Sandvik Coromant 5753134 Grooving Insert TLGP3 1125 Top Lok

Product Description

The SANDVIK COROMANT 5753134 is a solid carbide grooving insert in the Top Lok series, designed for precision grooving and parting operations on CNC lathes and turning centers. It carries an ISO code of TLGP-3047L 1125 and features a dual-layer PVD coating — TiCrAlN over TiAlN — that provides heat resistance and extended edge life in demanding turning applications. The insert is left-hand oriented with a 1.19 mm cutting width, a maximum depth of cut of 1.91 mm, and a neutral rake geometry with a 10-degree rake angle. Machinists and tool setters working in production turning environments install this insert as a replaceable cutting edge in compatible Top Lok toolholders.

This insert is suited for grooving operations on small-diameter workpieces in both production and job-shop turning environments. The TLGP style and size 3 designation make it appropriate for applications requiring tight groove widths and controlled depth of cut, such as snap-ring grooves, undercuts, and parting cuts on steel, stainless, and similar materials. The multi-use designation indicates the insert supports repeated indexing within compatible Top Lok insert seats. It is packaged individually with a minimum order quantity of 10 units.

Key Features

• Solid carbide substrate with PVD-applied TiCrAlN and TiAlN dual-layer coating for thermal and wear resistance
• Left-hand cutting orientation, TLGP insert style, size 3 seat
• 1.19 mm cutting width with a 0.19 mm corner radius for controlled groove profile
• Maximum depth of cut of 1.91 mm; depth range extends up to 2.00 mm depending on setup
• Neutral rake geometry with a 10-degree rake angle reduces cutting forces on difficult materials
• Multi-use insert compatible with Top Lok series toolholding systems

Compatibility

Designed for use with Top Lok series toolholders accepting a size 3 insert seat and TLGP-style inserts. ISO code TLGP-3047L 1125 and manufacturers catalog number TLGP-3047L 1125 should be used to confirm holder compatibility before installation.

Installation Notes

Installation is performed by a qualified machinist or tool setter on a powered-down CNC lathe or turning center with the spindle locked and all energy sources isolated per shop lockout/tagout procedures. Seat the insert fully into the Top Lok pocket and verify clamping torque with the toolholder manufacturer's specifications before cutting. Inspect the insert seat for chips or debris that could affect seating and cause premature edge failure. Do not exceed the specified maximum depth of cut for the insert size.
