Kennametal 4175857 Grooving Insert KCU10 Solid Carbide Altin

Product Description

The KENNAMETAL 4175857 is a solid carbide grooving insert designed for external grooving and turning operations on CNC lathes and turning centers. This insert features an AlTiN (aluminum titanium nitride) coating applied via PVD process, which improves wear resistance and thermal performance during high-speed cutting. It carries the manufacturer grade KCU10 and belongs to the Top Notch series, a widely used platform in production turning environments. The insert has a left-hand cutting orientation, a 2.39 mm cutting width, and a maximum depth of cut of 2.79 mm. Machinists and CNC operators working in job shops or production facilities install this type of insert into compatible Top Notch toolholders.

This insert is suited for grooving applications in medium to hard workpiece materials, consistent with the C3 and C4 material grade ratings. The KCU10 carbide grade with AlTiN PVD coating is appropriate for cutting steel and alloy materials where heat resistance and edge durability are priorities. It fits turning center setups requiring precise groove width control in the 2.00 mm to 3.00 mm depth-of-cut range. The K chip breaker geometry assists with chip control in moderate feed-rate applications. This insert is sold individually but carries a minimum order quantity of 5 units per order.

Key Features

• 2.39 mm cutting width with a maximum depth of cut of 2.79 mm
• K chip breaker geometry for improved chip control at moderate feed rates
• Clamp-style insert holding method compatible with Top Notch series toolholders
• 55-degree included angle and 0.19 mm corner radius for defined groove geometry

Compatibility

This insert belongs to the Top Notch series and is designed for use with Top Notch series grooving toolholders that accept NG-style inserts with a 2094 insert size designation. The MSC/Manufacturer cross-reference number for this insert is NG2094R/LK.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician with the machine powered off and the spindle fully stopped before changing inserts. Use the appropriate torx or hex key as specified by the toolholder manufacturer when seating the clamp to secure the insert. Inspect the toolholder pocket for chips or debris before seating a new insert, as contamination affects insert seating and can cause premature edge failure. Follow the cutting parameter recommendations from the toolholder and insert documentation for feed rate and speed settings appropriate to the workpiece material.
