Great Bit - Even on Oak

Would Recommend

Worked well for holes on 3/4 inch oak. Pretty dull afterwards, but cut cleanly without chipping. Great non-carbide bit for a decent price.

Worked as described

Would Recommend

Used for drilling holes in 1x2x10s for Halloween gate. Chewed through the wood like a champ. Would recommend for small projects as didn't go any deeper than a 1x2

Good bit so far

Would Recommend

It’s really hard to give viable review after only one use but that being said, this bit cuts very clean with no chipping I used it in pine and was very please with it for the price.

Needs improvement

Would Recommend

It would be nice if this bit had a stepped shank instead of one size. It would also be nice if the center point was just a bit longer, maybe 1/3rd longer. The price was fair and the bit is pretty solid. It could just use a couple tweaks to make it 5*.

Works perfect

Would Recommend

The real test will come in November when I have 2000+ to drill. However, it’s working perfectly for its current job at hand.
