Hollow Core Drill Bits - Premium Diamond Core Drilling Tools
ToolWits Hollow Core Drill Bits are high‑precision diamond drilling tools designed for clean, accurate, and efficient hole cutting in a wide range of hard and brittle materials, including:
Natural stone: granite, marble, sandstone, limestone
Concrete and reinforced concrete
Ceramics, tiles, porcelain, and engineered stone
Masonry and brick
These hollow core bits are designed for professional contractors, stone fabricators, and construction engineers, offering fast cutting, long lifespan, and minimal chipping for both wet and dry drilling operations.
What Are Hollow Core Drill Bits?
A hollow core drill bit is a cylindrical diamond‑tipped tool that cuts the outer perimeter of a hole while retaining the core inside. This hollow design provides several advantages over solid bits:
Faster drilling speed due to reduced cutting surface
Clean, precise holes with minimal chipping or edge damage
Efficient removal of debris through the hollow center
Longer tool life due to reduced material wear
Hollow core bits are widely used in stone, concrete, tile, and masonry drilling, as well as geotechnical sampling and laboratory testing.
