RT 800 WP - Guhring

RT 800 WPThe proven interchangeable insertdrilling system with highest cuttingperformance and economy -now with spiral flutes

RT 800 WPIf you predominantly produce deep holesin the diameter-range 16.0 to 40.5 mm, youshould take a closer look at type RT 800WP. The holder is nickel-plated with coolantducts, the interchangeable inserts are producedin ultra fine grain carbide. Type RT 800WP offers exceptional performance, especiallycompared to brazed carbide tools. Withregard to accuracy and surface quality ofthe hole the RT 800 WP drilling systemoffers outstanding efficiency:• high rigidity and optimumchip flow thanks to compactdesigh with spiral flutes,for the drilling depths3xD, 5xD and 7xD.• highest economic efficiency through highfeed rates due to complete 2-edged pointgeometry = Ratio geometry.• outstanding hole qualities through lateralcircular lands on the inserts.• indexing with adjusting screw in tool holder.The clamping screw ensures accurateand solid positioning.The interchangeable insert can be replacedquickly with ease in the clamped holderdirectly on the machine.Cutting rates for materials to be machinedcan be found on page 10.2

RT 800 WP . General technical informationGUHRINGGUIDE . Application recommendations• tools with bold feed column nos. are preferred choice.• for through holes supporting lands mustremain in permanent contact.• for 7 x D, centering is recommended with equal toor larger than 140° point angle tomin. 2/3 cutting edge diameter.• interrupted cutting (grooves, transverse holes) is not recommended.without prior tests. For interrupted cutting (max. 0.2 x D) it is recommendedto reduce the feed rate whenever possible.• in contrast to conventional indexable inserts, RT 800 is also suitablefor the drilling of stacked sheets.• when replacing the inserts, it is recommended to also replace theoriginal clamping screw with the included polyamide-coated screw.If this screw proves difficult to screw in, unscrew it again and removeany excess plyamide-coating.Drill-Ømm16,0020,0025,0031,5040,000,1000,1250,1600,1600,200Material groupFeed column no.1 2 3 4 5 6 7 8f (mm/rev.)0,1250,1600,2000,2000,250Common structural steelsFree-cutting steels0,1600,2000,2500,2500,315Unalloyed heat-treatable steelsAlloyed heat-treatable steelsUnalloyed case hardened steelsAlloyed case hardened steelsNitriding steelsTool steelsHigh speed steelsSpring steelsStainless steels, sulphuredausteniticmartensiticHardened steelsSpecial alloysCast ironSpheroidal graphite iron andmalleable cast ironChilled cast ironTitanium and Ti-alloysAluminium and Al-alloysAl wrought alloysAl cast alloys ≤ 10 % Si> 10 % SiMagnesium alloysCopper, low alloyedBrass, short-chippinglong-chippingBronze, short-chippingBronze, long-chippingDuroplasticsThermoplasticsKevlarGlass/carbon fibre0,2000,2500,3150,3150,4000,2500,3150,4000,4000,5000,3150,4000,5000,5000,6300,4000,5000,6300,6300,8000,5000,6300,8000,8001,00090,6300,6300,8001,0001,250Surface finish:brightS TiN-coatedF FIRE-coatedMaterial specific coolants:soluble oiloilairMaterial examples, new description (further in brackets)Figures in bold = material no. to DIN EN1.0035 S185(St33),1.0486 P275N(StE285),1.0345 P235GH(H1),1.0425 P265GH(H2)1.0050 E295 (St50-2), 1.0070 E360 (St70-2), 1.8937 P500NH (WStE500)1.0718 11SMnPb30 (9SMnPb28), 1.0736 11SMn37 (9SMn36)1.0727 46S20 (45S20), 1.0728 (60S20), 1.0757 46SPb20 (45SPb20)1.0402 C22, 1.1178 C30E (Ck30)1.0503 C45, 1.1191 C45E (Ck45)1.0601 C60, 1.1221 C60E (Ck60)1.5131 50MnSi4, 1.7003 38Cr2, 1.7030 28Cr41.5710 36NiCr6, 1.7035 41Cr4, 1.7225 42CrMo41.0301 (C10), 1.1121 C10E (Ck10)1.7043 38Cr41.5752 15NiCr13 (15NiCr13), 1.7131 16MnCr5, 1.7264 20CrMo51.8504 34CrAl61.8519 31CrMoV9, 1.8550 34CrAlNi71.1750 C75W, 1.2067 102Cr6, 1.2307 29CrMoV91.2080 X210Cr12, 1.2083 X42Cr13, 1.2419 105WCr6, 1.2767 X45NiCrMo41.3243 S 6-5-2-5, 1.3343 S 6-5-2, 1.3344 S 6-5-31.5026 55Si7, 1.7176 55Cr3, 1.8159 51CrV4 (51CrV4)1.4005 X12CrS13, 1.4104 X14CrMoS17, 1.4105 X6CrMoS17, 1.4305 X8CrNiS18-91.4301 X5CrNi18-10, 1.4541 X6CrNiTi18-10, 1.4571 X6CrNiMoTi 17 12 21.4057 X17CrNi16-2 (X17CrNi16-2), 1.4122 X39CrMo17-1, 1.4521 X2CrMoTi18-2–Nimonic, Inconel, Monel, Hastelloy0.6010 EN-GJL-100(GG10), 0.6020 EN-GJL-200(GG20)0.6025 EN-GJL-250(GG25), 0.6035 EN-GJL-350(GG35)0.7050 EN-GJS-500-7(GGG50), 0.8035 EN-GJMW-350-4(GTW35)0.7070 EN-GJS-700-2(GGG70), 0.8170 EN-GJMB-700-2(GTS70)–3.7024 Ti99,5, 3.7114 TiAl5Sn2,5, 3.7124 TiCu23.7154 TiAl6Zr5, 3.7164 TiAl6V4, 3.7184 TiAl4Mo4Sn2,5, - TiAl8Mo1V13.0255 Al99,5, 3.2315 AlMgSi1, 3.3515 AlMg13.0615 AlMgSiPb, 3.1325 AlCuMg1, 3.3245 AlMg3Si, 3.4365 AlZnMgCu1,53.2131 G-AlSi5Cu1, 3.2153 G-AlSi7Cu3, 3.2573 G-AlSi93.2581 G-AlSi12, 3.2583 G-AlSi12Cu, - G-AlSi12CuNiMgMgMn2, G-MgAl8Zn1, G-MgAl6Zn32.0070 SE-Cu, 2.1020 CuSn6, 2.1096 G-CuSn5ZnPb2.0380 CuZn39Pb2, 2.0401 CuZn39Pb3, 2.0410 CuZn43Pb22.0250 CuZn20, 2.0280 CuZn33, 2.0332 CuZn37Pb0,52.1090 CuSn7ZnPb, 2.1170 CuPb5Sn5, 2.1176 CuPb10Sn2.0790 CuNi18Zn19Pb2.0916 CuAl5, 2.0960 CuAl9Mn, 2.1050 CuSn102.0980 CuAl11Ni, 2.1247 CuBe2Bakelit, Resopal, Pertinax, MoltoprenPlexiglass, Hostalen, Novodur, MakralonKevlarGFK/CFKTesn. strength Hardness CoolantN/mm 2≤500>500-850≤850850-1000≤ 700700-850850-1000850-10001000-1200≤750850-10001000-1200≥850-10001000-1200≤850850-1000≥650-1000≤850≤850≤850≤1200≤850850-1200≤400≤450≤600≤600≤450≤400≤600≤600≤600>600-850≤850850-1000≤330 HB≤40-48 HRC>48-60 HRC≤240 HB
