Problem today drilling holes through a rafter / joist combination for coach
bolts - needed to drill 36 holes and couldn't get the ordinary drill into
the joist space at the right angle - ok go buy a cheap angle drill - look at
Screwfix - only expensive battery ones that probably aren't powerful enough
anyway. Got one of those nasty 90 deg gear boxes but they spin all over the
place and run horribly hot.
Improvised Solution: Standard Bosh angle grinder has a 14mm male stud - ex
old drill chuck has a 3/8" UNF male stud. Made an adaptor out of 35mm of
3/4" hex steel bar with a 14mm female thread at one and and a 3/8 UNF female
thread at the other - screw it all together and we have a (rather fast)
angle drill at zero cost. Drills 10 mm holes nice and square to the joists -
problem solved! OK it runs far too fast really but got the job done, and to
think I've struggled all these years under floors drilling slightly angled
holes for cable runs that you can never pull through in long lengths due the
the angles and I had a disguised angle drill in the tool box all the time!
aaargh just ordered the Ryobi "twin pack" from toolstation
on the other hand, the time I'd spend messing about making an adaptor and
hunting around for my old power controller, it's probably worth the £109....
Bosch angle grinder in toool box for last 7 years - no idea of price
Threading of hex bar simple job on lathe - took 10 minutes as I have the
Speed controller - haven't a clue as I didn't use one.
So if I go to a local machine shop, they will charge me £20 to do it, then I
have to buy then Bosch angle grinder, then the mains speed controller. And
it is not guaranteed to work either. The chuck could spin off causing
injury. All ads up. A search on Goggle gives £112 for a mains angle
drill. Rip off I know. The Royobi twin drill pack with an angle drill,
then looks excellent value for money.
Put a blunt drill in and at that speed you'd probably burn through
the joist. But for someone like Ferm ISTM that they would only have
to change the gear ratio and add a chuck to be able to offer a £25
angle drill, though when we discussed this a while back the feeling
seemed to be that the market just wouldn't be big enough.

You have to satisfy CE safety etc, which I'm sure a cheap conversion kit
All the big players make battery angles drills: DeWalt, Bosch, Makita.
Ryobi have now come on board and there are a few brands only available in
the USA too. And you may find soon that others will follow. A cheap main
drill can be thrown together for under £20.

I sent an email earlier today to NuTool, putting forward a suggestion
that they might like to think about bringing out an angle drill, and
also a laminate trimmer. I enclosed links to the tools I was
suggesting to ensure they fully understood what I was referring to. No
response as yet and perhaps there never will be.
However both of these devices are well within NuTool capabilities to
mass produce, and they could mop up if they brought out tools at a
If enough people put forward the same suggestions I'm sure the
relevant notice might be taken.
My published email address probably won't work. If
you need to contact me please submit your comments

I apologise for the additional effort, however the
level of unsolicited email I receive makes it
impossible to advertise my real email address!
NuTool do not make them. Jinding make them and put NuTools name on them.
The tools are from a standard catalogue. If Jinding make an angle drill
then Ferm or NuTool, etc could have one. Jinding made 14 million power
tools in 2003. Their catalogue is downloadable from the web site. You may
recognise some of the tool types which may be called NuTool, Challenge, etc.
The only 90 deg drill adaptor I've seen was £50+. You're right, it's a
massive gap in the market. I used one once with a small flap wheel which was
much more convenient than your standard drill.
Personally, I wouldn't fancy a flat bit on an angle grinder.
Well it's the usual story - it's not the actual job that takes the times
it's the setting up and clearing up afterwards. Actually doing the job -
probably 4 per hour - say £7.50 plus postage if enough people respond. Note
this is ONLY to make the adaptor - 14mm female to 3/8" UNF female - you need
your own chuck with a 3/8" unf male stud, and an angle grinder with a 14mm
stud (they mostly are) and the use you put it to is ENTIRELY at your own
If 10 people want them I'll make em
