Thanks Frank. What kinda dril bits are stronger than Cobalt???

nice work, Lewis!!

Heres a mower blade knife I'm working on, OAL is about 3inches    :D  
Jeremy this is probably the one I will put on the raffle table at Shawn's bunny hunt.  

Ru, what are toy using to drill into these blades??

yes I like putting several rivets as well as holes that take some weight off the handle and give the epoxy something to hold on to...I use a drill press at the lowest speed and whatever bits are laying around,I sure cleared that up for you didn't I      
Maybe your steel is not soft enough     :confused:

Well I am using a drill, that might be the problem. I just went out and bought some better Cobalt bits. I will see what happens tomorrow! LOL

Lewis, Ru is working with annealed steel, so that'll have a big impact on drilling.  Oh, and I like the serial numbers!  :D
Nice little skinner there Ru!    

Ok, this is killing me. I got 4 NEW coblat bits. They are RIGID brand and are the same brand I bought the first time that got one hole in the blade. None of these would even cut into the blade!!!!! It says its a cobalt bit on the package and I went SLOW as possible. Is there something I am doing wrong here?? That 8 bits I have bought and wasted now, I think thats up to about $25 just in bits!! LOL

Lewis,
If you're not annealing the steel, use a center punch to mark the hole locations. One hit only!
That will cause enough molecular upset to allow the bits to cut.

As everyone's just told you . .run the drill as slow as you can.

I just had to break down and anneal them. I really didnt want to cause that would just prolong them being finished and I am impatient! LOL

I will have finished pics of the three that I made tonight when my wife gets home with the camera tonight.
