Ceramic cartridge roll for aggressive grinding with maximum stock removal rate on hard materials which do not conduct heat well. Consistently high performance due to self-sharpening ceramic oxide grain. Active grinding additives in the coating substantially improve the stock removal rate, prevent clogging and result in cooler grinding.

• Premium Ceramic Grain – Fast cutting and long-lasting performance on stainless steel, carbon steel, and alloys.

• Straight/Untapered Design – Ideal for inside corners, fillets, tight spaces, and detailed finishing.

• Heat-Resistant Bond – Stays sharp under pressure and reduces heat buildup.

• Strong Cotton Backing – Prevents breakage during high-speed grinding.

• Universal Compatibility – Fits most mandrels and rotary tools.

Fermi Abrasives Ceramic Straight Cartridge Rolls are engineered for metalworkers who need high cutting efficiency and stable performance in demanding applications. Made from premium ceramic abrasive grain, these rolls deliver exceptional stock removal on stainless steel, carbon steel, cast iron, and high-nickel alloys.

The straight/untapered shape allows access into tight corners, fillets, narrow slots, and areas where traditional abrasives cannot reach. With a self-sharpening ceramic structure, the rolls maintain fast, cool cutting with reduced heat buildup and longer life.

They are widely used for weld blending, deburring, edge smoothing, surface preparation, and precision finishing in fabrication shops, stainless steel tank production, auto repair, aerospace parts, and industrial polishing tasks.

Applications：

• Weld blending & weld bead leveling

• Inside corner / fillet sanding

• Deburring machined or stamped parts

• Surface preparation

• Precision finishing in tight areas

• Stainless steel tank fabrication

• Automotive & aerospace finishing

FAQ

Q1: What tools can these rolls be used with?
A: They fit standard mandrels for die grinders, rotary tools, and pneumatic grinders.

Q2: Are ceramic rolls better than aluminum oxide?
A: Yes. Ceramic is self-sharpening, cuts faster, and lasts longer.

Q3: Suitable for stainless steel?
A: Absolutely. Ceramic grain performs extremely well on stainless steel.

Q4: Do you offer bulk or OEM service?
A: Yes, bulk orders, OEM, and private label are available.
