This invention relates to a bone chip drill, which includes a bone chip storage part, an adapter shank part, and a drilling/cutting part. The bone chips storage portion has a first end and a second end said second end is in opposite to the first end. The adapter shank part is connected to the first end of the bone chip storage part. The drilling/cutting part is disposed at the second end of the bone chip storage part. The drilling/cutting part has a V-shaped cutting head and a positioning drilling needle, the V-shaped drilling/cutting head has a tip, and the positioning drilling needle is disposed at the tip of the V-shaped cutting head. As such, it is capable of crushing bone at the same time during the bone chip taking process to save the time for crushing the bone by using a grinder and mixing bone chips after the bone has been taken out, and to avoid the loss of bone weight due to bone crushing by using grinder.本發明係關於一種取骨鑽頭。該取骨鑽頭包括一骨屑儲存部、一轉接頭柄部及一鑽削部。該骨屑儲存部具有一第一端及一第二端,該第二端相對於該第一端。該轉接頭柄部連接該骨屑儲存部之第一端。該鑽削部設置於該骨屑儲存部之第二端,該鑽削部具有一V型切削頭及一定位鑽針,該V型切削頭具有一尖部,該定位鑽針設置於該V型切削頭之尖部。藉此,可於取骨過程同時碎骨,以節省取骨後需另行以研磨器碎骨及混合骨屑的時間,並可避免研磨器碎骨所造成之骨量耗損。10‧‧‧取骨鑽頭11‧‧‧骨屑儲存部11a‧‧‧第一端11b‧‧‧第二端111‧‧‧貫通孔112‧‧‧止擋緣12‧‧‧轉接頭柄部13‧‧‧鑽削部131‧‧‧V型切削頭132‧‧‧定位鑽針1321‧‧‧刀刃結構133‧‧‧第一切削臂133a‧‧‧骨屑導引面1331‧‧‧側邊134‧‧‧第二切削臂1341‧‧‧側邊135‧‧‧尖部θW‧‧‧寬度方向夾角
