Accupro 10419 Solid Carbide Jobber Drill Bit 3/8 Inch

Product Description

The ACCUPRO 10419 is a solid carbide jobber length drill bit designed for precision drilling in demanding shop and field applications. It measures 3/8 inch (0.3750 inch) in diameter with a 150-degree standard point angle and a 4.25-inch overall length. The three-flute spiral design promotes chip evacuation and improves feed stability compared to conventional two-flute geometry. The bright, uncoated finish is suitable for a wide range of workpiece materials. Right-hand cutting direction and a straight cylindrical shank allow direct chuck mounting. This bit follows ANSI specification standards and is sold as a single unit.

This drill bit is suited for machinists, tool-and-die tradespeople, maintenance technicians, and fabricators working in production or MRO environments. The 5xD flute-to-diameter ratio supports deeper hole entry without excessive regrind cycles. At 3/8 inch diameter, it fits within the 0.3500 to 0.4000 inch drill bit size range, making it a common selection for tapped hole prep, clearance holes, and through-hole work in metal, composite, and similar materials.

Key Features

• Solid carbide construction for rigidity and long tool life in abrasive or hard materials
• 150-degree standard point angle reduces thrust and improves self-centering on entry
• Three-flute spiral design promotes faster chip evacuation compared to two-flute bits
• Bright uncoated finish maintains sharp edge geometry without coating buildup
• Right-hand cut with straight cylindrical shank for direct compatibility with standard drill chucks and collets
• ANSI specification designation ensures dimensional conformance

Compatibility

Designed as a jobber length drill bit compatible with standard drill chucks and collet holders accepting a straight cylindrical shank in the 3/8 inch diameter range, conforming to ANSI jobber length specifications.

Installation Notes

Install and remove this bit only with the machine fully powered down and the spindle at a complete stop. Secure the straight cylindrical shank firmly in a properly sized chuck or collet to prevent runout. Solid carbide tooling is brittle and can fracture if subjected to side loads or dropped on hard surfaces — handle with care during setup and storage. Always follow applicable shop safety standards and machine tool manufacturer guidelines when selecting speeds and feeds.
