 Hi Rob

I have a drill doctor it's a nice bit of kit does a good job, but if you can re grind a drill by hand and only have an occasional need to sharpen a drill you have to ? The expense

Hi Stew

Its mainly for smaller drill bits Stew ,say under 5mm , my eyes seam to be a bit naff at the moment ,(must go for an eye test) , I am fine grinding 6mm and above by hand no problem , its just the smaller sizes  :palm:

Got one Rob and it's a good gadget. Mine does upto 13mm but they can go larger with bigger collet ( which I forgot to get when on hols in USA - bugger!) :hammer:

Really fancy Stevensons magical drill sharpener as demo'ed at Donc by  a shifty looking bloke in a jumper :lol:

John was showing it off for Arc euro and I recon it's a marvel but wasn't totally sorted at the time. Ketan maybe able to update us on that one?

Rob:

I have one with the collet to go to 1/2 in.  (Drill doctor).  It works quite well if I do my part and I understand (but have not tried it) that by holding really small drill bits in a pin chuck it will work with smaller bits than advertised.

Mine needs another diamond wheel - I found a very basic one missing a few parts but with a new wheel - at a thrift shop recently so just need to change it over.

I have had a Drill Doctor for more than 20 years.  I have the collet set for it that will locate a 3/4 inch drill bit.  I do not use it on bits smaller than 3/32 inch.  [I have a "hand guide" set that will take me down to .005 inch bits.]  The biggest hassle with the Drill Doctor is getting the "fingers" to grab and orient the bit properly -- it often takes me several "tries" to get that right.  As I live just north of the factory, getting parts is not an issue for me.

Does it matter which drill doctor? There seems to several models.

Is this fine for home shop needs?
http://www.drilldoctor.com/drill-doctor-750x.html

Does it works right out of the box and "as seen on TV" or should I buy some other bits as well? 2,4 - 19 mm Dia range seems pretty good for me.

How long does the abrasive wheel lasts? Should I get another as well?

Pekka,
One individual over on another website asked about wearing out the wheel prematurely, my curt response was dont be so heavy handed........but he deserved it.... :coffee:

To answer your question in a more polite manner, it wouldnt do no harm buying a spare diamond stone for it if you think it will wear out.....I didnt when I bought mine, but I might just do that now....
That said, there isnt a lot of dust produced from touching up drills......

Good luck with your purchase... :beer:

I've also read that the wheel can be turned around (it's a small cylinder) so as to use the other end if it has been used for small drill bits for most of it's life.  The larger bits use up more of the area on the diamond wheel so preclude doing this.

I'll take a look at mine later today and report back.

I've used one - biggest disappointment for me was how fiddly setting drill in position can be.  As Lew mentioned it can take a number of attempts.  Much easier to set for slightly larger drills.  It is perhaps better than my old Martek, but not hugely so.

Just checked to see if reversing the diamond drum would work.  My drill doctor is the 500 - so good up to 1/2in bits.

Both a 1/4 and 1/2 in. bit reach to the rear of the sharpening drum so reversing it should work.  Mine needs a change although visually it looks good compared to the new drum.  Feeling it reveals that it is now very smooth at the back and less so near the front.



It's not easy to see however this is a 1/4 in. drill bit reaching near the back of the drum - this is similar whether set up for 118 deg. or 135 deg.

Have any of you used it for split pointing bits?  I've never tried that and would have to look at the instructions to see how.

Splitting points goes by feel, take it easy. If there is not enough clearance on Your drill bits, just turn the bit clockwise when looking at the cutting end of the drill bit, hope I have the direction right as I am not in front of the machine and am ASSUMING My memory is correct.

Slight hickup....found good prices including P&P and all....but they were US half vlotage models...european 230VAC/50Hz models seem to be somewhere 270 and over 300 in Finnish shops. At that price point it does not make sense.

Few amazon searces more, but it looks like I'm going to ditch it. I thought there finally would be a touch up tool to keep all drills sharp.

I got mine on holiday in USA and got a 110 v converter for it. Most work sites in uk run on 110v so they're available, mates in Denmark use 110 volt stuff so must be available on continent.

Wish I'd got the bigger collet as getting one here's a problem. Meant to buy one in states but forgot! I got the 750 model.

Did get a spare wheel but  must try to be less heavy handed as there is a tendancy to push the collet into the machine when using it ( might just be me though!).

Thank you  for all the comments and advice  :thumbup: ,  mmmmmmmmmm maybe I should just bulk buy the smaller sizes and just bin the bit  once dull , it just seams a bit waist full .



I will think on it .

Thanks Rob

John, I have been loaned a drill doctor on long term. My mate has acquired a proper Union tool and cutter grinder so doesn't use the drill doctor these days.

I sharpened a couple of old sets of drills with it and was quite pleasantly surprised at how decent a job it can do.

I did split the points on the drills over 4 mm dia up to 13mm and it does that very well also.

In essence there can be a bit of fiddling about to get the drill set up and indexed properly,but for the price of the unit they do a good job. Most certainly a huge improvement over the old Martek that I used to own.. As a couple of others have said previously,be gentle when feeding the drill into the wheel and don't lean on it or the wheel life will be dramatically reduced.

I do wonder whether the wheel might also benefit from being occasionally de-clogged by using a diamond wheel cleansing stick.......OZ.

ETA: I also meant to say that small diameter drills(1-4mm) are often so cheap to buy in packs of 10 that they aren't worth the hassle of re-sharpening

Rob, again referring to the mate who loaned me the drill doctor. He sharpens small drills with the dremell and a diamond cut off disc. He wears a pair of binocular magnifiers when doing this to be able to see the tip clearly. It is a very successfull technique......OZ.

Rob,being able to clearly see what your doing is more than half the battle won.

When I say he uses a diamond dremel cut of disc,he is using the cheek of the disc rather than the edge.....OZ.
