Achieve higher penetration rates than standard twist drills for light duty machines.

Wohlhaupter India will also feature the new 4TEX drill, ideal for making shallow 2xD, 3xD, and 4xD holes in the 12-47 mm (.472" - 1.850") range. Industries working with a variety of materials - especially aerospace, heavy equipment, automotive, and energy industry applications - will benefit from the excellent chip formation provided by this drill's unique geometries. It is also an excellent choice for making interrupted cuts or drilling on angled surfaces. The new design even enables certain operations to be performed without initial milling of the surface.

The 4TEX drill's single effective cutting edge provides higher penetration rates than standard twist drills for light duty machines. In this design, the center coolant outlet was eliminated to increase the drill's core strength, resulting in improved hole size and straightness. Instead, dual twisted coolant outlets were added to improve hole straightness and penetration rates by enhancing coolant flow and generating superior chip evacuation.

Insert geometries for standard ISO material categories improve hole quality and penetration rate, while eliminating issues from chips wrapping the tool.

4TEX inserts are 4-sided, lowering customers' cost-per-hole. The distinctive insert shape improves surface finish, hole diameter, and hole straightness by providing a superior balanced cut compared to ISO inserts. The drills are stocked in both imperial and metric shanks with standard fractional diameters, as well as every ½ mm diameter up to 26mm and every 1mm up to 47mm assuring fast delivery.
