Technical Information for Vulcan Drill High feed and precision machining with our specially designed point edge Vulcan Drill > High feed and precision machining due to specially designed point edge > Vulcan drills ensure longer tool life under high speed condition because of increased thermal & wear resistance. It also uses a PVD coating with an exclusive substrate to help maintain reduced frictional resistance > Low cutting resistance by the best design of clearance angle is possible to increase feed > Smoother chip control due to improved chip breakage > Rmax: 6 25s, Hole tolerance: IT8 10 > Strong shock resistance ensures long tool life under the heavy interrupted machining Code system 205=020.5 Tool Dia. 100L 100mm FLUTE length Type Workpiece Vulcan Drills MA MBA LA LBA General steel, Ductile cast iron Mild steel, Low carbon steel General steel, Ductile cast iron Mild steel, Low carbon steel Overall length 200L 200mm Shank Dia. 32S 032 Application for Vulcan Drill Workpiece - General steel, Alloy steel, Mild steel, Dice steel, Stainless steel, Cast iron, Ductile cast iron, Non-ferrous metal, etc Notice Unsuitable drilling Avoid the inclination or unevenness of entering and piercing section of hole as possible Reduce the feed 0.1 0.15mm/rev when drilling at inclined and unevenness Clamping of workpiece In case of wide flat panel or rotation by horizontal component, please clamp to be prevented bending of central part of workpiece for high efficiency Recommended cutting condition Form Workpiece Hardness 015 02O 04O vc(m/min) fn(mm/rev) vc(m/min) fn(mm/rev) vc(m/min) fn(mm/rev) Mild steel, General steel, Alloy steel Under HB250 40 90 (65) 0.15 0.30 (0.20) 40 90 (65) 0.20 0.40 (0.30) 40 90 (70) 0.20 0.45 (0.35) MA LA General steel, Alloy steel Under HB320 40 90 (60) 0.10 0.25 (0.20) 40 90 (60) 0.15 0.35 (0.25) 40 90 (65) 0.20 0.40 (0.30) Mold steel HB250 40 70 (50) 0.10 0.25 (0.20) 40 70 (50) 0.15 0.30 (0.25) 40 70 (50) 0.20 0.35 (0.30) Stainless steel HB250 30 50 (45) 0.10 0.20 (0.15) 30 50 (45) 0.15 0.25 (0.20) 30 50 (45) 0.20 0.30 (0.25) Ductile cast iron - 50 100 (70) 0.20 0.35 (0.30) 50 100 (70) 0.20 0.40 (0.35) 50 100 (70) 0.25 0.50 (0.40) MBA Mild steel, General steel, Alloy steel Under HB250 40 90 (75) 0.20 0.40 (0.30) 40 90 (75) 0.20 0.40 (0.30) 40 90 (80) 0.20 0.45 (0.35) LBA General steel, Alloy steel Under HB320 35 80 (55) 0.15 0.30 (0.25) 35 80 (55) 0.15 0.30 (0.25) 40 80 (60) 0.15 0.40 (0.30) J.
