Accupro 20385 Jobber Drill Bit Letter F Solid Carbide Tin

Product Description

The ACCUPRO 20385 is a jobber-length drill bit sized to Letter F (0.2570 inches) and manufactured from solid carbide with a titanium nitride (TiN) coating. The TiN coating increases surface hardness and reduces friction, extending tool life in production drilling applications. At 3.25 inches overall length with a 1.5-inch spiral flute, this bit is built for consistent, accurate hole-making in ferrous and non-ferrous metals, plastics, and composite materials. Three flutes provide improved chip evacuation compared to a standard two-flute design, making it well-suited for higher-feed-rate operations on machining centers and drill presses.

This bit is a fit for metalworking, fabrication, and general machining operations where tight tolerances are required. The 150-degree drill point angle reduces walking on entry and performs well in harder materials. The straight cylindrical shank seats securely in standard drill chucks and collet holders. Right-hand cutting direction is standard for conventional CNC and manual drill press setups. This is a professional-grade consumable used by machinists, tool-and-die shops, and metal fabricators working to ANSI standards.

Key Features

• Solid carbide construction for rigidity and heat resistance in demanding metal drilling
• TiN coating increases surface hardness and reduces tool wear
• 150-degree drill point angle for reduced walking and improved entry in hard materials
• Three-flute spiral design improves chip evacuation at higher feed rates
• Right-hand cutting, straight cylindrical shank fits standard chucks and collets
• Conforms to ANSI specification designation

Compatibility

Designed as a standard jobber-length drill bit for use in CNC machining centers, drill presses, and hand drills equipped with a compatible chuck or collet accepting a straight cylindrical shank in the 0.2500 to 0.3000 inch diameter range.

Installation Notes

Installation and use should be performed by a qualified machinist or tool operator familiar with proper chuck torque and runout requirements for carbide tooling. Always secure the shank fully in the chuck or collet before operation and verify spindle speed is appropriate for the material and bit diameter. Carbide is brittle — avoid side loading, interrupted cuts without proper setup, or dropping the bit on hard surfaces. Power down and lock out the spindle before changing or inspecting tooling.
