Irwin Marples great value

I use these in drill press. Take my time and these work just fine. I use sacrifice board and these bites result in nice and smooth bores. Take care of these and they last for years. I highly recommend Irwin Marples products. Note: I am a novice woodworker with small garage shop.

Good clean bit for removing plugs

Would Recommend

Got this to remove 1/2" wood plugs in a all wood door. Plugs were covering screws. Bit is super sharp and precise. Worked well without harming wood outside of perimeter.
