Quick summary: Type 27 depressed centre grinding wheel, 100 x 6.3 x 16 mm (4 x 1/4 x 5/8 inch). For both steel and stainless steel (STEEL+INOX). Maximum speed 15,300 r/min, oSa certified, compliant with EN 12413.

1. General information

• The PFERD E 100-6 PSF STEELOX grinding wheel is designed for rough grinding, weld seam grinding, bevelling and surface cleaning on carbon steel and stainless steel (INOX). The label states STEEL+INOX: one wheel covers both materials.
• The wheel contains fillers with a very low content of iron (Fe), chlorine (Cl) and sulphur (S). As a result, it does not contaminate stainless steel surfaces after grinding. This makes it suitable for stainless steel workshops with strict corrosion-resistance requirements.
• The PSF line is rated ★★☆☆ on PFERD's 4-star performance scale. It is a universal line that balances price and performance for everyday metalworking.
• The wheel carries the oSa mark of the Organisation for the Safety of Abrasives (osa-abrasives.org). It complies with the European standard EN 12413 and with USA ANSI B7.1 / OSHA regulations.

2. Benefits

2.1 Benefits for the plant

• No contamination of stainless steel, less rust after processing. Iron left on a stainless steel surface causes rust spots, and chlorine and sulphur increase the risk of pitting corrosion. Fillers with very low Fe/Cl/S content help stainless steel keep its corrosion resistance. This reduces cleaning and rework costs and lowers the risk of customer complaints.
• One wheel for both steel and stainless steel. A single item covers two materials. The plant stocks fewer SKUs, the store issues tools faster, and operators no longer pick the wrong wheel for the steel or stainless steel area.
• Calculate cost per job, not per wheel. The PSF line is moderately priced for everyday grinding. DAVITA recommends a trial run that compares how many wheels are used on the same length of weld seam. This is the most accurate way to measure real cost.
• Clear safety documentation. The oSa mark and the EN 12413 and ANSI B7.1 markings printed on the wheel give the HSE department a basis to approve the consumable. They also help meet customer or project owner requirements during plant audits.
• Complete documents. Each delivery comes with an invoice, certificate of origin (CO), certificate of quality (CQ) and user manual. These meet the requirements of project files, audits and purchasing procedures.
• Reliable supply from an authorised distributor. DAVITA restocks regularly and delivers fast, so the plant can keep its consumables inventory low.

2.2 Benefits for operators

• No need to stop and change wheels when switching materials. The wheel works on both carbon steel and stainless steel. On structures that combine both materials, operators keep grinding with one wheel without stopping the machine to change it.
• Grinding close to corners and edges. The depressed centre (Type 27) keeps the clamping nut below the wheel face. Operators can reach fillet welds, plate edges and tight spots without obstruction.
• Compact and light, reaches tight spots. The 100 mm wheel runs on a small, light angle grinder that is easy to handle in hidden corners, on small parts and when working at height.
• Peace of mind at work. The wheel meets EN 12413 safety requirements and carries the oSa mark. Combined with a wheel guard and proper personal protective equipment, operators work more safely.
• Fits common 100 mm angle grinders. The 16 mm bore fits the 100 mm angle grinders widely used in workshops.

5. Typical applications and usage notes

5.1 Applications

• Grinding weld seams and deburring on small parts, frames, handrails and stainless tubes.
• Grinding in hidden corners, tight spots and when working at height.
• Surface cleaning and rust removal; mechanical maintenance in plants.

5.2 Usage notes

• Use only on machines rated no higher than 15,300 r/min.
• Never mount the wheel on a machine whose speed exceeds the maximum speed on the label – for example, do not fit a larger wheel on a smaller angle grinder.
• Always use the machine's wheel guard. Wear eye or face protection, a dust mask, ear protection and gloves, as shown by the pictograms on the label.
• Hold the wheel at about 15°–30° to the surface. Do not use the grinding wheel for cutting.
• Before mounting, check that the wheel is free of cracks and chips, and is not damp or oily. Run it without load for about 30 seconds.
• Store in a dry place. Use the wheel before the expiry date stamped on the metal ring at the bore (EXP marking).
