The new 4TEX drill from Allied Machine & Engineering is engineered to deliver optimal chip formation and evacuation and provide higher penetration rates than standard twist drills for light-duty machines. This indexable insert drill excels in applications with interrupted cuts or when drilling on angled surfaces. 4TEX is also ideal for making shallow 2xD, 3xD, and 4xD holes in the 12 - 47 mm (.472” – 1.850”) range.
The design increases core strength, improving hole size and straightness. Dual twisted coolant outlets improve penetration rates by enhancing coolant flow and generating superior chip formation and evacuation. 4TEX inserts are four-sided to maximize the tool life of each insert.
Available geometries have been developed for steel, stainless steel, high temperature alloys, nonferrous and iron, which are optimized for excellent chip formation and wear resistance in difficult applications.
Related Glossary Terms
Substances having metallic properties and being composed of two or more chemical elements of which at least one is a metal.
Fluid that reduces temperature buildup at the tool/workpiece interface during machining. Normally takes the form of a liquid such as soluble or chemical mixtures (semisynthetic, synthetic) but can be pressurized air or other gas. Because of water’s ability to absorb great quantities of heat, it is widely used as a coolant and vehicle for various cutting compounds, with the water-to-compound ratio varying with the machining task. See cutting fluid; semisynthetic cutting fluid; soluble-oil cutting fluid; synthetic cutting fluid.
- indexable insert
Replaceable tool that clamps into a tool body, drill, mill or other cutter body designed to accommodate inserts. Most inserts are made of cemented carbide. Often they are coated with a hard material. Other insert materials are ceramic, cermet, polycrystalline cubic boron nitride and polycrystalline diamond. The insert is used until dull, then indexed, or turned, to expose a fresh cutting edge. When the entire insert is dull, it is usually discarded. Some inserts can be resharpened.
- wear resistance
Ability of the tool to withstand stresses that cause it to wear during cutting; an attribute linked to alloy composition, base material, thermal conditions, type of tooling and operation and other variables.
