Precision Twist Drill 6000288 Extra Length Drill Bit

Product Description

The PRECISION TWIST DRILL 6000288 is a high speed steel extra length drill bit designed for deep-hole drilling applications in metalworking and industrial maintenance environments. Measuring 0.2812 inches in diameter with an 18-inch overall length and a 13-inch flute length, this bit reaches depths that standard-length drills cannot. The 118-degree point angle and web-thinned tip reduce entry force and walking, making it well suited for production drilling and field repair work. The uncoated HSS construction provides consistent performance across a broad range of workpiece materials. Licensed machinists, maintenance mechanics, and industrial tradespeople are the typical installers of this tool.

This drill bit is intended for use in drill presses, lapping machines, and hand-held power drills where extended reach is required. It performs on aluminum, magnesium, copper, nickel, titanium, stainless steel, malleable iron, nickel alloys, hardened steel, high strength bronze, and reinforced plastics. The straight-cylindrical shank seats in standard drill chucks without adapters, and the right-hand spiral flute evacuates chips efficiently during deep-hole passes. It conforms to ANSI standards and carries a Series 1813 designation, indicating general-purpose grade performance.

Key Features

• 0.2812-inch cutting diameter with a matching 0.2813-inch straight-cylindrical shank for secure chuck retention
• 18-inch overall length and 13-inch flute length provide deep-reach capability at 15xD flute-to-diameter ratio
• 118-degree standard point angle with web-thinned, tapered web configuration reduces thrust and improves centering
• High speed steel construction, uncoated, supports a wide range of ferrous and non-ferrous workpiece materials
• 2-flute right-hand spiral with regular helix promotes efficient chip evacuation in deep holes
• ANSI-conforming Series 1813 general-purpose grade for consistent dimensional accuracy

Compatibility

Designed as a general-purpose extra length drill bit compatible with standard drill chucks accepting a straight-cylindrical shank of 0.2813 inches, suitable for use in drill presses and power drills across metalworking, maintenance, and fabrication applications.

Installation Notes

Installation and use of this drill bit should be performed by qualified machinists or tradespeople familiar with machine tool safety practices. Secure the shank fully in the chuck and verify runout before beginning any drilling operation. Use appropriate cutting fluid or coolant when drilling ferrous materials to extend tool life and maintain dimensional accuracy. Do not exceed the recommended feed and speed parameters for the workpiece material being drilled.
