  Star SU provides unparalleled quality for multiple pitched form relieved milling cutters from standard rack forms to asymmetrical shapes. Metric or inch dimensions up to 300mm long. We offer you a high quality, competitive cost and delivery alternative as a manufacturer of Rack Milling Cutters made to your specific manufacturing needs.

Chamfer & Deburring Tools

• Chamfering Tools

  

  Chamfering the flank edges of spur and helical cylindrical gears prevents edge distortion during heat treatment and protects the tooth profile against any nicks that may occur during handling.

• Deburring Tools

  

  A burr which is not removed may break off during use and damage bearings or gears in gearboxes.
  Over-carbonizing may result in too much pressure being exerted on sharp gear lateral surfaces which might then break. A hardened burr may lead to premature wear of tools in subsequent finishing operations. Removal of very sharp burrs reduces the risk of tool handling injuries.

• Chamfer, Deburr & Rolling Tools Combos

  

  Chamfer, deburring and rolling tools are available as combination tools in set of various combinations.

Scudding®

• Scudding®

  

  Star SU has formed an alliance with Profilator to manufacture Scudding® tools for the global market.

Gundrills

• Single Flute Gundrills

  

  The single flute gundrill, with its ability to machine very straight deep holes and hold excellent finishes, was originally developed for gun barrel manufacturing. Today, this drill is designed for deep hole drilling in virtually any material.

• Solid Carbide Single Flute Gundrills

  

  Solid carbide gundrills have a two-piece construction design. The tip and body are a single piece of carbide brazed into the driver/shank and the flute is ground down the length of the head and body. This rigid design has made its way into CNC machining centers and lathes, equipped with high pressure coolant delivery systems.

• Two-Flute Two-Hole Gundrills

  

  Often referred to as the “milled style,” the two-flute two-hole gundrill differs from the double crimp by the rigidity of its body. This rigid body allows for higher feed rates than traditional crimp body style drills.

• Double Jet Gundrills

  

  Star SU, with its years of experience in gundrilling developed a Star original patented Double Jet Gundrill. The most critical interface, in which the carbide is subjected to the most traumas, is during entry/exit of the part and during interruptions of the boring cycle.

• Double Crimp Gundrills

  

  The term double crimp is derived from the process of crimping the same tube used for the single flute gundrill, only crimping it twice, 180 degrees apart. Therefore, with the flute channels on this type of tool being somewhat shallower then the single flute, they limit the type of materials to be drilled by the chip size generated.

• Bi-Tip Gundrills

  

  Similar to the Two-Flute Two-Hole “milled style” product line engineered with a solid steel body, the Bi-Tip has an auger-like helix ground in the body.

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.

• 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.

PCD Tooling

• PCD Precision Reamers

  

  Star SU/Neher designs and builds precision helical and straight flute PCD reamers, available in carbide and steel body monoblock styles. All tools are manufactured specifically to meet custom design requirements.
