Original title The specifications of the drill bit are complete and the arrangement is too complete Drill is a tool used to drill through holes or blind holes in solid materials and to ream existing holes The commonly used drill bits are twist drill flat drill center drill deep hole drill and trepanning drill It is customary to classify reamers and counterbores as drill bits although they cannot make holes in solid material The dth rock bit specifications of various drill bits are shown in the table below Drill size 180 degrees Specification Small diameter Large diameter Full length Small diameter Blade Long handle diameter M33465651365 M4458075188 M55595852295 M666110902511 M8901401002812 M101101751103012 M121402001153212 1/4685110902511 5/168551401002812 3/81011501103012 1/21352001153212 Drill size 90 degree Specification Small diameter Large diameter 04005-005053031 05005-005063031 06005-005073536 07005-005083536 08005-005094036 09005-005104036 10005-005124036 1240100 12005-005145042 15005-005185042 1850100 1850150 1850200 20008-008245042 246 dhd drill bit 0100 2460150 2460200 25008-008306047 3080100 3080150 3080200 30008-008367757 36100100 36100150 36100200 32008-008387757 40008-0084810069 48100100 48100150 48100200 50012-0126011069 60120100 60120150 60120200 60012-0128016090 80012-012100180100 100012-012120180100 120012-012150220110 High-speed steel hollow drill bit also known as core drill bit or hole opener drill bit classification high-speed steel drill bit hard alloy drill bit tungsten steel drill bit; cutting depth 35MM 50MM 100M; suitable for drilling machine imported magnetic seat drill magnetic drill domestic magnetic seat drill magnet drill magnet drill steel mining dth bit plate drill magnetic drill machine tool bench drill seat drill and so on Diameter specification 12mm to 100mm; the main material of drill bit is high-speed steel Powder metallurgy
Drill bit reamer In order to meet the needs of mass production the front end is a drill bit and the rear end is a reamer The diameter of the drill bit and the diameter of the reamer are only the margin of reaming There are also drill bits used in combination with screw tapping so they are also called mixed drill bits (7) Taper drill Taper drill can be used when machining the feed inlet of the mold (8) Cylindrical hole drill We call it a countersunk end mill The front end of this kind of drill has a part with a smaller diameter which is called the lead (9) Taper hole drill It is used for drilling taper holes Its front end angle is 90 ° 60 ° etc The chamfering cutter we use is a kind of taper hole drill Source Booz UG Programming Studio Return to Sohu to see more Responsible Editor wt-dthtools.com
