JK Files Needle Files are precision hand tools designed for intricate metalworking, finishing, and fine shaping operations where standard engineer files cannot fit. Featuring integral cylindrical shanks for fine manual control, these precision files are engineered to provide accurate geometric control across a comprehensive range of cross-sectional profiles.
- Precision Machined Teeth: Cut pattern ensures consistent material removal rate and refined surface finish on small workpieces.
- Versatile Geometric Profiles: Available in multiple standardized cross-sections to match specific internal radii, angles, slots, and flat surfaces.
- Integral Cylindrical Shank: Round handle design allows for direct fingertip control during precise benchtop operations.
- Hardened Steel Construction: Crafted from high-carbon tool steel for long-term edge retention and wear resistance.
The JK Files needle file assortment covers standard precision profile options, including:
- Flat / Hand: Parallel or tapered rectangular cross-section for flat surfaces.
- Pillar: Narrow rectangular section for tight keyways and slots.
- Half Round: Flat face with a semicircular convex back for flat and concave surfaces.
- Three Square (Triangular): Equilateral 60° section for internal angles and corners.
- Square: Four-sided equal section for square holes and keyway filing.
- Round: Tapered circular section for deburring and opening rounded holes.
- Knife: Thin wedge section for acute angled grooves.
- Feather Edge: Rhombic section with thin edge profiles.
- Crossing / Oval: Double-convex section for double-curved interior shapes.
- Barrette: Triangular profile with cutting teeth on the flat face only for safe shoulder filing.
- Joint / Slitting: Flat profile with rounded edges.
