Drilling 7/32 in hole

[TDM]

I went ahead and ordered a 7 pc set of center points from Amazon for $18. I’ll have quite a bit of drilling to do on the trade gun kit, which finally arrived back home today. So I’ll give the center points a try. They should be in Saturday, which is good as my Wife is bringing my kit to me Sunday afternoon and stay a few days.

Always 'step up' in drill sizes ... as remember this ... the center of the drill bit does NOT cut!

And just how does the drill start to drill a hole if the point of the drill can't start to enter the material you are trying to drill??? The flutes can't do their job if the point can't penetrate the work material.

Just figured poster had some kind of typo or misunderstanding. I have started thousands of holes with center drills. The center or point of the drill cuts or starts the hole.

Center drills are very handy and also so are spotting drills - split point drills can also be used to prevent drill point movement upon entering the material if the drill is not too small in diameter, but they are best to be used with a center punch. When drilling a hole as close to the size you want it is best to drill 0.020" to 0.030" undersize then open that hole's diameter up to the size you are looking for. Rearming the undersized hole to the exact hole diameter is best but most of the time a drill sized hole is good enough.

Not a fan of Harbor Freight and the junk they sell, but for just under $8 for starting a single hole, might be a deal considering the grief if you mess up. Not my first choice, but way better than sticking your tongue out while you hope your wobbling flexible drill starts on location and straight

I had a job and needed a wood plane .I hardley ever need a plane so to do this one job I bought a H.F. wood plane for $200.00 and change. That plane is still in good working order today. I am one that generally buys quality tools but I feel I got way more that $200.00 out of it.
