I am a home remodeler and have had to install T-bars on new cabinets. After years of hand marking all the holes or making custom fixtures out of reclaimed wood, I finally decided to try an adjustable fixture. Most of these attachments are designed to use 5mm bits, so I ordered this bit to use with them. I don't need a lot of metric fittings, so being able to buy a cheap, quality fitting was perfect for me. Drill bits, mostly maple and a few MDF. The drill was straight, with a sharp point, making it easy to accurately mark the location of the hole with a jig. The holes were clean and round with no cracks while the carrier was in use. The bat I received was NOT made in Austria as stated in the listing title and is not stamped with the Fisch logo. Fish brand packaging is made in China according to its design and specifications. Listing needs correction but at the time of my purchase this beat was under $3 with next day Prime shipping. I expected the same. It worked well and the bit that came with my mount was a joke so I'm a happy buyer.
