What Are the Advantages of Spiral Point Taps in Tapping Automotive Engine and Transmission Parts?
2025-06-16
In automotive component manufacturing, engine and transmission parts are often made of stainless steel, alloy steels, and other high-strength materials that are difficult to machine. Spiral point taps stand out as the preferred tool for tapping such components due to their design and material benefits.
Firstly, efficient chip evacuation. Spiral point taps push chips forward out of the hole, preventing clogging and reducing the risk of tap breakage. This is particularly useful for through-hole applications in engine blocks and gearbox housings, significantly improving tapping efficiency.
Secondly, higher thread accuracy and consistency. With sharp cutting edges, spiral point taps minimize burrs and deviations during tapping. This ensures stronger and more reliable thread engagement for bolts in engine and transmission parts, enhancing sealing and durability.
In addition, excellent wear and heat resistance. Taps made from cobalt-containing HSS, such as HSS-M35, maintain sharp cutting edges under high temperature and high-stress conditions. This makes them ideal for difficult materials like stainless steel gears or engine housings, lowering the risk of tool breakage and extending tool life.
Finally, suitability for mass production. The automotive industry requires high-volume and high-efficiency production. Spiral point taps reduce tool change frequency and ensure consistent thread quality across batches, minimizing scrap rates and improving productivity.
