Crescent Hand File 08737NN 12 Inch Mill Bastard Tool (Single Cut American Pattern Tapered Point Machinists Steel Saw Sharpening Deburring Smoothing)

Crescent Nicholson 08737NN 12" Mill Single-Cut Bastard Hand File

The Crescent Nicholson 08737NN 12-inch mill single-cut bastard hand file dresses circular saw teeth, sharpens mill blades, trues machined alloy edges, and flattens weld seams without leaving gouge marks. Engineered from high-carbon industrial tool steel measuring 1.14 inches wide by 0.195 inches thick with an overall length of 14.5 inches, this American pattern machinist file delivers rapid stock removal paired with a smooth, satin-grade finish. Outfitted with uniform diagonal single-cut chisel teeth, dual square filing edges for uniform slot cleaning, and a body that tapers toward the point for confined access, it equips machinists, millwrights, toolmakers, and metal fabricators with precise control during heavy draw filing, deburring, and metal finishing operations.

Best Used For:

• Circular Saw and Mill Blade Sharpening: Dressing gullets and restoring razor-sharp cutting bevels on timber mill blades, circular saw discs, and crosscut handsaws.
• Machinist Draw Filing and Edge Truing: Gripping both file ends to draw the single-cut face along lathe turnings and flat metal bars for rapid stock leveling with a polished finish.
• Precision Slot and Keyway Cleaning: Deburring machined keyways, opening square grooves, and squaring inside 90-degree corners using the two parallel square-cut edges.

Key Performance & Safety Features

• Single-Cut Bastard Tooth Pattern: Precision-milled parallel rows of diagonal teeth provide aggressive material removal while generating a smooth, scratch-free surface.
• High-Carbon Tool Steel Hardness: Uniformly hardened steel body maintains tooth sharpness through prolonged filing across soft and medium-hard alloy metals.
• Dual Functional Square Edges: Parallel rectangular edges allow operators to file right angles and clean out keyway channels to uniform dimensions.
• Tapered Point Architecture: Width tapers slightly toward the point to enhance accessibility in narrow slots, keyways, and tight machinery clearances.
• American Pattern Engineering: Built to professional industrial standards for consistent metal removal rates and exceptional torsional rigidity.
• Integrated Tang Interface: Standard square tang accommodates universal file handles for ergonomic grip security and enhanced operator safety.

Technical Specifications

Pro-Tip: When draw filing machine parts to eliminate tool marks, apply blackboard chalk across the file teeth prior to use; chalking prevents metal filings from pinning between teeth, ensuring a smoother surface finish and extending file life.
