61004 - PFERD 7-Inch PSF STEELOX Grinding Wheel Type 27

PFERD Universal Line PSF STEELOX Grinding Wheel

The PFERD 61004 is a 7-inch Type 27 grinding wheel from the Universal Line PSF, specifically engineered for the dual processing of steel and stainless steel (INOX). This "STEELOX" designation indicates a specialized formulation that is manufactured without the addition of ferrous, sulphurous, or chlorinated fillers. This purity is critical for industrial applications involving stainless steel, as it prevents the introduction of contaminants that could lead to corrosion or pitting after the grinding process is complete. For fabrication shops that handle mixed materials, this wheel provides a safe and efficient single-product solution.

Constructed with high-quality Aluminum Oxide abrasive grain, this wheel (Specification A 24 L PSF) features a coarse 24 grit and a medium-soft 'L' hardness bond. This combination allows for aggressive stock removal rates while maintaining a smooth grinding action. The softer bond is particularly advantageous as it allows the wheel to break down at a controlled rate, constantly exposing fresh, sharp abrasive grains. This self-sharpening effect ensures that the wheel cuts cool and fast, reducing the risk of heat discoloration on sensitive workpieces like stainless steel.

One of the key technical benefits of the PFERD PSF line is its efficiency on lower-powered drive systems. While it performs exceptionally well on high-output turbines and electric grinders, it is also designed to achieve high stock removal rates on low-power angle grinders. Operators do not need to apply excessive contact pressure to get the wheel to bite, which significantly reduces operator fatigue during extended grinding sessions. The 1/4-inch thickness provides a rigid, durable platform for heavy weld removal, chamfering, and edge grinding.

Applications:

• Weld seam removal on structural steel and stainless vessels.
• Chamfering and edge preparation before welding.
• Surface grinding and deburring of flame-cut parts.
• General fabrication in mixed-material environments.

By choosing the PFERD 61004, industrial MRO facilities benefit from a tool that balances durability with performance. The consistent quality of PFERD abrasives means fewer wheel changes, less downtime, and a lower total cost of operation per pound of metal removed.
