Drills

Emuge Corp. announced it has expanded its EF-Series of high-penetration rate drills with a new line of submicrograin carbide coolant-fed microdrills. The EF high-performance microdrills range from 0.0295 in. (0.75 mm) up to 0.1181 in. (3.0 mm) in diameter, are all coolant through design, and are ideal for aerospace, medical and precision automotive applications designed for producing very small deep holes in steel, cast iron, stainless steels and nonferrous materials.

DrillMeister features simple and swift drill head indexing due to its self-clamping system. Tool replacement is easy: just replace the drill head. There is no need to remove the entire drill body from the toolholder and re-adjust the tool overhang, thus reducing a large amount of tool change time.

The RT 100 S drill from Guhring was especially developed for the complex machining of steel materials. It reportedly scores points thanks to high cutting values and consistently good hole quality. An especially stable and accurate cutting edge is produced thanks to the special micro-geometry.

Controx-Neuhauser introduces its Decoring Cut tool, which both drills through honeycomb composite panels and undercuts the skins (thus removing the cores) in a single labor-saving step. A sophisticated end tooth design enables Decoring Cut to cut through the top skin while maintaining tight tolerances with no delamination.

Tungaloy Corp. further expands its indexable-insert gundrill line, DeepTriDrill, with options down to a diameter range of 14-15.9 mm. Deep-hole drilling is a challenging operation and often creates a bottleneck in holemaking shops around the globe.

Small, deep and fast, these are the characteristics of the small drill CrazyDrill Cool SST-Inox. Due to internal coolant ducts, innovative geometry and innovative coating, the machining of stainless steels, nickel based super alloys and CrCo-alloys has become significantly simpler and process stable. This goes also for small diameters, as well as deep bores.

Walter has introduced two new products for the DC150 drill lineup: 3xD and12xD, both with coolant through the tool body. The DC150 is positioned in the Perform line—a tough, versatile and cost effective Walter Titex family of solid-carbide drills. The two, new length-to-diameter ratio drills join the 5xD and 8xD drills.
