1. 钻头是一种旋转而头端有切削能力的工具,一般以碳钢SK,或高速钢SKH2, SKH3等材料经铣制或滚制再经淬火,回火热处理后磨制而成,用于金属或其它材料上之钻孔加工,它的使用范围极广,可运用于钻床、车床、铣床,手电钻等工具机上使用。2. 钻头种类A.依构造分类(1).整体式钻头：钻顶、钻身、钻柄由同一材料整体制造而成.(2).端焊式钻头，钻顶部位由碳化物焊接而成.B.依钻枘分类 (1).直柄钻头：钻头直径于ψ13.0mm以下，皆采用直柄. (2).锥柄钻头：钻头柄为锥度状，一般其锥度均采用莫氏锥度.C.依用途分类(1).中心钻头：一般用于钻孔前打中心点用，前端锥面有60°, 75°, 90°等,车床作业时为了用尾座支,持应该用60°中心钻与车床尾座顶心60°相配合.(2).麻花钻头: 为工业制造上使用最广泛的一种钻头,我们一般使用的就是麻花钻头.(3).超硬钻头: 钻身之前端或全部以超硬合金刀具材料制成,使用于加工材料之钻孔加工.(4).油孔钻头: 钻身有两道小孔,切削剂经此小孔到达切刃部份,以带走热量及切屑,使用此钻头一般工作物旋转,而钻头静止(5).深孔钻头:最早用于枪管及石包管之钻孔加工,又称为枪管钻头。深孔钻头为一直槽型,在一圆管中切除四分之一强的部份以产生刃口排屑(6). 钻头铰刀: 为了大量生产之需要,其前端为钻头,后端为铰刀,钻头直径与铰刀直径只差铰孔之裕留量,也有钻头于螺攻丝混合使用,故又称为混合钻头.(7). 锥度钻头: 当加工模具进料口时,可使用锥度钻头.(8). 圆柱孔钻头: 我们称其为沉头铣刀,此种钻头前端有一直径较小之部分称为道杆.(9).圆锥孔钻头: 为钻削圆锥孔之用,其前端角度有90°,60°等各种,我们使用的倒角刀就是圆锥孔钻头的一种.(10).三角钻头: 一种电钻所使用之钻头,其钻柄制成三角形之面,使夹头可确实固定钻头.钻头规格及长度钻头外径钻头长度钻头外径钻头长度φ20mm350mmφ102mm350mm/420mmφ22mm350mmφ108mm350mm/420mmφ24mm350mmφ110mm350mm/420mmφ26mm350mm/420mmφ114mm350mm/420mmφ28mm350mm/420mmφ120mm350mm/420mmφ30mm350mm/420mmφ127mm350mm/420mmφ32mm350mm/420mmφ132mm350mm/420mmφ38mm350mm/420mmφ150mm350mm/420mmφ40mm350mm/420mmφ159mm350mm/420mmφ44mm350mm/420mmφ166mm350mm/420mmφ50mm350mm/420mmφ180mm350mm/420mmφ57mm350mm/420mmφ200mm350mm/420mmφ63mm350mm/420mmφ220mm350mm/420mmφ76mm350mm/420mmφ250mm350mm/420mmφ83mm350mm/420mmφ275mm350mm/420mmφ89mm350mm/420mmφ300mm350mm/420mm钻头规格180度规格小径大径全长小径刃长柄径M33.46.565136.5M44.58.075188M55.59.585229.5M66.611.0902511M89.014.01002812M1011.017.51103012M1214.020.011532121/46.8511.09025115/168.5514.010028123/810.115.011030121/213.520.01153212钻头规格90 度 规格小径大径全长小径刃长柄径M33.46.465356.4M44.58.475428.4M55.510.4855010.4M66.612.5905312.0M89.016.51005312.0钻头规格180度规格小径大径全长小径刃长柄径M33.46.565136.5M44.58.075188M55.59.585229.5M66.611.0902511M89.014.01002812M1011.017.51103012M1214.020.011532121/46.8511.09025115/168.5514.010028123/810.115.011030121/213.520.01153212钻头规格90 度规格小径大径全长小径刃长柄径M33.46.465356.4M44.58.475428.4M55.510.4855010.4M66.612.5905312.0M89.016.51005312.0钻头外径钻头长度钻头外径钻头长度φ20mm350mmφ102mm350mm/420mmφ22mm350mmφ108mm350mm/420mmφ24mm350mmφ110mm350mm/420mmφ26mm350mm/420mmφ114mm350mm/420mmφ28mm350mm/420mmφ120mm350mm/420mmφ30mm350mm/420mmφ127mm350mm/420mmφ32mm350mm/420mmφ132mm350mm/420mmφ38mm350mm/420mmφ150mm350mm/420mmφ40mm350mm/420mmφ159mm350mm/420mmφ44mm350mm/420mmφ166mm350mm/420mmφ50mm350mm/420mmφ180mm350mm/420mmφ57mm350mm/420mmφ200mm350mm/420mmφ63mm350mm/420mmφ220mm350mm/420mmφ76mm350mm/420mmφ250mm350mm/420mmφ83mm350mm/420mmφ275mm350mm/420mmφ89mm350mm/420mmφ300mm350mm/420mm钻头规格180度规格小径大径全长小径刃长柄径M33.46.565136.5M44.58.075188M55.59.585229.5M66.611.0902511M89.014.01002812M1011.017.51103012M1214.020.011532121/46.8511.09025115/168.5514.010028123/810.115.011030121/213.520.01153212钻头规格90 度规格小径大径全长小径刃长柄径M33.46.465356.4M44.58.475428.4M55.510.4855010.4M66.612.5905312.0M89.016.51005312.0中心钻头规格表 刃径(d)刃径公差刃长(L2)柄径(D)全长(L)0.40.05-0.050.53.031 0.50.05-0.050.63.031 0.60.05-0.050.73.536 0.70.05-0.050.83.536 0.80.05-0.050.94.036 0.90.05-0.051.04.036 1.00.05-0.051.24.0361.24.01001.20.05-0.051.45.042 1.50.05-0.051.85.0421.85.01001.85.01501.85.02002.00.08-0.082.45.0422.46.01002.46.01502.46.02002.50.08-0.083.06.0473.08.01003.08.01503.08.02003.00.08-0.083.67.7573.610.01003.610.01503.610.02003.20.08-0.083.87.757 4.00.08-0.084.810.0694.810.01004.810.01504.810.02005.00.12-0.126.011.0696.012.01006.012.01506.012.02006.00.12-0.128.016.090 8.00.12-0.1210.018.0100 10.00.12-0.1212.018.0100 12.00.12-0.1215.022.0110
