Multi-Drills Replaceable Head Type MULTI-DRILLs SMDType Large Hole MTL Type Improved chip management for highly malleable materials Large Helix Angle Design For Large Holes Tool edge design ideal for malleable material used for large casings, etc. Edge design suitable for malleable material commonly used for large hole drilling. Reduces movement when starting the hole X-TypeThinning Aims to reduce thrust under heavy cutting Large Thinning Angle Designed to handle low machineandclamprigidity Edge Treatment Exclusively for Large Diameters Prevents unexpectedbreakage when working with expensive materials Robust Substrate Machined SurfaceAccuracy Work Material: St52-3 (Base substrate for construction use) DrillSize: 033,0mm x 5D Cutting Conditions: vc=120m/min, f=0,25mm/rev Cutting Environment: Emulsion Type High drilling accuracy with large diameters 033,15 033,10 Exit 033,05 033,00 035,95 032,90 032,85 Measured Point (1) Measured Point (2) Cutting Force Comparis on (Thrust) Work Material: St42-2(Laminated plates) Drill Size: 037,5mm x 0D Cutting Conditions: vc=90m/min, f=0,35mm/rev Cutting Environment: Emulsion Type Stable even when machining laminated plates Cutting Force (N m) 10,000 8,000 6,000 4.000 2.000 0 15 20 25 Depth of cut (mm) Recommended Cutting Conditions vo=Cutting Speed (m/min) f=Feed Rate (mm/rev) Work Material Soft Steel ( HB250) General Steel (HB250 320) Hardened Steel (HRC45) Stainless Steel ( HB200) Grey Cast Iron Ductil Cast Iron Recommended Head MTL Type MTL Type MTL Type MTL Type MTL Type MTL Type Drill 0 (mm) Cutt.
