- ETCHED DEPTH GAUGE for Precision Control - Our innovative etched depth markings eliminate guesswork and manual measurements. Unlike painted markings that can wear off quickly, our etched design offers improved durability and legibility throughout the job, allowing both professionals and DIYers to drill to exact depths with confidence and efficiency
- Recessed Debris Channels & CLEAR 10-INCH SCALE - Precision-milled RECESSED GROOVES run along the barrel to optimize debris removal and cooling during operation. Paired with a clearly marked 10-inch scale (with indicators at 1-inch intervals), these channels enable easy depth reading from either end of the core bit, ensuring accuracy and convenience across a wide range of core drilling applications
- Turbine-Grid & ROOF-TOP SEGMENT - Efficient Drilling: Featuring a cold-pressed turbine-grid pattern and 12mm "V-SHAPE" structure teeth, this design enables the core drill bits to achieve POWERFUL PENETRATION, accelerating cutting speed and ensuring smoother operation.The result is UO TO 10% LONGER LIFE and uninterrupted drilling in reinforced concrete
- PRO APPLICATIONS – Enhanced Durability: Diamond segments are bonded using fully automated high-strength welding that exceeds international standards, reducing detachment risk in demanding applications. Our upgraded core drill bit compound formula contains increased diamond grit, silver, and cobalt for superior durability in tough materials like old masonry and high-strength concrete
- CONSISTENT PERFORMANCE & Versatile 14" Drilling Depth - With a full 14" cutting length, this core bits for concrete handles most drilling tasks without needing multiple tools
