M16 Diamond Core Drill Bits for Concrete Wall 68-110mm
Product Introduction
The M16 Diamond Core Drill Bit is a professional tool for concrete walls (68-110mm diameter), designed for high-efficiency and precision drilling. Integrating advanced manufacturing and user-friendly design, it is essential for electricians, construction and renovation teams.
Made of premium materials, it performs well on hard materials like concrete, bricks and stones. Supporting dry drilling (no water needed), it applies to indoor electrical renovation and outdoor infrastructure, reliably creating holes for sockets, switch boxes and electrical pipelines with perfect quality.
With standard M16 interface and SDS Plus adapter compatibility, it fits most rotary hammers. Humanized design reduces fatigue and improves safety; strict quality control ensures long service life, offering cost-effective solutions for professionals and individuals.

Product Features
1. Superior Stability & Durability
Adopting integrated cutting head-base connection technology, it achieves strong metallurgical bonding, enhancing structural rigidity and load-bearing capacity during high-intensity drilling.
It minimizes tooth breakage and cutting head detachment risks caused by vibration/impact, maintaining stable operation on reinforced concrete, extending service life and reducing replacement costs.
2. Vacuum Brazed Diamond Grit for Efficient Dry Drilling
The cutting edge uses high-purity diamond grit via vacuum brazing, forming a firm chemical bond. Diamond grit is not easy to fall off, with high exposure and strong cutting ability.
30% sharper than conventional bits for faster penetration. Special grit arrangement ensures large chip-holding space and high dust removal efficiency, ideal for dry drilling, avoiding water supply trouble and protecting operator health.
3. Essential for Electricians - Versatile & Precise
Tailored for electrical installation, it adapts to concrete, bricks, stones and aerated concrete blocks. It quickly creates precise, smooth holes for sockets and switch boxes, laying a solid foundation for subsequent work.
Suitable for new construction and old house renovation, meeting high-precision electrical installation requirements, solving hard wall drilling difficulties for electricians.
4. Convenient Operation & High Productivity
Wide debris removal opening prevents blockages. Standard SDS Plus adapter enables tool-free quick connection to rotary hammers, saving replacement time for frequent drilling tasks.
The SDS Plus system absorbs vibration, reducing operator fatigue during long-term use. User-friendly design enhances operation ease and overall productivity.
Attention
Do NOT use hammer mode when operating. This bit is for rotary drilling; hammer mode causes excessive impact, leading to tooth breakage, deformation, and affecting drilling precision and safety.
Additional notes: 1. Wear protective gear (goggles, dust mask, gloves) to avoid debris and dust hazards. 2. Check bit integrity and connection firmness before use. 3. Reduce drilling speed for extremely hard materials or dense reinforced concrete to ensure stability and service life.
