Allied Machine & Engineering will highlight its 4TEX indexable carbide drill designed for applications that include interrupted cuts and/or high-temperature alloys and stainless steels. The flute spacing Carbide Grooving Inserts of the internal cutting edge side is 1.6 times larger than typical IC drills, the company says. The additional flute space, coupled with dual twisted coolant outlets, increases penetration rates with light-duty machines by enhancing coolant flow and chip evacuation in holemaking processes.

4TEX includes four-sided carbide insert geometries that are optimized for wear resistance. Inserts are available in geometry/coating combinations for all ISO materials including steel, stainless steel, high-temperature alloys, nonferrous metals and iron. The company states that the insert shape improves surface finish, hole quality and penetration rates while eliminating issues from chips winding around the tool.

The 4TEX product line is designed for making shallow 2×D, 3×D and 4×D holes in the 0.472" to APKT Insert 1.850" (12- to 47-mm) range. The drills are stocked in both imperial and metric shanks with standard fractional diameters in ½-mm increments up to 26 mm and in 1-mm increments up to 47 mm.

Walter USA has added polycristalline diamond (PCD) grooving inserts to its Walter Cut GX grooving system. These straight-edge (F1) and full-radius (M1) geometries are designed cemented carbide inserts for grooving in aluminum and titanium alloys, enabling high Carbide Milling Inserts cutting speed, lengthening tool life and improving surface quality in grooving, parting and recessing operations. The inserts are said to be ideal for aerospace, medical device and automotive applications.

The wear-resistant WDN10 PCD grade provides high hardness, a low coefficient of friction and minimal heat distortion for high-speed machining of nonferrous materials.

The GX24-WDN10 inserts feature chipbreaker geometry, laser-marked ISO and ANSI corner-radius designation, and widths ranging from 0.078" to 0.118" (2 to 8 mm).
