PFERD 83284 Singletwist Knot End Brush 1/4" Diameter .014 Stainless Steel Wire

The PFERD 83284 Singletwist knot end brush is a professional-grade stem-mounted power brush designed for precision surface conditioning, deburring, and cleaning operations in confined areas. This compact 1/4-inch diameter brush features a single twisted wire knot construction specifically engineered for accessing internal corners, edges, and tight spaces where larger brushes cannot reach.

Key Features:

• Single twisted wire knot design prevents unraveling during operation
• 0.014-inch diameter stainless steel wire filaments for aggressive material removal
• 1/4-inch shank fits standard die grinders and rotary tools
• 1-1/8-inch trim length provides optimal working surface
• Coated cup design prevents scratching or marking of workpieces
• Left-handed wire twist matches brush rotation to prevent knot loosening
• Maximum operating speed of 20,000 RPM
• 2-3/4-inch overall length for excellent control

Ideal for removing rust, scale, and corrosion from hard-to-reach areas on stainless steel, nickel-based alloys (Inconel, Hastelloy), and other demanding materials. The knotted wire construction allows adequate pressure application for efficient material removal while the stainless steel wire resists contamination of sensitive workpieces. Each box contains 10 brushes.
