Vacuum brazed drills are used by tilers for drilling holes for sinks, wall plugs, lights and drains. They can be used dry, making them easy to use on site and in finished bathrooms. They are economical and can drill from 4 holes (in 20mm structural porcelain) to 40 holes in some tile.
The life of the drill will depend greatly on the operating conditions. ON smaller sizes they are wax filled, allowing the wax to melt during use and lubricate the workpiece.
A spray bottle or sponge with water will greatly increase the effectiveness of these drills.
We also have adapters to convert these drills to SDS,CNC, Core drill machines and many other applications.
We stock sizes from 6mm to 125mm, a huge range at wholesale prices.
SAFETY WARNING: Only use dry on materials that are safe to be worked dry. Contact the material supplier to confirm suitability and check safety data sheets on the material. Always use appropriate PPE when working dry and ensure appropriate dust control measures are in place.
