Overview
The Jet JT9-IBG8-21 Wheel Guard is a genuine JET replacement part for the IBG series industrial bench grinders. This is a bench grinder wheel guard designed to enclose the grinding wheel and control sparks and debris on JET IBG-8, IBG-8VS, IBG-10 and IBG-12 grinders, plus the IBGB-248, IBGB-248VS, IBGB-436 and IBGB-436VS belt and grinder combination machines. JET's previous part number for it is IBG8-21.
The guard is the housing around the wheel. On an industrial grinder that runs all shift, it takes abuse: dropped workpieces, a wheel that lets go, or the machine getting knocked off a stand. When it is bent, cracked, or no longer seats positively on the grinder body, JET's direction is to replace it. Running a grinder with a damaged guard is how a wheel failure turns into an injury.
Because this is the OEM part, the mounting points line up with the grinder body as they did from the factory. That matters on a guard: an aftermarket or improvised guard that sits a little off can rub the wheel or leave a gap where it should not.
This part replaces the wheel guard only. The matching outer wheel cover is a separate part, the Jet JT9-IBG8-25, and grinding wheels, tool rests and eye shields are also sold separately.
Buy this if you run a JET IBG or IBGB grinder in a fab shop, maintenance department, school shop or tool room and the guard is damaged, missing, or failing inspection. It is a fast way to get a quality industrial grinder back into safe service instead of tagging it out.

Pro Tip
Any time the guard or cover comes off, reset the tool rest to within 1/8" of the wheel and the upper spark guard to within 1/4" before you power up. Then spin the wheel by hand once to confirm nothing rubs before the motor ever sees it.

Tool Nut's Take
Don't Grind Without It
The Jet JT9-IBG8-21 is the factory wheel guard for JET's IBG and IBGB grinders, and it is the right fix when yours is damaged.
- Who it's for: Shops running JET IBG-8, IBG-10, IBG-12 or IBGB combo grinders that need a damaged or missing guard replaced.
- Why it stands out: Genuine JET fit across eight models, so one part number covers most of the IBG/IBGB lineup.
- Worth knowing: This is the guard only. If the outer cover is also damaged, add the JT9-IBG8-25.
