Star SU has special design and build core drills that are ideal for machining aluminum, ductil, nodular, and compacted graphite irons (CJI). Our special engineered designs allow our solid carbide drills to machine either in solid or cored casting conditions. These core drills reduce cycle times, provide constancy in the overall life of the product and machine without much noise compared to an inserted drill. In addition, solid carbide core drills can be re-sharpened many times, keeping the cost per hole competitive.

  • Special design three-fluted core drills available
  • Special design four-fluted core drills available

Special core drills can also serve as excellent pilot tools in gundrilling operations. Depending on the design of the part machined, this type of pilot tool can also have a chamfer added, allowing the core drill to combine two tools into one. These are especially helpful for high interruption cuts where indexible inserted tools have limited performance.
