Solid Carbide Core Drills

Star SU manufactures custom design and build core drills that are ideal for machining aluminum, ductile, nodular, and compacted graphite irons (CGI). These engineered designs allow our solid carbide drills to machine from solid or cored casting conditions.  The core drill is designed to correct imperfections in the casting for finishing operations.

These core drills reduce cycle times, and provide consistency in the overall life of the product, and machine with reduced harmonics compared to an inserted drill. In addition, solid carbide core drills can be re-sharpened many times, keeping the cost per hole competitive.

Special core drills can also serve as excellent pilot tools in gundrilling operations. The pilot tool can also have a chamfer added, allowing the core drill to combine two tools into one. These are especially helpful for highly interrupted cuts where indexable or insert drills experience performance difficulties.
