Thread: About time the ryobi bench drill goes out the window

A magnetic base drill is no substitute for a drill press. Ask yourself what type of work you will do most of and then choose wisely, considering what the chosen machine can and cannot do. Things like drilling a round shaft or pipe and also the depth of cut.
I love using mag drills and rotabroaches, but I don't personally own one, but I do own a 2 good drill presses.

Bought one from Edisons on ebay. Sent it straight back as the rack and pinion looked like they were cut with a blunt chainsaw and they didn't align either. Pinion only half engaged rack and had uneven spacing between teeth.

Hare and Forbes are notorious for inflating the price on their equipment, even more so post COVID as their big gear sales are down and they are trying to make it up with their consumer lines. None of those machines will effectively run a 50mm rotabroach as the piddling little A section belts are usually driving off the smallest diameter motor pulley to get the speed down and cannot transmit adequate torque to allow the broach to bite properly. 50mm holes in 30mm steel is some heavy duty work and I'm not sure why a back yarder such as yourself would have that need to be honest. The only way you will achieve that benchmark is with either a holesaw (slow and inaccurate) or a superdrill type boring tool (accurate and faster than a holesaw, but somewhat tedious). A decent magnetic base drill capable of 50mm diameter holes will shatter your budget too and will not work on Stainless or Aluminium and will be questionable on thin steel (magnet holding issues).
You really need to decide what size holes you need to drill on a regular basis and choose your machine based on that. Personally I would rate the two H&F machines you linked to as regular 16mm hole capacity machines and occasional 22-25mm use (#2 morse taper tops out at 23 dia, but reduced shank will go a bit bigger), but your drill bits will need to be well sharpened and lubricant used.

Arboga radial arm drill - the baby one, only weighs maybe a tonne. Cost me $400. 4MT, can run a 50mm dia drill into 40mm plate, no problems, using power feed.

Good luck finding one though.

The cheap Chinese drill presses - take the claimed drilling capacity, assume that's for hardwood or aluminium, de-rate to 50% for A36 steel and you might not be disappointed.

I have 2 of them, one set up just for wood, the other for small holes up to 10mm, 12mm at a pinch. Over that forget it, the belt can't handle it.

Like all machine tools, the only way you get good AND cheap is to buy old, and wait for one to come along.

I found a couple nice machines on gumtree but im locked down to 5kms radius which is a pitty as one machine is 10kms away and the seller doesnt have transport to meet half way

I was really happy i got that hare and forbes floor sale but really bummed they pulled the pin on me, 10 hours later the add is still up on there web site so i can see consumer afairs sinking them a new hole on the 18th but for me im over it i just want the refund to be quick and hassel free

I cant really find anything 1hp-750w for my money that appears decent

One thing i wanted a drill press to do is make a sleeve 30-40mm tall ghat i could loctite a bearing in instead of making one on a lathe asi sold my lathe months ago

Got me a beauty tho i hope for other peoples sake there were not too many orders placed for the same machine

So i ordered a new capacitor CBB60 and it arrived today i installed it and the ryobi drill press kept spinning in reverse, i tried to cgange the capacitors polarity with no change i than changed the neutral and live but no change

Just now i dissasembled the motor and the motors shaft was installed back the front, i corrected the problem and she runs good now in the correct direction

Found a drill press for you

Thanks appreciate the help i'll see you in a couple hours when you drop it off in you're one ton commodore ute lol

Took a while to drill actually timed it 24mins using 600 and 900rpm, second hole took around 17mins 26mm hole TCT carbide hole saw from ebay on a 1/3rd hp ryobi

Can't imagine how much faster the 1hp drill press from hare and forbes would have been

After getting a gear head drill for a steal, I'd never go back to a belt drive. If you ever spy one going cheap, jump on it!

I had no problem with belt slippage only the motor stopped when i went too hard, cant imaging pressing much harder tho unless the hole saw spins at 50 rpm and just peels the metal out, the steel felt like it had a really hard layer within the thickness that probably took up most of the drilling time

Slow down Gazza, 900 RPM is a bit fast for a 26mm Carbide holesaw in steel, every reference I can find lists 600 RPM as the maximum and in your case running slower will be likely cut faster and improve tool life. A good cutting lubricant will help too.

I looked up hole saw speeds a few days ago and it said 2000rpm for a 25mm size i too thought it was a fast speed hence i started on 600rpm today but the hole saw was bitting down stalling the drill so i tried 900rpm it had more torque alot more power without the spindle stalling while still cutting

I only had probably half a kilo or less of down force

I think you miss-read the chart. Almost every hole saw manuafacturer is recommending 350-500RPM in mild steel.
