Drill Router Bits


Choose the milling cutter that best suits your needs in our catalogue. Drills for drills are called this because they are often used "manually" and inserted in our drill, which can be manual or columnally as the category says.

I have written "often" because sometimes we can find them also in the CNC automatic machining centres, those large machines with pre-loaded tool holders for milling, sizing, drilling and those who have more than one machine put it all together (in a machining cycle that programs the technician specialized in PC).


What is meant when it comes to carbide drill saws (HM) or steel (SP)?

Yes, you have read well.... they can also be called SEGHE for column drill, as PUNTS for column drill, but a school of thought "ancient" states that they are without a shadow of a doubt cutters..... Who are we to contradict each other? Some traditions must be respected even if we are in the "Fraiser generation".

All carbide cutters, called WIDIA and signed with HM/HW, are all those cutters that carry the welded "workpiece" in this category.

Welding takes place through an advanced process called "by induction" and, combining 3 SPECIAL chemical layers, this maximum robustness is achieved

On the other hand, there are different those in SP steel (which stands for alloy) that are "All of a piece", so you will not see any welds and various coatings.

You can easily distinguish also from the weight of the milling cutter itself, that in HW is heavier than that in HS (I know, another strange acronym... quiet, it is only the symbol of Steel J, then all the numbers that you could find in front are the myriads of molecular variations of addition of material for who knows how much complicate life to people... luckily we are there that we indicate the most correct one)

How are they used?

All the cutters, as the category is named, are designed and ideal to be inserted on a drill (better column drill, which perfectly follows the machining without even having margins of risk, using the protections, I recommend!)

The FR. 501 - 502 - 502 - 503 - 504 - 505 - 506 series are all suitable and designed to make zipper seats (obviously you can drill holes or milled for any use, but the standard name is the name you need to give, start J)

The only difference between these is the material, which we have learned to recognize first, and the cutting type, which we will go into later.

But the FR. 502 cutter FR. 502 in Stainless Steel SP or the Forstner FR cutter. 505-506, are they not equal?

It may sound like this but if you're a discreet observer you might already have noticed it, the 502 series has 2 lateral engravers like cousins in Carbide, while the Forstner series have circular engravers, all around the center of the cutting edge.

Difference? Those with two engravers are (just) more precise and allow for a (poor) longer life.

What to choose? Between the two costs less than the Forstner, and the reason you have just read it, so my advice is always to evaluate the processing well and then choose according to various factors (check the post that I did in the blog entitled "How to choose a cutter for wood", you find them all you need to not make mistakes so don't throw time and money).

Sometimes the Forstner are sometimes divided into two sharp edges;

Standard cutting edge: Provides better guidance, but has a tendency to overheat too much, so overcome the problem the larger diameters are designed with toothed cutting edge (FR. 506).

Toothed cutting edge: Designed not to overheat too much, for larger diameters

The FR. 507 rose cutter is suitable for working in wood.


you want to find these rose windows in a table leg, in the downhill bed in the mountain hut or in the most unthinkable places... with our series you can make the most of your imagination, the sturdy cutting edge in HW will never leave you alone

Very recommended or almost mandatory column drill for this milled material

Finally, but not by order of importance, the FR. 508 called Drill Cup (or saw, for the same thought that we wrote above)

Needless to say, we all know that it is a server for making clean and symmetrical circular cuts (holes) on wood, even of large diameter. (it's a joke, I swear that in order to find this beautiful definition I had to ask the old man for help, and for those who read the book "The Fraiser Theory" he knows what it means to me.


These cutters are very versatile and we can find them both from the fitter who comes home to put your shelf on, and from the big furniture maker who makes furniture for that famous yellow-blue chain (not if Ikea can say, I'm afraid of some complaints, hopefully not).

Our range also allows you to have a milling cutter 3 times more resistant to economic alternatives thanks to our technological treatments based on a SPECIAL and SECRET combination of temperature parameters - duration (for hardening) and heat - pressure (for sintering).

Of course, all this is nullified if you are not in good condition (and it's not your fault, trust, around is full of people who look only at the turnover, neglecting the customer and his need) to choose the type of cutting edge and the type of cutter that is right for you.

Getting to know, studying and specialists is only the first step towards success. If you're new to the world, if you need some review or just want to measure yourself (and maybe help us to improve) with professionals, I recommend you make a leap in our blog (you can find it at the top of the menu -> Fraiser -> Blog) where we have been naked for you, we try to tell and explain in the easiest way this wonderful world of milling, giving something even once in a while.


Good milled (with the drill column) to everyone
