Max4 Bowlsaver Coring System for Coring Bowl Blanks incl Tool Post


In keeping with Woodcut Tools values our objective is to always offer the best possible product. With customer feedback on the Max3 the Woodcut Tools team decided to improve on the Max3 with an even better design. ​In collaboration with Ken Port and an international team of turners, Woodcut Tools have designed, tested and developed, over many years, the latest bowlcoring product, the Max4.



Three zinc plated knives supplied that support a cut size from 75mm (3") to 450mm (18") diameter. Each knife is shaped to a radius and is supplied with a precision sharpened Stellite cutter. The large knife uniquely features a concave shape that provides solid support for the knife without the need of an additional tool rest for the knife that can be complex to operate, especially with natural edged bowls, therefore making bowl coring simple for the turner.


Knifes are manufactured from high performance steel that is proven to retain shape and therefore ensure a lifetime of efficient bowl coring.​



Bowl coring will apply pressure to the platform, especially if the wood is hard and dense. The Max4 is therefore made from precision machined cast aluminum and steel that is anodised to last and support turners to successfully core bowls small or large, wet or dry.


When coring large bowls the knife experiences immense downward pressure, to prevent the knife from twisting, the top of the large knife is supported by a machined steel post and the bottom of the lower knife is supported by a bearing.


Tail stock

Machined No 2 Morse Taper is supplied to enable integration of the Max4 product with the lathe tail stock and therefore ensures a stable bowl coring platform.3/8 - 16” threaded rod supplied to provide integrated support and stability from the No 2 Morse Taper to the Lathe tail stock.



Supplied with a 20” long handle that features double skin steel and 8 ½” long foam grip to support the turner.The 20” long handle uniquely features a spigot that supports an additional handle for further handle length and leverage if needed.



A simple adjustment of the tail stock slide on the platform will support the turner to core the shape of the bowl they require.
