Circular keyhole saw with variant spacing
Circular keyhole saws are a combined tool consisting of a centring drill and drill bit, in order to make the holes required on site quickly and easily, e.g. for drilled clips. They are used for sprinkler clips, e.g. type VIROTEC®-VTS, for other drilled clips and flow indicators. Only the drill bit has to be changed according to the required drill hole diameter and not the whole tool. The circular key hole saws can be clamped using three-jaw chucks.
The circular keyhole saw consists of the following components:
VIROTEC®-thread sealant VFD
simple and fast handling
The VIROTEC®-thread sealant is a liquid, anaerobic sealant for sealing metal pipe connections. Due to its quick and easy use it is a cost-effective alternative to conventional sealants such as hemp or Teflon tape.
VIROTEC® VFD thread sealant is an anaerobic sealant which only cures and seals without air and on contact with metal. The pro - duct is therefore not suitable for installing non-metal threads (e.g. plastic). The air in the bottle keeps the product liquid.
VIROTEC® thread sealant is a liquid sealant for use on pipe threads e.g. to DIN 2999 (ISO 7-1). It is simply applied to the front part of the outer and inner thread. The dispensing tip on the bottle makes it easy to position the product on the thread. When the thread is screwed the product spreads between the threads and completely cures there after 8 – 24 hours. This ensures secure sealing up to a pressure of 100 bar. The connection can be undone. The break-away torque depends on the thread diameter. VIROTEC® thread sealant is available in two container sizes, VFD- 50 with 50 ml and VFD-250 with 250 ml contents.
