DrillingSolidIndexableIndexableHead TypeInsert TypeReamersBrazedOthers Bore Diameter (mm) SEC-MultiDrills SMD Type MFS Type Ideal for drilling and burr control on non-flat surfaces DEX Coat High rigidity with RS thinning ● Suited to various types of drilling thanks to a point angle of 180° Can be used for high-ef ciency spot facing, drilling on non-horizontal surfaces such as inclined and cylindrical surfaces, and interrupted drilling. Also reduces burrs at the hole exit. ● Improves machining stability Excellent entry Achieves high rigidity by employing RS THINNING, which ensures thick web at the bottom. with sharp edge J Strong peripheral edge ■ Performance Comparison of Hole Diameter Accuracy Comparison of Cutting Force 14.05 max MFS Type ▲ (▲) ave 14.04 min 14.03 14.02 14.01 Competitor's 14.00 Product 13.99 13.98 MFS Type Competitor's Product Tool : S MDH 140S + SMDT 1400MFS Work Material : S 50C Cutting Conditions : v c=100mm/min, f =0.15mm/rev, Hole depth 21mm, Wet ■ Precautions when Using MFS Type Heads No guide hole (final hole only) With guide hole Flat finishing of hole bottom Application Guide Holes Flat surface Non- at surface 1.5D holder ○ ○ (guide hole not needed) ○ 3D to 12D holders × × ○ ■ Recommended Cutting Conditions (MFS Type)  (vc: Cutting speed (m/min), f: Feed rate (mm/rev)) Work Material Mild Steel(up to 250HB)General Steel Hardened Steel Stainless Steel(250 to 320HB)(45HRC)(up to 200HB)Gray Cast IronDuctile Cast Iron Aluminum Alloy* Dia.

The depth is measured from the highest point of the hole when drilling in inclined surfaces.The recommended cutting conditions are those for drilling in flat horizontal surfaces.*( ) Inquire if you require drill heads dedicated for aluminum alloy. Adjust the feed rate according to the inclination angle when drilling in an inclined surface. Set the feed rate at 70% or lower when the inclination angle is 30° or less. 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 cutting or helical milling. J104
