A Core Interactive course on abrasive wheels and angle grinders delivering 11 interactions and 5 validated competencies across wheel inspection, wheel-to-job matching, and guard setup on real configurations. Workers learn to catch mounting and speed errors before pulling the trigger.
A tool-specific deep dive for workers who use angle grinders, cut-off tools and bench or pedestal grinders — metal trades, fabrication, construction, and maintenance. Aligned with the Manitoba WSH Act and WSH Regulation MR 217/2006 (tools and machinery), ANSI B7.1 (abrasive wheels), and OSHA 1926.303 / 1910.215.
Equip angle-grinder, cut-off-tool and bench/pedestal-grinder users to run abrasive wheels safely — select and match the wheel to the tool and the job (never over-speed a wheel), inspect and ring-test and mount wheels correctly, keep the guard on and stand out…

Who this course is for
Workers who mount, dress, or operate angle grinders and bench or cut-off wheels in fabrication, maintenance, and construction.
Metal trades, fabricators and welders who use angle grinders and cut-off tools
Construction and maintenance workers who grind, cut, or deburr with abrasive wheels
Anyone who uses a bench or pedestal grinder
Lead hands who choose and mount wheels for a crew
What you will learn
Select the right wheel for the material/job and match the wheel's maximum safe speed to the tool — never over-speed a wheel
Distinguish cutting wheels from grinding wheels and never side-grind a thin cut-off wheel
Inspect a wheel and ring-test a vitrified wheel before mounting, and store/handle wheels to prevent damage
Mount a wheel correctly — arbor size, matched flanges, blotters, not over-tightened — and keep the guard on and positioned
Explain wheel-burst physics, stand out of the plane of the wheel, and avoid pinch/kickback when cutting
Course outline
The Wheel Is Turning Faster Than You Think — Why an abrasive wheel carries hazards ordinary tools do not, what makes a wheel burst, and what this course covers.
Choosing the Wheel — RPM Match, Right Wheel, Cut vs Grind — Matching the wheel's maximum safe speed to the tool, choosing the right wheel for the material and job, and cutting wheels versus grinding…
Inspect, Ring-Test, Mount & Store — Inspecting a wheel for damage, the ring test for a vitrified wheel, correct mounting (arbor, flanges, blotters, not over-tightened), and…
Guards, Standing Out of the Plane & Kickback — Keeping the guard on and positioned, standing out of the plane of the wheel, letting a new wheel run up to speed, and avoiding pinch and…

Certificate and renewal
Passing the final test issues a QR-verified certificate, valid for one year.
This certificate records completion of knowledge training in the safe use of abrasive wheels and angle grinders. It does not authorize the holder to mount a wheel or set up a grinder on any particular tool. The wheel and tool manufacturers' instructions and the markings on the wheel always govern, and the employer must provide the hands-on setup training the work requires and confirm the worker is competent on the tools in use.
Common questions
