Low Noise Drill (LND) Slow Water Pump and Core Drill Bit System
Designed for Use with Standard Drill Chucks and the low Noise Drilling System.
The pump and cores drill is a universal low noise water pump and diamond core drill bit system designed for use with the low noise drill. The water feed arbor has a straight shank that can be accepted by a standard drill chuck, or with custom adapters can be used with many specialist drills on the market today.
The drill bit - The core drill itself is a very high quality continuous 7mm diamond crown core drill bit with extension tubes that can form a maximum length of 320mm. This is particularly suitable for very thick walls, where an entire length of 320mm cannot be accommodated by a drilling system. One section at a time can be fitted, until the desired depth is reached.
The Pump – Fully self contained, battery powered, inside a thick aluminium enclosure is a DC motor and gearhead. Designed for slow operation the pump will drip-feed water through the core drill bit at a rate of between ~5 and 25ml per minute. As a rough guide, the pump set at ~15 rpm (will give the approximate flow rate at the cutting face of a fast dripping tap.
Despite it's very slow speed and flow rate, the peristaltic pump head provides enough pressure to effectively flush slurry from the cutting face. The slurry water is recycled with a specially designed water collector. The water bottle is easy to connect, clean, fill and replace.
The control is extremely simple. The pump is started and stopped with one IP65 switch on top of the enclosure, and the speed is adjusted via a simple speed control knob. The battery is charged via the IP68 connector on the rear of the unit.
The Bottle - Sediment will settle at the bottom of the bottle. A filter is fitted to the end of the output tube inside. The bottle is easy to empty, rinse and refill if necessary. Very fine particles may remain suspended in the recycled water. This is normal and does not affect the cutting or cooling effect at the drill face.
