请按照您手中的电钻/电锤槽口选用合适的柄型钻头

n

正常是重型电锤是用方柄四坑的钻头，家用小型冲击电钻用圆柄两槽两坑

n

本品为高档合金电锤钻头，采用优质的40cr钢材，以及原生料YG8C硬质合金为原材料加工而成，在优质的原材料基础上，经高温淬火，硬度大大提高，加上系例的表面处理，使得本产品从外观及使用，都比一般中碳钢钻头更加美观，使用寿命更长。

n

电锤钻头没有刀刃，只有个135度角的合金凿头，靠凿击物体钻洞，旋转是为了排出粉末、碎片，还有就是为了凿出圆形的洞。这个性质决定了电锤钻头只能对付硬度高，脆性大的物体，比如混凝土，砖墙，石头，花岗岩，瓷砖或大理石（建议用专用的钻头）等硬碎物品。

n

9mm和11mm钻头特别定做，价格稍高一些

n

有客户反应砖墙比较松，不锈钢膨胀螺丝M6、M8、M10的砖墙安装可以考虑用9号、11号和13号的钻头打孔，这样紧一些，方便紧固。
