Excellent bit for fine millwork - also good for aluminum

Typical excellent Freud quality - this bit mills aluminum as well as wood.  Cuts are super clean, no tearout when using the proper speed and feedrate.  Zero chatter.

I got this to cut a series of 2" holes through 1/8" tough steel plate, using a handheld power drill in an awkward location.  It took a while to cut (using plenty of cutting oil and going slowly) but made consistent, clean holes time after time.  The bits still look great after 15 or so holes.  The pilot drill cuts quickly (although I found it was even faster if I first drilled a 1/8" guide hole).  The rim that keeps the bit from punching all the way through the hole is *genius* - makes it way easier to finish the cut, because you don't have to worry about the bit plunging through and damaging whatever's behind your hole.  My only complaint is that the spring that ejects the blank is pretty strong, and you're pushing against it the whole time in order to hold the bit against the cut, which is extra work.

I purchased this bit to bore through 5" pressure treated landscape timbers. I used a 1/2" drive electric drill with a side stabilizing handle. This bit cleanly chews through this pine material without any problems. Given the high rosin content, I occasionally had to withdraw and tap the bit to clear the chips that had adhered to the auger tip.

This countersink leaves a very smooth cut in all harder grades of aluminium like 2024 and 7075 with no chattering. The coating works well and the bit appears to be lasting well so far.

Good quality bits, everything was well-machined and was better than I was expecting.

I purchased the 1/8" straight flute to drill out a broken bolt for a skid plate on a pickup.  It worked very well.  I had a small pilot started with a regular drill bit started, then went with the Kodiak straight flute.  It took a little bit to get going, but once is started cutting and burring it went very well; better than  any drill bit I tried, including a cobalt bit.  I was able to get an extractor inside the broken end pretty easily once i had a deep enough hole with the straight flue.  I think finding the proper drill speed is key.  Very good tool; won't be loaning it out for fear it may not return!

After using this deburring wheel for a while now, I realize my fab life has notably improved forever. This is an essential item and wish I would have known about this wheel sooner. Works great for metals (personal experience with steel, Al, Ti), plastics (acrylic, polycarbonate). Actually pretty aggressive material removal for a fine grade, but once you get used to the resulting surface finish, it's very useful. This wheel material fits midway between an Aluminum Oxide grinding wheel, and a buffing wheel. Great, now I need another grinder, lol..

This is a perfect companion to a set of heavy-duty Forstner bits... a necessary accessory for drilling long holes in, for example, lathe turning projects such as pepper grinders.  It fits the hex-shank of bits from, e.g., Lee Valley, and is very well made... the bits run true and smooth when used in conjunction with the extender.

Nicely constructed bit, no sharp edges, and an eggbutt type barrel where the rings join the mouthpiece to prevent pinching. Good weight and balance, and available in harder to find sizes.

This 30 piece set is great for doing fine detail work.  The bits readily grind down surfaces into desired shapes.

Very good value for an off-size large diameter bit; I needed it for mounting challenge coins.. The hex shaft is a huge plus. Keep the speed low unless you've got a press >1/2 hp.

I've been using the MF70 for about 3 months now for work (prototyping circuit boards and machining small brass enclosures) and for hobbies (fabricating/modifying camera parts) and it's been a good experience. That there are so many bad reviews is a shame given that more than half of them are from people who clearly did not know what they were buying, which is no fault of Proxxon or Amazon. If you want a mill that can fabricate parts larger than about 2x4", this is not the machine for you. Whoever claimed they were told that the MF70 is capable of fabricating AR lowers was severely misinformed and/or confused. No, of course you cannot mount R8 chucks or standard-sized end mills. This *is* good companion mill to a big Bridgeport for very fine tasks or a single mill for someone who only makes tiny parts or PCBs- understand that and you'll be much happier with this tool.

A couple notes for potential users-

Tiny (<3mm) end mills turning at 20,000RPM are very different than tens of mm end mills turning at hundreds of RPM. You'll absolutely want good ear protection as the noise this thing makes when working brass/aluminum/plastic is unreal. The chips that tiny, fast end mills throw off are awful, not at all like the big razor bits that come off a big mill- more like fiberglass-type shards that get under your skin and itch like crazy. Big shop gloves are too unwieldy for small work so I wear non-powdered blue nitrile gloves and those do a great job keeping my hands happy. The upside to small bits is that oil isn't usually needed when working aluminum & brass. I've never had problems with end mills overheating/binding on this yet.

Speaking of bits, it takes Dremel-type collets and therefore takes all Dremel rotary bits. But I don't recommend using those unless you're working with wood and absolutely need some oddball shape as they *will* overheat and bind and just don't cut that well. Stick with good end mills- the set that Proxxon markets is decent and McMaster-Carr has a great selection. Be aware though that the largest end mills that are useable on this machine are 1/8" or 3mm, limited by the size of the largest collets included. It may take actual Dremel collets but I haven't tried.

As a couple other reviewers have noted, there may be some backlash on the column (Z-axis); this is fixable with instructions provided in a previous review. It would be nice if Proxxon checked that at the factory but I would assume that those who are buying a mill are the type who are comfortable maintaining their machines- even a Bridgeport needs adjusting sometimes.

My unit has no issues with backlash on the X-Y axis but does sometimes need the table jibs tightened to prevent wobble if something is clamped in an unusual way. They make these user-adjustable for a reason.

The small size (about 1ft tall) and weight (about 15lbs) means that it absolutely must be bolted to a table for stability (the mill has holes for 1/4" bolts in the bottom). I got my hands on a cheap Ikea table and ran bolts right through the tabletop and fastened the legs to a wall with L-brackets. Don't let the small size of the MF70 fool you into thinking you'll be able to move it around and store it away in a cabinet when it's not being used; it does need proper support.

All in all, I highly recommend the MF70 - IF it's the right tool for your task! If you're just looking for a cheap mill and the price on this caught your eye, keep looking. If, however, you want to fabricate or modify things that fit in the palm of your hand- can't go wrong with this.

I bought this and the 828937 bits for making tea light and votive candle holders.  My 1-" bit held the tea lights a little to tightly, so I needed to drill holes that were slightly larger. The 1-9/16" bit worked out perfectly (this one was just a little too large), and cut clean, flat bottomed holes. I cut about 2 dozen holes in end grain and the last hole cut is as clean as the first. The cutting edges have also outlasted my Italian red branded 1-" bit, which dulled to unusable after 6 similar holes. Remember to slow the speed of your drill press or lathe when using a bit of this size.

Works great! I've been using with a CNC Router milling aluminum at a ratio of 10:1

I used this bit in a Festool OF 1400 router in conjunction with the LR-32 rail and created a replacement MFT/3 top.  This bit was used to drill 20mm dog holes through 1 inch thick MDF.  The router was set on the lowest RPM setting so as to not burn the MDF.  The plunges required medium pressure (I put my shoulder into it) but the bit did the job well, and most importantly made incredibly clean cuts.

I am an amateur woodworker so can't say how these compare to other more expensive bits. However I used the Ogee bit to edge profile a wood island top that had over 30 linear feet. This was Sapele which is very hard and is prone to tear out so I was a bit concerned. After some trial on scrap pieces to get router speed set properly the bit worked perfectly. It was sharp and precise throughout and looks to have lots more life. I was very impressed. Would recommend these bits highly.

I am pleased with this bit and was able to put it to good use drilling holes for panel-mount XLR jacks in 14 guage (?) steel.  I would give it a four-star rating but unlike the photograph, the bit that arrived is not a self-starting bit.  The tip is not sharpened to cut through metal.  This means I must use my smaller stepped bit first to make a hole and then switch to this bit to enlarge it.  It's not a problem for me, but if this were the only bit you ordered, it would not work to drill holes.
