Accupro 10449 Solid Carbide Jobber Drill Bit 5/8 in

Product Description

The ACCUPRO 10449 is a solid carbide jobber length drill bit designed for precision hole-making in demanding production and maintenance applications. It measures 5/8 inch (0.6250 inch) in diameter with a 6 inch overall length and a 3-1/2 inch flute length. The 150-degree drill point angle and three-flute spiral configuration promote fast chip evacuation and accurate entry, particularly in harder workpiece materials. The bright uncoated finish is suitable for use across a broad range of metals and composites. A straight cylindrical shank provides secure seating in standard drill chucks and collet holders.

This drill bit suits machinists, toolmakers, and maintenance technicians working in metal fabrication, general manufacturing, and MRO environments. The 5/8 inch diameter falls within the 0.5000 to 0.6500 inch size range, making it a common selection for structural and mechanical drilling tasks. The regular spiral type and right-hand cutting direction are standard for conventional drill press, CNC, and hand-held power tool setups. No coolant-through capability means it is best suited to operations where flood, mist, or air cooling is applied externally.

Key Features

• Solid carbide construction for extended tool life in abrasive and hard materials
• 150-degree drill point angle for reduced thrust and self-centering entry
• Three-flute design improves chip clearance and feed rate capability versus two-flute geometry
• 3-1/2 inch flute length supports deeper hole applications within jobber length range
• Right-hand cutting, regular spiral suits standard clockwise-rotation machine setups
• Bright uncoated finish — no coating buildup concerns with aluminum or other soft metals

Compatibility

Designed as an OEM-style replacement or direct-use tooling for standard straight-shank drill chucks and collet holders accepting a 5/8 inch cylindrical shank, conforming to ANSI specification designation.

Installation Notes

Install and remove this bit with the machine fully powered down and the spindle at a complete stop. Secure the straight cylindrical shank fully in the chuck or collet to the recommended grip depth before tightening. Solid carbide is brittle compared to high-speed steel — avoid side loading, interrupted cuts without appropriate feed adjustments, or dropping the bit on hard surfaces. Apply adequate external coolant or cutting fluid during operation to manage heat and extend tool life.
