Grinding accessories and jobs

• Type 27 depressed-center grinding wheels: weld cleanup and material removal, when approved for this tool and guard.
• 5-inch flap discs: blending welds, bevels, and surface preparation; select compatible abrasive, backing and arbor.
• Wire cup brushes: corrosion and coating removal only when expressly suitable for this grinder, guard and spindle system.
• Air supply accessories: suitable hose, fittings, regulator/filter and manufacturer-recommended lubricator.

Wheel safety: Use only manufacturer's approved wheel types, properly rated at or above the tool's marked speed, with correct flanges, arbor and original guard. Never use an unapproved cut-off wheel or remove the guard. Check the exact tool identification before accessory selection.

Read manufacturer operating manual.

Which Universal Tool grinder is right for the job?

Compare the tools by application and accessory type. All accessories are sold separately and must be approved for the actual tool and operating speed.

Accessories and application guide

Carbide burrs: Metal deburring, detail work, and weld edge cleanup. Select the right burr geometry, shank diameter and manufacturer-approved maximum RPM. M.A. Ford carbide tooling may be sourced upon request.

Mounted grinding stones: Small-area grinding and finishing where the specific stone size, shank and RPM rating suit a compatible die grinder.

Sanding and surface-conditioning: Choose an approved holder, spindle fitting and abrasive disc for the specific tool. The UT8724T-20 is a distinct model; do not interchange accessories with the UT8724-20 without checking the exact interface.

4-1/2-in and 5-in wheels: The UT8780-1 and UT8784-5 are larger angle grinders requiring the correct guards, flanges, compatible discs and operating-speed ratings. Do not assume cut-off operations are approved.

Precision turbine grinding: The UT8711-T requires accessories suitable for its high operating speed; do not install standard die-grinder stones or burrs without explicit manufacturer suitability.

Important: Use the original manufacturer manual to confirm permitted accessory type, maximum diameter, shank/spindle specifications, speed rating and PPE. Application descriptions are examples, not tool approval for specific aircraft maintenance or regulated procedures.
