3. Core Craft & Performance Advantages
1. High-Adhesion Vacuum Brazing Technology, No Tooth Falling & Stable Sharpness
Adopts closed-loop high-temperature vacuum brazing craft, diamond grains are firmly welded on the segment base with strong bonding force, effectively solving common defects of electroplated bits like easy sand falling & fast dullness. The cutting edge maintains stable sharpness in long-term continuous drilling, no frequent grinding or replacement required.
2. 15mm Super High Diamond Grit Height, Extra Long Service Life
Upgraded 15mm grit height design, far higher than conventional 8-10mm grit bits. Large wear margin supports hundreds of holes drilling on brick wall & concrete materials, effectively reducing bit replacement frequency and comprehensive construction consumable cost.
3. Spiral Rib Anti-Vibration Drill Barrel, Smooth Drilling & Low Jamming Risk
Unique outer spiral rib structure on drill barrel:
4. Optimized Segmented Tooth Structure, Fast Positioning & Efficient Cutting
Segmented tooth layout with independent chip removal gaps, quick positioning at initial drilling stage without wandering deviation. Multiple cutting edges share cutting pressure, drilling speed is 20%-30% faster than ordinary sintered bits on brick & lightweight concrete, improving overall construction progress.
5. Hexagon Standard Shank, Wide Tool Compatibility
Universal hexagon connecting shank fits most mainstream domestic & imported vertical water drill rigs, no extra adapter needed for direct installation. Large contact area transmits torsion evenly, avoids idle slipping under high power output, reduces machine vibration and improves operation safety.
Practical Drilling Performance
4. Wide Application Scenarios
🏠 Home Decoration & Renovation Projects
Perfect for air conditioner wall through holes, range hood exhaust holes, hydropower pipeline reserved holes, floor drain holes in residential renovation. Efficient drilling does not damage original wall structure, ideal for decoration teams daily batch construction.
🏗️ Municipal & Infrastructure Construction
Suitable for municipal road sampling inspection, fire pipeline through holes, drainage pipe pre-buried holes, building foundation detection holes. Adapt to long-time high-intensity continuous operation of engineering construction sites.
🧱 Masonry & Civil Engineering Construction
Works well on red brick wall, aerated block, cement brick, masonry wall and other building materials, widely used in rural housing construction, old building reconstruction, wall modification drilling work.
🛠️ Professional Drilling Service Teams
Brazed bits balance drilling speed and service life perfectly. Low replacement frequency cuts downtime loss, stable drilling efficiency raises team daily construction volume, effectively controlling long-term tool procurement cost.

7. Common FAQ
Q1: What materials can this brazed water drill bit drill?
A1: It works great for aerated brick, red brick, masonry block, ordinary concrete, lightweight reinforced concrete. Not recommended for dense thick steel bar reinforced concrete, sintered core drill bits are more suitable for heavy rebar scenarios.
Q2: Is water cooling mandatory for use?
A2: Yes. Continuous water cooling takes away drilling high temperature to prevent brazing layer burnout, meanwhile washes away drilling residue to avoid drill stuck, greatly prolongs bit service life.
Q3: Which drilling machines match the hexagon shank?
A3: Compatible with most mainstream vertical engineering water drill rigs with hexagon chuck. Round shank customization or matched adapter can be provided if you use round shank drill machines.
Q4: When does the drill bit need replacement?
A4: When the 15mm diamond grit is worn flat obviously, drilling speed drops sharply and cannot cut into wall normally, the segment reaches wear limit and needs timely replacement.
Q5: What is the bulk order delivery time?
A5: Conventional in-stock sizes ship within 3 working days; customized size, packaging and logo orders take 7-15 working days based on order quantity, stable factory capacity guarantees on-time delivery.
