美国施泰力带柄开孔器采用等齿距（8齿/inch）能确保切割面光洁。独特的新型齿形双金属开孔器安全设计，能够兼顾等齿距开孔器精细切割及变齿距开孔锯快速切割,易排屑的优点 ，确保最大切割深度为41MM，达到开孔深度或钻透时手枪钻自动停止工作。美国施泰力（Starrett）双金属开孔器具有以下优势：
第一、双齿形设计，具有双重锯切功能，适用于更加广泛的材料上打孔，如木板和金属板材均可。
第二、排屑流畅，不塞齿，强的锯屑能力和抗震性使它钻孔时切割速度更快。
第三、Starrett双金属开孔器与普通变齿开孔器相比，使用寿命延长30%。
第四、施泰力双金属开孔器与普通等齿开孔器相比，不易卡锯或拉齿。
第五、切割深度达到41mm，相对开孔适度较深。
第六、规格齐全，孔径范围从14mm 至 210mm，基本满足各种需要。
