When using a drill bit for a feeler gauge please remember that many drill bits are actually undersize at the shank end of the drill bit so please use the above bit sizes with a grain of salt Also note that to correct for a broad feeler gauge or a loose fitting drill bit The chuck size refers to the maximum size of the bit that you will be able to insert into the drill As a general rule the larger the chuck the bigger the bit that you can use The size of the chuck required will often depend on the purpose that you want to use it for The most common sizes are 1 4 inch 3 8 inch and 1 2 inch Drill Size Chart FRACT SIZE SIZE LETTER SIZE METRIC SIZE DECIMAL INCHES 80 0 0135 79 0 0145 1 64 0 0156 78 0 0160 77 0 0180 5 0 0197 76 0 0200 75 0 0210 74 0 0225 73 0 0240 72 0 0250 71 0 0260 70 0 0280 69 0 0292 2 天前 nbsp 0183 32 The 2022 NFL Scouting Combine begins next week in Indianapolis There are a number of different components to the event ranging from 2022 1 24 nbsp 0183 32 Drill bits can usually be used on any brand of drill as long as the bit fits the drill s chuck Remember the chuck is the drill part that clamps onto the bit and holds it in place most chucks measure 188 inch ⅜ inch and 189 inch
