Drilling RSJ and steel for bolts and fixings with a magnetic drill

[@Elfin4]

7:29 Robin, dont forget to use those safety glasses on your head to protect your eyes from flying swarf. That stuff will take your eyes out.

[@TheSudsy]

3:09 nice swimming pool you've built Robin. ;)

[@davidhoogewijs1718]

i have used these magnetic drills over and over again in many occasions while i was a contractor,i rented them for the day as i needed them,but these things are golden mate,they do a brilliant job :-),you can't do it more easy then this,keep it up you are a craftsman Robin Clevett

[@nigelwilliams7403]

Another excellent video. Having the right tools always makes the job easy!

Hi Robin, was watching old vid of you with Roger and ply rafter template you set up for skil saw with 30 rafters, Roger said to you, " aw I see, there's no flies on you"..when I said that to my mother, she was 70's at the time, she said " no, only dead ones"😉

[@adgeebike9173]

My mother used to threaten to throw people out of the window no matter how big they were when she was annoyed. She was 5 foot!

[@firsteerr]

i spent a summer when i was fifteen drilling two inch holes for my dad in the city , hundreds of holes every day for the six weeks of my holiday !!!

[@isyt1]

Looks like it would be good for safe cracking!

[@djvasforever]

Use straps not only for drilling upside down, but for drilling into a side as well if possible.

[@derekpbyrne]

Brilliant Robin seen a lot of these drills on site but never knew how quick and efficient they clearly are .... Noting the safety issues that you rightly highlighted from previous experience which is something that always concerned me as it is a heavy bit of kit. But fantastic to see it in use by and expert 👍

[@thetallcarpenter]

A very civilised way of drilling steel on site👊 Cheers Robin

[@ukconstruction]

Cheers Del!!

[@chriscollins1704]

You can also get twist drills that fit in a rotabroach chuck

[@chriscollins1704]

I've got a JEI minibeast. You can just about get it in between 2 joists. Plumbers and electricians are spoiled on my jobs. Got me out the shit a few times also like the job I'm on now where the position of a connection got messed up. Highly recommend

Beautiful tool. Learning tips and tricks with magnetic drill. I am interested in the gloves when working with steel beams. My prayers with you and your family. Allah give you healthy long life with full of peace and happiness. Aameen. Best wishes from Leicester ENGLAND.

[@markevans9130]

I use a Milwaukee cordless mag drill, it’s got a permanent magnet so no worries about power cuts, but still use the strap when upside down.

[@ukconstruction]

I am yet to try one mate are they good???

[@markevans9130]

@@ukconstruction excellent bit of kit. They have quick release collar for the cutters too. Saves faffing around with Allen keys. Not having trailing leads is a godsend on a busy site especially when you are up high in a basket

@@markevans9130 Nice one Mark, I will get one!!

[@aerobar2551]

Agree with that Mark, great tool, good solid magnet, easy to use and surprisingly light in weight. 👍

[@grumpyone5963]

When not using the machine coolant bottle, (if horizontal or countersink bit) I use a Oasis bottle with a 1mm hole in the lid and much cheaper soluble oil diluted with water. You can squirt a very fine flow on your bit as much as needed. I have a small cheap mag drill and a big boy Rotabroach Element 100.

[@lickopotamusslurperton1944]

I'm glad you mentioned that safety bit about drilling upside down at the end of the film. Nothing makes one more nervous than standing on a tiny stepladder with one of those beasts above you.

[@gordyl9247]

My steel supplier let me borrow a Mag. drill and I was doing exactly as you describe first time ever use, stepladder etc. Unbeknown to me my ever helpful wife was behind me, camera in hand, just as I switched the drill on she took a pic. The camera 📸 flash scared the life out of me, l couldn't believe that I wasn't electrocuted 😱🤣..... One one of our many laughs on our major renovation project...

[@johnmorrissey1675]

Great Drill for drilling beams 👍🇮🇪☘️🤟

[@marclindsay6120]

Been using my rotabroach for years . The magnet is so strong ,I use mine to drill 12mm holes to accommodate a 10 mm rod to suspend a plate for a sliding partition: the power is unreal. I took my guard off (bad practice) and I use wd40 as a lube for the cutter to cut through the beam . Beware though… take your time when drilling as I’ve had a few cutters shatter over time.

[@chrisohanlon69]

Great job, Robin

[@mpchmr1317]

30 years lol how time flies

[@Fearnstein]

Doing some ‘home improvements’ I need to drill some holes to the underside of a beam so I clamped a drill stand to the underside of a beam with an electric hand drill attached it did the job effortlessly, wasn’t worth buying a Mag drill

[@MelbourneAlan]

im suprised how littel lubricant you use robin. i use way more with mine. if i dont i find the cutters get very hot and dull quickly. i use a waterbased oil for metal bandsaws that recirculate the oil. its white . a few letres is 35 euro or so and a cap or 2 of oil will create a litre of coolant. works out way cheaper than those spray bottles. a mag drill is an amzing luxury to have. i couldnt live without mine and i dont use it that much but when i do it saves so much hardship

[@gordonclark7632]

If I heard correctly Robin you drilled a 14mm hole for a 12m bolt. If that for expansion or some other reason?

[@ukconstruction]

Its the perfect size enabling the bolt to fit without damaging threads etc

[@islandhopperstuart]

The technical term is clearance drill. Tables are available on the Web for the various metric thread sizes. 14mm is a bit sloppy for engineering fits, but I'm sure it gives Robin a little wiggle room in timber.

[@normanboyes4983]

If you drilled the holes 12mm - when it came to bolting up you would only get one bolt through - out of however holes you drilled.

[@mattcross5134]

Centre punching your pencil marks makes centring the cutter so much easier, you can literally do it with you eyes closed.

[@edwoodcarpentry]

Nice tip that!

[@grumpyone5963]

Came to say the same. Spring that centre pin right into it for pin point accuracy.👍

[@robertbamford8266]

Interesting tool. Manufacturer not available in US, but others are offered at prices $220 😒, $800, $1,000. Seems reasonable for a portable drill press. Even if it is manual feed. Thanks for the video.

[@ericmcrae7758]

I must be 2nd - You forgot your safety glasses on one of the holes - I would have edited that out. Love your channel.

How wide is it? Can they drill into the web of a beam?

[@firsteerr]

they used to be called broaching drills back when you had to plug things in !

[@davetaylor4741]

Glad to see it is a Rotabroach. They claim to be the original and was all I ever used in UK. British firm I believe. Not very common in Oz. Holemaker seems to be the brand here. Great tools and so useful. A basic but reasonable one here is $1000 so bit of a luxury unfortunately.

[@coolister3852]

you should not wear gloves when operating such drill, if the glove will get caught you may lose some fingers etc. just saying... love your videos mate HSE’s guidance states that gloves should not normally be worn by operators of pillar drills, undertaking this type of drilling work, due to the risk of becoming entangled with moving parts

[@MrGlenfraser]

Hi Robin, So can I fire a nail through a 47mm wall plate first plus a bed or mortar and then into the steel with one of them guns...???

[@christaylor5291]

Certainly not sir! Not the done thing.

[@michaelplays2449]

Great video !! thanks

[@spanishpeaches2930]

does the tin lid not cover that part filled with water ??

[@MojoHawks]

If the power cuts and stops the magnet 🧲 is there not a risk that the whole unit will start spinning? Or is there not enough torque left in the winding down drill bit?

[@youtubecensorseverythingIsay]

It'll spin and probably snap the broach off if the hole is deep enough, if not it'll just wind down

[@MojoHawks]

@@youtubecensorseverythingIsay so when it spins would that not be dangerous to the operator? Arm breaker etc? Or not powerful enough?

[@youtubecensorseverythingIsay]

@@MojoHawks they wind down pretty quick, I haven't heard of any broken limbs but if it's being used on its side or upside down it's necessary to use a safety strap or clamp it to the beam.

[@MojoHawks]

@@youtubecensorseverythingIsay yeah I just wondered about the torque once the magnet stopped. Didn’t know if it had a clutch or whatever, could catch you by surprise y’know. I’m not a driller so I’m speaking from a point of ignorance! Thanks 👍

….then we should (always) put our eye protection on before starting to drill…so sharp those bits of swarf….

I agree on using them for certain loads and for bolting steels to steels but if it’s just for a wall plate then a paslode spit gun or the older Hilti would be more than man enough. They are much more efficient you’d have your wall plates set and a few pairs of rafters cut and up into position by the time you’ve drilled those holes.

Gloves shouldnt be worn with rotating machinery, lathes, drills etc, due to the chance of entrapment. (Ok with off hand grinders due to the disc guard position).

[@PAGEREFURBISHMENT]

Not teaching you to suck eggs but I always centre punch before drilling keeps the spring loaded guide in place as they can wobble and jump off as the bit wears

[@billrimmer5596]

U marry all different types of materials. That one steel beam has more load bearing capacity than all the bricks and mortar in the whole house. U bolt a 2x6 to that beam. It’s like a piece of paper and a chunk of steel. It just seems like overkill, the size and strength of that I beam. Enjoy all the tools. I’m like a kid in the candy store. I absolutely look forward to every video. They must miss u at Skill Builder. RC is quite the draw

[@islandhopperstuart]

Bill its nothing to do with adding strength, just gives Robin something to shoot nails into for the next phase of timberwork built onto it.

[@stevendouglas3860]

1st Hi Robin

[@gourdarchibald6588]

I hesitate to offer advice to a master craftsman, but you are used to wood, I work with steel. NEVER ever wear gloves when you are producing long swarf - particularly cut proof gloves. The torque in that machine will absolutely be enough to pull the glove in and absolutely will NOT stop just because there is a hand inside - I don't care how strong the victim is - they will lose! I know this from experience and still have nightmares occasionally 30 years later - I had to help cut the poor sod free.

[@ukconstruction]

I appreciate your experience and that makes perfect sense, but if I filmed that without gloves then I would be criticised!! many thanks for your helpful and accurate comment mate

[@islandhopperstuart]

Robin, personally speaking, I would lift the tool out much more frequently to break the chips and to get more lubricant/coolant at the cutting edge.

[@Ivan-gm7zb]

The magnetic one I've used is X10 times slower than that 😂😂

[@badsmell4009]

Why not get the steel fabricator to put holes in 🙄

[@ukconstruction]

I mentioned in the video that we sometimes have the holes done before the steels arrive on site, however due to lead times etc and also final positioning etc we sometimes prefer to do this ourselves
