SUPER TOOL

SUPER TOOL is a Japanese cutting-tool brand that has been manufacturing reamers, drills, and related precision tooling for industrial machining since the mid-20th century. The brand is known for its carbide-tipped and solid-carbide reamer lines, which are used in production machining, tool and die making, and maintenance operations where hole sizing and surface finish must be held to tight tolerances. SUPER TOOL's product range includes chucking reamers, shell reamers, dowel pin reamers, and taper reamers, with straight-flute and spiral-flute geometries available in inch and metric sizes. The cutting edges are typically carbide-tipped or solid carbide, depending on the model, and the tool bodies are ground to standard shank diameters for use in drill presses, lathes, and CNC machining centers. 3G Electric supplies SUPER TOOL reamers and related tooling to industrial buyers worldwide. The catalog includes straight-flute carbide-tipped chucking reamers in diameters from approximately 0.227 in to 0.6945 in, with additional sizes and styles available on request. These reamers are intended for enlarging and finishing drilled holes in ferrous and non-ferrous metals, and they are commonly specified where a drilled hole must be brought to an exact diameter with a smooth internal surface. The straight-flute design is suited to through-hole and blind-hole reaming in materials that produce short chips, while carbide tips provide wear resistance compared to high-speed steel tools. 3G Electric supports the SUPER TOOL line by maintaining inventory of standard sizes, providing specification data such as diameter, flute type, and manufacturer part number, and sourcing non-stock items through the brand's distribution network. Buyers can request quotes for specific diameters, quantities, and delivery requirements. The product data supplied by 3G Electric includes inch dimensions and MPNs, allowing maintenance and procurement teams to match tools to existing drawings or replace worn reamers without ambiguity. For plant engineers and maintenance managers, SUPER TOOL reamers are a practical choice when a hole must be sized after drilling or when a worn hole needs to be restored to nominal diameter. The carbide-tipped construction is intended for use in materials that are abrasive or that tend to work-harden, and the straight-flute geometry helps control chip evacuation in shorter-hole applications. 3G Electric's role is to make these tools available globally, with the technical data needed to select the correct reamer for a given hole size and material. The brand's focus on reaming and hole-finishing tools means that the catalog is deep in that category, with multiple diameters and flute configurations to cover common inch and metric hole sizes. 3G Electric does not manufacture SUPER TOOL products; it distributes them and provides application support based on published specifications. For buyers who need a specific reamer diameter or a non-standard shank, 3G Electric can check availability and lead time. The combination of SUPER TOOL's tooling and 3G Electric's global logistics gives maintenance and production teams a way to source precision reamers without being limited to a single region.

Frequently asked questions

Common questions about SUPER TOOL from 3G Electric.

What is the difference between a SUPER TOOL straight-flute chucking reamer and a spiral-flute reamer?

SUPER TOOL straight-flute chucking reamers have straight cutting edges along the flutes, which is a common choice for through holes and for materials that produce short, broken chips. Spiral-flute reamers have helical flutes that help evacuate chips in blind holes or in materials that produce stringy chips. The straight-flute design is generally simpler to regrind and is often used in general machining and maintenance work. The correct choice depends on hole type, material, and chip behavior. 3G Electric lists straight-flute carbide-tipped chucking reamers in its SUPER TOOL catalog, and other flute styles can be sourced on request.

What diameter range of SUPER TOOL carbide-tipped chucking reamers does 3G Electric stock?

3G Electric's SUPER TOOL catalog includes straight-flute carbide-tipped chucking reamers with inch diameters from about 0.227 in to 0.6945 in. Examples include 0.227 in (MPN 56552270), 0.2295 in (MPN 56552295), 0.2645 in (MPN 56552645), 0.3255 in (MPN 56553255), 0.4844 in (MPN 55231), 0.556 in (MPN 56555560), 0.645 in (MPN 56556450), and 0.6945 in (MPN 56556945). Additional sizes and styles, including shell reamers and dowel pin reamers, can be quoted on request. Buyers should specify the required diameter, flute type, and shank size when requesting a quote.

Are SUPER TOOL reamers suitable for reaming stainless steel or other work-hardening materials?

SUPER TOOL carbide-tipped reamers are often selected for work-hardening materials because the carbide cutting edges resist wear better than high-speed steel. However, success depends on correct speeds and feeds, rigid setup, and adequate coolant. Reaming stainless steel typically requires lower surface speeds and positive feed to avoid rubbing and work hardening. The straight-flute design can be used in through holes where chips clear easily. For blind holes or difficult chip evacuation, a spiral-flute reamer may be more appropriate. 3G Electric can provide the published diameter and MPN data for SUPER TOOL reamers, but the user should confirm the tool is suited to the specific material and operation.

How do I identify the correct replacement for a worn SUPER TOOL chucking reamer?

To identify a replacement, note the reamer's diameter, flute type, and manufacturer part number (MPN). SUPER TOOL reamers are marked with the size and MPN, and 3G Electric's catalog lists these details for each item. For example, a 0.4844 in straight-flute carbide-tipped chucking reamer corresponds to MPN 55231. If the original marking is worn, measure the reamer's cutting diameter with a micrometer and confirm the flute geometry. The shank diameter and overall length should also match the original tool. 3G Electric can cross-reference the MPN or dimensions to the current SUPER TOOL catalog and provide a quote for the replacement.

What tolerances can be expected from SUPER TOOL carbide-tipped chucking reamers?

SUPER TOOL reamers are manufactured to produce holes within the tolerance range typical for reaming operations, which is generally tighter than drilling. The exact tolerance depends on the reamer's diameter, the material being cut, the machine condition, and the coolant used. Carbide-tipped reamers are intended for precision sizing and finishing of drilled holes, and they remove a small amount of material to bring the hole to the required diameter. For specific tolerance data, refer to the manufacturer's published specifications for the particular reamer model. 3G Electric supplies the MPN and nominal diameter, and buyers should verify the tool meets the drawing requirements for the application.

Does 3G Electric supply SUPER TOOL shell reamers and dowel pin reamers?

Yes. 3G Electric's SUPER TOOL line includes chucking reamers, shell reamers, and dowel pin reamers. Shell reamers are used with an arbor and are common for larger hole diameters where a solid shank reamer would be heavy or expensive. Dowel pin reamers are made for precision fits, such as dowel pin holes in tooling and die work. Availability varies by size and style. Buyers can request a quote for specific SUPER TOOL shell or dowel pin reamer part numbers, and 3G Electric will confirm stock or lead time. The catalog data includes diameter and MPN for the items listed.
