Prototyp Prototex Tap

Walter USA LLC has unveiled its new Prototex HP-P, a high-performance tap that can handle the demands of large batch sizes and mass production. Targeted at steel applications from 600-1250 N/mm2 (175-300 HB), the three versions of Prototex HP-P feature HSS-E or HSS-E-PM substrates, TiCN or TiCNX coatings for heightened wear resistance, an optimized spiral point, and a through coolant design. Thanks to features like these the Prototex HP-P is able to deliver high tool life for a tap in steel (175-370 HB). This in turn results in reduced tool costs and, because of fewer tool changes, it also results in less machine downtime.

Walter supplies three different versions of the Prototex HP-P, each optimized for a particular set of applications. The Prototex HP-P (1) has a substrate of HSS-E-PM and a TiCN coating and is particularly effective in unstable conditions. HP-P (2) has an HSS-E substrate with a TiCNX coating and delivers high tool life under normal conditions. The HP-P (3) features an HSS-E-PM substrate and TiCNX coating and can deliver exceptional tool life under good conditions, according to the company. The Prototex HP-P is available via quotation through Walter's Specials Department.

Related Glossary Terms

  • coolant


    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.

  • tap


    Cylindrical tool that cuts internal threads and has flutes to remove chips and carry tapping fluid to the point of cut. Normally used on a drill press or tapping machine but also may be operated manually. See tapping.

  • titanium carbonitride ( TiCN)

    titanium carbonitride ( TiCN)

    Often used as a tool coating. See coated tools.

  • wear resistance

    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.
