[creekrocker]

what about cobalt bits. your opinions?

[cougarman07470]

HI DAN, I LIKE YOUR VIDEO ON DRILL BIT SHARPING. I HAVE BEEN RESHARPENING MY BITS FOR YEARS AND YOUR INFORMATION IS RE-INFORCEING MY SKILLS. I LEARNED FROM A TEACHER FOR AC AND REFRIGATION REPAIR, HE SAID WHEN YOU LEARN TO SHARPEN DRILL BITS THE REST OF THE COURSE IS GRAVY. HE WAS RIGHT AS YOU ARE. FUNNY I LIVE HEAR IN WAYNE AND I TOOK 24" OF WATER IN MY SHOP, SO I WILL BE SHARPENING BITS FOR A WHILE, THANKS TONY G

hey do you think you could do a video where you drill and you stick a metal pole in the things that comeo off the driller?

just to show how serious you can get injured from trying.

[modernblacksmith]

@rogantu sounds too dangerous

[rogantu]

@modernblacksmith ah ok

[Kraftsman100]

Perfect explanation of drill bit sharpening. I have done it for many years on a bench grinder but never on a disc. I worked in many shops and never saw one mounted to a motor like that. Nice! Have to find one like that.

[modernblacksmith]

@Kraftsman100 they do work well, but get at least a 12"

Good video man. Wax lube is really good for stainless, it melts when it should and runs down the bit into the hole. Not sure if you've done this, but if you have to drill stainless with a hand drill, a series of short bumps on the trigger works much better than turning the bit slowly.

[modernblacksmith]

@ArtistBlade1972 yeah, like walter coolcut, I try to avoid hand drilling SS but when i do I start with a small pilot hole

[slab698]

Just had a bit go dull and this was exactly what I needed, Thanx Dan.

[modernblacksmith]

@slab698 cool, that's what it's all about!

One more thing to think about, be aware of the fluid you use when drilling. Some are so slick they can impair the cutting process. Others are flamible or burn off leaving a puff of smoke. Wd-40, JAX 78, Liquid Wrench to name a few. Probably best to stay away from aerosol sprays.

[modernblacksmith]

@jameasun you'r'e right many fluids make drilling worse, (straight water can work better than some oils)

[jameasun]

Great vid! I wish all my employees has this skill in there back pocket.

[modernblacksmith]

@jameasun it's hard to learn without being shown a few times

[FRUNTCASTER]

Good intro to drilling video Dan. As a side, because of the tackifiers added to it (the oil is nothing special), I've found chainsaw bar oil to be an excellent medium for drilling. The tackifiers really keep the oil on the bit, instead of everywhere else. and a gallon jug would last a lifetime.

[modernblacksmith]

@FRUNTCASTER never tried chain oil before. if I need any cutting oil I usually try to use actual cutting fluid, it's cheap and mostly water. doesn't leave much mess behind

[FRUNTCASTER]

@modernblacksmith --- No doubt, I have used my share of water based oils for ease of cleanup. The bar oil isn't as messy as you'd think, and a little bit goes a long ways. Cleanup is a cinch with a little mineral spirits.

[3literv6]

thanks for the lesson! more how to video's in the future would be appreciated

[modernblacksmith]

@3literv6 some interesting videos coming as we're getting a little giant power hammer today! YAY!

[MrJohn714]

Great vid! ...As a custom knifemaker who drills a lot of stainless, nickle silver, brass,etc. I most always use a little WD40. I find that it does three things, makes for a cleaner hole, keeps the bit from binding and cools the bit. I also sharpen my own bits the same as you using a disc.

[modernblacksmith]

@MrJohn714 I do a .little with SS but not too much of those others you are right about making better holes and especially on very deep holes it's good to have a lube to help the chip slip out, I use rapid tap or a coolant mix for stainless

[gerardopenya]

ho Man!!!! tank you very much for this lesson!!!

[modernblacksmith]

@gerardopenya you're welcome

[ericallandale]

I was shown how to grind the back slopes down then grind the centering flats to a proper angle between 25 to 30 degrees, then fine tune the drill bit.

That was a master mechanic who taught me that circa 1960..............

[modernblacksmith]

@ericallandale seems everyone has they're own way, but most folks were taught by someone showing them.

[irishfan84n]

Great vid man!!! Very educational!!! 

[modernblacksmith]

@irishfan84n cool glad you liked it.

[slipdisc]

All great advice. Thanks man.

The new camera footage looks very nice also. Although it doesn't fill the entire frame.

[modernblacksmith]

@slipdisc yeah,, that was because the file was so huge at 25 min long but I need to experiment a little, I think I need to upload it at a lower resolution but big enough to fill the frame.....

[ASSMYLICK]

thank you for doing Videos like this. i learn allot from them and it makes me envious about you having the workshop but i know that with time i to will get one.

[modernblacksmith]

@ASSMYLICK you can find a little drill press like this one for $40-$50 they're a dime a dozen just keep your eyes and ears open for one.

[blacksmither537]

im the second....lol uhm at 14:56 I aint heard ya say nothin bout oil when drillin..??? thought I seen some drippin off your pilot bit though.... by the way think your doin a great job on your videos...this one rocks!!! Salute yeaaaaa!!!you did touch on it...

[blacksmither537]

[modernblacksmith]

@blacksmither537 I very rarely use oil the really is no need except above 1' holes or if trying to do production drilling. or drilling hard metal

[modernblacksmith]

@blacksmither537 I think you were seeing a little glare off the shiny part of the drill. or the little pilot drill I was using had a double step to it like a drill with a pilot drill built in.

[Lakesideforge]

first coment and view!

[modernblacksmith]

@Lakesideforge there is no way you had time to watch this whole video!!!
