Kennametal 7093847 Vbmt Turning Insert Carbide Altin

Product Description

The KENNAMETAL 7093847 is a VBMT-style carbide turning insert designed for precision lathe and turning center operations. It features a 35-degree diamond insert shape with a 5-degree relief angle and a 0.008-inch (0.20 mm) corner radius for fine-detail finishing and light roughing passes. The insert is coated with AlTiN (aluminum titanium nitride) and manufactured to the KCU10B grade, providing strong wear resistance and thermal stability at elevated cutting speeds. The LF chip breaker geometry controls chip flow during turning operations. Two cutting edges are available per insert. This insert is installed by CNC machinists and tool-and-die technicians working with ferrous and non-ferrous workpiece materials.

The 7093847 suits precision turning applications on CNC lathes and manual engine lathes where a sharp, low-included-angle diamond insert is required. The VBMT style with neutral hand orientation makes it adaptable to standard right-hand and some left-hand toolholders. The 0.008-inch corner radius makes it well suited for finishing passes requiring tight radius control and fine surface finish. It is commonly used in production turning of shafts, pins, and profiled components where dimensional accuracy and edge consistency are priorities.

Key Features

• VBMT insert style with 35-degree diamond (V-shape) geometry for low cutting forces and detailed profiling
• AlTiN coating on KCU10B carbide grade for elevated wear resistance and thermal performance
• 0.008-inch (0.20 mm) corner radius for fine finishing and tight-tolerance turning
• 5-degree relief angle (clearance code B) reduces flank wear during light-to-moderate cutting passes
• LF chip breaker geometry for controlled chip formation during finishing operations
• Neutral hand orientation for flexible toolholder compatibility

Compatibility

Designed as an OEM-style replacement turning insert for VBMT-compatible toolholders accepting a size 3305 insert with 3/16-inch thickness and 3/16-inch width.

Installation Notes

Turning inserts are seated and secured by a licensed machinist or CNC technician. Before changing inserts, disengage the spindle drive and bring the machine to a complete stop. Use the appropriate torx or hex key to torque the clamp screw according to the toolholder manufacturer specifications. Inspect the insert pocket for chips or debris before seating the new insert to ensure proper contact and runout accuracy.
