chip Removal & Anti-Stuck Drill
The bottom adopts segmented tooth structure with reserved chip removal gaps. Drilling debris, concrete slag and sand are quickly taken away with circulating cooling water, effectively avoiding drill jamming caused by debris accumulation. The tooth tip is optimized for positioning, no wandering or deviation at the start of drilling, ensuring round and neat hole wall, no hole expansion or edge collapse.
4. Upgraded Hexagon Shank, Stable Power Transmission
Standard hexagon connecting shank fits most engineering water drill chucks closely, large contact area avoids idle slipping under high torsion output. It can steadily transmit power of high-power drilling rigs, reduce vibration during deep drilling, improve drilling verticality and construction safety.

7. FAQ
Q1: Can this sintered water drill bit drill reinforced concrete?
A1: Yes, it is specially designed for reinforced concrete. The high-hardness sintered diamond segment can cut through ordinary steel bars smoothly. Please keep stable water cooling and uniform feed speed during operation.
Q2: Is water cooling necessary when using this drill bit?
A2: Mandatory. Continuous water cooling can take away drilling high temperature, prevent diamond segment from burning and invalid abrasion, meanwhile flush drilling slag to avoid stuck drill, effectively extend the drill bit service life.
Q3: What drilling rigs can this hexagon shank drill bit match?
A3: It fits most mainstream vertical engineering water drill machines on the market with hexagon chuck. If your drill rig is with round shank interface, we can provide matched adapter or customized round shank drill bits.
Q4: How to judge the drill bit needs to be replaced?
A4: When the drill tooth segment is worn flat obviously, drilling speed becomes extremely slow and cannot cut into the wall normally, it means the segment is worn out and needs to be replaced in time.
Q5: What is the delivery time for bulk orders?
A5: Conventional in-stock sizes can be delivered within 3 working days; customized size, packaging and logo orders take 7-15 working days according to order quantity, our factory has sufficient stable production capacity to guarantee on-time delivery.
