Oxi Power 300mm Diamond Concrete Core Drill Bit 1-1/4 UNC Length Heavy Duty Core Hole Saw 1817

• Primary Material: Diamond / High-Grade Carbon Steel
• Drill Bit Diameter: 300mm
• Total Length: 470mm
• Thread Type: 1-1/4" UNC
• Target Application Material: Concrete, Reinforced Concrete, Masonry

Features

• Premium Diamond Segments: Formulated for high-speed cutting and extended operational life.
• Deep Drilling Capacity: Generous 470mm length allows for deep penetration through thick concrete structures.
• Standard Universal Thread: Equipped with a 1-1/4" UNC connection for seamless compatibility with standard core drilling rigs.
• Heavy-Duty Body: Constructed with reinforced steel to resist warping and vibrations under heavy loads.
• Clean Material Ejection: Engineered to efficiently clear debris and slurry during wet or dry operation.

Applications

• Core drilling in reinforced concrete walls, floors, and foundations.
• Creating clean openings for commercial plumbing pipes and HVAC ducting.
• Drilling anchor holes for heavy machinery installation and structural anchoring.
• Electrical conduit installations through thick masonry barriers.
• Civil engineering and infrastructural concrete testing.

Usage

• Mounting: Ensure the 1-1/4" UNC thread is completely tightened and locked onto the core drill rig spindle before operation.
• Water Cooling: Use steady water flow (wet drilling) whenever possible to extend diamond life and suppress harmful silica dust.
• Pressure Management: Apply steady, moderate forward pressure. Let the diamond segments do the cutting rather than forcing the machine.
• Alignment: Maintain a perfectly straight angle throughout the drilling process to avoid binding or uneven segment wear.
