請參考圖7與圖8，由於該嵌卡槽165具有兩導槽凹部164與一導槽凸部166而概呈W形，增加該嵌卡槽165與該支撐導塊30的嵌卡端部33之間的承靠貼面的數量與方向，進行倒角切削時，該支撐導塊30所受到的軸向沖擊，可以利用W形的該嵌卡槽165加以分散，降低倒角切削軸向下壓該鑽床倒角刀具時，對該刀頭部13產生的軸向沖擊，避免該刀頭部13軸向震動，進而提高加工品質。Please refer to FIG. 7 and FIG. 8 , since the insertion slot 165 has two guide groove recesses 164 and a guide slot protrusion 166 and is generally W-shaped, the insertion slot 165 and the insertion end of the support guide block 30 are added. The number and direction of the bearing surfaces between 33 and 33, when chamfering is performed, the axial impact on the support and guide block 30 can be dispersed by the W-shaped inserting groove 165 to reduce the axial impact of chamfering cutting. When the chamfering tool of the drilling machine is pressed down, the axial impact on the tool head 13 can avoid the axial vibration of the tool head 13, thereby improving the processing quality.

較佳的是，該嵌卡槽165的各導槽凹部164為圓弧凹面，該嵌卡槽165的導槽凸部166為圓弧凸面，且該支撐導塊30的嵌卡端部33的各導塊凸部333為與其對應的導槽凹部164的形狀相匹配的圓弧凸面，該嵌卡端部33的導塊凹部334為與該嵌卡槽165的導槽凸部166的形狀相匹配的圓弧凹面，而可利用圓弧的凹面與凸面的配合方式達到分散應力的效果。Preferably, each guide groove concave portion 164 of the inserting slot 165 is a circular arc concave surface, the guide groove convex portion 166 of the inserting slot 165 is a circular arc convex surface, and the inserting end portion 33 of the supporting guide block 30 has a circular arc concave surface. Each guide block convex portion 333 is an arc convex surface matching the shape of the corresponding guide groove concave portion 164 , and the guide block concave portion 334 of the inserting end portion 33 is the shape of the guide groove convex portion 166 of the inserting groove 165 . The matching arc concave surface can be used to disperse the stress by using the matching method of the arc concave surface and the convex surface.
