The brazed carbide tip has a unique diamond ground 4-face design for excellent centered starts with little walking and best hole quality. The special grind angle creates sharper tip edges for fast starts in tough materials and the double ground flute ensures fast and efficient removal of the drilling dust and prevents clogging.

What Customers Are Saying

The drill bit performs well for drilling through common household materials like concrete, brick, and softer tiles, making clean holes without damage. However, it may be less effective for tougher materials like porcelain tile, with the bit wearing down or breaking after a few uses. The carbide tip stays sharp even after repeated use, and most customers are satisfied with the overall performance of the tool.

Slow going on tile

Would Recommend

I used this to drill through shower tile to hang a curtain rod. The bit skipped around some when I first started to drill. With my drill set at the highest speed, it took about ten minutes to drill each hole. I stopped frequently to wet/cool the bit. Don’t know if another option would have worked better.
