JIS Extended Spiral Point Taps

Wilson's classy JIS Extended Spiral Point Taps are a special type of spiral point tap, whose "elongated" design refers to the total length of the tap being longer than the standard length, allowing it to penetrate deeper into the hole for processing. It is both sturdy and durable, and the price is reasonable. It is particularly suitable for thread processing jobs with high requirements.

Product features

1.Design of "Deep Breakthrough" in Deep Hole Machining

The handle adopts an elongated optimized structure, specifically designed for thread cutting needs in deep hole scenarios. For example, in the machining of through holes in the cylinder body of automotive parts, this design can easily reach depths that ordinary taps cannot reach (with a length to diameter ratio of over 3.5 times), just like installing an "extension arm" on the tool, allowing deep hole threading to no longer be limited by hole depth, especially suitable for deep hole component machining in the aerospace field.

2.The 'cleaner' function of the spiral chip conveyor

The spiral chip guide groove at the front end of the tap is like an "automatic chip discharger", which pushes debris out of the hole along the groove during cutting. Imagine that when processing aluminum alloy parts, this design can prevent chips from accumulating in the cutting area and keep the cutting head clean, just like a vacuum cleaner cleaning up garbage while working. It not only reduces cutting resistance but also avoids tool jamming caused by chip blockage. In deep hole machining such as high-speed rail axles, this chip removal efficiency can improve machining stability by more than 50%.

3.Precision carving ability in fine tooth processing

The dimensional stability during processing is comparable to precision measuring tools - the tooth profile is clear enough to rival gear molds, especially adept at "micro carving level" processing of fine threads. For example, in the micro screw hole processing of electronic devices, it can ensure that the size error of each thread does not exceed 0.02mm, just like using a carving knife to "draw threads" on the material. The finished product not only has high accuracy, but also the surface roughness can be controlled below Ra1.6. This characteristic makes it the preferred tool for processing medical device components.
