Taps are one of the most commonly used cutting tools for machining internal threads in manufacturing, widely used in thread cutting on equipment such as ordinary lathes, drilling machines, and tapping machines. YAMAWA, a tap brand originating from Japan, has been focusing on the research and development and manufacturing of high-precision thread cutting tools since its establishment in 1923, enjoying a high reputation in many industries including automotive, aerospace, machinery manufacturing, home appliances, and IT. Its products are characterized by their complete range, stable quality, good wear resistance, and long service life. Known for its precision, YAMAWA's diverse product line presents a significant challenge. However, for many technicians, choosing the right tap based on specific machining needs and identifying the optimal application time is a core concern.
II. Main Types and Characteristics of YAMAWA Taps
YAMAWA boasts a comprehensive tap product system, which can be broadly categorized into the following types based on structural form, machining principle, and application scenario:
(I) Spiral Taps
Spiral taps, also known as spiral flute taps, have spiral grooves, a significant difference from the straight flute structure of ordinary hand taps. During tapping, the upward rotation of the spiral grooves... Used to smoothly discharge chips out of the hole, preventing chip residue or blockage in the groove, thus effectively preventing tap breakage and cutting edge chipping. YAMAWA series spiral taps are available in blind hole and through hole types, generally made of HSS high-speed tool steel, capable of quickly and smoothly cutting high-precision threads. Spiral flute taps are widely used in blind hole machining on CNC machining centers, offering advantages such as high machining speed, high precision, good chip removal, and excellent centering. Standard models include N-SP, HC-SP, OS-N-SP general-purpose types, and increased precision types.
(II) Tip Taps
Tipping taps are mainly... For through-hole machining, the chip removal direction should be forward to keep the groove clean, reduce cutting resistance, and prevent tap damage due to chip blockage. The tip tap has a larger core size and better strength, capable of withstanding greater cutting forces, thus allowing for higher speeds for high-precision thread machining than standard hand taps. It is ideal for machining non-ferrous metals, ferrous metals, and stainless steel; tip taps should be the preferred choice for through-hole threads. Main models include general-purpose types such as N-PO, HC-PO, and OS-N-PO, as well as higher precision types.
(III) Straight Fluff Taps
Straight fluff taps are divided into... There are two types: machine-grade and hand-grade. Machine-grade taps are typically made of high-speed tool steel with ground threads and are suitable for machine tool tapping; hand-grade taps are mostly made of carbon tool steel or alloy tool steel with rolled (or cut) threads and are suitable for manual operation. Straight flute taps are the most versatile, capable of machining both through holes and blind holes, non-ferrous and ferrous metals, and are the most economical. Representative models are the HT and HT-1 general-purpose high-speed steel straight flute taps.
(IV) Forming Taps
Forming taps, also known as chipless taps, utilize the principle of metal plastic deformation for machining, producing no chips, and belong to the chipless forming thread machining process. Without a chip flute, forming taps have a larger core, resulting in higher strength and less breakage. Forming taps are best suited for machining materials with good plasticity, such as aluminum, copper, zinc, brass, and low-carbon steel. The resulting thread has a continuous metal fiber structure, forming a chilled hardening layer on the surface, significantly improving thread strength and wear resistance-compared to cutting threads, forming threads can have approximately 30% higher strength and 40% to 50% higher surface hardness than the core. Furthermore, forming taps typically have a service life 3 to 20 times longer than cutting taps, resulting in higher production efficiency.
(V) Superhard Taps
Selection of Superhard Taps Made from ultra-fine particle ultra-hard tungsten steel, with a specially treated cutting edge clearance angle, and can be titanium plated, it is suitable for machining difficult-to-machine materials such as tool steel, die steel, and special steel with a hardness of HRC50 to 63 after heat treatment. Its lifespan is dozens of times longer than ordinary cutting tools, and it can repair worn cutting edges with a grinding depth of only 0.03mm and center runout controlled within 0.02mm. The product range covers various tooth profile standards including PT, NPT, NPS, PS, and PF, and includes metric, imperial, US, and tubular threads.
