STEELOX POLIFAN PFC Flap Disc

STEELOX POLIFAN PFC flap disc: performance and longevity on steel

The STEELOX POLIFAN PFC flap disc is designed for intensive work on steel. A high-performance abrasive, it combines material removal speed with an extended service life.

Its fiber flap design ensures consistent sanding and optimal temperature resistance, even during prolonged use.

Ideal for grinding, deburring, and finishing metal parts, it is a benchmark tool for demanding professionals.

What is the STEELOX POLIFAN PFC flap disc?

The STEELOX POLIFAN PFC flap disc is a rotary abrasive designed specifically for working on stainless steel and carbon steel. It combines aggressive cutting with a neat finish in a single pass.

It is manufactured by Pferd, a global leader in precision abrasives. The STEELOX range targets demanding applications where both disc longevity and surface quality are critical.

POLIFAN PFC technology: design and materials

The acronym PFC (Polifan Fiber Compact) refers to a construction with flaps arranged in a fan shape, overlapping at a constant angle on a compact fiber backing. This geometry ensures uniform contact throughout the entire life of the disc.

The flaps are made of zirconium corundum, a self-sharpening abrasive that renews itself as it wears down. The result: the cut remains constant from the first to the last millimeter of material.

The STEELOX formulation is free of iron, sulfur, and chlorine. It prevents any metallurgical contamination of the workpiece, a mandatory requirement for stainless steel and high-value-added steels.

• High-resistance compact fiber backing
• Flaps made of self-sharpening zirconium corundum
• Formulation free of iron, sulfur, and chlorine
• Compatible with standard angle grinders
• Maximum speed: 80 m/s

Applications and materials compatible with the STEELOX POLIFAN PFC

The STEELOX POLIFAN PFC is designed primarily for working on steel and ferrous metals. It is its specialty, and it excels in this field.

It covers common metallurgical and boilermaking operations: grinding, deburring, chamfering, and aggressive sanding. The result is clean, fast, and without excessive effort on the grinder.

Its abrasive flaps with zirconium or aluminum oxide grain self-sharpen during use. The abrasive remains constantly active, which extends the life of the disc.

The STEELOX POLIFAN PFC stands out for its PFC (Pressed Fiber Cone) design: the pressed conical body offers better stability and an optimized angle of attack on both flat surfaces and edges.

Technical characteristics of the STEELOX POLIFAN PFC flap disc

The STEELOX POLIFAN PFC flap disc is designed specifically for work on steel. Its flat shape design (type 27) ensures optimal contact on flat surfaces and welds.

The flaps are made of zirconium corundum, an abrasive particularly resistant to heat and crushing. This grain continuously renews itself during use, maintaining constant aggressiveness throughout the life of the disc.

Grain, dimensions, and maximum permissible speed

The STEELOX POLIFAN PFC is available in several grit sizes, adapted to each stage of work:

• Grit 40: aggressive roughing, fast material removal
• Grit 60: intermediate grinding, weld finishing
• Grit 80: standard finishing on steel
• Grit 120: pre-finishing, preparation before painting

The available diameters are typically 115 mm, 125 mm, and 180 mm, compatible with standard angle grinders. The central bore is 22.23 mm.

The maximum permissible speed is 80 m/s (i.e., 13,300 rpm for a 115 mm disc), compliant with the EN 13743 standard. This value is printed on the disc and must never be exceeded.

Product	Abrasive	Available grits	Main application	Max speed
STEELOX POLIFAN PFC (Pferd)	Zirconium corundum	40 / 60 / 80 / 120	Steel, light stainless steel	80 m/s
POLIFAN SGP (Pferd)	SG Zirconium corundum	40 / 60 / 80	Steel, stainless steel	80 m/s
Cubitron II 967A (3M)	Triangular ceramic grain	36 / 60 / 80	Steel, stainless steel, hard metal	80 m/s

Comparison: STEELOX POLIFAN PFC versus other market flap discs

The flap disc market is vast. To help choose, here is how the STEELOX POLIFAN PFC positions itself against its main competitors.

The STEELOX POLIFAN PFC is manufactured by Pferd. It features a zirconium-alumina grain and a flap design angled at 15°, optimized for grinding and deburring on steel and stainless steel.

Product	Manufacturer	Grain type	Flap angle	Target materials	Strong point
STEELOX POLIFAN PFC	Pferd	Zirconium-alumina	15°	Steel, stainless steel	High longevity, aggressive cut
Cubitron II 967A	3M	Precision-shaped ceramic	Variable	Stainless steel	Very high cutting speed
POLIFAN SG STEELOX	Pferd	SG-Zirconium	0° (flat)	Steel, stainless steel	Smoother finish, surface grinding
Flap Disc R822	Klingspor	Aluminum oxide	15°	Steel	Good quality/longevity ratio for entry-level
Tiger-Disc	Weiler	Ceramic	15°	Steel, cast iron	Heat resistance

Compared to classic aluminum oxide grain discs, the STEELOX POLIFAN PFC lasts significantly longer. The zirconium-alumina self-sharpens during use.

Compared to ceramic discs like the 3M Cubitron II, the STEELOX remains competitive on common steel, with a more controlled cost of use.

Pferd's PFC (Polifan Curve) format is distinguished by its curved design. It improves contact in angle grinding and reduces vibrations during long sessions.

Usage and safety tips for the STEELOX POLIFAN PFC

The STEELOX POLIFAN PFC is designed for angle grinders. Before mounting the disc, verify that your machine's maximum speed is compatible with that indicated on the disc.

Always mount the disc with the protective guard in place. Never remove this guard during use, this is a non-negotiable rule.

Work with an angle of attack of 15 to 30° relative to the surface. Too flat, and you lose efficiency. Too inclined, and you risk tearing the material and prematurely wearing the flaps.

Let the disc work without applying excessive force. Moderate and steady pressure yields better results and extends the life of the abrasive grain.

Systematically wear your PPE: safety glasses, gloves, dust mask, and hearing protection. Metallic particles are ejected quickly and are dangerous.

After use, store the disc away from humidity and impacts. A poorly stored disc becomes fragile and can break at the next startup.

The STEELOX POLIFAN PFC is reserved for machining non-alloyed and low-alloyed steel. Do not use it on stainless steel, aluminum, or stone, other products are provided for these materials.

FAQ - STEELOX POLIFAN PFC flap disc

1. What is the STEELOX POLIFAN PFC flap disc used for?

The STEELOX POLIFAN PFC is a flap disc designed specifically for working on steel. It allows for grinding, deburring, and surface finishing in a single pass.

2. On what materials can it be used?

It is optimized for non-alloyed and low-alloyed steel. Its abrasive is formulated to attack these metals efficiently without premature clogging.

It is not recommended for stainless steel or aluminum: other products in the POLIFAN range are intended for these materials.

3. What is the difference between the POLIFAN PFC and a standard flap disc?

The PFC (Polifan Fiber Compact) design combines a compact fiber structure with an optimized angle of attack. Result: a longer service life and more regular material removal than a standard flap disc.

Concretely, you use fewer discs on the same job.

4. Which grits are available?

The STEELOX POLIFAN PFC is available in several grits, typically from grit 40 (aggressive roughing) to grit 120 (finishing). The choice of grit depends on the initial surface condition and the expected finish.

5. Which grinder should it be used with?

It adapts to standard angle grinders equipped with an M14 mandrel. Common diameters are 115 mm, 125 mm, and 180 mm depending on the power of the machine.

Always verify that the maximum speed of the disc is compatible with the rotation speed of your grinder before use.

6. How to extend the disc's service life?

Work with an angle of attack of 15 to 30° relative to the workpiece. An angle that is too flat wears the flaps irregularly; an angle that is too vertical reduces the contact surface and overheats the metal.

Also avoid excessive pressure: let the abrasive work, the longevity of the STEELOX will do the rest.
