I need to core-drill around 4x 100mm and 1x 180mm... Should I be better off buying a core-drilling machine (dunno what is called)?

QUOTE(weikee @ Aug 26 2013, 12:18 AM) Actually, 180mm is for kitchen ducting hole and the other 4x 100mm is for exhaust fan exit. Thinking of buying this drill and pay 2 workers to drill for me...The wetworks contractor is charging me RM 200 for 180mm and RM 500 for the other 4x 100mm holes... If I buy this drill and bits around RM 700 also... But I pay the workers la... N I keep the drill |

QUOTE(hianz86 @ Aug 26 2013, 04:16 PM) Actually, my normal hand drill is Bosch.I have 2x impact drills... 1 from Bosch 500w (dunno what model) and one China-branded 1200w - seriously, drilling power better than Bosch. Bosch is good... Now I am planning to get some China-branded diamond core drill and rotary hammer drill... All about money la... LoL! |

QUOTE(ERN2 @ Aug 27 2013, 02:59 PM) I do not know how to cramp the RJ45 head, so I bought the really made 15meters cat6 cable running from my ground flood to upper flood. Exactly! I just bought myself a new rotary hammer and diamond core drilling... Finger-crossed... All are now waiting to be shipped to me from China... So I have to drill 2 holes go through the concrete beam. I do not have other power tools like the rotary hammer or impact drill, neither my friend nor neighbor have it. What I have is a 350W drill which I bought it at carefour in 1998 (RM69 is very good price then at that time). The RJ45 for cat6 is very big, my drill support up to 13mm, but I bought a 16mm bit (can fit) to drill the hole, through the concrete beam. It took me 2 hours to drill 1 hole. I need to stop every 5 minutes to let the drill bit cool down. The dill bot loosen every now and then thus I need to r-tighten it. the 16mm hole can let 1 branded AMP cable go through (with RJ45 head), the 2nd one cannot go through leow. I have to buy a non-brand Cat6 cable from lowyat to snip through it. I also drilled 3 holes at the concrete floor to install the projector bracket, it tools me 45 minutes for 1 hole enough to put in the wall plug. The drill survived the ordeal and now I fit it at a portable drill press, I also use it to drill pocket holes. Such a good buy for me. Why I torture my drill at the first place? Well, my brother ask me to buy the 16mm bosch, so I was adoring and prepare to throw the 13mm away. For driving the screw, now I use a china brand cordless driver. The rotary hammer is my next buy if I need one. This post has been edited by sw.boutique: Aug 27 2013, 08:34 PM |

QUOTE(H2D @ Aug 27 2013, 08:37 PM) It is because the box here is *most of the times* either directly translated or brought in by the local entrepreneur. If for those good Chinese-branded one, I dont think they are cheap here. The brand I bought is called Dong Cheng (top 10 in China I guess from what I researched), 26mm and about 3J impact energy, around RM 130 for the rotary hammer and plus all the accessories, flat chisel, groove chisel, moil-point chisel, 150mm long drill bit sets (6, 8, 10, 12), 16x350mm and 2x extra carbon brushes... Altogether about RM 180, shipping another RM 75 (seafreight + local delivery, roughly)... Should match the price of entry level rotary hammer?But the price of diamond core drill here is killer, look at this link: http://www.lelong.com.my/diamond-core-dril...3-10-Sale-P.htm, about RM 750 for a 110mm version. I am now using the same price to buy one up to 159mm diameter, and with 7 diamond drill bits (excluding shipping, maybe another RM 50 since I combine shipping). |

QUOTE(weikee @ Aug 27 2013, 09:00 PM) My last use on such power tools from China was bad. Nearly kill myself. I never want to buy power tools from unknown China made. Just be careful when use. Spark can come electrocut. The head can snap and fly out and shoot someone. Nvm, not using by me, those professional workers should be able to point out for me... |

QUOTE(ERN2 @ Aug 28 2013, 01:36 PM) I am TaoBaoHolic too. For professional who need to use it every day, it is better to buy the branded one like Bosch, Makita. I am just a simple DIY use the tools once in the blue moon. My thinking is like this, a Bosch cutting tool say RM1000, can last for 100,000 cuttings. An alcheapo brand cutter with the same function cost around RM200, can last for 1000 cuttings only. I am doing 100 cutting every year, so the alcheapo can last for 10 years. At the end of 10 year, I can throw away the alcheapo tool and buy the latest alcheapo with newer technology at that time. I know many concern about the safety issue, that is why I also choose a better built alcheapo. I am also adoring/admiring the branded tools, like the Makita TD0101F, how much I love to have it, instead of the 27Nm alcheapo. Ha, I use the carefour bought drill for sanding too. Skil for Bosch, Maktec for Makita, Black & Decker for Dewalt, are made in china now. |

For that 180mm drill bit alone, about RM 180.
