mag drill

mengele

was thinking of buying one to drill through RSjs etc. What would I need to be spending for a handy one. Would be rarely used afterwards but would be handy to have one when needed.

I think you'd be looking at at least €500 if not more unless one pops up secondhand on eBay or donedeal . If you hadn't alot of use for one they can be hired and it could be the best way out cos they're a tool that alot of lads like to borrow /break !

Yea they come with a chuck for normal bits, the speed on most of them can't be changed, so it's simply on or off, mightened be to suit some drill bits, so a cutting fluid and a light hand would be required in that case.

This is the same model but cheaper

I have a different model alfra rotabest and find it good, no problems with it. She is rated for 35mm holes.
I also have another mag drill which is rated for 50mm holes.
I have a tendency of using that more as it has a stronger magnet and more power.

Good mag cutters will cost about a euro a mm, so a 25mm cutter will cost 25 euro.
It sounds expensive but take care of them and use coolant and they will last.
Also when you start using a magnetic drill its very hard to go back to using standard drill bits

I have a mag drill. Got it free from work (Part of production closing down). Some guy borrowed it before I got it and messed up the chuck. Its now running with a slight wobble. I must try and source a new chuck.
They are a fine job to use. I drilled 15mm holes through 100mm thick mild steel no problem. Easy to use too. Ordinary drill bits are fine, but you need to use some cutting fluid or paste and most important of all keep the edge on the drill bits. The speed on mine is constant too.

30 or 40 quid would hire one for a day but you generally have to buy the cutters but they will last.

I got a chuck to suit my pillar drill so I can use the mag drill cutters in both drills. Hate normal drill bits they are always blunt when you need them.
I got a big job lot of cutters on ebay.
Think my mag drill cost me 300 back in 08.

'Broaching Cutters' isn't that what they call them. I haven't used them. Handy skill to be able to sharpen your own drill bits. Easy enough when you get the hang of it. Some good videos on youtube.

Yeah broach cutters. When you are drilling any big holes they really show there worth. You have to start with a small bit and work up with normal bits. But these just cut a 1mm circle so way less work.

That's the mistake most people make, you don't start with a smaller drill. I used to do that till an experienced machinist told me one day that I should only use the one drill size. If you put say a 10mm drill down on a 5mm hole, then only the outer 5mm is cutting . That ruins your drill bits.

I bought a Rotabroach Panther a couple of years ago after researching mag drills but haven't used it much yet, I was going to buy a pillar drill but thought this would be more versatile, I have a frame made up for the vice to drill items that are to small for the magnet to catch.
One of the reasons I went for the Rotabroach was you could slow the speed when drilling, if I was buying one tomorrow I would go for the Rotabroach Element 40 as there is a different way to alter the speed, on the Panther the speed is altered by slowing the motor and on the Element it is done using gears. I bought the Panther a year to early as the Element range is only out about a year

The Panther is on offer at magdrill.com at the minute

I have an adapter for my cordless drill to take broach cutters. Best thing ever.

Would they be hard on a cordless ? What size would you go up to with it ?
