Hi Perma-Grit Tool’s here. Thank you for reviewing some of our range, that we thought may be appropriate for your craftsmen. Reading the comments it seems that our files are a little to coarse for some.
This tip may help, when using our files only a light pressure should be applied, the Grit does not degrade, unlike sandpaper the minute you start using it. When you sand with a light touch, a fine layer of dust will build up on the tool, and give you a finer finish. When you have finished, tap the tool and all the dust will be removed. The only time they will clog is if you sand a little to early, when a resin or glue has not cured. The finest tools we supply are between a 320 & 400 grit. Enjoy your building and keep well. Thank you Tracey - Perma-Grit Tool.
