Baban Countersink Drill Bit Set - Perfect for Creating Smooth and Precise Holes in Wood and Other Materials.

Santos Eduardo Murillo: I made the mistake to use em in metal it worked but there's no sharp now in one of em

Brian LaRochelle: These worked OK on soft and medium hard wood, but struggled to cut into low-grade stainless steel. I would recommend a better known brand with good reviews on metal, if that's how you are intending to use them.

Marcos Alfonso Lopez Padilla: Lo bueno:
la variedad de tamaños aunque realmente solo utilizas 1 o 2 de los avellanadores
Los materiales se sienten de calidad
La posibilidad de usarlos con herramientas o accesorios con cambio rapido de punta
Lo malo:
Lo que me decepcionó ea que el filo es mínimo y en madera blanda si no tienes cuidado tiende a desgarrar la pieza.
Como en algunos otras recomendaciones creo que es mejor elegir una opción de mayor costo que posean y mantengan el filo.

Will-Review4uWill-Review4u: I have been looking for a new countersink set of bolts for quite some time and only found the ones with two or three cutting edges. I was surprised to find this set with not only five cutting edges or flute per bit, but also with six differently sized countersinks. The value of having different sizes is that they can be matched more readily to the size of screw head. I've used two of them and found that they are quite sharp and cut very aggressively. I would suggest that buyers be sure to run a couple of test cuts before using them on a piece of work. I wanted the quick change out notch that allows me to snap in and out of my impact driver or quick change chuck on my drill press.

Roddyvr: The bits are useful sizes but I have found that they lost their sharp edges after minimal use. More expensive options might be more cost effective in the long run.

Matthew: Please read the update below.

The original review: This is a set of six countersinks, starting at 6mm (~1/4") and going up from there. My set was $8, which is really inexpensive. REALLY, really inexpensive. ONE countersink is $8 at most hardware stores where I live.

I am not a machinist, nor an expert on machining. I work with mostly wood, some aluminum, and some softer steels. So I cannot attest for how they would handle tough materials. For what I do, they are fine -- no problems yet. They have 5 cutting edges -- a lot of c-sinks have six, but this does not matter to me. They are mounted on quick change 1/4" hex shanks, which is handy.

Keep drill speeds down, use cutting oil or other lube on metals, and I think they will serve you well. Thanks for reading.

Updated Jan 2023: Having used the countersinks in my shop, I found that they are just TOO SOFT for use on steel or cast iron. Wood, brass, aluminum -- these are OK. Harder materials will damage the countersinks quickly. So (as usual) you get what you pay for. I will use them on softer materials, but will keep higher quality parts around for more demanding materials.

Red Lightning: At the price you pay these are good general purpose counter sinks. Since they have hex shanks you can use them in hex shank holders to countersink some materials by hand such as aluminum, plastics and wood.

You might see some comments about chattering. Chattering is often caused by using higher or slower speeds than necessary or failing to properly align the bit properly. Many drill presses don't have speeds slow enough to use counter sinks properly and you should experiment on practice materials before trying it on a finished piece. Trying to use one speed on all materials is almost sure to cause problems.

Also, don't forget to apply lube before countersinking. You don't need anything special, even WD40 will work, just practice a little and you find the best sized countersinks and the best speeds for the diameter of the hole.

One other cause of chattering is too light a pressure on the bit and trying to start the countersink slowly. Even with a slightly warped countersink, if you apply a bit more pressure and don't feather in the bit the result will be a smooth and chatter free result.

Don't forget, this is a basic countersink bit set and apply your...
