Core Drill Bit, 3-1/2 inch Diameter, 14 inch Drilling Depth, 1-1/4 in-7 Internal Thread, High-Precision Welding Technology
Highlights:
1.High Compatibility: The 3-1/2 in wet core drill bit utilizes a 1-1/4 in-7 universal thread, allowing quick and easy attachment to standard handheld drills or stand drills, providing versatility and convenience
2.Wet Driller: This diamond wet coring bit is suitable for wet-cutting conditions. It reduces heat buildup that can affect performance for an extended lifespan. It also lowers friction resistance and boosts drilling speed for efficient operation
3.Durable & Sturdy: Crafted from quality carbon steel with high-precision welding, this concrete core drill bit boasts 95HRB hardness. It resists heat buildup during high-speed drilling, avoiding blade detachment and enhancing longevity
4.High-Performance Drilling: Our core bits for concrete features precision-ground teeth for smooth, burr-free edges and faster, accurate cuts. The tooth center aligns with the installation axis, resisting wobbling or shifting during high-speed rotation
5.Wide Application: Ideal for drilling through reinforced concrete, red brick, concrete, and foam brick. This core bit is commonly used in air conditioning installations, plumbing, stair railings, highways, airports, and various constructions
