i recently purchased a Harbor Freight Haul Master HD trailer (1720 lb) I need it for hauling rental equipment, specifically hand lifts/trenchers to the job sites etc. I purchased a bunch of stake pockets and need to drill holes in the frame to mount them.

 

I purchased a Uni-Bit and got through 2 holes with ease using wd-40. Well i ran out of wd-40 and i cant help but to think there has got to be something specifically made for drilling holes. I need something i can pick up tomorrow morning at HD/Lowes/Tractor Supply etc.

 

A quick google search brought up thread cutting oil but im not so sure i can find that locally.

 

Help! i know theres alot of guys on here that work with steel. need the trailer finished by friday for a trencher im picking up so i cant order anything. I guess if theres nothing locally i can just go back to using wd-40 :o i have 30 more holes to drill :lolsmack:

 

TIA!

Like you said cutting oil....or 3-in-1 oil works just fine. We (well, not me anymore) do alot of drilling and this has worked for me that last 16 years :). I'm sure there is something "better" out there, but it cut's down on the friction and the heat enough in my applications. I just hold the bottle next to the drill bit, and squeeze it when I need it.

 

Keeping the drill bit sharp is the other key factor......if they are junk bits, keep a few handy and just use a new one when you feel it isn't cutting correctly. If you have a sharpener, they work to. But Harbor Freight has throwaway bits.

Good find Chris...looks like it's in store and cheap also....

 

Depending on what size, you can also get a 10 pack of "high" speed bits for like $8. I would assume they are garbage though, but that's the point.

My wife tells me I should work in that store.

 

Haha, you should man. Everytime I go there, it's a PITA to find someone to help us out. It maybe a local anomily, but I always end up back at Lowes. :cheers:

Magic tap is something we sell and works well.

If you ever get in a bind and need something, a mixture of soap and water can be used. I'd prefer that over any oil / solvent not designed for heated applications. Some of those chemicals can become quite toxic when heated.
