DIY - Adjustable Drill Bit [4K]

In this video, I make an adjustable drill bit. I start by using the metal I cut from the M12 bolt. Then I am cutting a Spade Drill Bit. Then I combine the two. This adjustable drill bit I made can be used to drill holes between 16mm and 35mm. It is possible to use it both by attaching it to the column drill and by attaching it to the hand drill. #AdjustableDrillBit #drillbit #drilling #wooddrillbit #designedbygreensaw ➤Tools/Supplies Used : Sanding Machine : https://youtu.be/lM-V20zzfjQ ➤Subscribe https://www.youtube.com/greensaw/?sub_confirmation=1 ➤My website : http://www.greensawdiy.com ➤Join : https://www.youtube.com/channel/UCFffS89D6ckU6ycxHulaNxg/join ➤Playlists: DIY Tools: https://www.youtube.com/watch?v=PLZFzQVHwj15gxNMWacspqqSMlWLRkiksX Clamps: https://www.youtube.com/watch?v=zNrEcNd5gCg&list=PLZFzQVHwj15j7wGkQX4EIEzRd7-nOeO8G Sanders : https://www.youtube.com/watch?v=tcDLvwU7ucQ&list=PLZFzQVHwj15iczFFydOxbcMt1TIWLeeMs Wood Turning : https://www.youtube.com/playlist?list=PLZFzQVHwj15iMT5jwkc_Sp3s1ZG-AyZkL Drilling Tools : https://www.youtube.com/playlist?list=PLZFzQVHwj15hehBh93G6gfrGH4GBZ6emP Wood Works : https://www.youtube.com/playlist?list=PLZFzQVHwj15jUi38AgPRs6VTjK96aa-9E Celaning : https://www.youtube.com/watch?v=ztP-uP29IeI&list=PLZFzQVHwj15icbL6VEqXyzrPR7DD5ImZm Band Saw : https://www.youtube.com/watch?v=rz7FJ5t9SOU&list=PLZFzQVHwj15gsCAgmzixToLgOxGggRivn
