Valve Guide Reamers

Overview

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.

Ideally adapted to the sizing and enlarging of previously drilled or cored holes, Star SU valve guide reamers provide higher penetration rates and closer size tolerance.

Star SU valve guide reamer diameters start at .1875" (4.76 mm). Cutting feeds and speeds are recommended based on the design of the product and the part requirements.

Star SU reamers are made in both multiple flute and multi-diameter types. They can have solid carbide heads brazed to a tubular steel body in sizes up to 2.0" diameter and with brazed inserts in 2.0" to 4.0" diameter ranges.

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).

• Solid Carbide Core Drills

  

  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.
