Part Material : Grey Cast Iron, Tool: Conventional tool , MDW 1250HX5 (ø12.5mm 5D) Cutting Conditions : v c =328 SFM, f =0.024 IPR, H =1.979”, internal coolant supply (water soluble)
Longer Tool Life High-feed cutting reduces margin wear and extends tool life.
→ Maintains replacement frequency (cutting time) and enables high ef ciency drilling.
