Kennametal 1875161 Dcln Indexable Turning Toolholder

Product Description

The KENNAMETAL 1875161 is a right-hand DCLN-style indexable turning toolholder designed for negative-rake metal cutting operations on CNC and manual lathes. Part of the Kenclamp series, it accepts CN..54. style inserts secured by a clamp-style holding method, providing rigid and repeatable insert positioning. The shank measures 1 inch wide by 1 inch tall, with an overall length of 5 inches and a head length of 1.38 inches. It is installed by machinists and tool-room technicians in production turning and general-purpose OD turning applications where negative-rake geometry is specified.

This toolholder suits OD turning operations on ferrous and non-ferrous workpieces in both job-shop and production environments. The 5-degree lead angle and DCLN geometry make it appropriate for straight turning and light facing passes. The 0.625-inch insert inscribed circle accommodates CN..54. (CN.. 543) inserts, which offer a wide selection of grades and geometries for various material groups. Coolant-through capability is not supported on this holder.

Key Features

• DCLN-style clamp system holds CN..54. inserts securely under cutting loads
• Negative rake geometry reduces cutting forces on rigid setups and harder workpiece materials
• 1 x 1 inch square shank fits standard lathe tool posts and turrets accepting that block size
• 5-inch overall length with 1.38-inch head length suits typical OD turning clearance requirements
• Steel construction provides durability in continuous and interrupted cut applications
• Right-hand cut orientation for conventional lathe setups feeding toward the headstock

Compatibility

Designed to accept CN..54. style inserts, specifically CN.. 543 per the complete insert compatibility designation. Manufacturers catalog number DCLNR L165CKC4 may be used as a cross-reference. No additional compatible model or system information was provided in the product data.

Installation Notes

Installation should be performed by a qualified machinist or tool-room technician. Secure the shank fully within the tool post or turret pocket before applying any clamping force, and verify that the cutting edge height is set to centerline before taking a cut. Always power down and lock out the machine spindle before changing inserts or repositioning the toolholder. Follow the machine tool manufacturer torque guidelines for tool post bolts; do not over-torque clamping screws on the insert seat.
