Drill Bits
There two types of drill bit for steel. 135 degree and 118 degree. Most stores stock the 135. For mild steel which is best 118 or 135?
Thanks |

Re: Drill Bits
I have always found Hanson High Speed Steel drill bits with the 118degree included angle to be excellent. Don't even think about carbon steel drill bits. Cobalt drills are also excellent. Just for the heck of it go to the MSC site and read up on what kind of drill bits are available, what they are used for and what they are made of.

Re: Drill Bits
Often the geometry refers to drilling sheetmetal with the lower angle being preferred.

Re: Drill Bits
Any welding supplier or industrial house will have bits that will more than meet the needs of any car requirements.

Re: Drill Bits
I see drill bit sharpeners for sale. What do you think of them. I think they run a little over a $100.00.

Re: Drill Bits
Like 48Flyer, I find the Drill Doctor to be a good machine. Be patient and follow the directions.

Re: Drill Bits
Correction to my post above. At Hershey, I've been buying bits from WINTERS Drill Bit City of Winnebago, MN. At Hershey, they're at spaces CB 83-87. Oh, I have a Drill Doctor too. I like it!
