Accupro 10451 Carbide Jobber Drill Bit 3/4 Inch 150 Deg

Product Description

The ACCUPRO 10451 is a solid carbide jobber length drill bit designed for precision drilling in demanding applications. Built from solid carbide with a bright uncoated finish, this bit delivers consistent performance in hard and abrasive materials. It features a 3/4 inch diameter, a 150-degree standard point angle, and a 3-flute spiral configuration with right-hand cutting direction. The overall length is 6 inches, with a flute length of 3.875 inches and a straight cylindrical shank. This bit is suited for machinists, toolroom technicians, and metalworking professionals who require tight tolerances and reliable tool life.

The ACCUPRO 10451 is used in production and maintenance machining environments where accurate, repeatable hole quality is required. Its 5xD flute-to-diameter ratio and regular spiral type make it appropriate for through-hole drilling operations in ferrous and non-ferrous metals. The 3-flute geometry improves chip evacuation compared to standard 2-flute designs, reducing heat buildup and improving surface finish in the bore. This bit is well-suited for CNC machining centers, drill presses, and manual mills operating in shop and industrial settings.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard materials
• 150-degree standard point angle for accurate self-centering entry
• 3-flute spiral design improves chip evacuation and bore finish
• Right-hand cutting direction compatible with standard spindle rotation
• Bright uncoated finish suitable for use with cutting fluids
• Straight cylindrical shank fits standard drill chucks and collet holders

Compatibility

Designed as an OEM-style replacement and standard tooling option for jobber length drill bit applications conforming to ANSI specification, with a 0.75 inch straight cylindrical shank compatible with standard drill chucks and ER collet systems.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Secure the straight cylindrical shank fully in the chuck or collet before operation and verify runout before cutting. Coolant-through is not supported on this bit, so apply cutting fluid externally when drilling ferrous metals to manage heat and extend tool life. Do not exceed the recommended feed and speed parameters for the workpiece material and machine spindle rating.
