Solid Carbide Core Drills

Overview

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.

Carbide Drills & Reamers

• Multi Diameter Cavity Machining Tools

  

  Star SU has perfected a line of cavity/porting tools that will allow cuts from either a solid or cast core casting condition. In many cases, these multi-step tools will allow cavity machining in one pass or shot.

• Solid Carbide Drills

  

  Star SU's specially designed, solid carbide drills are available as straight or helical drills, single or multiple diameters drills, single or multiple-flute design, diameter range starting from 0.1875" (4.76 mm).

  Star SU has special design and build core drills that are ideal for machining aluminum, ductil, nodular, and compacted graphite irons (CJI).

• Reamers

  

  Star SU reamers are made in both multiple flute and multi-diameter types. Based on the overall length of the tool required to machine your feature, we can manufacture a solid carbide reamer or braze a solid carbide reamer head to a tubular steel body.

• Super Round Tool (SRT)

  

  Super Round Tool (SRT) Lead InThe SRT is an original Star Cutter Company design and build product that offers a unique, patented design that combines two tools into one — multiple straight flutes for consistent location and multiple helical flutes to ensure roundness and finish.

• Valve Guide Reamers

  

  Star SU valve guide reamers utilize pressurized coolant to force chips ahead of the tool to produce ultra-smooth, ultraprecise holes. They produce holes to tolerance of 0.0005" (0.13 mm) and less in steel, cast iron, compacted graphite iron, nodular iron, aluminum, bronze and exotic materials.
