DRILL BITS : TITANIUM vs COBALT - which wud u buy ?

fed up of dem cheap HSS only dulling\breaking

wanna buy a set & yea i know i cud go read it online but i like to hear from u guys too


hopefully amazon have it sale soon ...

If you don't mind me asking what are you drilling on a daily basis, do you use cutting oil while drilling and do you do multiple holes in short time spans. If you do then maybe invest in a bit doctor and sharpen/ repair your bits.

[- Rovin's car audio -]

not for daily use but occasional use in steel like rhs , flats . angle iron etc

have owned titanium coated bits b4 which lasts fairly long but do get natural wear\tear & smaller 1s do break if u put too much force on it



time for a new set so i say let me try cobalt this time , did read up on it & they say its very tough

http://www.amazon.com/dp/B00004RGVZ/ref ... 3RU4&psc=1

never really used a proper oil or cutting fluid as americans call it , usually used some wd40 or car oil

want to try this & was about to ask ppl here

as for drill doctor , us$100-130 i feeling hard to pay that much when i can buy about 4 sets of titanium or cobalt bits for d $ ....

[pugboy]

are you drilling with slow speed or high speed ?
high speed will over heat bit and dull it fast.

also better to predrill smaller size because a large bit has a bigger chisel point which does not pierce well.

[- Rovin's car audio -]

slow speed & thats exactly what i do : start with a small bit then use d bigger bits

note that titanium is a coating eh so like all things it will eventually wear out

gonna try some cobalt bits this time yes ...

[[X]~Outlaw]

Forget the Ti coating. I use cobalt bits in just about every metal including Titanium and the work perfectly once you use the correct rpm and feed.

For steel use a sulfur based cutting oil.
For aluminum WD40 is great.

If you are drilling thick material use peck drilling..ie, drill in small depth increments and retract the quill to clear the chips.

One more tip, use a center drill to start your hole, that way the bit would not wonder at the beginning of the cut.

Morse drill bits are the best I've found.

[X_Factor]

Which ever bits you decide, they will all get dull at some point, and will either need re-sharpening or dumping...

while cobalt is the sharper bit and can tolerate the heat better, they can also break easily....especially using a drill with a non centered drill line....so if you really wanna spend some cash
get a decent set of cobalt bits and the drill doctor 500X
and that should last you for a really long while once they do not break
it may be hard spending the initial 1000TT for the combo but you have it for a really long time after
if not, continue with regular Ti coated stuff and change when they get dull

How much would a 1/2" drive torque wrench usually sell for locally? Harbor Freight has one for $10usd. Should work out to $200ttd landed.

[pugboy]

I have that torque wrench, it is pretty heavy, that is not a bad price landed.

it is quite popular, did a rudimentary calibration check and it appears to be correctly calibrated.

[pugboy]

I have a drill doctor, it works but only really good on bits over 3/16 or so
because it uses a special holder which has to be aligned before grinding and it does not hold/align small bits well.

It also sharpens with a large chisel point

Does it come with a storage case? It looks good but I don't know what these sell for locally to tell if I'm getting a good deal.

BTW how did you do that calibration check?

[pugboy]

yes, comes with case
to do a basic check you clamp it in a vice horizontally and hang a known weight from a known distance to check the lbs/inch, google

Muchas gracias señor.

Location for Tools store in duncan village from de highway?

[X_Factor]

got time off to buy a gift for a co-worker who has been transferred visited the 2 main tool places in san juan district...and say lemme drive down bhags just for so...

to my surprise today bhags prices have subtly increased in becoming more expensive than other establishments

Where can I get a good drill press

[Chimera]

Does anywhere down here sell sod pluggers? I want to try to grow a zoysia lawn from plugs

[nervewrecker]

So today I finally got the chance to use my klien mm200 dmm and for some odd reason it does not read zero on the DC voltage. I got some crazy readings from a 12v source and another cheaper meter works fine.

Reporting back on this, was a blown fuse. Just changed it and it works fine now.
Got a replacement for $5.00 at r and n in sando

Check tool house in duncan village.

[X_Factor]

for diy stuff, the skill that was mentioned above will work fine, good bits and some cutting fluid

for machine shop biz, you need something better

Anybody bought a cordless hammer drill lately ?

It appears all the manufacturers seem to sell batteries separately now.

[- Rovin's car audio -]

home depot has a few nice deals going on now even cheaper than amazon , so anybody have family coming down check it out online ...

[pugboy]

I was there last weekend, they didnt have any cordless hammer with batteries
Only without, even the ryobi which they seem to push.
Ebay is a better bet now.

[pugboy]

A guy was telling me the new green ryobi is good as they were bought out by the same company that owns milwaukee
