Star Cutter

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

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

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.

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

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.

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).

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

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) 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.

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.

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.

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.

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.

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.

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

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 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 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°.

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.

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

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.

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.

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.

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

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.

Special Form cutters are manufactured in a wide range of configurations, including straight and spiral gash designs for cutting gear racks; serration form cutters for chuck jaws and steering gear segments as well as a wide variety of special form relieved cutters for producing items such as pliers, clipper guides, concave and convex form, and tool bits. The drives range from simple keyway bores to complex hubs and shanks.

Available in shell type or shank type, multiple thread milling cutters are form relieved and can be supplied with special thread forms.

Saw blade milling cutters for hack, band, or circular saw blades come in single or variable pitch, straight or tapered outside diameters, single cutters up to 13.5” long or interlocked sets, accurate unground or hard finished.

Shank hobs are designed for today’s high cutting velocity tools with extra long active cutting lengths. They are designed for most machines in today’s hobbing machine market, including shank styles to fit the old Barber Colman hobbing machines to cut small diameter worm gear applications.

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

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.

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.
