Distar RS-TX Diamond Core Bit 162 mm x 450 mm, 1 1/4 inch UNC, Wet Drilling

Drilling large-diameter holes in reinforced concrete, brick, or highly abrasive materials demands a core bit that can withstand extreme friction and heat. The Distar RS-TX 162 mm diamond core bit tackles these challenges head-on, delivering clean, precise bores for pipes, cables, and ventilation ducts. Its laser-welded, roof-shaped segments with a hard bond are engineered for professional wet drilling, ensuring longevity even when cutting through rebar and tough aggregates.

Who is it for

This core bit is built for contractors, plumbers, electricians, and HVAC specialists who regularly core through dense, abrasive substrates. If you need reliable performance on demanding job sites—where downtime from worn segments or broken barrels is not an option—the RS-TX is your workhorse.

Main features

• Laser-welded, roof-shaped segments provide exceptional cutting speed and durability.
• Hard bond formulation resists wear in highly abrasive materials and reinforced concrete.
• High-grade steel barrel maintains stability and reduces vibration during operation.
• 1 1/4" UNC thread fits standard professional core drilling machines.
• Optimized for wet drilling with water cooling to extend bit life and improve hole quality.
• 14 segments with 10 mm height and 4.5 mm width ensure consistent cutting performance.

Specifications

• Drilling diameter: 162 mm
• Working length: 450 mm
• Connection thread: 1 1/4" UNC
• Drilling method: Wet drilling
• Suitable materials: Reinforced concrete, concrete, brick, highly abrasive material

Tips

Always use water cooling to maximize bit life and maintain hole quality. Ensure your core drill machine has a 1 1/4" UNC spindle and adequate power for 162 mm diameter. Periodically check segment wear and replace the bit if segments are damaged or excessively worn.
