Not sure if this is the way to drill holes?

[luvmytoolz]

While perusing ebay to stock up on cheap 1/4" 2 flute router bits, I came across this seller that has a novel way of using two flute TCT router bits in a hand held drill!

I could be wrong but I strongly suspect this might not be OH&S approved? ;-)

It's a way of drilling a hole in SOMETHING.

Whether it's what you intended to drill the hole in is another matter entirely...

Not sure if the use of a router bit as a drill is OH&S approved or not, but the use of a hand to hold the block in the way shown is probably not. [big grin]

A better way would be to hold your hand under the block so you can tell when the bit’s come through.

Or just leave the wood out of the procedure altogether - no point in wasting material.

I routinely use cheap V and U bits in drills for countersink holes at very low speeds. They work as knifes at that speed and last an eternity in laminate - compared to the "official" HSS countersink bits for drills.

As for using a proper big router bit in a drill ... well ... Euclid got it right on that one.

V and U cutters you can get away with as they balance on the centre, a 2 flute router bit on the other hand....I wouldn't want to be standing near it when it immediately grabs and sends the drill flying!

Worked with a guy drilling into aluminum storefront framing, drove a drywall screw through the extrusion and through his finger and out the nail.  Pretty sure it hurt worse backing it out. This was back in the early 80s 2 or 3 hours from shop. Doused it with alcohol, not the drinking kind, wrapped a paper towel and duct tape and carried on. Also in 80, I was making hand mirrors for Christmas presents.  Used a small cast iron frying pan as a pattern and was routing out the round recess for the mirror.  This was long before the 16 routers I own let alone experience using them.  I had a mlling bit in my Craftsman drill press doing the cutting by hand, no jig...stupidity of youth and inexperience.  Bit grabbed and I ended up with three shallow perfect angled cuts in my thumb.  My reflects were much better than my judgement thank heavens.  I still have that 15' drill press and used it for years milling aluminum with a Grizzly cross table.

I nearly spit water everywhere on [member=75780]woodbutcherbower[/member] comment, then [member=42852]Euclid[/member] topped it.
The real problem, other than the obvious dumbness of the whole thing, is that it's not even a plunge bit. If you had the block perfectly clamped in a drill press and tried it, you're going to make a circle and smoke.
Sadly though, people do stuff like this.

Where the heck did you find this little bit of marketing genius?

Just when you think it couldn't get more funny, while searching for the seller, I came across this pic, the plot thickens!!

^ At least the surgeon will appreciate the nice clean hole with no tear out [crying]

Once the woodworking career ends, at least he’s got a future with photoshop.

Why GFCI outlets were born! [tongue]

As a side note, when I ran two 20A circuits to my shop bout two years ago, the code mandated that I use GFCI/AFCI outlets.

On the continuing subject of dodgy router bits, feast your eyes on this manliest of 1/4" shank router bits on Temu's site!

What could go wrong! ;-)

Looks great for applications in foam, to be honest.

3" cut length, 3/8" diameter with a 1/4" shank.....sketchy at best. In a groove like that pic, no, just no.

In foam, I would sill rather see spiral flutes to evacuate the chips. Foam grows/swells and gets compacted in the channel behind the bit, which make heat.  Foam also does not respond so well to the interrupted cut/slapping. It deflects/flexes away, so your cut may not be where you expect it to be.

Using the bit for cutting through the foam, would seem fine to me.  Some sign makers’ blanks are made from rigid foam, but the density of that stuff is pretty high.  I don’t know what level of resistance that foam creates.

I think an up cut would fling a lot more scrap than we are seeing here.  But I don’t have experience cutting foam.

 

[luvmytoolz]

It would work fine on HDPU foam sheet at a slightly reduced speed, (that stuffs a dream to machine), but normal foam as CRG says I could see it becoming very messy. It cracks me up though the seller thought to show the normal use as being a full depth slot in timber, I'd give it about 2 seconds before things got real!

The picture in your thread-opening post puts one in mind of the Kenny Everett character, 'Reg Prescott'...
