I chucked up a Freud 5/8 Forstner bit in my press today (which I rarely use) and noticed the bit was spinning wonky. On inspection I found that the shaft had a serious gouge and that metal had been peeled away. A quick inspection of my other drill bits found similar gouges but not as severe.
So first off, dammit dammit dammit. Mucho dinero just went out the window.
But second, I can't seem to replicate these issues with my two hand drills and it has to be them because I haven't used most of these bits in my press. I'm pretty sure it's my Bosch 12v cause I use that one the most. I'm gutted right now cause I gotta replace the bits but I'd rather just replace the one culprit drill instead of two.
Any idea what causes this? Chuck slippage? I just don't know.MVIMG_20200713_152454.jpg
