When fitting kitchen worktops using a worktop jig, it is necessary for the router cutter to be long enough to extend below the bottom of the worktop but retain a sufficient length of shank in the router collet. This can be difficult to achieve with some routers and when you add an extension to the router such as a sub-base a long shank is needed to provide sufficient protrusion from the base. It's critical that the router bit is inserted to the K Line as moving away from the line causes instability. With this in mind we have introduced a worktop cutter featuring a longer shank than usually found on this type of cutter. This ensures you have enough reach to cut safely through the work piece. These cutters also feature a bottom cut insert for efficient plunge cuts. 50mm depth of cut, 12.7mm diameter and 107mm overall in length.
