DrillsComposite Cutting ToolsDrilling holes in composite materials is justas important as machining. In fact, 60% ofall rejected parts are due to drilled holes.The reason for the rejection is delaminationof material caused by excessive pressurecreated while drilling. LMT Onsrud offersmany styles of solid carbide and PCD drillsbased on the material, application andaccuracy of the hole being produced.LMT Onsrud offers a wide variety of standarddrills, but realize that many special sizes arerequired. Quote request forms have beenmade in the most popular drill styles tomake the quote request process efficient.
Solid Carbide 8 Facet Drill67-800Designed to reduce cutting forces and eliminatingdelamination when exiting the material.UsageComposites, Carbon fiber, mechanicalplastics, and fiber reinforced plasticsWhat is an 8 Facet Drill?An 8 facet drill consists of4 cutting edges with2 facets per cuttingedge. These facetsconsist of the lip reliefand the lip clearance angle.X∞X∞FRACTIONAL DRILLSPart Cutting Flute SHKNumber DIA LGTH DIAOAL67-807 1/8 (0.1250) 1-1/4 0.125 2-1/467-808 9/64 (0.1406) 1-3/8 0.140 2-1/267-809 5/32 (0.1563) 1-3/8 0.156 2-1/267-810 11/64 (0.1719) 1-5/8 0.172 2-3/467-811 3/16 (0.1875) 1-5/8 0.188 2-3/467-812 13/64 (0.2013) 1-3/4 0.203 367-813 7/32 (0.2188) 1-3/4 0.219 367-814 15/64 (0.2344) 2 0.234 3-1/467-815 1/4 (0.2500) 2 0.250 3-1/467-816 17/64 (0.2656) 2-1/8 0.266 3-1/267-817 9/32 (0.2813) 2-1/8 0.281 3-1/267-818 19/64 (0.2969) 2-3/8 0.297 3-3/467-819 5/16 (0.3125) 2-3/8 0.313 3-3/467-820 21/64 (0.3281) 2-1/2 0.328 467-821 11/32 (0.3438) 2-1/2 0.344 467-822 23/64 (0.3594) 2-1/2 0.359 467-823 3/8 (0.3750) 2-3/4 0.375 4-1/467-824 25/64 (0.3906) 2-7/8 0.391 4-1/267-825 13/32 (0.4063) 2-7/8 0.406 4-1/267-826 27/64 (0.4219) 2-7/8 0.422 4-1/267-827 7/16 (0.4375) 2-7/8 0.438 4-1/267-828 29/64 (0.4531) 3 0.453 4-3/467-829 15/32 (0.4688) 3 0.469 4-3/467-830 31/64 (0.4844) 3 0.484 4-3/467-831 1/2 (0.5000) 3 0.500 4-3/4LETTER DRILLS (CONT.)Part Cutting Flute SHKNumber DIA LGTH DIAOAL67-850 A (0.2340) 2 0.234 3-1/467-851 B (0.2380) 2 0.238 3-1/467-852 C (0.2420) 2 0.242 3-1/467-853 D (0.2460) 2 0.246 3-1/467-854 E (0.2500) 2 0.250 3-1/467-855 F (0.2570) 2 0.257 3-1/467-856 G (0.2610) 2-1/8 0.261 3-1/267-857 H (0.2660) 2-1/8 0.266 3-1/267-858 I (0.2720) 2-1/8 0.272 3-1/2LETTER DRILLS (CONT.)Part Cutting Flute SHKNumber DIA LGTH DIAOAL67-859 J (0.2770) 2-1/8 0.277 3-1/267-860 K (0.2810) 2-1/8 0.281 3-1/267-861 L (0.2910) 2-1/8 0.291 3-1/267-862 M (0.2950) 2-3/8 0.295 3-3/467-863 N (0.3020) 2-3/8 0.302 3-3/467-864 O (0.3160) 2-3/8 0.316 3-3/467-865 P (0.3230) 2-3/8 0.323 3-3/467-866 Q (0.3320) 2-1/2 0.332 467-867 R (0.3390) 2-1/2 0.339 467-868 S (0.3480) 2-1/2 0.348 467-869 T (0.3580) 2-1/2 0.358 467-870 U (0.3680) 2-3/4 0.368 4-1/467-871 V (0.3770) 2-3/4 0.377 4-1/467-872 W (0.3860) 2-7/8 0.386 4-1/267-873 X (0.3970) 2-7/8 0.397 4-1/267-874 Y (0.4040) 2-7/8 0.404 4-1/267-875 Z (0.4130) 2-7/8 0.413 4-1/2NUMBER DRILLSPart Cutting Flute SHKNumber DIA LGTH DIAOAL67-876 1 (0.2280) 1-3/4 0.228 367-877 2 (0.2210) 1-3/4 0.221 367-878 3 (0.2130) 1-3/4 0.213 367-879 4 (0.2090) 1-3/4 0.209 367-880 5 (0.2055) 1-3/4 0.206 367-881 6 (0.2040) 1-3/4 0.204 367-882 7 (0.2010) 1-3/4 0.201 367-883 8 (0.1990) 1-3/4 0.199 367-884 9 (0.1960) 1-3/4 0.196 367-885 10 (0.1935) 1-5/8 0.194 2-3/467-886 11 (0.1910) 1-5/8 0.191 2-3/467-887 12 (0.1890) 1-5/8 0.189 2-3/467-888 13 (0.1850) 1-5/8 0.185 2-3/467-889 14 (0.1820) 1-5/8 0.182 2-3/467-890 15 (0.1800) 1-5/8 0.180 2-3/467-891 16 (0.1770) 1-5/8 0.177 2-3/467-892 17 (0.1730) 1-5/8 0.173 2-3/4NUMBER DRILLS (CONT.)Part Cutting Flute SHKNumber DIA LGTH DIAOAL67-893 18 (0.1695) 1-5/8 0.170 2-3/467-894 19 (0.1660) 1-5/8 0.166 2-3/467-895 20 (0.1610) 1-3/8 0.161 2-1/267-896 21 (0.1590) 1-3/8 0.159 2-1/267-897 22 (0.1570) 1-3/8 0.157 2-1/267-898 23 (0.1540) 1-3/8 0.154 2-1/267-899 24 (0.1520) 1-3/8 0.152 2-1/267-900 25 (0.1495) 1-3/8 0.150 2-1/267-901 26 (0.1470) 1-3/8 0.147 2-1/267-902 27 (0.1440) 1-3/8 0.144 2-1/267-903 28 (0.1405) 1-3/8 0.141 2-1/267-904 29 (0.1360) 1-3/8 0.136 2-1/267-905 30 (0.1285) 1-1/4 0.129 2-1/467-906 31 (0.1200) 1-1/4 0.120 2-1/4METRIC DRILLSPart Cutting Flute SHKNumber DIA LGTH DIAOAL67-961 3.00 (0.1181) 32 3.00 5767-962 3.50 (0.1378) 35 3.50 6467-963 4.00 (0.1575) 35 4.00 6467-964 4.50 (0.1772) 41 4.50 7067-965 5.00 (0.1969) 44 5.00 7667-966 5.50 (0.2165) 44 5.50 7667-967 6.00 (0.2362) 51 6.00 8367-968 6.50 (0.2559) 51 6.50 8367-969 7.00 (0.2756) 57 7.00 8967-970 7.50 (0.2953) 60 7.50 9567-971 8.00 (0.3150) 60 8.00 9567-972 8.50 (0.3346) 64 8.50 10267-973 9.00 (0.3543) 64 9.00 10267-974 9.50 (0.3740) 70 9.50 10867-975 10.00 (0.3937) 73 10.00 11467-976 10.50 (0.4134) 73 10.50 11467-977 11.00 (0.4331) 73 11.00 11467-978 11.50 (0.4528) 76 11.50 12167-979 12.00 (0.4724) 76 12.00 121www.onsrud.com 20
