Core offering

Jinyong is a specialized manufacturer of precision gear cutting tools, producing broach cutters, pinion cutters, milling cutters, master gears, and hobs for industrial customers. The company serves automotive transmission factories and general industrial manufacturers with custom-designed gear tooling, operating in-house manufacturing using advanced German and Japanese machine tools and maintaining an in-house research institute for ongoing development.

Product overview

Jinyong is a precision gear cutting tool manufacturer established in 1994, specializing in custom-made cutting tools for gear applications. The product portfolio includes five main product lines: Broach Cutters (including round and surface broaches for spline, key, clutch, sleeve, steering rack, and disc brake applications), Pinion Cutters (in disk, bell, and shank types), Milling Cutters (involute, bevel, rack, and worm cutters), Master Gears (precision measurement tools to DIN4/JIS 0 grade), and Hobs (various types for gear cutting). The company operates an in-house research institute and serves automotive and aerospace industries with custom-designed tools.

Products and services

• Broach Cutter (브로치 커터) A cutting tool that machines the inner or outer surface of workpieces using roughing and finishing blades in sequential order. Features high-precision processing in minimal time, simplified machining of complex axial shapes, and stable dimensional accuracy. Used by industrial gear manufacturers and automotive suppliers.
• Involute Spline Broach (인볼루트 스플라인) Broach cutter for machining involute spline profiles, widely used in power transmission gear applications.
• Sleeve Gear Broach (슬리브 기어) Internal gear broach for automobile transmissions, used in sets of two for rough machining, pre-rolling, and finish machining of sleeve gears.
• Double Key Broach (각형 2 스플라인) Double-key broach with front/rear chip pockets, offering high precision and productivity for key way machining.
• Clutch Hub Broach (클러치 허브) Internal gear broach for automobile transmissions that machines special tooth form involute gears with high efficiency, used in clutch hub manufacturing.
• Steering Rack Bar Broach (스티어링 랙바) Broach for machining steering rack bars in automobile steering systems, with optimized design for unequal pitch and crowning.
• Disc Brake Caliper Broach (디스크 브레이크) Broach for machining disc brake caliper slide groove surfaces in automobile braking systems.
• Key Hole Broach (키이 홈) Cutting tool for machining key slots in product bores, offering higher precision and faster processing than milling or shaping.
• Pinion Cutter (피니언 커터) Gear cutting tool with cutting edges on gear tooth profiles, used on gear shapers for external and internal gear generation using EPY-CYCLOID and HYPER-CYCLOID methods. Available in Disk, Bell, and Shank configurations.
• Milling Cutter (밀링 커터) Special milling cutters including involute cutters for gear machining, bevel cutters for bevel gears, rack cutters, worm cutters for worm shaft roughing, and other custom designs.
• Master Gear (마스터 기어) High-precision gear tool for checking gears in aerospace and automotive industries. Manufactured to DIN4/JIS 0 grade standards with M1, M0, M00 accuracy levels. Features lead and profile crowning options.
• ROB (Reverse Taper Involute Tool) Tool for machining inverse taper involute curves on manual transmission sleeve inner gears using plastic deformation. Available in assembled and integral types.
• Hob (호브) Gear cutting tool shaped like a screw with flutes containing cutting edges for generating gear teeth. Types include carbide hobs, shank hobs, involute special hobs, parallel side spline hobs, timing hobs, standard gear hobs, and roller chain sprocket hobs.

Broad incumbents

• Kennametal: US-based manufacturer of metal cutting tools, including gear hobs and milling cutters, serving automotive and industrial markets. Competes with Jinyong in select gear cutting product lines but at a much larger, multi-category scale.
• Sandvik Coromant: Global leader in metal cutting tools within Sandvik's machining solutions division. Overlaps with Jinyong through its gear cutting tool offering but operates as a much broader, diversified industrial cutting tool supplier across all machining applications.
• Nachi-Fujikoshi: Japanese manufacturer of cutting tools, bearings, and machine tools, including broaches and hobs. Comparable to Jinyong in gear cutting tool offerings but at much larger industrial conglomerate scale with diversified end markets.
• OSG Corporation: Japanese manufacturer of taps, end mills, drills, and gear cutting tools. Competitor to Jinyong in gear cutting, especially across Asian automotive supply chains, but with a much broader product portfolio and global footprint.
• Mitsubishi Materials: Japanese conglomerate offering carbide cutting tools including gear hobs and broaches. Comparable in gear cutting tooling technology while operating a far larger diversified materials and tooling portfolio.

Direct peers

• Star SU: US-based manufacturer of gear cutting tools (hobs, broaches, shaper cutters) and gear grinding machines. Direct comparable to Jinyong across the gear cutting tool portfolio, serving the same automotive transmission customer base.
• Gleason Corporation: US-headquartered global leader in gear manufacturing machines and tooling, including hobs, broaches, and master gears. Directly competes with Jinyong in precision gear cutting tooling for automotive and aerospace customers, and Jinyong already uses Gleason Pfauter grinding equipment.
• Samputensili: Italian manufacturer of gear cutting tools, gear grinding machines, and power skiving tools, part of the Sampensione group. Highly comparable to Jinyong in product scope (hobs, broaches, master gears, shaper cutters) and customer segments (automotive transmissions, aerospace).
• Klingelnberg: German manufacturer of gear cutting tools, gear grinding machines, and gear metrology systems. Closely overlaps with Jinyong's precision gear tooling portfolio, including high-end cylindrical and bevel gear cutting tools used in drivetrain applications.

Regional players

• YG-1: South Korean cutting tool manufacturer producing milling cutters, drills, taps, and gear-related tooling. Most directly comparable Korean peer to Jinyong in terms of geographic base, though with a much broader catalog and larger scale.
