　　電動(dong)工具(ju)選購技巧

　　1、如果您經(jing)常在混凝土墻(qiang)上鉆(zhan)(zhan)(zhan)孔，那(nei)么(me)一(yi)臺兩公斤電(dian)錘是您的(de)(de)(de)選擇。由(you)于(yu)電(dian)錘的(de)(de)(de)氣缸結構(gou)，捶(chui)打(da)力非(fei)常高，并具(ju)有每分(fen)鐘1，000到(dao)3，000的(de)(de)(de)捶(chui)打(da)頻率，可產生顯(xian)著的(de)(de)(de)力，使您在混凝土墻(qiang)上鉆(zhan)(zhan)(zhan)孔輕(qing)而易舉。配上一(yi)個轉接(jie)桿和普通電(dian)鉆(zhan)(zhan)(zhan)的(de)(de)(de)卡(ka)頭(tou)，它還能(neng)完(wan)成手電(dian)鉆(zhan)(zhan)(zhan)功能(neng)，達(da)到(dao)一(yi)機多用的(de)(de)(de)目的(de)(de)(de)。就是調速電(dian)錘+轉接(jie)桿+13毫米電(dian)鉆(zhan)(zhan)(zhan)卡(ka)頭(tou)，只(zhi)需幾(ji)百元，再配上幾(ji)支常用的(de)(de)(de)鉆(zhan)(zhan)(zhan)頭(tou)，那(nei)么(me)您家里的(de)(de)(de)大部分(fen)裝修(xiu)任務就可以自己(ji)完(wan)成了(le)。

　　2、如果除了混凝土(tu)鉆(zhan)孔，還(huan)要兼(jian)顧(gu)在木材和金屬上(shang)鉆(zhan)孔，并且在混凝土(tu)上(shang)鉆(zhan)孔在十毫米(mi)以下，就可(ke)以考慮(lv)沖(chong)擊鉆(zhan)，沖(chong)擊鉆(zhan)靠斜齒輪產生沖(chong)擊，沖(chong)擊力不如電錘。

　　3、如(ru)果(guo)您經常上(shang)緊(jin)或松開螺釘(ding)，或者在木板(ban)或鐵板(ban)上(shang)打孔，那(nei)么您可以購買一(yi)把充電(dian)(dian)式的(de)(de)電(dian)(dian)動起(qi)子，它在這兩個方(fang)面是(shi)方(fang)便(bian)的(de)(de)工具。充電(dian)(dian)式電(dian)(dian)動起(qi)子再加上(shang)一(yi)套起(qi)子頭(tou)套裝(zhuang)，輕(qing)松搞定您手頭(tou)的(de)(de)工作。

　　4、手電鉆大家肯定(ding)都知(zhi)道，它適合在(zai)木板或者鐵板上(shang)打孔(kong)，但是千萬不要指望它在(zai)混(hun)凝土墻上(shang)鉆孔(kong)有多(duo)大作為(wei),那樣做(zuo)很容(rong)易損壞機器，一只(zhi)手電鉆是經濟的電動工具，即使是進(jin)口的，也(ye)只(zhi)需要幾百元。

　　5、曲線(xian)鋸，如果您的動(dong)手能力(li)很強(qiang)，可以(yi)自己做一些(xie)家具或者(zhe)造(zao)型，那么曲線(xian)鋸您肯定需要，裝卡上(shang)合(he)適的鋸條，木板(ban)、鐵(tie)板(ban)、塑料(liao)板(ban)、不銹鋼等等很快就(jiu)能在您手下加(jia)工出您理想(xiang)的形狀.您可以(yi)選擇各種型號的曲線(xian)鋸，創造(zao)屬于您自己的造(zao)型。

　　電(dian)動工具(ju)選購技(ji)巧

　　1、如果您(nin)(nin)(nin)經常(chang)(chang)在混凝土(tu)墻上(shang)鉆(zhan)(zhan)孔(kong)，那(nei)么一臺兩公斤電(dian)(dian)錘是(shi)您(nin)(nin)(nin)的(de)(de)選擇。由于電(dian)(dian)錘的(de)(de)氣缸結構(gou)，捶打力非常(chang)(chang)高，并具有每(mei)分鐘(zhong)1，000到3，000的(de)(de)捶打頻(pin)率，可產生顯著的(de)(de)力，使您(nin)(nin)(nin)在混凝土(tu)墻上(shang)鉆(zhan)(zhan)孔(kong)輕而(er)易舉(ju)。配上(shang)一個轉接桿和普通電(dian)(dian)鉆(zhan)(zhan)的(de)(de)卡頭(tou)，它還能完(wan)(wan)成手電(dian)(dian)鉆(zhan)(zhan)功能，達到一機(ji)多(duo)用(yong)(yong)的(de)(de)目(mu)的(de)(de)。就是(shi)調速電(dian)(dian)錘+轉接桿+13毫米電(dian)(dian)鉆(zhan)(zhan)卡頭(tou)，只需幾百元，再配上(shang)幾支常(chang)(chang)用(yong)(yong)的(de)(de)鉆(zhan)(zhan)頭(tou)，那(nei)么您(nin)(nin)(nin)家里(li)的(de)(de)大部(bu)分裝(zhuang)修任務就可以自己完(wan)(wan)成了。

　　2、如果除(chu)了混凝(ning)土鉆孔，還要(yao)兼(jian)顧在木材(cai)和金屬(shu)上(shang)鉆孔，并且(qie)在混凝(ning)土上(shang)鉆孔在十毫米以下，就可以考慮(lv)沖(chong)擊鉆，沖(chong)擊鉆靠(kao)斜齒輪(lun)產(chan)生(sheng)沖(chong)擊，沖(chong)擊力不如電錘(chui)。

　　3、如果(guo)您經常上(shang)緊或(huo)松(song)開螺釘，或(huo)者在(zai)木板(ban)或(huo)鐵板(ban)上(shang)打孔(kong)，那么(me)您可以(yi)購買一把充(chong)(chong)電式的電動(dong)起(qi)子(zi)(zi)，它在(zai)這兩個(ge)方(fang)面是(shi)方(fang)便的工具。充(chong)(chong)電式電動(dong)起(qi)子(zi)(zi)再(zai)加上(shang)一套起(qi)子(zi)(zi)頭(tou)套裝，輕松(song)搞定您手頭(tou)的工作。

　　4、手電鉆(zhan)(zhan)大家(jia)肯定(ding)都知(zhi)道，它(ta)適合在木板或者鐵板上打(da)孔，但是千萬不要指望(wang)它(ta)在混凝土墻上鉆(zhan)(zhan)孔有多大作(zuo)為(wei),那樣(yang)做很(hen)容(rong)易損(sun)壞(huai)機(ji)器(qi)，一只手電鉆(zhan)(zhan)是經濟的電動工(gong)具，即使是進口(kou)的，也只需要幾百元(yuan)。

　　5、曲(qu)線鋸(ju)(ju)，如果(guo)您的(de)動手能(neng)(neng)力很強，可以自己做一些(xie)家具(ju)或者造型，那(nei)么曲(qu)線鋸(ju)(ju)您肯定(ding)需要，裝卡上合適(shi)的(de)鋸(ju)(ju)條，木板(ban)(ban)、鐵板(ban)(ban)、塑料板(ban)(ban)、不銹鋼等(deng)等(deng)很快就能(neng)(neng)在(zai)您手下(xia)加工出您理想的(de)形狀.您可以選擇(ze)各種型號的(de)曲(qu)線鋸(ju)(ju)，創造屬于您自己的(de)造型。
