High Efficiency Solid Carbide Strong MultiDrill HX Type ■ General Features Strong MultiDrill HX Series is a special drill for cast iron that combines reduced cutting resistance and improved strength to achieve stable, high efficiency drilling of cast iron. Significantly improved chip control and evacuation ■ Characteristics and Applications ●High efficiency drilling of cast iron Thick web and special double margin design ensure stable behavior even in high-efficiency drilling. Furthermore, RX THINNING significantly reduces cutting resistance, ensuring more stable and highly-efficient drilling. Enables high-efficiency drilling at speeds of over vf=1,000mm/min (for ø10mm diameter). ●Long tool life DEX Coat DEX Coat for drills utilizes nano-coating technology that achieves more than Coating Hardness (GPa) 50 double the tool life of conventional coatings. The guide function is enhanced through optimizing the margin position to prevent drill breakage due to hole bending. 40 TiSiN 30 TiAlN TiCN 20 TiN 0〜 〜 Poor ← Chipping Resistance → Good Low cuting forces Wide chip pocket reduces thrust resistance. ● Conventional Tool ● HX 4,500 4,500 4,000 4,000 J Cutting Force (N) 25% Down 3,000 3,000 Drilling Suitable for 2,000 2,000 low rigid machines 1,000 1,000 0 2.5 3.0 3.5 4.0 4.5 5.0 0 2.5 3.0 3.5 4.0 4.5 5.0 Solid -500 -500 Special Cutting Time (sec) Cutting Time (sec) Indexable Work Material : FC250  Tool : Conventional Tool, MDW1250HX5（ø12.5mm 5D） Cutting Conditions : vc=100m/min, f =0.60mm/rev, H=50mm, Internal Coolant (Water Soluble) Reamer Brazed Others High Rigidity Large web thickness and wide land reduces vibration. ● Conventional Tool ● HX 1,000 XY Force x 1,000 XY Force x y y Conventional Tool Reduces cutting vibration 800 800 HX Cutting Force (N) 30% Down 400 400 0 0 -400 -400 -800 -800 -1,000 2.5 3.0 3.5 4.0 4.5 5.0 -1,000 2.5 3.0 3.5 4.0 4.5 5.0 Cutting Time (sec) Cutting Time (sec) Work Material : FC250  Tool : Conventional Tool, MDW1250HX5（ø12.5mm 5D） Cutting Conditions : vc=100m/min, f =0.60mm/rev, H=50mm, Internal Coolant (Water Soluble) J20
