電鉆

只具備旋(xuan)轉(zhuan)方式(shi)，特(te)別適(shi)合于在需要很小力的材料上鉆孔，例(li)如軟木、金屬、磚、瓷磚等。只是(shi)單(dan)單(dan)的憑靠電機(ji)帶動傳動齒輪加大鉆頭(tou)轉(zhuan)動的力氣，使(shi)鉆頭(tou)在金屬、木材等物質上做刮(gua)削形式(shi)洞穿。

沖擊鉆

依(yi)靠(kao)旋轉和沖(chong)(chong)(chong)擊(ji)來工(gong)作。沖(chong)(chong)(chong)擊(ji)鉆可用(yong)于天(tian)然的石頭或混凝土(tu)。它(ta)們是通用(yong)的，因為它(ta)們既可以用(yong)“單鉆”模(mo)式，也可以用(yong)“沖(chong)(chong)(chong)擊(ji)鉆”模(mo)式，所以對專業人員和自己動手(shou)者，它(ta)都是值得(de)選擇的基本電動工(gong)具(ju)。

電錘

依靠旋轉(zhuan)和捶打(da)(da)來(lai)工作，單(dan)個捶打(da)(da)力非(fei)常高(gao)，并具有每分鐘(zhong)1000到3000的捶打(da)(da)頻率，可產生顯著的力。與沖擊鉆相比(bi)，電(dian)錘需要最小的壓力來(lai)鉆入硬(ying)材料，例如石頭和混凝土，特別(bie)是(shi)相對較硬(ying)的混凝土。

Maigoo小貼士：三(san)者最根本的區別在(zai)于用(yong)(yong)途方面，電(dian)(dian)鉆(zhan)(zhan)(zhan)只能鉆(zhan)(zhan)(zhan)；沖(chong)擊鉆(zhan)(zhan)(zhan)能鉆(zhan)(zhan)(zhan)也能有稍微(wei)錘(chui)(chui)擊的效(xiao)果；電(dian)(dian)錘(chui)(chui)能鉆(zhan)(zhan)(zhan)和較高的錘(chui)(chui)擊。在(zai)日常使(shi)用(yong)(yong)時，木材和金屬鉆(zhan)(zhan)(zhan)孔(kong)可選(xuan)用(yong)(yong)沖(chong)擊鉆(zhan)(zhan)(zhan)，木板或鐵板打孔(kong)可選(xuan)用(yong)(yong)手電(dian)(dian)鉆(zhan)(zhan)(zhan)，混凝土墻上(shang)鉆(zhan)(zhan)(zhan)孔(kong)可選(xuan)用(yong)(yong)電(dian)(dian)錘(chui)(chui)。
