Precision Twist Drill 6000233 Extra Length Drill Bit Hss

Product Description

The PRECISION TWIST DRILL 6000233 is a high-speed steel extra length drill bit engineered for deep-hole drilling applications where standard-length bits cannot reach. It measures 0.3594 inches in diameter with a 12-inch overall length and a 9-inch flute length, providing extended reach without sacrificing cutting performance. The 118-degree standard point angle and web-thinned tip reduce entry force and improve centering accuracy. The bright uncoated finish is appropriate for general-purpose drilling in a wide range of materials. Right-hand spiral flutes evacuate chips efficiently during through-hole and deep-hole operations. This bit is sized and specified under ANSI standards, making it a reliable choice for maintenance machinists, pipefitters, and fabricators.

This extra length drill bit is suited for drilling through thick stock, structural members, and assemblies where standard-length bits fall short. The 12xD flute-to-diameter ratio supports deep-hole work in aluminum, magnesium, copper, nickel, synthetic materials, titanium, stainless steel, malleable iron, and reinforced plastics. It is commonly used in industrial fabrication, mechanical contracting, and field maintenance settings where a single bit must penetrate full-thickness structural or pipe material. The straight-cylindrical shank seats securely in standard drill chucks and mill collets.

Key Features

• 0.3594-inch diameter with 12-inch overall length for extended reach drilling
• 9-inch flute length supports deep-hole chip evacuation
• 118-degree standard point with web-thinned tip for reduced entry force and improved centering
• High-speed steel construction with bright uncoated finish for general-purpose use
• Right-hand cut, regular spiral, 2-flute design for efficient material removal
• Tapered web configuration and ANSI-compliant dimensions for consistent performance

Compatibility

The 6000233 is a Series 1290 general-purpose extra length drill bit compatible with standard drill chucks and collets accepting a 0.3594-inch straight-cylindrical shank. Rated for use in aluminum, magnesium, copper, nickel, titanium, synthetic materials, stainless steel, malleable iron, nickel alloys, high-strength bronze, reinforced plastics, and steel.

Installation Notes

This bit is installed by machinists, pipefitters, and maintenance technicians using drill presses, magnetic drills, or hand drills with sufficient chuck capacity. Secure the straight-cylindrical shank fully in the chuck before operation to prevent slippage under the torque loads associated with a 12-inch bit. Use appropriate cutting fluid for the workpiece material to extend tool life and manage heat buildup. Inspect the cutting edges for wear before each use, as a dull tip on an extra length bit significantly increases deflection risk in deep-hole applications.
