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.

Star Cutter

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.

Star Cutter

Rifle Buttons/Push & Pull Reamers

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

Star Cutter

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.

Star Cutter

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.

Star Cutter

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.

Star Cutter

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.

Star Cutter

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.

Star Cutter

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).

Star Cutter

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).

Star Cutter


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.

Star Cutter

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.

Star Cutter

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.
