OSG FORMING

OSG Forming is a product line within OSG Corporation, a Japanese manufacturer of cutting tools and threading solutions with a history dating back to 1938. The OSG Forming range specializes in thread-forming taps, also known as roll taps or cold-forming taps, which produce internal threads by displacing material rather than cutting it. This process generates no chips, making it suitable for applications where chip evacuation is problematic, such as blind holes or deep threads. OSG Forming taps are manufactured from powdered metal (PM) high-speed steel, a material choice that provides wear resistance and toughness for extended tool life in production environments. The taps feature a VI coating, a titanium-based coating that reduces friction and improves lubricity, allowing for higher threading speeds and improved surface finish on the formed threads. The product family includes standard and oversized taps in both Unified (UNC/UNF) and Metric thread profiles, with tolerance classes such as H5, H8, H11 for Unified threads and D11, D12, D15 for Metric threads, corresponding to 2B-3B and 6H fit classes respectively. Chamfer styles include bottoming and modified bottoming, enabling threading close to the bottom of blind holes. OSG Forming taps are designed for use in ductile materials such as aluminum, low-carbon steel, stainless steel, copper alloys, and certain plastics, where material flow is favorable. 3G Electric supplies a comprehensive inventory of OSG Forming taps, covering thread sizes from #6-32 UNC to 1"-12 UNF and M12x1.75 to M24x3 Metric, with multiple tolerance and chamfer options. Each SKU is accompanied by detailed datasheets specifying thread dimensions, tolerance class, coating type, and material compatibility, enabling engineers and procurement specialists to select the correct tap for their application. 3G Electric provides global logistics support, ensuring that these precision threading tools are available for maintenance, repair, and production operations worldwide.

Pertanyaan yang Sering Diajukan

Pertanyaan umum tentang OSG FORMING dari 3G Electric.

What materials are OSG Forming thread-forming taps suitable for?

OSG Forming taps are designed for ductile materials that can undergo plastic deformation without fracturing. Suitable materials include aluminum and aluminum alloys, low-carbon and medium-carbon steels, stainless steel (300 series), copper, brass, bronze, and certain thermoplastics. They are not recommended for brittle materials such as cast iron or hardened steels, as these materials lack the ductility required for cold forming.

What do the tolerance designations H8 / 2B-3B mean on OSG Forming taps?

The H8 designation refers to the pitch diameter tolerance of the tap itself, where H indicates a basic size and the number indicates the tolerance range above basic. For Unified threads, H8 corresponds to a pitch diameter that produces internal threads within the 2B-3B fit classes, which are standard for general-purpose and close-tolerance applications respectively. This ensures the formed thread meets the required fit for mating fasteners.

What is the difference between bottoming and modified bottoming chamfer on OSG Forming taps?

A bottoming chamfer has a short lead of 1-2 threads, allowing threading to the bottom of a blind hole with minimal unthreaded length. A modified bottoming chamfer has a slightly longer lead of 2-3 threads, providing a balance between bottoming capability and reduced torque during forming. The choice depends on the depth of the blind hole and the material's formability.

What does the VI coating on OSG Forming taps do?

VI coating is a titanium-based coating applied to the powdered metal substrate of OSG Forming taps. It reduces friction between the tap and workpiece material, lowers torque requirements during thread forming, and improves lubricity. This coating also enhances wear resistance, allowing for higher threading speeds and longer tool life compared to uncoated taps, particularly in abrasive materials like aluminum alloys.

How do I select the correct oversized OSG Forming tap for a specific thread fit?

Oversized OSG Forming taps are designated with higher tolerance numbers, such as H11 for Unified or D12/D15 for Metric threads. These taps produce internal threads with larger pitch diameters, used when the mating fastener is oversized or when a specific fit class (e.g., 3B for Unified) requires a tighter tolerance. Refer to the datasheet for the tap's tolerance class and compare it to the required thread fit specification for your application.
