Drill bits are the cutting tools of drilling machines They can be made in any size to order but standards organizations have defined sets of sizes that are produced routinely by drill bit manufacturers and stocked by distributors In the U S fractional inch and gauge drill bit sizes are in common use In nearly all other countries metric drill bit sizes are most common and 5 4 2019 nbsp 0183 32 The metric system is used to define metric drill bit sizes as well If you have this set or need to match just use a simple formula to convert from metric to fractional inches and vice versa Converting from millimeters into inches Multiply by 0 0397 1 2022 nbsp 0183 32 Average Drilling Rate 18 ft hr 15 ft hr Bit Size 7 7 8 in 7 7 8 in Bit Weight 30 000 lbs 40 000 lbs Rotary Speed 85 rpm 60 rpmCurrently in the drilling industry there are two main categories of drilling bits rolling cutter bits and fixed cutter bits Plus bit sizes vary from 3 7 8 inch to 36 inches 1 Rolling Cutter Bits Rolling cutter bits which some may also call roller cone bits or tri cone bits have three cones Each cone can be 17 1 2022 nbsp 0183 32 Twist bits can be operated with both a manual drill as well as an electric drill and are available in sizes 0 8mm to 12 mm Most points on a twist bits are situated at a 118 degree angle which is perfect for when working with wood metal and plastic
