Vargus 53720 Threading Insert 48-16 Tpi Solid Carbide Tialn

Product Description

The VARGUS 53720 is a solid carbide laydown threading insert designed for internal thread cutting operations. It carries a TiAlN coating applied via PVD process, which provides thermal resistance and extended tool life in demanding threading applications. The insert produces a 60-degree partial profile thread and covers a range of 48 to 16 threads per inch, corresponding to a pitch range of 0.50 to 1.50 mm. With a right-hand cutting orientation and a single tooth per side, it is suited for precision internal threading on CNC lathes and turning centers. Machinists and toolroom operators working in metal fabrication, aerospace, and industrial manufacturing are the primary users of this insert.

This insert is used for right-hand internal threading on CNC turning equipment where a partial profile 60-degree thread form is required. The 48 to 16 TPI range makes it applicable across a broad selection of unified and metric-equivalent thread sizes in ferrous and non-ferrous workpiece materials. It is a single-piece, solid carbide insert that fits laydown-style insert holders accepting the 3JIR insert style. The TiAlN finish extends cutting performance in high-speed or dry machining environments where heat generation is a concern.

Key Features

• Solid carbide construction in VCB grade for rigidity and wear resistance in threading operations
• TiAlN coating via PVD process for improved heat resistance and longer tool life
• 60-degree partial profile thread form covering 48 to 16 TPI and 0.50 to 1.50 mm pitch
• Right-hand internal cutting orientation with a 3JIR insert style for laydown toolholders
• 9.53 mm (3/8 inch) inscribed circle and 3.60 mm thickness for consistent seating and indexing
• 0.0500 inch corner radius with one tooth per side for controlled thread form engagement

Compatibility

Designed for use in laydown-style threading toolholders that accept the 3JIR insert style with a 9.53 mm inscribed circle and 3.60 mm insert thickness.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Ensure the machine spindle is fully stopped and the toolholder is secured before seating or indexing the insert. Use the appropriate torque wrench and insert screw specified by the toolholder manufacturer to clamp the insert correctly - do not overtighten by hand. Verify insert seating and thread form engagement with a test cut and thread gauge before running production.
