Star Cutter, world leader in the cutting tool industry

Star Cutter Company was founded in 1927 by Howard B. Lawton and Frank Burgess. The company was started in a leased portion of a building on Epworth Boulevard in Detroit, Michigan. During this first year of operation Star Cutter Company employed ten employees. The main customers in 1927 were Chrysler and Chevrolet Gear and Axle.

Star Cutter Company has developed into a world leader in the cutting tool industry with over 500 employees working in six manufacturing facilities within five manufacturing divisions. Each manufacturing facility specializes in producing a specific type of product or service: solid carbide cutting tools, carbide blanks and preforms, gundrills, gear cutting tools, and 5-axis CNC tool and cutter grinding machines.

Headquartered in Farmington Hills, MI, the Star Cutter Company partners with Star SU LLC for marketing, sales, and service of its products in North America, South America, Europe and the Far East.

Gundrills

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.

Gundrills

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.

Gundrills

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 0.1875″ (4.76 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

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.

Gundrills

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.

Gundrills

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.

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.

Gundrills

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.

Involute Gear Hobs

Involute Spline Hobs

Involute Spline Hobs have straight sides teeth like a gear hob, and are usually of stub tooth depth. They are made in single or multiple thread designs, with diametral pitches ranged from 2.5/5 to 128/256 and pressure angles of 30°, 37.5°, or 45°.

Involute Gear Hobs

Multiple Thread Involute Hobs

These hobs are designed to increase productivity of the hobbing process. Advancements in hob manufacturing has improved the quality to allow finish hobbing with a multiple thread hob. Depending on the lead angle, they will be either straight or spiral gashed.

Milling Cutters

Single and Duplex Milling Cutters

Single and duplex milling cutters are available for most tooth forms from standard involutes and sprockets to special splines and worm cutters.

Involute Gear Hobs

Single Thread Involute Hobs

Single Thread Involute Hobs use straight angled sides for generating gears for maximum accuracy on gear hobbing machines. They are normally specified for processes where no subsequent tooth finishing operations are required, or where improved accuracy before tooth shaving operations is required.

Involute Gear Hobs

Worm Gear Hobs

Worm Gear Hobs are part of specific tools that match the worm shaft with sharpening allowance. This plunge cutting tool is manufactured in shell or shank designs with straight or spiral gash. Lead angles up to 45° are available.

Involute Gear Hobs

Solid Carbide Hobs

Solid carbide hobs can be used in shell or shank design to cut gears with or without coolant, and are available in shell style with keyway or end drives, and various shank designs to fit most hobbing machines. Both “K” and “P” grade material is offered depending on application.

Non-Involute Gear Hobs

Sprocket Hobs

Sprocket Hobs produce accurate finishes and produce the tooth form at one depth. These hobs are available in both single- and multiple-thread designs.

Special Drive Hobs can be designed and manufactured for any special requirement – from OD and face clamping to clutch key ways with special hubs.

Non-Involute Gear Hobs

Straight Key Spline Hobs

Straight or tapered key spline hobs have specially curved tooth forms and are made in single and multiple thread types. They are used to produce at only one depth of cut.

Non-Involute Gear Hobs

Special Form Hobs

Special form hobs are produced for a wide variety of tooth forms such as square shafts, as well as conjugate forms for pump gear that transmit motion. Generally, these special hobs generate the correct tooth form at only one depth, so accuracy is critical.
