Tuff Stuff 45GMET 45 13300 Machinery

SKU CH-AWNR-Z9DBZ

4-1/2" depressed-centre wheel grinds metal at up to 13,300 RPM with double-reinforced industrial grit for extended life

  • Grinds various metals efficiently with a 4-1/2" depressed-center wheel
  • Double reinforced construction using industrial grit and glue extends service life
  • Superior friability continuously exposes fresh grain for sustained cutting sharpness
  • Suitable for both low-angle and vertical grinding applications
  • Maximum operating speed rated at 13,300 RPM for high-performance use

Tuff Stuff 45GMET Metal Grinding Wheel

This 4-1/2 inch depressed-centre wheel is built for metal grinding on angle grinders. It uses industrial grit bonded with reinforced glue to extend service life. The construction exposes fresh grain as it wears for consistent cutting action. Maximum speed is rated at 13,300 RPM for high-speed tools.

Suited For Metal Fabrication And Maintenance

Welders, fabricators and maintenance crews grinding steel, iron or similar metals will find the wheel matches low-angle and vertical grinding tasks. The double-reinforced design supports heavy material removal. It is not intended for cutting operations, stone, concrete or non-ferrous metals that require different bond types.

Capacity And Headroom For Grinding Work

The wheel handles standard metal stock removal, weld blending and edge preparation at full rated speed. Friable grain keeps the surface sharp through extended passes. Life decreases when used on unsuitable materials or above the 13,300 RPM limit. The 1/4 inch thickness provides material for multiple dressing cycles.

Questions about this item

Does my angle grinder need a 7/8" arbor to mount this wheel?

Yes, the wheel has a 7/8" arbor hole, so the grinder spindle must match that size for a secure fit.

Can I run this 13300 RPM wheel on a grinder rated for a lower maximum speed?

No, the grinder's maximum RPM must meet or exceed 13300; using it on a slower-rated tool is unsafe and can cause the wheel to fail.

How do I know the wheel is still cutting efficiently after extended use?

The superior friability continuously exposes fresh grain, so consistent material removal and a sharp feel indicate it is performing as designed.
