NEO TOOLS broca de núcleo diamantado 132 mm x 470 mm, rosca UNC 1 1/4 polegadas, perfuração a húmido para betão armado e alvenaria

Professional contractors and plumbing crews rely on this NEO TOOLS diamond core drill bit when installing pipework through reinforced concrete walls and floors. The 132 mm diameter bit cuts clean, precise holes for waste lines, vents, and conduit sleeves, while the 470 mm length provides ample reach for standard wall thicknesses. Laser-welded diamond segments on a high-grade steel body deliver fast, chip-free drilling in the toughest materials, and the 1 1/4" UNC thread mounts directly to most core drilling machines.

Key specifications

• Drilling diameter: 132 mm
• Overall length: 470 mm
• Connection thread: 1 1/4" UNC
• Drilling method: wet drilling (water cooling recommended)
• Cutting edge: industrial diamonds, laser-welded segments
• Body material: high-grade steel
• Compatible materials: reinforced concrete, concrete, brick, masonry, natural stone, asphalt
• Application: professional core drilling for plumbing, electrical, and HVAC installations

Why choose it

This core bit is built for demanding jobsites where speed and durability matter. The laser-welded segments resist abrasion and impact, ensuring a long service life even in heavily reinforced concrete. Wet drilling keeps the bit cool and reduces dust, while the precision-engineered geometry produces smooth, chip-free holes that require minimal finishing. The 1 1/4" UNC thread guarantees a secure fit on standard core drilling rigs, reducing vibration and improving accuracy.

Ideal use cases

• Creating openings for plumbing pipes and drains in concrete floors and walls
• Drilling holes for electrical conduit and cable sleeves
• Installing HVAC vents and ductwork penetrations
• Core drilling in reinforced concrete, brick, and masonry for structural modifications

Good to know

For optimal performance and extended bit life, always use water cooling during wet drilling operations. The bit is compatible with standard core drilling machines equipped with a 1 1/4" UNC spindle. Ensure the drill rig is securely anchored and the bit is properly aligned before starting. Replace the bit when diamond segments show significant wear to maintain cutting efficiency and hole quality.
