Mk Core Bits Drill Through Porcelain, Tile, Glass, Stone, and Masonry
- Drill through porcelain, granite, marble, tile, stone, and masonry
- Vacuum Braze Technology provides the strongest bond between diamond particles and the drilling surface of core bit
- Drilling Time Reduced by 50% compared with traditional metal-bond core bits
- No bond to wear away - diamond particles work at peak performance at all times
- Reverse spiral thread delivers continuous water feed to the cutting surface areas, extends bit life and improves drilling speed
- Core ejector slot clears debris and plugs during repeated drilling operations
- Designed to operate on any corded or battery operated hand drill
- Hollow bore creates a core that guides the drill
- Diamond grit edge, no bond to wearaway
- Slotted edge and reverse thread spiral provide more water into the cut for quicker drilling and extended drill life
- Heavy-duty, single piece construction
- Core ejection slot allows continuous drilling
