Choose your tool WALTER TITEX in accordance with the drilling depth or DIN (e.g. 3 x Dc or DIN 338) in accordance with the machining conditions (see step 2 b C) for the relevant machining group (see step 1 P1-P15 M1-M3 O1-O6) STEP 5 Choose your cutting data from the table from page B 358 onwards Cutting speed vc VCRR (vc rating chart for micro drills) Feed VRR (feed rating chart) Go to the row of your machining group (e.g. K5) and the column of your selected drilling and boring tool. You will find the cutting speed vc or the VCRR and VRR there. The vc rating chart (VCRR) and the feed rate chart (VRR) can be found from page B 388 onwards. 2 =t5 cutting data for wet machining dry machining is possible, cutting data must be selected from TEC Drilling depth 3 x Dc Designation A3289DPL A3285TFL A3885TFL E Emulsion O Oil M MQL L dry Type Xtreme Plus Alpha 4 I Dimensions DIN 6537 K DIN 6537 K I Dia. range (mm) 3.00 20.00 3.00 20.00 vc cutting speed VCRR vc rating chart from page B 382 VRR feed rating chart from page B 384 Cutting tool material K30F 1 Coating DPL TFL 1 Page B 70 B66/B 102 i1 Grouping of main material groups and identification letters Brinell hardness HB Tensile strength Rm S 1 l Workpiece material =3 X =3 vc VRR vc VRR P Nl"-a'ly'a C< 0.25 % annealed 125 428 P1 200 16 120 12 1 C > 0.25 < 0.55 % annealed 190 639 P2 180 12 105 12 C > 0.25 < 0.55 % tempered 210 708 P3 170 12 100 12 C > 0.55 % annealed 190 639 P4 180 12 105 12 i C > 0.55 % tempered 300 1013 P5 140 12 75 9 I machining steel (short-chipping) annealed 220 745 P6 200 16 120 12 j Low alloy steel annealed 175 591 P7 180 12 105 12 < tempered 300 1013 P8 140 12 75 9 1 tempered 380 1282 P9 100 8 O E 50 6 O E i tempered 430 1477 P10 80 O E 42 O E i High-alloyed steel and high-alloyed tool steel annealed 200 675 P11 85 9 67 9 j hardened and tempered 300 1013 P12 120 10 60 hardened and tempered 400 1361 P13 80 6 O E 42 O E i Stainless steel ferritic/martensitic, annealed 200 675 P14 85 9 67 9 1 martensitic, tempered 330 1114 P15 50 9 42 M Stainless steel austenitic, quench hardened 200 675 M1 50 6 42 i austenitic, precipitation hardened (PH) 300 1013 M2 63 6 56 6 i ausfnitic/ferritic, duplex 230 778 M3 40 6 34 B 15 Drilling WALTER TITEX STEP 4
