Kennametal 1871036 Turning Insert VBMT3305LF KC5010

Product Description

The KENNAMETAL 1871036 is a solid carbide turning insert with a TiAlN PVD coating, designed for precision finishing and light machining on CNC lathes and turning centers. It conforms to ANSI designation VBMT3305LF and ISO designation VBMT160402. The insert features a 35-degree diamond (rhombic) shape, a neutral hand orientation, a 0.0079 inch corner radius, and a 3/8 inch inscribed circle. The KC5010 grade delivers high wear resistance across a range of metalcutting applications. This insert is held in place via a screw-on clamping method and is installed by machinists and CNC setup technicians on qualified toolholders.

The KENNAMETAL 1871036 is suited for turning, facing, boring, back turning, and back boring operations. Primary workpiece materials include steel, stainless steel, superalloys, and titanium, with secondary suitability for nonferrous materials. The LF chip breaker geometry is optimized for finishing and light machining cuts, making this insert appropriate for tight-tolerance surface finish requirements on both manual and CNC turning equipment in job shop and production environments. The positive rake and positive side clearance geometry reduce cutting forces and heat generation during light depth-of-cut passes.

Key Features

• ANSI code VBMT3305LF / ISO code VBMT160402 for direct cross-reference and toolholder matching
• KC5010 grade with TiAlN PVD coating for high wear resistance on steel, stainless steel, and superalloys
• 35-degree diamond insert shape with positive rake and positive side clearance to minimize cutting forces
• LF chip breaker optimized for finishing and light machining applications
• Screw-on holding method for secure, repeatable seating in compatible toolholders
• Two cutting edges per insert; honed cutting edge style for edge integrity on finish passes
• Maximum depth of cut of 0.0492 inches (1.25 mm) per pass

Compatibility

Designed for use in screw-on style VBMT toolholders conforming to ANSI and ISO standards for 3305 and 160402 insert size codes. Verify toolholder pocket geometry, insert size code, and clamping style before installation. No specific brand toolholder models were identified in the product data.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Power down and lock out the machine before changing inserts. Use the correct torque screwdriver or wrench specified by the toolholder manufacturer when seating the screw-on clamp; do not overtighten, as this can crack the carbide insert. Inspect the insert pocket for chips or debris before seating a new insert to ensure proper contact and runout.
