Hertel 1001168 Turning Insert VBMT221LF HC210 Carbide Tin

Product Description

The HERTEL 1001168 is a VBMT-style solid carbide turning insert with a TiN (titanium nitride) PVD coating and an HC210 manufacturer grade. It features a 35-degree diamond shape (insert shape code V) with a neutral hand orientation, making it suitable for general-purpose external turning operations. The inscribed circle measures 1/4 inch (0.2500 inches), insert length is 11.07 mm (0.4358 inches), and the corner radius is 1/64 inch (0.0160 inches). This screw-on insert is used by machinists and CNC lathe operators working across a range of workpiece materials. The positive rake geometry and T-style chip breaker help manage chip flow during cuts up to 1.25 mm (0.0492 inches) depth.

This insert is suited for turning operations on stainless steel (M), non-ferrous materials (N), high-temperature alloys (S), and cast iron (K) as secondary workpiece material. It fits standard VBMT screw-on toolholders used in CNC turning centers and manual lathes in both production shop and job shop environments. The HC210 carbide grade with PVD TiN coating provides wear resistance for light-to-medium finishing and semi-finishing passes. Material grades C2 and C4 apply.

Key Features

• Solid carbide construction with PVD TiN coating for wear resistance
• 35-degree diamond insert shape (V) with neutral hand orientation
• 1/4 inch inscribed circle and 1/64 inch corner radius for light-radius finishing work
• Positive rake geometry with T-style chip breaker for controlled chip evacuation
• Screw-on holding method with 5-degree relief angle (clearance code B, tolerance code M)
• Maximum depth of cut: 1.25 mm (0.0492 inches)

Compatibility

Designed for use in standard VBMT screw-on turning toolholders. Compatible with workpiece materials classified as M (stainless steel), N (non-ferrous), S (high-temperature alloys), and K (cast iron) per ISO material group designations. Material grades C2 and C4 apply.

Installation Notes

Installation is performed by machinists using the appropriate VBMT screw-on toolholder and insert screw. Ensure the toolholder pocket and seating surfaces are clean and free of chips before seating the insert. Use a calibrated torque screwdriver to secure the clamp screw to the toolholder manufacturer's specified value. Index or replace the insert when surface finish or tool life indicators show wear at the cutting edge.
