Drill bit sharpening angle is important to cut and remove the material in an efficient way. Drill bits should be sharpened according to the hardness of the drilling materials. Metal and wood drill bits should be sharpened between 118 degrees and 135 degrees. 118-degree drill bits are suitable for soft materials, and 135-degree drill bits are suitable for the harder materials of any type of metal and wood. For the concrete, tile, and bricks you should have 100\u00b0-115\u00b0. For the PVC and fiber, you should have 50\u00b0-65\u00b0. <\/p>\n\n\n\n
You can use a drill bit angle gauge to measure the drill bit angle properly while you are sharpening it. Using the below drill bit angle chart you can sharpen any type of drill bit to drill wood, metal, concrete, brick, tile, PVC, and fibre.<\/p>\n\n\n\n
