Advice needed here please :-

I have to mount about 10 s/steel shelves
onto homogen tiled walls.

My old B&D impact hammer drill keeps burning
the tile bits, smoking when operating and takes
like 2-5 minutes to bore 1 hole. Too much of a
hassle...even my wrists ache after 3 holes!

Can any of you here offer me some solution
or advice? Many thanks.

Gosh your tip is appreciated.

Been using hammer mode plus hi-speed
so now I will use rotary mode, slower speed
plus oil or water to cool/lube the tile bit.

Will try this ltr today and hope it solves
my sore wrists and burnt bits! If cannot
then it's diamond bits for me.

Thanks!

To get the exact drill point I usually use 2" masking
tape over the area and mark the point with ballpoint
pen or marker. The tape also helps prevent the drill
from jumping and scratching the precicious surface.
Centerpunching may cause the tile to chip or form
an ugly crack if not done properly.

Got fed up with my ancient B&D impact drill
so I went out and bought myself a Makita
rotary hammer 2740 with 3 mode operation,
came with 5 bits plus regular chuck.

Felt real solid when operated and drilling into
hard tiles was easier and faster....saved me
lotsa time!

have done some work with settings on rotary,
rotary+hammer the past few days with the makita
2470...real powerful compared to the old faithful
impact drill.
wanted to do some he-man hammer mode work
today but was floored by the flu bug so I will have to
wait for another coupla days to experience the power
feedback! got some exterior wall drain clearance and
waterflow outlets to smoothen....

mAybee we should all get together, jinxxx, weikee &
me and inaugurate a 2470 makita handlers club...?

Could have a coupla TT sessions and HH, then go
mash up some boulders, rocks, monsoon drains
and cliff walls...WOW! WOW! WOW!

Ham it up mannnnnnnnn! Think of the possibilities.......

yo out there, I was at an electrical shop when I noticed
that there was a shop selling all sorts of power stuff
including mowers, pavers and makita stuff! Didnt have enuff
time to xplore cos of appt dat day but will do so nxt week...

Its in Paramount Gdn, PJ beside the Giant supermart which was
a cinema before. On a 1-way street with a large Makita signboard.

Just for your info....and expedition....
