Hertel 1002811 Lh Mcln Indexable Turning Toolholder

Product Description

The HERTEL 1002811 is a left-hand MCLN-style indexable turning toolholder engineered for negative rake cutting operations on CNC and manual lathes. It features a 1-1/4 inch by 1-1/4 inch square shank and an overall length of 6 inches, providing rigid support for insert-based external turning, facing, and profiling work. This toolholder accepts CN..432 series inserts and is part of the HERTEL Multi-Option series. It is intended for use by machinists and tool-and-die professionals working in production turning environments where consistent insert indexing and secure clamping are required.

This toolholder is suited for external turning applications on metal lathes in both production shop and job shop settings. The left-hand orientation positions the cutting edge for specific approach angles and feed directions that right-hand holders cannot address. Negative rake geometry distributes cutting forces across the insert edge, making it appropriate for interrupted cuts and harder workpiece materials where edge strength is a priority. It is a fixed, non-adjustable, single-purpose holder with no multi-use capability.

Key Features

• Left-hand (LH) MCLN toolholder style for specific approach and feed direction requirements
• Negative rake geometry for improved insert edge strength and durability in demanding cuts
• Accepts CN..432 indexable insert style for broad insert availability
• 1-1/4 inch by 1-1/4 inch square shank for rigid machine tool interface
• 6 inch overall length providing reach and stability in standard lathe turrets
• Part of the Multi-Option series for consistent fitment across compatible tooling systems

Compatibility

Designed to accept CN..432 series indexable inserts. Verify turret pocket dimensions and insert grade selection against workpiece material before installation.

Installation Notes

Installation should be performed by a qualified machinist following shop safety procedures. Ensure the lathe spindle is fully stopped and locked out before mounting or removing toolholders from the turret. Use appropriate torque tools to secure the shank in the tool block or turret pocket without over-clamping. Confirm insert seating and clamp screw torque per the insert manufacturer's guidelines before resuming cuts.
