In machining, taps are used for internal threading of detachable and re-fittable fastening elements. Choosing the right tap type for the material and manufacturing method extends tool life and improves thread quality.<\/p>\n

In this article, guided by Temak Teknik<\/strong>, we examine the types of taps, their applications, tap substrate materials and coating properties.<\/p>\n

1. Types of Taps by Working Principle<\/h2>\n

Hand Taps (Set of 3)<\/h2>\n

Tools made from HSS, generally used in manual applications:<\/p>\n

    \n
  • No. 1 Tap (Single Ring) – Taper:<\/strong> Has a long chamfer and taper and is used to start the thread.<\/li>\n
  • No. 2 Tap (Double Ring) – Intermediate:<\/strong> The intermediate tap that deepens the thread profile.<\/li>\n
  • No. 3 Tap (No Ring) – Bottoming:<\/strong> The finishing tap that sizes the thread and completes the tapping operation.<\/li>\n<\/ul>\n

    Machine Taps<\/h2>\n
      \n
    • Straight Flute Taps:<\/strong> Preferred for through holes (open-ended holes).\n
        \n
      • Straight Flute Type:<\/em> Collects the chips in the centre of the flutes.<\/li>\n
      • Spiral Point (Gun Nose) Type:<\/em> Pushes the chips straight ahead and down.<\/li>\n<\/ul>\n<\/li>\n
      • Spiral Flute Taps:<\/strong> Because they evacuate chips upwards instead of pushing them down, they can be used reliably in blind holes<\/strong> (closed holes) as well as through holes.<\/li>\n
      • Forming (Roll) Taps:<\/strong> Produce the thread form by displacing the material without removing chips. Preferred in the series production of soft materials such as copper, aluminium and brass.<\/li>\n
      • Interrupted Thread Taps:<\/strong> Feature alternate teeth removed from the thread. Used in soft materials such as polyamide or aluminium and for fine threads to increase strength.<\/li>\n<\/ul>\n

        2. Tap Substrate Materials<\/h2>\n

        Taps have different substrate compositions depending on the hardness of the workpiece and the operating conditions:<\/p>\n

          \n
        • HSS (High-Speed Steel):<\/strong> Commonly preferred, generally for hand taps.<\/li>\n
        • HSS-E (5% Cobalt):<\/strong> The most common type for machine taps. Its cobalt content provides wear resistance and high heat resistance.<\/li>\n
        • HSS-M (PM \/ Powder Metallurgy):<\/strong> Provides long tool life in difficult materials such as nickel alloys, stainless steel and titanium.<\/li>\n
        • HSS-E V3:<\/strong> Delivers outstanding performance when tapping high-hardness materials.<\/li>\n<\/ul>\n

          3. Coatings and Colour Codes<\/h2>\n
            \n
          • Coated Taps:<\/strong> Although the initial purchase cost may seem high, the lubricity, high wear resistance and long tool life they provide significantly reduce the total manufacturing cost.<\/li>\n
          • Colour Codes:<\/strong> Manufacturers add colour codes such as blue, red, black or yellow to tap shanks to indicate the material group the tap is suited to, its coating type and its application.<\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"
