Drill bit Masonry, 1-½" x 14" for SP58

This drill bit is suitable for installing the SP58 asphalt anchors. The bit can drill to a depth of 10" through asphalt, gravel and earth. The shank is SDS MAX.  Note that due to sourcing issues, some of the drill bits we ship are longer than 10".  That does not affect their suitability for SP58 installation.  The bit has carbide tips for long life.  Carbide is preferred over diamond tips as the hole they dril in asphalt is rougher, promoting improved adhesion between the asphalt and the adhesive grout.  The hole still needs to be carefully cleaned from dust using compressed air.

While bit life varies with the surface of the asphalt and the gravel under it, we had reports of drilling 100 holes with one bit.
