Mirror Polish - Sharpest edge possible, extremely slowing sharpening. Grits past this stage provides only modest benefit. Near Mirror Polish - Edge is very near perfect. Very sharp edge better than most factory edges on good knives.Įxtremely Fine - Edge is extremely sharp. Edge sharpness equivalent to majority of factory edges on knives, tools.Įxtra Fine - Slow sharpening rate. Finer than medium but sharpening rate slower.įine - Modest sharpening rate, leaves metal edge with frosted appearance. Edge does not appear scratched but frosted. Medium Fine - Minimum recommended grit for final stage of most knives. Medium - Good metal removal rate, light sctaches edge. Finest recommended grit for dull tools and knives. Medium Coarse - Fast metal removal rate, scratches not as visible. LevelĮxtremely Coarse - Fastest metal removal, leaves very visible scratches in cutting edge.Ĭoarse - Very fast metal removal, leaves visible scratches in cutting edge. Each of the levels links to a page where we've selected stones that meet that grit range. Since one person's "fine" and one manufacturer's "fine" may mean something completely different we established a 1 to 10 grit chart with 1 being the most coarse and 10 being the finest. It is also available in some of the finest grit sandpapers available, going up to 2,000 grits.We decided to come up with a grit chart based on 10 levels. Wet/Dry Silicon Carbide Sandpaper - This type of sandpaper gives you the option of wet or dry sanding thanks to it’s waterproof latex-backed paper.Our non-loading sandpaper is made with a special zinc stearate coating that acts as a lubricant to prevent this from happening. Non-loading silicon carbide sandpaper - With heavy use, this type of sandpaper is prone to heating up and/or loading (gumming up).Empire Abrasives carries two variations of this sandpaper: The hardness of silicon carbide makes it one of the preferred sandpapers for marble and glass sanding and polishing, though it can be used for metal and wood surfaces as well. The silicon carbide grains are an even harder grain than aluminum oxide, measuring about 9.5 on the Mohs scale. Aluminum oxide sandpaper is an incredibly versatile abrasive that can be used for hand sanding most materials from wood and plastic to drywall and ferrous/non-ferrous metals. That’s the same scale that rates diamonds as 10 for being the hardest. Aluminum Oxide SandpaperĪluminum oxide grains are an incredible strong man-made material that measures about 9 on the Mohs Hardness Scale. Empire Abrasives carries three of the most useful types of sandpaper with 2 different abrasive grain options: silicon carbide and aluminum oxide. Today you can find sandpaper in a wide variety of abrasive types which can be used for different types of surfaces and different kinds of jobs. Sanding bare surfaces and removal of planing marks The extremes of these numbers are rarely used, but below is a sandpaper grit chart with some of the most used sizes and their common applications: The finest sandpaper can be found in a 2,500 grit and the coarsest sandpaper goes down to a 12 grit. Simple Sandpaper Grit Chart (Wood Sanding) Each grit number is useful for different tasks and on different surfaces.Ī high number grit means a finer textured sandpaper with smaller abrasive particles, and a lower grit number is a rougher/coarser sandpaper with larger abrasive grains. Besides the abrasive material, sand paper grit sizes are one of the most important features to consider when buying sandpaper. The number that you see associated with sandpapers’ grit depicts the size of the grains coating the paper. Sandpaper is a coated abrasive made by adhering similar grit size abrasive grains to one side of a thick paper or cloth material with a resin bond or glue-like adhesive. Modern day sandpaper isn’t actually made of sand, nor does it always use paper. It’s a versatile consumable product that you’ll find in most toolboxes around the world. Sandpaper is one of the original abrasive products used by anyone from professional metalworkers and woodworkers to DIY hobbyists and knifemakers to shipbuilders.
