<p>The need to resist a large amount of torque while bearing a large amount of weight led to the replacement of wooden bolts, nuts and plugs with metal ones. With metal-working becoming a part of large-scale industrial factories and manufacturing units, there was a constant need for creating newer fastening devices or replacing the older metal fasteners. The evolution of machining industry sub-planted most in-house works and milling practices using hand files became a thing of the past. The standardization of threads in the 20th Century led to a standardization in thread grinding practices and use.</p><p>Let us assume that a bakery equipment factory worker based in Chennai, needs to create a hole to use a M3x50 Allen Head socket Screw to fasten two metal objects. He reaches out to the nearest hardware store and enquires for the appropriate tool. HSS Hand tap is what the shop-keeper will advice the worker to use. A HSS Hand Tap in Chennai store will be used to create new threads or repair existing threads. Physically, a Hand Tap is a screw like tool with longitudinal grooves used for cutting the screw threads.</p><p>The Taps, just like any tool or industrial equipment can be classified based on its quality. You need to have the right tool for the right job.&nbsp;&nbsp;</p><p>Machine grade are the most accurate and sharpest and is the first choice for any repair that needs precision, quality, and productivity.&nbsp;The Machine grade taps are priced at the higher end as they are cut and machined to precision tolerances that allow the tap to cut to a predetermined depth of thread. Loose fasteners will lose their holding strength, but a fastener that fit too tightly will fail to engage properly.&nbsp;Machine grade taps are also capable of high machine speeds in CNC lathes and milling machines cutting many holes consecutively and at higher feed rates.&nbsp;&nbsp;</p><p>Medium grade taps are often found in jobber warehouse-type stores and are of generally a good quality multi-purpose use.&nbsp;Best used in hand applications and where tap life and precision are not as important as availability and cost.</p><p>Quality entry-level grade taps are usually found in hardware stores and are best used for hand applications. However, they have a limited life and are less tolerant for the misalignment of the tap with the bore.&nbsp;&nbsp;</p><h2>TYPES OF HAND TAPS</h2><p>The HSS Hand Tap is a set of three pieces: Taper, Second, and Bottom tap.</p><p>The HSS Hand Taper Tap has a visible and pronounced tapering of the cutting edges. This provides a gradual and less aggressive cutting action. The distinct feature is the 8 to 10 threads that taper from the tip to the full cutting force diameter. A HSS Hand Taper Tap is normally used as the first tap for difficult blind holes. The gentle taper of the cutting edge allows the cutting of a straight hole in especially hard materials. The HSS Hand Taper leaves incomplete threads cut at the bottom of a blind hole and so is never used as the final tap.&nbsp;</p><p>A Plug tap or the HSS Hand Second Tap has a less pronounced taper to the cutting edges giving it a gradual cutting action that is less aggressive than that of the HSS Hand Bottom Tap but more aggressive than a HSS Hand Taper Tap. The plug tap will have 3 to 5 tapered threads before the full cutting diameter is engaged. The HSS Hand Second Tap is great when used with through-holes, as are as easy as the Taper Tap to start with, but also offer a more complete set of threads.&nbsp;</p><p>The HSS Hand Bottom Tap among the set of HSS Hand Tap in Chennai markets is the third type. Hand Bottom Tap have 1 to 2 tapered cutting edges before the full cutting force is engaged. This tap is extremely hard to start threads with, but is capable of cutting threads all of the way to the bottom of a blind hole. HSS hand Bottom Tap are best used after a taper or plug tap has been used to cut the initial thread.</p><h3>SPIRAL VS STRAIGHT FLUTE TAPS</h3><p>Spiral flute taps can be a great tool for cutting through softer metals and metals that do not chip (such as cast iron). The spiral flutes work just like that of a traditional drill bit, promoting the evacuation of cut material from the hole. The downside of spiral flute taps is their strength. Being that deep flutes are cut into the tap; the cross-section of the cutting web is not as thick as that of a straight flute tap.</p><p>Straight flute taps are a robust cutting tool with flutes that run straight down the shaft of the tap. The larger cross-section of the cutting edge makes the straight flute tap a great solution for cutting threads into hardened metals. When cutting or cleaning threads in a blind hole, the technician needs to be patient while using this tool, let the cutting edge do the work and continually back the tap out and blow air into the hole to evacuate the removed material. A build-up of chips below the straight flute tap will lead to breakage and less clean-cut threads.&nbsp;</p><p>Choosing the right tap always depends on the type of hole you are trying to cut or clean, as well as the type of material you are tapping.
