Precision Twist Drill 6000247 Extra Length Drill Bit

Product Description

The PRECISION TWIST DRILL 6000247 is a 3/4-inch diameter extra length high-speed steel drill bit engineered for deep-hole drilling applications where standard-length bits fall short. With a 12-inch overall length and a 9-inch spiral flute, this bit delivers extended reach while maintaining chip evacuation efficiency. The 118-degree standard point angle and web-thinned tip reduce entry force and improve centering on a wide range of materials. The bright, uncoated finish is typical of general-purpose HSS tooling. A straight cylindrical shank measuring 3/4 inch in diameter seats securely in standard drill chucks. This bit is used by machinists, HVAC installers, electricians, plumbers, and fabricators who need reliable through-hole capability in tight or deep workpieces.

The 6000247 is rated for use in aluminum, magnesium, copper, nickel, synthetic, and titanium as primary workpiece materials under Series 1290 general-purpose classification. Secondary applications include stainless steel, hardened steel, high-strength bronze, malleable iron, nickel alloys, reinforced plastics, and magnesium alloys. The right-hand cutting direction and regular spiral configuration are standard for conventional drill press, hand drill, and CNC drilling operations. This bit suits trade professionals who need to drill through structural members, pipe hangers, conduit paths, or fabricated assemblies where a standard 6-inch jobber bit cannot reach.

Key Features

• 12-inch overall length provides extended reach for deep-hole drilling
• 9-inch flute length supports chip evacuation throughout the cut depth
• 118-degree standard point angle with web-thinned tip reduces cutting force and improves accuracy
• High-speed steel construction handles a broad range of metals, plastics, and composite materials
• Straight cylindrical 3/4-inch shank fits standard drill chucks without adapters
• Right-hand, regular spiral flute geometry compatible with conventional drilling equipment

Compatibility

Designed as an OEM-style general-purpose extra length drill bit compatible with any standard drill chuck accepting a 3/4-inch straight cylindrical shank, including drill presses, magnetic drills, and CNC machines. Primary workpiece materials listed by manufacturer include aluminum, magnesium, copper, nickel, synthetic, and titanium. Secondary materials include stainless steel, hardened steel, high-strength bronze, malleable iron, nickel alloys, reinforced plastics, and magnesium alloys.

Installation Notes

Secure the straight cylindrical shank firmly in the drill chuck before operation and verify runout is within acceptable tolerance for the application. Power down the drill completely before bit changes. Use appropriate cutting fluid or coolant for steel and stainless steel workpieces to extend tool life, noting that this bit does not feature through-coolant capability. Follow applicable shop safety standards and wear eye protection during all drilling operations.
