Tungaloy has introduced its DoQuad-Mill, a face-milling cutter that is designed to address interference between the tool and workpiece.

Standard face-milling tools generally prevent end users machining close to walls or fixture clamps due to inclined entry angles, says Tungaloy. In contrast, the DoQuad-Mill has been developed with a near 90° entry angle that ensures the cutter is interference-free and therefore capable of face milling extremely close to walls and other features.
The double-sided square insert incorporates a concave cutting edge profile with a large inclination angle. This design improves swarf evacuation and generates barrel-shaped chips, a feature that prevents swarf re-cutting. The inserts incorporate a large rake angle that generates low cutting forces and a smooth cutting action, thus reducing stress and force on both the machine spindle and cutting tool. This capability makes the cutter suitable for customers operating low-powered machine tools, or working with low rigidity or weak fixture settings.
DoQuad-Mill offers cutter diameters ranging from 50 to 100 mm diameter in either standard or close-pitch insert designation. The standard pitch variant is designed to ensure chatter-free milling, whereas the close-pitch cutter is suited to applications where high-feed and high-speed machining is essential. DoQuad-Mill inserts are available with corner radii of 0.8, 1.2 and 2.0 mm. For precision machining applications that require high-quality surface finishes, a wiper insert is also offered.
The DoQuad-Mill is available with a selection of insert grades and coatings to cater for the machining of various material types. This choice includes the AH3135 PVD grade, which has a high fracture resistance, making it the company’s first choice grade for machining steel and stainless steel.
