Product Description

Industrial Dry Concrete Core Drill Bit Kit

The kit combines a diamond-tipped core bit, water-feed swivel adapter, quick-release joint, and extension rod to provide a versatile hole-cutting solution. Whether you're installing downlights, running conduit, or creating plumbing penetrations, this system delivers fast, precise, and repeatable results.
 

Features

• Premium Bearing Adapter: High-performance bearings ensure smooth rotation and maintain a leak-free water seal at high drill speeds.
• Quick-Release Water Joint: Tool-free disassembly and reassembly of the water feed assembly for rapid bit swaps, compatible with M22 threaded interfaces.
• Water Swivel Assembly: Precision-engineered swivel delivers continuous coolant flow directly through the bit's center, reducing heat and flushing debris.
• Dry Operation: Optimized tooth profile allows clean cutting with minimal dust when dry and extended bit life when used wet.
• 32-83 mm Diameter & 370-450 mm Cutting Depth: Ideal for thick walls and deep installations.
• SDS-Plus Compatibility: Standard SDS-Plus shank fits most rotary hammers and impact drills.
• Extension Rods: Available up to 400 mm lengths for through-wall drilling without additional extensions.

FAQ

1. Pilot Positioning: Begin with a small pilot bit through the center to guide the core bit and prevent wandering.
2. Drill Mode: Use rotary-hammer mode for concrete; switch to standard mode for brittle materials like tile.
3. Water Supply: Maintain a steady flow of water in wet mode to minimize dust and cool the bit.
4. Chip Clearance: Withdraw the bit periodically to eject debris and reduce binding.
5. Safety Gear: Always wear eye, ear, and respiratory protection when drilling.
