Fisch FSA-134664 Wave Cutter Forstner Bit, 40mm x 10mm

This is the best forstner bit I've ever used. I think the wave edge cuts smoother holes. In ¾ in. MDF (notoriously tough on cutting edges) I didn't notice any tear out. The carbide edge sliced the MDF and peeled it like an apple skin where other bits I've used have had a tendency to shred whatever I'm drilling in. The bit also worked great in soft and hard woods. It has stayed very sharp and cleans easy. I highly recommend these bits and would love to replace all of mine with this line of cutters.

This forstner bit is superior to other brands when comparing the clean cut of the bore. I prefer this design of the bit compared to those with carbide cutters which are more difficult to re-center when boring thru the workpiece.

In the last 10 years I have used many Forstner bits largely from a set I bought at a Big Box store. I have ordered 2 large bits from AMZ. All of those are in standard (inches) and none of them were Fisch bits. I needed a metric Forstner and this Fisch bit was the only one I could find. It cost a little more than I wanted to pay, but it performed so much better than any of the standard bits I have. I am seriously considering buying a whole set of Fisch Forstner bits. Longevity is unknown, but I suspect will be quite good.

I used this bit to drill 50+ holes in 3/4" MDF for an MFT (multi-function table) top I use in my woodworking shop. The bit cuts a very clean, square edge hole. It clears chips very well, therefore it doesn't heat up like lower cost bits. From the first hole to the last, the feed rate and shaving size was consistent. This bit did exactly what I hoped it would do and more. I'll definitely be able to use this same bit for more MFT tops, as the need arises. Now to build a set in different sizes....

Used it for a cabinetry project and this bit effortlessy produced holes with razor sharp edges in melamine coated particle board, no chipping or lifting of the laminate.

I was trying to drill 20mm holes in my bench top and every drill bit I used (three different ones) would get clogged and stop working. This bit cut through 3/4 mdf and 3/4 plywood like butter. I highly recommend it and anything in their line. Great design and quality.

Great forstner bits! Gives me the cleanest cut, and Ive tried many..

I was looking for a 20mm bit so I could do an extra clean mount of an electrical fitting onto a Pelican Case. This was the first time I had encountered the Wave Cutter, but it seemed to make sense: More cutting and less tearing. Perfect. I've since added six more Wave Cutter bits and am very happy with the results -- especially with plywoods and composites.
