Cutting fluid: tips to save your taps
We all know it, dealing with a broken tap can be a pain.
Although there are several ways to deal with this it, drilling out a broken tap out is generally time-consuming, challenging and requires a lot of extra work.
How to prevent this from happening? Two magic words: CUTTING FLUID.
Cutting fluid is a (cutting tool) life saver in operations like tapping, reaming and drilling.
Drilling in particular calls for lubrication at the drill’s tip and flushing to eject chips from the hole. Without fluids, chips can bind in the hole, and average roughness of the machined surface can be twice as high as what is possible with a wet operation. Lubricating the point of contact between the drill’s margin and the hole’s wall can also reduce the torque required from the machine.
Although some alloys, like aluminum, are typically more forgiving due to the relatively low cutting temperature, it is generally better to use cutting fluid in any occasion.
What type of cutting fluid?
There’s definitely a great variety of lubricants out there that can be used. Some of them are more suitable for soft alloys, while some others are designed to perform on harder materials, like Titanium or Inconel.
Here are some of the best options available in the market and the material they are most suitable for.
The classic. Probably one of the most used cutting fluids in the trade. Although the regular version is expected to work well on any type of material, we recommend using the Tap Magic Aluminum on aluminum parts to avoid stains.
Another pretty solid cutting fluid, and it’s been around since the 1800s. Works just as well as a lot of other fancier and more expensive fluids in the market.
Not exactly the cutting fluid that any machinist would imagine, but it’s cheap, and can be used in multiple occasions. Rub some of it on your tap and be sure that it won’t break.
