What is a Spiral Point Tap?
A spiral point tap is the right tool for making a through-hole that goes all the way through a piece of metal. It has a cutting tip with a special angle that pushes the metal chips forward and drops them safely out of the hole at the bottom. The waste is pushed forward instead of being moved, so the core of this tool is made of thicker, stronger steel. This heavy-duty design lets you run your CNC machines at much faster speeds if your plant makes a lot of flat metal flanges, brackets, or structural plates. You can cut clean, perfect internal threads without ever having to stop an automatic production line to clear a clogged tool because you can shoot the debris out of the way right away.
The Hidden Cost of Cheap Spiral Point Taps
For a through-hole to thread, the metal chips need to be pushed out the bottom. The cutting tip on a cheap spiral point tap won’t be able to move the waste forward if it isn’t ground well. The metal chips get stuck in the hole and do not fall out. Instead, they jam against the tool. Your automated CNC spindle keeps going very fast, so this quick friction will either tear up the internal threads you just cut or break the tap completely. You suddenly have a broken piece of work or a broken tool stuck in your part, which means you have to stop the machine and lose hours of work time.
When factories try to save money by buying cheap tools, they end up losing money on scrapped parts and assembly lines that have to be stopped. Hanöki makes heavy-duty spiral point taps that are designed to be used safely with high-speed CNC tapping. We make sure that our cutting points are very precisely ground so that they push every chip forward and out of the way. When you buy straight from our factory, you get strong, reliable tools that keep your production going without stopping to protect your valuable workpieces.

Speeds Up Your CNC Cycle Times
When you’re making open-ended through holes, you don’t want chips that get stuck in the wheel to slow it down. With spiral point taps, the metal waste is pushed forward and out of the cutting zone completely. Because the tool’s flutes never get clogged with dirt or dust, you can run your automatic equipment at much higher speeds and finish big orders a lot faster.
Provides Maximum Tool Rigidity
To hold chips, standard tapping tools have deep holes, which weaken the steel over time. Spiral point taps have a much thicker core because they only use their angled front tips to push waste forward. Because the structure is stronger, you can use a lot of cutting force without worrying that the tool will bend or break in the middle of the cycle.
Keeps Through Holes Completely Clear
During drilling, if metal waste stays inside the part, it can mess up the whole process. With spiral point taps, the sharp metal chips are thrown ahead of the cut. The chips just fall out of the bottom opening when you make a through-hole. You never have to worry about metal that is too close together getting stuck in your CNC machines.
Eliminates Slow Pecking Cycles
When using regular cutting tools, your workers often have to turn the CNC machine around more than once to break up chips. With spiral point taps, the waste is always pushed out ahead of the teeth, so you can thread the whole depth in one smooth motion. You get extra time back with every hole you drill.
Prevents Scratches on Fresh Threads
Chips that get stuck in the tool holes damage the finish when they rub against the walls of the newly cut metal. Spiral point taps keep the cutting area clean by pushing all the metal scrap forward and away. You get internal threads that are smooth, very accurate, and will easily pass your strict quality gauge tests.
Forces Coolant Right Where You Need It
The worst thing for your cutting tools is extreme heat. Spiral point taps leave a place behind the tool that is free of chips because they push the chips down and out of the way. The high-pressure cutting fluid in your machine can easily flood into the hole and wash away the heat right away. This will keep your teeth sharp for many more runs.

Spiral Point Taps Application Areas
When you manufacture large steel flanges for oil pipelines or high-pressure water systems, you must thread dozens of open-ended holes to bolt the pipe connections together. You run spiral point taps because they shoot the metal chips straight down and out the other side. This keeps the tool flutes completely empty, allowing your CNC to run at top speed and produce secure clamping points for the heavy pipes.
To build massive excavators or heavy lifting cranes, your factory relies on bolting thick steel plates together. These open structural holes require extremely strong threads. Because spiral point taps feature a thicker, reinforced solid core, you can aggressively power them through these tough steel plates without breaking the tool. They push the heavy chips forward, giving you perfectly threaded through holes for your heavy-duty assembly bolts.
If your facility produces industrial cooling towers or large heat exchangers, you must drill and thread hundreds of holes through flat metal tube sheets. You rely on spiral point taps to blast the metal waste through the bottom of every single open hole. This forward chip ejection means you never have to stop your automated machines to clear jammed debris, drastically cutting down your mass-production time.
When you build heavy farming equipment like harvesters or industrial plows, you constantly work with tough iron brackets that need open-ended mounting holes. Spiral point taps easily drive the stringy metal waste ahead of the cut and drop it safely onto the shop floor. This clean, continuous cutting action ensures your structural bolts will fit smoothly without binding, keeping your heavy assembly lines moving fast.
A spiral point tap is used to make through holes (holes that go all the way through the metal) with internal threads. Its unique angled tip carefully moves metal chips forward and out the bottom.
It’s called a “gun tap” by machine operators because the metal chips are “shot” ahead of the cutting action. This keeps the tool flutes clear of any waste.
In a closed blind hole, you should never use a spiral point tap. It moves trash forward, so the chips will quickly pack against the solid bottom and break your tool.
The flutes (grooves) don’t need to be deeply cut because this tool moves waste forward instead of lifting it up. This makes the solid steel body much thicker and stronger, so it can handle more CNC torque.
Because the front of the spiral point tap is at a certain angle, the cutting force is directed to neatly cut the metal and push the chips down, so they don’t wrap around the tool.
For through holes, you use a spiral point tap because it moves chips forward. For blind holes, a spiral point tap is used because its twisted lines move chips up and out.
For through holes, you should always use a spiral point tap if you have an AI CNC. A normal straight flute tap only holds chips in its holes, which means it breaks and gets clogged up quickly.
Of course, but only for machine work. Hand taps are used for turning things by hand. A spiral point tap is designed to work with the constant, high-speed power of an automated CNC machine.
A roll form tap can shape metal without chipping it, but it needs holes of a certain size and metals that aren’t too hard. You need a spiral point tap if you need to cut the material instead of shaping it.
Yes. A spiral point tap has less friction because the angular tip moves the chips out of the way more easily. Your expensive CNC spindle needs to put out a lot less torque to do this.
To work with aluminium, you need a spiral point tap with highly polished flutes that is not coated (bright finish). Aluminium is soft and sticky. This keeps the aluminium from joining to your cutting edges when it’s cold.
Yes. You need to use a spiral point tap made of strong HSS-E (cobalt steel) with a fancy finish. The tough, stringy stainless chips will be pushed away from the heat zone by this tool.
In most cases, no. When cut, cast iron turns into a rough dust. For cast iron powder, a straight point tap works better because there are no stringy chips to push forward.
Most tools will burn up when you try to thread hardened steel metals. To do this, you need a very rigid CNC setting and a spiral point tap made from solid carbide or powder metal.
Yes. A spiral point tap works great for plastic through holes because it quickly shoots the plastic waste out the bottom, stopping it from melting from friction heat inside the hole.
It is possible to run a spiral point tap much faster than a spiral point tap because the core is so strong. Always set your exact RPM based on how hard the metal part is.
Yes. The tool moves chips forward, but you need to flood the hole with coolant to get rid of all the falling debris and keep the cutting teeth smooth.
Your CNC feed rate needs to be just right for the tool. To find this, multiply the exact RPM of your spindle by the exact thread size of your spiral point tap.
A rigid tap is always the safest way to do something. When the feed and rotation of the machine are properly timed, the spiral point tap can cut clean threads without ripping the metal as it comes out.
Use a high-precision collet chuck if your machine can do stiff tapping. The spiral point tap must be held in place with a tension-compression (floating) holder if you used older tools.
Most spiral point taps break because the person using them makes a mistake. They either run the tap into a blind hole with chips packed on the bottom, or they make the starting hole too small for the tap size.
Too big of threads happen when the tool goes into the hole at an angle, when the cutting teeth get dull, or when the feed rate on your CNC machine is not in sync with the spindle speed.
When the torque on the CNC spindle goes up, the tap starts to make a loud squealing sound, or finished parts fail thread gauge checks, it’s time to change the tool.
The tap is made of hardened steel, so you can’t drill a hole in it. To burn out the tool, you need to either use a special tap extractor or take the part to an EDM station.
Of course. Premium coatings, such as TiN, TiCN, or TiAlN, keep heat out. They keep the cutting teeth from getting soft in very hot places, so your spiral point tap can go through thousands more holes.
How to Choose the Right Spiral Point Tap for Your CNC
The fastest way to break a tool and ruin an expensive piece of work is to use the wrong tap on your CNC machine. If you use a simple straight-flute tap to trap metal chips in a hole, the heavy torque from your spindle will break the steel right away. The cutting tool must be exactly the right size for the hole in order to protect the parts. Always use a spiral point tap to safely shoot metal waste down and out of open through holes. Only use a spiral flute tap to pull waste out of closed blind holes. As long as you use the right high-pressure coolant and flute geometry, you can avoid tool jams and keep your business from having to pay for expensive machine downtime.
