Recommend a good quality large size drill bit set

[BigBlue1]

I have a decent quality hole saw kit like this:

Those annular cutter or Hogan Rotacut kits look nice too. Probably hold up a whole lot longer than a standard hole saw blade. I may have to consider that Hogan kit...

Rob, here's a few "helpers" -

BTW, your 300 rpm DP should be good up to a bit over 1" annular cutters (with coolant, anyway) - my Hougen 917 mag drill manual (that model has 2 speeds, 250 and 450 RPM) says to use the lower speed for cutters over 1" diameter.

If you find that you need to drill much stuff that will NOT fit in a DP, an inexpensive (relatively) mag drill might be your best option... Steve

Well I'm cheep/frugal! What I did to slow my drill press down was to weld on the largest "B" pulley I could to the bottom of the quill? pulleys. I then ground out the smallest rib for the "A" belts on the intermediate?middle pulley so that I could run a "B" belt in the bottom grove. I just use an "A" belt off the motor and I still have a few speed options there. I "lost" a few speed options on the last set of pulleys but I never used them anyways.

An easy way to slow down a drill press is to buy a small 3 phase motor and a VFD,
if you go real slow add an auxiliary fan to cool the motor.

pms you may be cheap/frugal but I am embarrassingly lazy.

I have a few cheap DPs set up at different speeds and I NEVER change belt adjustments for speed even when I should.

Good practice? NO.

Lazy? YES.

Additional MILLER Time? Yes

Here's another way to slow a drill press down,

But, my big one slows down to 120,

so I've not altered the others that I have...

If necessary your DP RPMs could be reduced by adding a jackshaft assembly.

Love your jackshaft, BB.

I have the same setup (Weldon adapter, MT3, Champion annular cutters, etc.) with the same drill press. My DP came from HarborFright years ago, and it was the biggest belt driven unit out there. Still too fast at 180RPM IIRC. Way less money versus a sweet gear-head DP like SAWYER's.

Anyway, I have not slowed my DP down (yet), but I have a 2-speed washing machine motor that I scavenged just for that purpose. Did you consider a slower motor instead of a jackshaft?

As for the OP's Q, I have the Silver & Deming HSS set, and it is lousy. If made in M42, it should be much better. I have M42 64-piece bit sets from HF, and they are pretty good. Best bet for me was annular cutters, tho I also have some hi-quality MT3 taper bits, made in USA, up to an inch. Mostly purchased used on eBay. Bi-metal hole cutters work, too, but you really need to get speed below 100RPM.

Good advice. I should have bought one 20 years ago or at the very LEAST when you first got your Hougen.

Thanks Dave. I did consider a slower motor but only briefly. I did the jackshaft mostly because I used stuff on hand. I had pulleys belts and shaft but for some reason no pillow blocks the right size among my stash.


And I agree. Sawyer’s would be pretty much one of the best ways for drilling big holes with a stationary machine.

Since installing the jackshaft I ended up trading an electric bike for a Bridgeport clone.


Now any NON Mag drill annular cutter use is accomplished with this. Benefits are large table for clamping. Infinity variable speed and power feed.
