Product Description

Tungsten Carbide Rotary File - Cylindrical Milling Cutter, Single/Double-Flute Pattern (Type A) This Type-A rotary file combines the toughness of tungsten-carbide construction with precision-machined flute patterns for efficient metal grinding, carving, and deburring. Available in both cylindrical and ball-nose profiles, and in single- or double-flute versions, it's optimized for use in die grinders, rotary tools, and CNC carving machines.
 

Features

• Premium Tungsten-Carbide Body
  Built from solid carbide for exceptional hardness and wear resistance, ensuring long life even under heavy-duty carving and grinding tasks.
• Dual Profile Options
  • Cylindrical Shank: Ideal for flat-surface grinding and edge chamfering.
  • Ball-Nose Head: Perfect for sculpting, profiling, and finishing contoured surfaces.
• Single vs. Double Flute
  • Single-Flute (A1): Offers aggressive material removal and fast stock clearance.
  • Double-Flute (A2): Provides smoother finishes with reduced vibration, ideal for fine detailing.
• Type A Pattern
  Precision-cut flute geometry (straight or spiral) balances cutting efficiency with chip evacuation, minimizing clogging and heat buildup.
• Straight Shank Design
  Standard 6 mm or 1/4″ shank diameter fits most rotary tools and die grinders' collets for quick bit changes.

 

Applications

• Metalworking & Fabrication: Deburring weld seams, polishing edges, and removing slag from castings.
• Sculpture & Engraving: Carving intricate designs in steel, aluminum, brass, and other metals.
• CNC Carving: Precision profiling in automated engraving and milling machines.
• Tool & Die Maintenance: Refinishing mold cavities, restoring cutting edges, and trimming flash.
