I got the Marcist blade from trade tiller £ 39.09 inc p&p it will not go straight in a wet Plasplugs cutter I think the blade for the plasplugs plus cutter is 110mm the marcist is 115mm were the wheel fits in if you use a small file and file some of the plastic away it will fit and the wheel works fine so you can cut with a dry wheel on a wet cutter :hurray: :8:
