RPS Tiger Boring Chains 3"/75mm

RPS Tiger Boring Chains 3"/75mm


These rotary boring chains are designed with boring/cutting/honing through hard deposits, bricks, masonry, cement and old parged lining material. The idea being that if there is a blockage, then it will drill through and open up the blockage. On the top of the chains is a 3 bladed carbon steel cutting/boring head, the teeth on this device are extremely hard as they are manufactured from tungsten carbide.


These chains are set to cut a 3" hole with 5 sided carbon steel cutting teeth. 


*Only suitable for 18mm, 20mm solid nylon rods or steel rods.

RPS Tiger Boring Chains 3"/75mm

Impuesto excluido
  • RPS customers have had great success with these chains, they have been used to remove blockages, opened up chimney widths and the removal of old restrictive chimney lining.

    There is always the very odd case where the solid lining material can be a mixture that is so hard, that either the chains take a long time to cut through or the material is just too hard and can destroy the chains. 

    RPS cannot guarantee a success or no damage to the chains when they are being used in such a way, also we will accept no responsibility if lining material can not be removed or offer a refund if the chains are damaged.

    The cost for these chains and the time to remove any material should be built into your quote/cost.
