today I'm going to be removing some tamper-proof screws so I've got some heavy-duty cut-off wheels and then here's some lighter duty cut-off wheels I'm gonna be using my heavy duty cut-off tools I have some like I said tamper proof screws it is not the screws so that I can actually turn them out anyway on the front of this deal here we've got a little Phillips a little common screw I'm not a Philips screw you can remove that screw and that will allow us to add our cutoff wheels to this head here so there's the cutoff wheel we'll take that little tiny screw pass it through and turn it on in and you don't want to over tighten these just snug is good and you may have to replace it often depending on what you're doing I'm going to be cutting into some metal screw heads and giving a flat bit that I can turn out to make them easier anyway this goes back in here just like like a drill bit and I'll push the button down again so it locks in place and then tighten it down and for tightening I can pretty much just hand tighten it release it now ready for action now I'm changing the blades of course you want to have this on plugging it in now testing it out my speed setting here a notch in these tamper proof screws so I'll be able to turn it out definitely want to make sure you were in safety glasses for this maybe some ear protection
