SEC-MultiDrill SMD Type MFS Type  Ideal for drilling on non-flat surfaces and less burr DEX Coating Utilizes RS Thinning for high rigidity ● Various drilling operations thanks to a point angle of 180° Applicable to high-efficiency spot facing, drilling in non-flat surfaces such as inclined and cylindrical surfaces, and interrupted drilling. Also reduces burrs at the hole exit. ● Improves machining stability Sharp edge for excellent Achieves high rigidity by employing RS Thinning, which ensures thick web at the bottom. entry into the material Strong peripheral cutting edge ■ Performance Hole Accuracy Comparison Cutting force Comparison 14.05 max MFS Type ▲（▲）ave 14.04 min Hole Diameter (mm) 14.03 14.02 14.01 Competitor A 14.00 13.99 13.98 MFS Type Competitor A Tool : SMDH140S + SMDT1400MFS Work Material : S50C Cutting Conditions : vc=100mm/min f =0.15mm/rev Hole Depth 21mm Wet ■ MFS Type Head Important Notes No Guide Hole (Solid Workpiece Hole Drilling) With Guide Hole Flat Finishing of Hole Bottom J Drilling Application Guide Holes Solid Special Flat Surface Non-Flat Surface Indexable 1.5D Holder ○ ○ (Guide Hole Not Required) ○ Reamer 3D to 12D Holder × × ○ Brazed Others ■ Recommended Cutting Conditions (MFS Type) vc: Cutting Speed (m/min) f: Feed Rate (mm/rev) Work Material Soft Steel General Steel Hardened Steel Stainless Steel Gray Cast Iron Ductile Cast Iron Aluminum Alloy* (Up to 250HB) (250 to 320HB) (45HRC) (Up to 200HB) Drill Diameter Cutting Min. - Optimum - Max.

The depth is measured from the highest point of the hole when drilling on inclined surfaces. The recommended cutting conditions above are for drilling on flat horizontal surfaces. (*) Inquire about drills specifically Adjust the feed rate according to the inclination angle when drilling on an inclined surface. Set the feed rate at 70% or lower when the inclination angle is 30° or less. for aluminum alloy. Set the feed rate at 50% or lower when the inclination angle is larger than 30°. This product is a drilling tool. Do not use it for traverse or helical milling. J76
