Patented SDS series Drill Bits cutter
In concrete fastening projects, the quality of the drilled hole often dictates the final pull-out strength and safety of the anchor. Sheh Kai Precision breaks through the limits of traditional brazing by integrating exclusive geometric designs with high-temperature diffusion welding technology to create the next generation of Solid Carbide Hammer Drill Bits. We are dedicated to providing professional engineers with a more precise, durable, and efficient solution for reinforced concrete applications.
I. Core Technology: 1400°C Diffusion Welding vs. Traditional Brazing
Traditional Limitations: Conventional drill bits typically use inserted carbide tips fixed by copper brazing, which has a heat resistance limit of only 650-800°C. When drilling into hard rebar or deep holes, the friction generates intense heat that can melt the brazing point, causing tip detachment or breakage.
We achieve an atomic-level bond between the solid carbide head and the steel shank in an extreme environment of 1400°C.
- Thermal Shock Resistance: The bond remains stable even when directly striking rebar, demonstrating superior high-temperature stability.
- Monolithic Structure: Completely eliminates the risk of tip separation caused by heat, significantly extending product lifespan.
II. Geometric Design: Solid Carbide 3-Cutter / 4-Cutter Head
Unlike traditional flat-tip designs, Sheh Kai's SDS-Plus and SDS-Max series feature 3-Cutter and 4-Cutter solid carbide head designs:
-
Perfect Round Holes (Concentricity):
Multi-cutter designs ensure concentricity during drilling, producing perfectly round holes. This is critical for Screw Anchor installation, as a precise hole ensures optimal thread engagement with the wall for maximum holding power. -
Rebar Resistance:
Optimized cutting angles and solid tungsten carbide material provide excellent impact resistance during high-speed drilling, effectively cutting through rebar without jamming. -
3x Lifespan:
Tests show that Sheh Kai’s solid carbide heads offer 3 times the lifespan of traditional 2-cutter bits, significantly reducing consumable costs.
III. Dust Removal Efficiency & Safety
Efficient debris evacuation is key to increasing drilling speed and preventing jamming. Sheh Kai drill bits utilize a Unique Flute Design:
- 25% Higher Removal Rate: Exclusive geometry improves dust extraction efficiency by up to 25%.
- Reduced Dust Explosion Risk: The optimized combination of the cutter head and flute minimizes dust clogging and the risk of dust explosions during deep-hole operations.
IV. Eco-friendly & Specialized Solutions
For sites with strict environmental and safety requirements, Sheh Kai offers advanced product lines:
Vacuum Cleaner Drill Bit
Drills and vacuums simultaneously, removing over 90% of dust. This protects operator health and achieves "Drilling and hole cleaning in 1 step," eliminating the tedious cleaning process before Chemical Anchor installation.
Stop Drill Bit
Designed specifically for Drop-in Anchors, equipped with a stop ring to ensure precise and consistent drilling depth, preventing installation errors.
Sheh Kai Precision drill bits are not just tools; they are the first line of defense for fastening quality. From our patented 1400°C welding process to our commitment to perfect concentricity, we embody the promise of "Precision." Whether for high-strength reinforced concrete or efficient systematic installation, Sheh Kai provides the most reliable support.
