    5.0 out of 5 stars Through an i-beam like butta, April 6, 2017

    Needed to drill four holes through an i-beam to mount a pull-up bar. Regular cobalt drill bits barely made a dent. After reading the reviews, I decided to try this TEMO M35. Ok - not really like a hot knife through butter. More like ten minutes of sweaty torture on top of a ladder. But it got through over 1/2" of steel and didn't show any signs of slowing down on the fourth and final hole. I, of course, slowed down a lot.

    Use lots of oil and slow drill speed to keep the bit cool. I was drilling up into the i-beam, so I used a qtip to dab oil into the hole about every 15 seconds. The bit never got hot, although some of the shavings certainly did. Highly recommended.

  2. 2.0 out of 5 stars Waste of Time and Money..., June 3, 2017

    While the part number online matched the packaging, the product was not as pictured or described. Instead of having a 1/4" hex shank with a milled collar for use as a 1/4" hex bit, it was a round shank ground flat on 3 sides. I wasted $17 on an adapter due to this product not being what it was supposed to be. I'm giving it 2 stars only because the product quality appeared to be good, even though this transaction was an overall waste of time. It is very frustrating to plan out work and then end up further on hold due to the wrong parts and tools. Additionally, I had to pay UPS for packaging to return it. I wish I had taken a picture for you guys before I sent it back. I don't think I will risk buying a TEMO product ever again. I don't typically write reviews, but these guys earned it...

    5.0 out of 5 stars Superior Quality, April 6, 2017

    This is a superior quality bit.
    I use a cordless drill and cut through the steel frames that black oxide bites just scratch.
    Worth having in your drill bag.
