This type of rasp is designed to be the most versatile, allowing you to quickly file down the rough edges of plasterboard but also achieve an accurate finish using the three different tooth designs.
The coarse teeth remove a large amount of material enabling you to rapidly reshape plasterboard, while the fine-toothed part of the rasp removes less material but gives a smoother, better-quality finish to the edge of the plasterboard. The third set of teeth located on the edge of the rasp is used for creating accurate, smooth internal corners for cut-out sections around light switches or 13A electrical sockets.
This rasp has a plastic handle with elastomer (rubber-like plastic) grips at its edges for improved comfort. As the rasp is used, plaster dust is channelled within the handle.
Unlike a pocket rasp where the handle or body collect the plasterboard shavings, the blade and handle of a three-file combination dry wall rasp channel the plasterboard shavings to the hole at the end of the handle where they fall out when the rasp is held vertically.
ADVANTAGES
DISADVANTAGES
Can be used to both remove large amounts of material and create a smooth surface finish
Edge teeth create accurate internal corners for plug and socket cut-outs
Removes material on both forward and reverse strokes
Fits in tool pouch and deep pockets
Longer than a pocket rasp so won’t fit in small pockets
Blades are not replaceable
Blades are made of plastic so wear quicker than other models
