Deep hole drilling Korloy twist solid drills Mach Long Solid Technical Information Stable deep hole drilling with specially designed low cutting resistance Mach Long Solid Drill Over 20D deep hole drlling is possible without step drilling The stable hole drilling due to specially designed low cutting resistance Special chip pocket has designed for effective chip evacuation Optimized design for drill rigidity to prevent the bending of the drill when entering operation The lubrication & thermal resistance of coating has been increased by adapting new TiAlN Code system MLD(P) 1200- 10 -100L x 11S -J Type Mach Long Drill MLD Pilot Drills For MLD MLDP Tool Dia. 1200=012.00 MLDP FLUTE length 10 = 10mm MLD Depth of drilling 10 = D X 10 Overall length 100L 100mm Shank Dia. 11S 011 Mach Long Drills - Deep hole drilling Application example (Oil hole for crank shaft, 20D) Mach Long Drills are ideal for Deep and inclined hole drilling of crank shaft Deep hole drilling of cam shaft Deep hole drilling of mold and machinery Deep hole drilling aspect ratio over 15D Advantages of MLD Shorting cycle time for better productivity Tool guide bush is not required Reduce idle time by prolonged tool life Green coolant solutions(MQL) to protect environment MLD productivity MLD0680-20 (06.8mm x 140 x 170L x 7S) Tool vc(m/min) fn(mm/rev) n(min-1) vf(mm/min) Coolant Step operation Gun Drills (Carbide) 100 0.04 4,683 187 Through coolant oil No required High Speed Steel Long Drills 15 0.10 703 70 Outer coolant oil 15mm / 9times Mach Long Drills 80 0.14 3,747 525 MQL- Air 0.5MPa, Oil 20cc/h No required Cycle time (min) 140 120 100 80 60 40 20 Gun Dril (Carbide) MLD HSS Long Drill (High speed steel) Advantages of MLD against conventional drills Decreasing cycle time up to 1/3 1/8 times Increasing productivity by process reduction It is easy to reduce running cost Improving of effective working condition Drill guide bush is not required Drills J. 69 0 for Mach Long Solid Drill
