HOLEY GALAHAD is engineered to "open a window to your work" - no stopping to lift the grinder and check your progress. Holey Galahad increases productivity by up to 15% over Galahad. This is a great new addition. Discs can be used on both their face and edge surfaces. Made of durable Tungsten Carbide, there is no heat build up. Holey Galahad has 7/8" (22mm) centers to fit most 4-1/2" (115mm) and European 125mm angle grinders worldwide using King Arthur's Tools' Recessed Universal Nut.
Maximum 14,000 RPM. Discs are 4" (100mm) in diameter and feature patented structured tungsten carbide teeth bonded to steel discs over the total cutting surface. Tungsten carbide needles are manufactured in a 5-stage patented process. Made in the USA.
Patent Pending Discs provide you with an uncanny ability to see the surface being sanded through the disc as it spins.
