This drill bit has made a significant difference in the speed and accuracy of my drilling tasks .Through trial and error, I found that this bit is versatile and can easily handle a variety of materials. The 135-degree angle ensures precise cuts without the need for excessive pressure. The durability is also outstanding lasting much longer than similar bits I have used in the past. The only downside is that the price is a bit higher than other options on the market. However, the quality and performance make it worth the investment..
