                  Carbide Hardmetal Taps

                  Carbide hardmetal taps "Tap evolution inevitably must develop in carbide as all cutting tools have... Introducing the most comprehensive and specific range"

                  A carbide hardmetal tap produces the same thread as in HSS, however, its function is different.

                  Carbide hardmetal taps The structure is very stable, consisting of sub-micro grain particles being consistent and hard in nature. It has a character which is more resistant to abrasion, pressure, heat, and material adhesion. T-TECH taps further enhance this benefit being through coolant. In essence it offers a longer or faster and more consistent performance in applications of attrition.

                  carbide hardmetal taps

                  Selection is appropriate in three main areas...

                  • High volume production in materials with abrasive qualities. An obvious example is tapping automotive components in aluminium and iron. Fluteless cold forming taps are ideal for these type of applications, tapping faster without any resulting swarf
                  • Materials which exhibit high wear characteristics or a "closing" nature. Composites - pure alloys such as tungsten, copper, etc - "exotics" - iron - alum alloys.
                  • Materials hardened above Rc40. Steels and "exotic" alloys.

                  Once the correct selection has been made, a carbide tap will consistently demonstrate longer life. This benefit results from its characteristics previously described. There is particular benefit in speed and life when fluteless cold forming taps are selected. Consideration must be given to the entirety of the application. Carbide is more brittle, therefore contributory factors to success or failure may comprise of the following: rigid work piece - rigid tapping avoiding shock or undesirable "float" - vibration.

                  The variety of applications and resulting geometry applied to HSS, is reproduced in carbide. The styles described below are comprehensive in creating a standard range. The Tool Selector guides you through the complexity of styles, or simply contact us to make the right choice.
