Precision Twist Drill 6000230 Extra Length Drill Bit

Product Description

The PRECISION TWIST DRILL 6000230 is a high-speed steel extra length drill bit designed for deep-hole drilling applications where standard-length bits cannot reach. It measures 0.7188 inches in diameter with a 12-inch overall length and a 9-inch spiral flute, providing extended reach without sacrificing chip evacuation. The 118-degree standard point angle and web-thinned tip reduce entry force and walking on initial contact. Sold individually, this bit suits machinists, pipefitters, and fabricators who need reliable through-drilling in production or field environments.

The 6000230 is built for general-purpose drilling across a broad range of materials including aluminum, magnesium, copper, nickel, titanium, stainless steel, malleable iron, nickel alloys, hardened steel, high-strength bronze, and reinforced plastics. The straight-cylindrical shank seats securely in standard drill chucks, making it compatible with bench drill presses, magnetic drills, and hand-held power drills. Its uncoated bright finish is appropriate for use with cutting fluid on ferrous and non-ferrous workpieces alike.

Key Features

• 12-inch overall length with 9-inch flute for deep-hole reach in structural and fabrication work
• 118-degree standard point with web thinning for reduced thrust and cleaner entry
• High-speed steel construction withstands heat generated during extended cuts
• Right-hand spiral flute with regular helix promotes efficient chip clearing
• Straight-cylindrical shank fits standard drill chucks without adapters
• ANSI-specification compliance ensures dimensional consistency across production runs

Compatibility

Designed as a general-purpose extra length drill bit suitable for use in standard drill chucks on drill presses, magnetic base drills, and hand-held power drills. Primary workpiece materials include aluminum, magnesium, copper, nickel, synthetic materials, and titanium; secondary materials include hardened steel, high-strength bronze, magnesium alloys, malleable iron, nickel alloys, reinforced plastics, and stainless steel.

Installation Notes

Install in a properly rated drill chuck and confirm the shank is fully seated and tightened before operation. Apply appropriate cutting fluid for the workpiece material to extend tool life and prevent heat buildup during deep-hole drilling. Secure the workpiece firmly before drilling to prevent walking or chatter, particularly given the extended flute length. Always wear eye protection and follow applicable shop safety procedures when operating rotary cutting tools.
