Frequently Asked Questions
What is the difference between Type-27 and Type-28 depressed centre wheels?
Type-27 wheels have a flat depressed centre profile and are used for general grinding at 15° to 30° angles. Type-28 wheels have a flared cup shape and are preferred for work requiring more aggressive flat surface grinding. Both are used on portable angle grinders.
What angle should I use a depressed centre wheel at?
Depressed centre wheels are designed to work at an angle of 15° to 30° with the work surface. They can also be used at right angles for specific grinding tasks.
What material are these grinding wheels reinforced with?
These wheels are reinforced with 2½ or 3 layers of fiberglass reinforcement for safe operation on portable angle grinding machines.
Can I use a depressed centre wheel on stainless steel?
Yes. The Stainless Steel and ZIRCOTECH variants are specifically formulated for stainless steel applications with iron-free composition to prevent contamination.
