The Furtive Low Noise Drill (LND) replaces the SU318 Stealth LND which is no longer in production.
The Furtive LND is a rapid deployment low noise drilling system, designed and manufactured in the UK. A splash-proof battery powered control unit drives a slow, high torque, low noise drill and a peristaltic water pump. The pump enables the use of water fed diamond core drills — essential for drilling hard materials such as concrete. Operation of the control unit is simple, via individual pump/drill speed controllers and a multi-function ON/OFF/CHARGE switch. A specially designed water collector creates a 'closed circuit' system resulting in practically no mess. Waste settles in a water container and stone cores are removed with the supplied core removal tools.
The drill’s custom-built geared motor has an adjustable speed from 0-75rpm. A 10mm keyless chuck enables the use of other 'dry' drill bits and pin-holing tools. An innovative ‘Auto-Push’ device relieves the operator and provides an accurate and consistent driving force of 50 newtons (5 kgs) to the drill. For main hole drilling, special 10mm diameter thin-wall core drill bits are supplied.
For pinhole drilling, the kit includes a 1mm drill holder attachment (and 1mm drill bits) that are used with the supplied extension tubes.
The typical sound level from the entire system drilling concrete with water at ~35rpm is 39-42db.
