For what the tool is designed to do - it does very well. The cutter head holds it edge and cleans up nicely. I've made about 100 holes with the bit I use now and haven't had to sharpen it. Does a nice job.0 of 0 people found the following review helpful.Definitely was worth itBy Glenn S. SemeraroI bought this bit just to make the concrete slab weaker before hammering it and to break in my makita rotary hammer. I drilled about 50 holes so far in 4-5 inch concrete. Did the job with no problem and does not look worn at all. For the price it was a great investment for me.0 of 0 people found the following review helpful.Drills so fast you better not blinkBy Careful ResearcherExcellent bit, was drilling to set foundation bolts in relatively new concrete the first day and the bit just sunk in like drilling in dirt - actually went a little too deep it was so fast. Nice bit, good length.See all 3 customer reviews...
