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 underthe heavy interrupted machining O Code system Vulcan Drills MA: General steel, Ductile cast iron 200L: 200 mm MBA: Mild steel, Low carbon steel LA: General steel, Ductile cast iron LBA: Mild steel, Low carbon steel Application for vulcan drill General steel, Alloy steel, Mild steel, Dice steel, Stainless steel, Cast iron, Ductile cast iron, Non-ferrous metal, etc O Notice Unsuitable drilling - Avoid the inclination or unevenness of entering and piercing section of hole as possible - Reduce the feed 0.1-0.15 mm/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 O Recommended cutting condition Form Workpiece Hardness 015 02Q 04Q vc (m/min) fn (mm/rev) vc (m/min) fn (mm/rev) vc (m/min) fn (mm/rev) MA LA 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) 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 LBA 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) 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) G Drills 88
