Tungaloy 6802776 Turning Insert DCGT070201FRJ10 J740

Product Description

The TUNGALOY 6802776 is a solid carbide turning insert with ISO designation DCGT070201FRJ10 and manufacturer grade J740. It features a 55-degree diamond (D-style) insert shape with a positive rake angle of 30 degrees and a sharp cutting edge. The insert carries a TiN coating applied by PVD process, offering enhanced wear resistance on the cutting edge. The corner radius measures 0.0039 inches and the inscribed circle diameter is 0.25 inches. Screw-type insert holding secures it in compatible toolholders. This insert is suited for turning, facing, boring, back turning, and back boring operations performed by machinists and tool-and-die professionals.

This insert is intended for use on steel and stainless steel workpieces, corresponding to ISO material groups P and M. Its sharp edge geometry and positive rake make it particularly effective in light finishing and semi-finishing cuts where surface quality and dimensional accuracy are priorities. The J10 chipbreaker geometry manages chips across a range of feed rates and depths. Maximum depth of cut is 5.00 mm (0.1969 inches). The right-hand configuration suits standard right-hand toolholder setups on CNC lathes and manual turning centers.

Key Features

• 55-degree diamond insert shape (D) with positive rake for reduced cutting forces on steel and stainless steel
• TiN coating via PVD process for surface hardness and wear resistance without compromising edge sharpness
• Sharp cutting edge style with J10 chipbreaker for controlled chip formation in finishing applications
• Corner radius of 0.0039 inches for tight-tolerance and fine-finish turning
• Screw-mount clamping method compatible with Series DCGTR-J10 toolholders
• Two cutting edges per insert; right-hand orientation; multi-use across turning, facing, boring, and back boring

Compatibility

Designed for use with Series DCGTR-J10 toolholders. Compatible with ANSI and ISO standard tooling systems accepting DCGT-style inserts with a 0.25-inch inscribed circle. Intended for machining steel and stainless steel workpieces (ISO P and M material groups).

Installation Notes

Installation is performed by qualified machinists following standard CNC or manual lathe tooling procedures. Power down and lock out the machine spindle before seating or replacing the insert. Secure the insert with the appropriate torx or hex key screw to the manufacturer-specified clamping method for the toolholder series. Inspect the insert seat and clamping screw for wear or debris before each insert change to maintain accurate positioning and safe operation.
