I have lots of dull drill bits in my tool box. Right now, when my drill bit gets dull, I buy a new one. Can drill bits be sharpened? What's the right procedure and tool?

hello bro,
drills can be sharpened, it will just take training but its easy,for a meantime whenever you need to use again your dull drill bits why not bring it to a nearest machine shop and ask a machinist to sharpened it for you and observed and ask how he do it, that way you can see how and learn how and then practice it yourself, you will be needing a pedestal grinder a small one will do.or check any machinist book and look for how to sharpened tool bits

The sharpening can be done by anyone as long as he keeps in mind the angle that the bit has to be ground down upon. this is different, depending on what the drill bit is used for (material wise)

Usually if it is for wood & steel use, I buy a new one. If it is for masonry use--I sharpen them using grinders or kikil. I think the drill bits for steel are the expensive ones..I dunno if i'm right on this one though.

sharpening drill bit needs skill and a lot of practice. you need a bench type grinding machine with a good grit of grinding wheel with safety features. pero ang pinakamadaling paraan ay maghanap ka ng machine shop na malapit sa lugar nyo, o kaya ay maliliit na talyer na may grinding machine at paki sharpen mo na lang sa kanila then bigay ka na lang ng pangmeryenda.

kasi kahit na may grinding machine ka and you are not familiar in using it mahirap din. kasi different drill bit type different angle ang kailangan.

and to prevent the drill bit from getting dull, you need to use different drill speed for a different type of material to drill. example when drilling aluminum you need to use a high speed, for mild steel you have to set it on medium speed and if for hard steel you use low speed.
just my 2 cents.

I never developed "the touch" too impatient I guess. A few months ago I found this jig for sharpenning drill bits with a bench grinder. Check your local industrial suppy. If you don't have a bench grinder I'm sure you can use an angle grinder with an appropriate stand of some kind, or even a sander polisher.

The jig may seem pricy at P450 but consider that a 12 mm Dormer costs P150. Since I have quite a few drill bits, the jig immediately paid for itself ... now I figure I'm making money.

Can the jib be used with a handheld grinder instead of a bench grinder?

Thanks

You'd have to make a mount for the grinder so you can fix it to a table with the disk perpendicular to the tabletop. A drill with a sanding attachment would also work I think.

I agree with benji, you just need to know the angle that the bit has to be ground down upon, and use the bench grinder to remove steel in the right places. Doesn't take much skill, just a bit of practice. But remember that these bits are heat treated tool steels, and grinding them will overheat the tip, causing it to lose its hardness. This is called "tempering", or drawing back a bit of the hardness so the steel can become less brittle. Over tempering destroys the steels hardness, so I suggest before the surface becomes bluish to purple, dunk it in a pale of water. Be sure to do this before the discoloration happens, or you'll render the bit useless.

I hope that helped :)

I m quite glad that there are folks too who share the same predicament as mine on how the hell in this world could we sharpen dull bits with just a few skills and a costly jig

Yah, I agree of what you said that the sharpening jig may be pricy but its worth the cost since you will still be using it in the future on other dull bits.

If you would not mind would you please share me the name of this sharperning jig and of course the hardware store here in the city where you could avail of such.

Hello brod,

if you dont mind, would you please mention the name of your jig and the hardware wherein i could buy such thing

tnx and more power

I like the way you count your "profits". :)

Yes please (im bumping this), like everyone else here could you tell where bought this jig? I like one also.

Thanks bro. Yup it is still making me money.

I bought mine from MyTools just passed the Cainta Junction heading towards Antipolo. I'm sure you can get one though in Binondo.

I got one of this based on Incc63 recommendations. It does work but has a learning curve too. For an impatient guy like me it surely is better than freehand sharpening on a bench grinder. Anyway I got my bigger bits sharpened. I just can't get it to work properly on the smaller l bits.

No problem for large diameter bits but for the smaller ones I can't seem to get it right so I just buy new ones instead of sharpening.

thats nice, coz its effective too...

if we are always drilling metal, kailangan natin ng sharpener :D

I find it hard to justify buying a drill doctor, although I really think it is a very nice tool to have and use as I have a bunch of drill bits.
baka pwede maki-sharpen na lang Ossie sa susund na eb... :D

Yes I have one too, same as sir jayL's and its just perfect for sharpening my dull drill bits but also
thinking of buying a new one being sold at sulit and simply compare which of the two will be easier
and faster to use.

no problem master timb.

but if you are really into metal working, its a must to have IMHO. :)
