Yup diamond bit should be your last options. Yeah, start slow, increase the speed until the bit getting 'better bites'. Remember push harder.

BTW, if possible try to mark the drill point with CENTER PUNCH. It help the bit to stay at one place, and at the same time breaking the smooth hard surface, which make drilling easier...


Please do report back here about your progress

Thank you.

Wow, din knw got 'rotary' drill, time to retire my old drill. Using it on concrete was a piss, the oil in the drill splatted out ..

i just use normal drill with impact button..
so if want to drill wall..i use the impact button..

Added on October 17, 2011, 5:13 pmu can also use smaller diameter carbide tip drill bit at first..
then change to bigger size ...i always use way..although maybe need to change 1-2 x
it makes drilling a lot more easier..

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.

how much is the flat chisel and bull point cost you ?
so the total you paid is ?

i was thinking of bosch gbh2-26

as it comes with

Part no. 0 611 254 76A
Carrying case (2 605 438 098)
Auxiliary handle (2 602 025 141)
Depth stop 210 mm (1 613 001 010)
SDS-plus quick-change chuck (2 608 572 213)
Keyless chuck 13 mm (2 608 572 212)
Set of concrete drill bits (6.5, 8, 10 mm)
Pointed chisel (SP no. 2 608 690 095)

Bosch GBH2-26.. An awesome rotary hammer., good chooice. Hope you can give a review about it later.


Since I am not using flat chisel and bull point much, I bought the 'cap ayam'/no brand
1) Flat chisel (small) : MYR9
2) Bullpoint : MUR15
3) SDS+ keyless chuck (bought from China), at MYR 25, Actually the cost only MYR11
4) Another 6mm drill bit. A Carbide tipped drill bit (Bosch X5L). MYR 29

Others,
1) Small combination L Squre with spirit level. Nice to have, if you want a 'perfectly' leveled fixings. No more guessing. Bought at ACE Hardware Mines.
http://www.amazon.co.uk/Rolson-6-Mini-Comb...e/dp/B005DKJUKI

2) Center punch, for marking and make a small 'pre-hole' before drillng.

3) Leather gloves. Just nice to have a pair. Not that expensive, MYR5 and above.

4) Small towel. Keeep tools cleaned.

5) A can of grease : Put small amoun of grease at the drill bit's groove and shaft for better
performance and longer lasting.

6) Lubricant oil.. Petronas Synthium 1000. the left over. All the drill bits are cleaned and lubricated with the oil before storage.

7) Dust mask. Very useful if you have asthma .

8) Safety glasses.Try to drill ceiling/overhead without them.

9) Concrete block for PRACTICING, as you seen in the youtube clip. Since I don't drill everyday, the concrete block is good for 'lepas gian' .. Seriously, since I got the HR2810, my interest in DIY is increasing tremendously.. Oya, I got the block lying beside a street at Balakong, near a construction site.

I want to mention another power tool which is the companion for my rotary hammer.


Makita TD0101F, corded impact driver with Vanadium Chrome #2 Philips bit. The hook is made using cloth hangging wire. This tool really make screw driving very handy and quck. The picture was taken just after fixing a curtain rail in my house.


Most of the DIYers have 'work bench' but, this is my 'work ladder', a 7 feet ladder

My wishlis
1) 16 and 24 mm Zentro, 4 cutters SDS+ drill bits. I don't know why I want that big sized drill bits, but who know, it might come handy in future.
2) Goatskin gloves...I found a pair at ACE Hardware@Mines,

Hope others also can share their experiences too.
Thank you.

L sq with spirit hmm you mentioned leeded fixing meaning ??

curious how does it help with leeded fixing..

hmm my wishlist is diamond tip dry coring bits lol

did you try your bullpoint on your concrete block and see how fast you can break it ? lol

This post has been edited by JinXXX: Oct 18 2011, 04:55 PM

Sorry for the typos... it should read as 'LEVELED'

Addition to my wishlist:
1) Digital Laser Range meter... Example : Bosch DLE 50 or DLE 70 or Makita LP060. The price..., wow....
2)... Reserved

@bahathir not sure how can the L level, help if you have something to drill which the holes are apart big painting.. thinking chinese horse picture the long big one..

how will that help.. a laser leveler would be more appropriate lol

But, if you are installing curtain rails or hanging pciture frames with 2 or more anchors, then a leveler is very handy to make them leveled.

Yeah, the laser leveler or ranger finder are nice to have tools, but, the PRICE keep me some distance away. It just too costly for DIYer like me.

i've seen some china laser leveler that cost less than 100 bux.. around...

seems like

cthardware is having promo for

bosch gbh 2-26 dfr

http://cthardware.com/gbh-2-26-dfr-professional.html

seems quite worth while

I did few experiments drilling through 2 types of tile using hammer drill and rotary hammer.

1) Porcelain (hard) tile
I tried to drill through a tile which being used as porch flooring. Yes, this tile is VERY HARD!. . I am not successfully to drill through using grease or lubricant oil. I only managed to drill a shallow hole. I also managed break the tile in seconds when using rotary hammer's rotary+hammer mode. So, rotary only mode is the only way to drill tiles. But, Just I found a technique.

Ooo.. using water soaked sponge for cooling,.. neat..
Key point is to keep drill bit cool. l. If I have time, I'll try the technique this weekend, hopefully. Drill guide plate, mmm... I can use hole from the soft tile, which I made earlier.
Bottom line: Diamond drill bit is your friend.


2) Normal (soft) tiles.
It is EASY to drill through normal tiles which being used in bathroom. I used 6mm Bosch Multi purpose drill bit for hammer drill, and Bosch X5L 6mm SDS+ and Makita 12mm SDS+ drill bits, which all these drill bits are carbide tipped.
In my tests, I able use hammer drill's hammer mode without damaging the tile. The key point is, start slow and increase the speed until it gets better 'bite'. In excellent condition, I able to drill through in 4 seconds.

Last night, I drilled 4 holes at my bathroom's tiled wall, to install a soap dispenser, using only rotary hammer and normal concrete/masonry 6mm drill bit.The combination made clean holes without any damage/crack to tiles.


Thank you.

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!

Hammering mode may crack the tiles, I try that before.

i use a free impact drill to drill simple hole on the wall.. It's free coz I got it free when I bought a Petronas Fully Synthetic Oil long time ago.. I guess, the value also must be around rm100++, but it does its job!

Congratulation for your Makita HR2470 (yup,HR2470 .

Yes, the HR2470 does feel solid and and the weight is also not that heavy (2.6kg), and nice to hold too. My advice is, starts slowly.. (1/2 power) before pushing it to full power. In my tests/experiments, I able to drill a hole in concrete even at about 1/4 of the power from my HR2810, but it took about 45 seconds to finished the task. At 1/2 of the power, I got 7 seconds, and with full power, 3 seconds....


Yeah, as weikee said, if you are using rotary hammer to drill through tiles, don't use rotary+hammer mode, because of the higher risk of breaking the tiles.


BTW, in this topic, I regularly use the term 'tests' or 'experiments' because, home fixing DIY is just my hobby, and I like to use the tools as efficient as possible. Using tool correctly will make the tool performs better and longer lasting. Also, it may prevent from injury or unwanted accident. That's why, I am training drilling into a concrete block, to gain experiences and 'feel' how the tool performs or limits, in real life.

Thank you.

Added on October 20, 2011, 5:45 pmYup impact hammer drill also did its job too for typical usage:)... But the limitations did drive me away from it, and that's why I got the rotary hammer.

I am thinking of SKIL 1715, 550w, and cheap. Wonder if that will be a better tool to replace my old hammer drill.

how much did it cost you ? u got it from the shop that ts recommended/bought his's from ?

i like the design of it very "modern"

SKIL 1715 : 2 kg class, 20 mm rotary hammer.

Actually, I was going to buy this model, after first experience using my brother in-law's rotary hammer. The attractive price, which is less than MYR300, and I did really want to buy it immediately at Home Depot. It is light weight (2.2 kg) and IMHO very suitable for light duty DIY tasks, such as drill wall for fixing or anchoring. The hammer only/chisel is a big plus. Most of rotary hammers are designed to last... If you try to use most of rotary hammer, you can feel how robustness and solid it being built. Remember this kind of tool need to destroy/demolish concrete wall/floor into pieces without being destroyed.

After researching in Internet, and based on reviews/articles, I chose Makita brand because of quality and excellent price/performance value. I picked Makita HR2810 because of the L shaped design looks attractive.

Ref:
http://www.skil.com.sg/skil/l0/product/pro...d=20&pid=&id=52

@bahathir

want to check with you, do you know how to quantify the feel of the impact energy rating ?

----

price i stated is the lowest i could find/see

SKIL 1715 , 550 watt, Impact 1.5 J , MYR ????
Makita HR2470 , 780watt, Impact 2.7J , MYR 500
Makita HR2810 , 800watt, Impact 2.7J, MYR ???
Bosch GBH2-26 DFR , 800watt, Impact 3.0J , MYR 750

seems like 2470 gives the best bang for the bucks spent vs performance
