Question:

My AKBU 35 PMQ suddenly won't start. What could be the reason?

Apart from the usual components in question, such as the motor and electronics, a sudden failure of the machine may be due to an incorrectly plugged connection cable. Please check the connection cable.

Question:

Are FEIN core drills “Made in Germany”?Are FEIN core drills “Made in Germany”?

The vertical range of manufacture in Germany is approx. 80%.
The majority of our core drilling machines therefore have the label “Made in Germany”.
Individual models are assembled at our site in India.

Are the cork profiles and the holder of the profile sanding set available separately?

Yes, the profiles and the holder of the profile sanding set are also available separately. You will find the corresponding order number in the attached image file.
You can obtain accessories from one of our specialist dealers in your area. You can find the address on our website under Dealer search.

Question:

Are there any other core drill holding systems?

Weldon 32, Weldon 1-1/4",

M18, Universal (WelNit, FullUniversal, One-Touch, Fusion II)

Can I resharpen / regrind my carbide or HSS core drills?

In principle, this is possible with carbide and HSS core drills.
However, a special grinding machine and the necessary rake and clearance angles are required.
There are special grinding companies that specialize in resharpening/regrinding.
As a rule, however, carbide and HSS core drills are not resharpened or reground. The costs for this are close to those of a new purchase.

Can I use Fein core drilling machines to machine HARDOX 400 and 450?

Can a 60° bevelled edge with a length of 3-4 mm be applied to the inside and outside of a pipe using an edge milling machine?

64301008010, Fräser, 64302011010, Wendeschneidplatte, 64303008010, Führungsrolle

Can aerated concrete also be processed with the MKAS 355?

The MKAS 355 is not intended for sawing materials other than metal.
Sawing gas concrete also produces mineral dust, which is harmful to the motor.
The MKAS 355 cross-cut saw is not designed for this.

Can cast iron also be machined with the MKAS 355??

Cast iron can be machined with the MKAS 355
We recommend the mild steel saw blade 63502302000

Question:

Core drills with 1 or 2-speed gearbox. Which is better?

If core drilling is only carried out in the diameter range of 12 - 35 mm, it is sufficient if the machine only has one mechanical speed. This is usually approx. 450 / 500 rpm (KBE 32 / KBE 32 QW) Some core drilling machines are also equipped with an electronic speed setting. Here it is possible to reduce the mechanical speed by up to 50%. However, it should be borne in mind that a slower speed also means less motor cooling through the fan wheel (KBU 35 Q / KBU 35 QW). 2nd gear machines are used in the diameter range from 12 - 65 mm. The two speed levels of approx. 250 / 500 rpm allow the speed to be adapted to the core drilling diameter and are also significantly more versatile in terms of the material to be drilled (KBM 50 Q, KBM 50 U, KBM 65 U / KBM 50 UQW, KBM 65 UQW)

Question:

Where can I find the dimension for the distance between the center of the core drill and the front edge of the gearbox, magnetic base.

Do I need an adapter for my machine?

Depending on the respective mounting system of the core drill or core bit, FEIN offers the appropriate adapters and centering pins for both machines/core drills with 3/4-inch Weldon or FEIN QuickIN to switch to the other system.

Question:

Does FEIN manufacture its own core drills?

Yes, FEIN has been manufacturing HSS core drills independently at our production site in the USA since 1977.
Decades of experience from which you benefit. FEIN has had a strategic development partnership for carbide-tipped core drills since 1984.

Question:

Does Fein still offer replacement parts for WAP vacuum cleaners?

Fein used to sell WAP vacuum cleaners, but that was years ago. Fein no longer supplies spare parts for WAP vacuum cleaners either. WAP was bought by Nilfisk. If there is any chance of obtaining spare parts for older WAP vacuum cleaners, it is through Nilfisk. Please search for Nilfisk on the internet and submit your spare parts request there, stating the vacuum cleaner model number.

Does a FEIN core drilling machine require maintenance?

Yes, the machine should be regularly blown out and cleaned of swarf.
Check the coolant system for flow and blockages. Keep the magnetic surface flat and clean.
The dovetail guide must also be lubricated and adjusted regularly.
To do this, briefly loosen the worm screws on the drill stand, loosen with a rubber mallet and then retighten the worm screws.
Ensure that the drill motor of the core drill is at the same height as the worm screw to be retightened.
The dovetail guide is set correctly if the drill motor does not slide down independently or the feed can be carried out with a comfortable force.
