凿岩钻头是专为破碎和穿透坚硬岩层的钻孔作业而设计的专用工具。它们通常用于采矿、建筑、石油和天然气勘探以及采石等行业。这些钻头与钻杆和凿岩机配合使用，可有效地进行凿岩。其设计和材料特性确保其能够承受极端条件，在严苛的环境中提供可靠高效的性能。
岩石钻头的类型
我们提供各种类型的凿岩钻头，包括十字钻头和球齿钻头。其中，球齿钻头又包括螺纹球齿钻头、回缩球齿钻头和扩孔球齿钻头。
| 类型 | 简介 | 应用 | 直径 |
十字钻头 | 该设计通常采用多个十字形排列的十字刀片，以提高其在钻孔过程中破碎岩石的效率。 | 它主要用于钻穿裂缝岩石和磨蚀性地层，例如石灰岩、花岗岩和大理石。它尤其适用于高冲击力的凿岩机。 | 34毫米-65毫米 |
按钮钻头 | 这款钻头的钻头主体上巧妙地排列着硬质合金齿。这种设计可以实现多点破岩，从而提高效率并消除破岩作业中常见的盲区。此外，它还能防止岩石碎屑再次破碎。 | 钻机使用各种直径的螺纹球齿钻头来处理不同类型的硬脆岩层。 | 38毫米-150毫米 |
| 按钮钻头类型 | 简介 | 应用 | 直径 |
螺纹球齿钻头 | 凿岩钻头与螺纹钻杆连接，传递凿岩机的冲击力和旋转扭矩，以破碎岩石。 | 这款凿岩钻头适用于一般地质条件下的钻孔。其设计简洁，硬质合金齿块分布均匀，适用于各种硬度的岩石。 | 48毫米-152毫米 |
回缩按钮钻头 | 这种钻头采用独特的结构和制造工艺，可提高钻井效率。它通常采用空心设计，有助于排出钻井区域的岩屑，从而降低钻头卡钻的风险。 | 它主要用于松散、破碎的岩层，有助于回收凿岩工具，降低卡钻风险，并提高钻孔的直线度。常用于采矿和隧道开挖项目。 | 45毫米-152毫米 |
扩孔球齿钻头 | 该工具先钻一个特定深度的导向孔，然后再将孔扩孔至更大的直径。 | 它主要用于深孔钻削中的中心孔的铰孔。 | 64毫米-152毫米 |
更多参数
凿岩钻头分为R螺纹和T螺纹两种，型号包括R25、R28、R32、R38、T38、T45、T51等，可根据不同的工程需求选择不同的产品类型和型号。
