4TEX Indexable Carbide Drill Creates Optimal Chip Formation

According to Allied Machine & Engineering, the 4TEX indexable carbide drill is especially useful for drilling operations that include interrupted cuts, inclined work surfaces and angled breakouts, as well as high-temperature alloys and stainless steels. The drill is engineered to create optimal chip formation for efficient evacuation in holemaking processes, and it delivers higher penetration rates in light duty machines. The drill is ideal for applications that include shallow 2×D, 3×D, and 4×D holes in the 0.472” – 1.850” (12 mm to 47 mm) range.

The company has optimized 4TEX’s insert geometries for wear resistance and offers them in geometry/coating combinations for all ISO materials, including steel, stainless steel, high-temperature alloys, nonferrous and iron. Another benefit of its design is that the same insert can be used in either drill pocket, simplifying insert change out. The distinctive insert shape improves surface finish, hole quality and penetration rates, while eliminating issues from chips winding around the tool.

The drill’s design touts increased core strength, improving hole size and straightness. The flute space of the internal cutting edge side, where chips often cluster, is 1.6× larger than typical IC drills. Dual-twisted coolant outlets, coupled with the increased flute space, improve penetration rates by enhancing coolant flow and generating optimal chip extraction, the company says.
