The Forstner bit of Famag runs smoothly, the cutting area is razor-sharp and the diameter of the drilled holes is exactly 20mm. As far as ever not bad. However, I thought in the first hole to have drilled in the wrong timber: the Forstner bit bored into the wood (MDF) as in warm butter. There was simply no stopping them. Anyone looking for a good Forstner bit that holds even long, is well advised with this product. I have therefore drilled some holes and confess for testing also partly with the router. I wanted to know it simply: after 20 holes with the router it still works wonderfully. A strong buy recommendation.
