The Crescent Nicholson® 21846NN is a high-performance 6-inch round bastard file designed for precision work in tight or curved spaces. Featuring a single-cut American pattern, this file is ideal for smoothing, shaping, and deburring circular openings, concave surfaces, and internal radii. Its round profile and tapered design allow it to reach areas that flat or rectangular files simply can’t.

Crafted from durable carbon steel, the 21846NN offers long-lasting performance and resistance to wear, making it a trusted tool for machinists, metalworkers, woodworkers, and DIYers alike. The bastard cut provides a coarser finish for faster material removal, while the single-cut teeth ensure smoother edges and greater control.

Key Features:

• American Pattern Round File: Designed for filing circular openings and concave surfaces with precision.
• Single-Cut Bastard Teeth: Offers light to moderate material removal with a smoother finish—ideal for shaping and refining.
• Tapered Design: Slight taper toward the tip improves access in narrow slots and tight contours.
• 360° Cutting Surface: Teeth are cut all the way around the file for full-surface filing capability.
• Safe Point Tip: Blunt end reduces the risk of injury and enhances control during detailed work.
• Durable Steel Construction: Made from hardened carbon steel for strength, longevity, and consistent performance.
• Compact Size: Perfect for toolboxes and portable kits—ideal for both professional and home use.
