There’s no heat buildup. This flat extreme purple Holey Galahad is 120 grit on the TC scale. It fits most 4-1/2" to 5” standard (imperial) and 115mm – 125mm metric worldwide angle grinders. 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. Proudly Made in the USA.
For any flat Holey Galahad you do not need our recommended Universal Nut. Here’s why! The flat Holey Galahad body is slightly thicker than the round model and, in most cases, when seated over the arbor, will be level with, or rise slightly over the arbor. In this case using the angle grinder manufacturer’s locknut will tighten and secure Holey Galahad.
Read on: Universal Nut As An Accessory, Especially Any Round Holey Galahad. We highly recommend using our specially designed Universal Nut # 13750 (standard angle grinder) or #14000 (metric grinder), especially for any round Holey Galahad to secure the accessory. Here’s the difference between the flat and round discs.
The flat Holey Galahad body is slightly thicker than the round model and, in most cases, when seated over the arbor, will be level with, or rise slightly over the arbor. In this case using the angle grinder manufacturer’s locknut will tighten and secure Holey Galahad.
Every round profile Holey Galahad has a different inner wall design and slightly thinner metal thickness than flat Holey Galahads. The engineering and manufacturing design incorporating the 6 holes conflicted with the compatibility in using most manufacturers grinder locknuts to tighten the round disc. The disc was generally seated below the arbor, which did not allow over-width grinder lock nuts to secure the round Holey Galahads, causing the discs to spin freely. Our recessed Universal Nut overcomes this problem.Using this specially designed nut, you simply seat any style Holey Galahad, but especially the round profile, over the arbor and tighten. The depression in the universal nut seats over the arbor and securely tightens the disc. It also seats snugly in the deep well center of any Holey Galahad.
If using both round and flat Holey Galahads, get the respective size Universal Nut that suits your grinder. It will make securing all your accessories a breeze.
