Cutting Tools from Star Cutter

Gear Cutting Tools

Scudding® Cutters

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


Solid Carbide Twist Drills

Solid Carbide Twist Drills are available in lengths up to 30x diameter and to custom lengths, and are reversed engineered for your specific application.


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.


Rifle Buttons/Push & Pull Reamers

Star high precision rifle buttons and push & pull reamers are made to your specific requirements.

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.

Carbide Drills & Reamers

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 0.1575″ (4.00 mm).

Carbide Drills & Reamers

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).

Carbide Drills & 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.

Carbide Drills & Reamers

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.

Carbide Drills & Reamers

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″ (0.013 mm) and less in steel, cast iron, compacted graphite iron, nodular iron, aluminum, bronze and exotic materials.


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.


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.

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.

Gear Cutting Tools

Master Gears and Plug Gauges

We offer wide range of precision tools for measurement, setting, calibration and correction. All checking and setting masters are fully tested on CNC inspection equipment and are delivered with a certificate of conformity.

Gear Cutting Tools

Gear Shaper Cutters

A wide variety of shaping tools for virtually every application features gear shaper cutters from Fellows, Samputensili, and Star SU.


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.
