Dremel Accessory 9901 Tungsten Carbide Cutter Bit with Square Tip - 3.2 mm Multifunctional Cutting Bit for Rotary Multi Tool

I bought this to grind through a broken bolt extractor which itself had snapped in the bolt leaving me worse off than when I started. Sound familiar? I was impressed with the way this bit went through the hardened bolt extractor like butter. Once loosened I was able to drive the remains of the extractor out with a punch. I then continued to grind out the softer belt and best of all due to the accuracy with which I was able to grind the bolt outwards from its centre, the thread of the tapped hole was still intact and usable. Well worth the money and there's not a scratch on the bit itself so good for more mileage for my next emergency. Excellent.

Brought this to remove the locking wheel nut spinning collar after my Key broke leaving me unable to remove the bolt. When it arrived it didn't look promising as was smaller than expected (although to be honest there wasn't much room to work) however this powered through the hardened metal of the collar in no time at all, no sparks just ground away the metal.No visible wear on the tool either - 5 stars

I have always liked Dremel tools and have quite a collection in my workshop, all of which get used on a regular basis. I purchased this bit as I was working on a project which involved carving stainless steel. The bit was used in a Dremel rotary tool, did the job beautifully and is still sharp, exactly as expected from a company whose products are well made and trustworthy. These Dremel bits are tough.

Cuts quickly, appears to be fairly hardy so I expect it to last and it's small enough that it allows access to small places. I got it for cutting out motorcycle bearing races and it's very effective for that.

My #1 most used bit in my case. I've used this dozens of times on stainless 316, titanium, plastic wood and it's been great. Still performing like the day I got it 6 months later. It is quite aggressive tho and will chew right through softmatierals quite easy. It can also grab quite aggressively sometimes. Having said that it's still my #1 go to, all around bit, that lasts while doing a great job.

Bought the cylindrical version to destroy an extremely hard "easy out" bolt remover broken inside a bolt, and it worked, so I have no complains (it's tough and sharp and there is no heat), except that it is rather short at 38mm. However, in the same purchase from Amazon I also got the 'Yakamoz' carbide burrs set (same hardness carbide bits, great piece of kit) which costs £11 for 10 pieces. These 'Dremel' carbide bits cost £9 EACH so I am giving three stars because of the price.

Very good quality....I've been using it to cut off the drive shaft nut on my BMW ... Cuts through steel without any hassleI would buy again if i this one will ever go bad 🤣 without giving it a second thought.

I brought this to try and cut off my seized shock absorbers on my car. I wasn't really expecting it to be up for the job but it was. Saved me buying an angle grinder.

Pas d'arnaque ici, le produit est parfait pour ce qu'il doit faire.Excellente qualité et resistance.

Dremel går att lita på. Kanske lite dyr med tanke på att det är en liten stålpinne med en liten mängd wolframkarbid.

Mi sono sempre chiesto come sia possibile trovare su Amazon per una decina d'euro un'intera raccolta di frese in carburo di tungsteno con recensioni ondivaghe e pareri discordanti mentre invece questa fresa, da sola, costa più di 10€.La verità è che la qualità si paga.Usata per ritoccare la filettatura di un pomello di plastica durissima: lo ha macinato come fosse formaggio morbido su una grattugia, senza scalfirsi o danneggiarsi, consentendo un lavoro di fino.Se avete un Dremel, questo accessorio vi può essere estremamente utile.

Ich verwende den Fräser, um in einen Altbau Bj. 1965 die eiserne Metallleiste am Fuß von Türstöcken aus Holz auf voller Länge (80 cm) um ein paar Zehntel Millimeter "dünner" zu fräsen, damit die Türen besser schließen. Das E-Werkzeug ist ein gewöhnlicher Stabfräser vom Discounter. Das funktioniert sehr gut, die Späne fliegen nur so, kein Vergleich mit Schleifen oder Feilen. Hervorzuheben ist aus meiner Sicht die Standzeit des Fräsers. Nach einigen Leisten fräst er noch immer genauso gut wie am Anfang. Auch den ziemlich hohen Querdruck, den ich beim Arbeiten ausüben muss, hat er bislang problemlos verkraftet und ist nicht abgebrochen. Ich kann den Fräser guten Gewissens weiter empfehlen, er ist nicht ganz billig, sein Geld jedoch wert.
