油壓鑽 鑽咀 虛位大..

Very clumsy to use hammering drill to drill wood, different drill bits. Would need an adapter chuck. very long.
Some hammering drills are having chiselling function, very useful for large through wall hole,70mm for refrigerant pipes.

鑽木要平鑽 (即唔係用四坑頭) 用轉換器都唔會準.
所以冇乜人用油壓鑽鑽木, 除非你係用來當破柴咁鑽.

請問油壓鑽加轉換頭後適合鑽乜用｡Tks.

當平鑽用來鑽任何野, 當然唔可以開撞擊功能.
叫多個用途, 例如唔講究既工程, 要木門開個孔, 咪可以用佢囉.
但預左開出來唔平整.

鑽鐵閘、角鐵、金屬。

兩位師兄，tks.

其實你拎上手一開機就知, 唔用converter, 插知四坑都"發發"下...
如果你有長鑽頭, 上左去一開機, 劃個大圓圈添.

試過用手搖吓佢都郁郁吓咁.

呢碌嘢仲未用過, 遲些可能要用.

建議初學用衝擊鑽，學下手感，力度，控制鑚速同扭力等，
學鑽唔同物料分別，石屎，磚，不鏽鋼，鋁角，木材，除拉釘等

鑽返兩三年，有經驗到時轉用油壓
而且油鑽結構虛位比衝擊鑽大，新手難掌握

If you drill granite, you need a very powerful one. For home application, it's only for 3/8" or 5/16" max. Check dia. of the anchorage bolt for proper drill bit. For larger size(say for water pipe),you can drill small hole first and then change to larger drill bit. Slower but can still accomplish the work.

I am using this one(plus an old 220V Metabo drill, MIG, very robust) Quite handy and for village house internal partition(only sand brick), no problem at all. Concrete 5/16" usually.(for fixation and eye bolt for lifting, 3/8" for heavy loading such as split type at external wall but not recommended due to illegal structure)

Bare tool only, can have another drill set for the compatible battery. Can't ship lithium battery alone.

請教一下, 依家用衝擊鑽鑽主力牆, 根本鑽唔入, 想買一把紅M油壓鑽. 上網見有好多型號, 請問應該買甚麼型號較好? 謝謝

up下
家用, 1年 或 鑽 3幾個,
細細把600火都已經OK

;

好多大窿要鑽 或 深窿要鑽,
800火附近.

大火d, 好力d, 大把d, 重d & 貴d.

請問電錘係咪即係油壓鑽?

佢咁細把 470火 叫電錘

hammer drill= 電錘?
rotary hammer = 油壓鑽?
