Drill bit sharpeners

Just looked at their web site... looks like a good bit of gear. Much better than alll the sharpeners I have ever owned... and thrown.... lol...

What store carries them? $$$$?

Gadgets like the drill bit doctor work fine. Used similar in another life ha ha

The ones we had in schools only handles up to 12mm I think.

Be sure to check that any you buy can handle the larger sizes if you want 16mm.

To sharpen a 16mm bit in a drill doctor takes a 1/2 hr or more.
The machine you need to sharpen a 16mm bit is the largest one and its about $450.00 - personally I'd rather neck myself than stand around trying to sharpen larger drill bits on one.

Tool shops have a drill bit sharpening service.... or.....

Pay $75.00 and buy a step drill.

Hi,
just remember, 118 degrees included angle, (for Steel), backed off for Brass, and allways keep the chuck end beneath the grinding wheel when sharpening.
That will allways be in my mind.

G'day Beatit
I have an el-cheapo unit at home that I've used successfully a few times. Bit fiddly to set up but works fine.
Can't recall what size it goes up to - can check that and make tonight if you like and let you know. Would have bought it at a hardware store.

See step drills here Cost a bob or two or three as well... lol ..

G'day Beatit,
We have a Drill Doctor here at work and it seems to work fine although it is still relatively new. The trouble with these sharpeners is the grinding wheel wares out of shape.
Being an old (well, gently ageing) Chippy, I use the side of the bench grinder. Starting at the cutting edge get the pitch right, twist the bit and lift it up in the same motion so the back edge is ground slightly lower than the cutting edge. Dunk the bit in water to keep it cool or it will go blue and will not hold it's edge. Repeat the other side.
I find the bigger the bit the easier it is to sharpen.

I too have one and its good

I have had one now for several years and I had same problem now it is set aside a couple of hours and sharpen all my bits along with son inlaws as well you will wish you purchased it years ago.

Gee, lucky me!

Sharpening drills was one of the first things taught to me way back in my apprentice days. Don't need anything other than a grinding wheel.

$500 for a drill sharpening aid? ha! ha! ha! ha!

Sometimes a different angle is required, depending on what you are drilling.

Perhaps a new set of drill bits is the better solution for normal use, especially for the smaller drill sizes.

just take 3 or 4 bits and throw the busted ones away, smaller than a sharpening thing and so much less pain in the arse

Yes I bought a Drill Doctor 750X from this mob (www.HardwareSales.com) in the US last year. Much cheaper ($US140) and delivery was in 3 days form the US and cost $US40.
I also bought a couple of spare diamond wheels for the unit as well. Total cost was just over $au200 delivered.
I then bought a 300w 240 - 110v transformer from this seller on ebay auction number 260538627721.
So the whole shebang was under $AU250 and I've since sharpened hundreds of blunt drills, mostly in the larger sizes up to 3/4".
Takes only a few minutes each bit unless it is broken/chipped in which case I do it roughly on the bench grinder and then on the Drill Doctor.
I reckon I've got my moneys worth out of it already as one 3/4 bit is at least $20 and as I said I've sharpened probably well in excess of 200 bits and am still using the original grinding wheel in the Drill Doctor

Hi Beatit

I have no knowledge of these machines, but as the other responses suggest, they work but are pricey.

Do you have a friend or neighbor that happens to be a fitter/machinist/boilermaker? Any one of those tradesmen could teach you how to sharpen any drill with just a regular bench grinder.

Yup, drilling with a blunt drill bit is really a pain....

Good luck

Dave

Like sandman I learnt the drill sharpening thing as an apprentice Fitter many years ago. A 4'' angle grinder will do me to get an edge on the job if there's no other way. It's a skill and there is a knack to it. But like someone else said keep the chuck end down and keep the angle and the distance from the point to the edge the same and you'll get it. there must be some websites that can explain it properly.Buy an 8mm drill bit and just keep sharpening and trying it until you get it. Give it a go

G'day guys,

Thanks very much for your feedback. I may look at buying overseas and thanks for the heads up on the transformer. I may also try sharpening via the grinder but I'm guessing that the 118 degrees will be a tough one to get right. I must confess that doing my chainsaw has been a hit and miss affair but every now and then I do get that right.

Once again thanks a lot

Kind regards
