Ronnie...heat it with a Propane Torch...just make sure that the Blade itself don't get too hot...just the Tang....this way you take some of the Temper out of the Tang so the Bit will drill through it...I normally drill mine before I temper them...but with a Hacksaw Bled...the temper is already there...but you don't need the Tang to be tempered anyways...JMO

   Your surpose to aneal the blade. Take the temper out and put it back in later after harding. But its is so hard beause it's been temper good for that kind of steel.  To heat will take your temper out which you don't want.You don't want the blade to change colors.  Cover the blade part the potters clay and only heat the spots you want to drill keeping the flame pointed away from the blade. Use just enough heat to drill you dont have to get it red. DON'T QUENCH IT LET IT AIR DRY drill holes.

That's right  crook you don't want to heat the blade and by normalizing it by air cooling it should get close to what it was before you heated it in the future if you want to anneal some metal like old files ect you want to cool it muck slower you want to heat it to a cherry red and then cool it real slow a cheap way to do it is use catlitter the bentonite works great I'd just cut the side of the bag open place the hot steel on it and lay another bag ontop it won't cach the bag on  fire itl just smoke alot lol an dost it cool overnight
