Sandvik Coromant 5846609 Threading Insert Carbide Tialn

Product Description

The SANDVIK COROMANT 5846609 is a carbide threading insert in the Top Lok series, designed for cutting internal and external threads across a pitch range of 1.25 to 6.25 mm (4 to 20 TPI). It carries a TiAlN finish applied via PVD coating, which supports wear resistance in demanding threading operations. The insert is left-hand orientation, conforms to a 60-degree V thread standard, and is identified by ISO code TLTP-4L 1125. With a width of cutting tip measuring 0.255 inches (6.48 mm) and a corner radius of 0.004 inches (0.10 mm), it is suited to precision threading on CNC lathes and turning centers. Machinists, toolroom operators, and CNC programmers working in metalworking environments are the primary users.

This insert is intended for threading applications on both internal and external workpiece features. The 60-degree included angle makes it compatible with unified and metric V-thread forms commonly encountered in general machining, toolroom work, and production turning. The broad pitch range of 1.25 to 6.25 mm (4 to 20 TPI) gives this insert versatility across coarse and fine thread families. It is sized for Top Lok toolholders and is appropriate for use on CNC turning centers and manual lathes where left-hand threading inserts are specified.

Key Features

• Covers 1.25 to 6.25 mm pitch range and 4 to 20 TPI in a single insert
• Left-hand cutting orientation for left-hand thread production
• 60-degree V thread form for unified and metric thread standards
• Top Lok series interface for secure insert seating in compatible toolholders
• Cutting tip width of 0.255 inches (6.48 mm) with a 0.004-inch corner radius for precise thread form

Compatibility

Designed for use with Top Lok series threading toolholders that accept TLTP-style inserts. Compatible with both internal and external threading applications where a left-hand, 60-degree V-form insert is specified.

Installation Notes

Threading inserts of this type are installed and replaced by qualified machinists or CNC toolroom technicians. Power down and lock out the machine spindle before changing inserts. Use the appropriate torx or hex key as specified by the toolholder manufacturer when seating the insert clamp screw. Handle carbide inserts with care to avoid chipping the cutting edge prior to use.
