Precision Twist Drill 6000249 Extra Length Drill Bit

Product Description

The PRECISION TWIST DRILL 6000249 is a high speed steel extra length drill bit designed for deep-hole drilling applications across metal fabrication, maintenance, and industrial trades. The bit measures 3/8 inch in diameter with a 12-inch overall length and a 9-inch spiral flute, giving it the reach needed to drill through thick stock or deep assemblies that standard-length bits cannot access. A 118-degree standard point angle and web-thinned tip reduce thrust and improve penetration, while the bright uncoated finish suits general-purpose use across a wide range of workpiece materials. Right-hand cutting direction and a straight cylindrical shank allow use in standard drill chucks.

This bit is suited for drilling aluminum, magnesium, copper, nickel, titanium, synthetic materials, stainless steel, malleable iron, and high-strength bronze. The extra-length design fits production and field scenarios where standard jobber bits fall short, such as drilling through structural members, long-run assemblies, or fixture blocks. Machinists, pipefitters, ironworkers, and maintenance technicians working in industrial and commercial environments will find this bit appropriate for both drill press and handheld power tool applications requiring extended reach.

Key Features

• 12-inch overall length provides extended reach beyond standard jobber-length drill bits
• 9-inch spiral flute length for efficient chip evacuation on deep cuts
• 118-degree standard point angle with web-thinned tip reduces entry thrust
• High speed steel construction handles a broad range of ferrous and non-ferrous workpiece materials
• Straight cylindrical 3/8-inch shank fits standard drill chucks without adapters
• Right-hand cutting, regular spiral, tapered web — Series 1290 general-purpose grade

Compatibility

Designed as a general-purpose extra-length drill bit compatible with standard 3/8-inch or larger drill chucks. Suitable for drilling aluminum, magnesium, copper, nickel, titanium, synthetic materials, stainless steel, malleable iron, nickel alloys, magnesium alloys, reinforced plastics, and high-strength bronze per Series 1290 specifications. Meets ANSI standards.

Installation Notes

Secure the straight cylindrical shank firmly in a properly sized drill chuck before use and verify chuck tightness before beginning any cut. Power down and de-energize or lock out the drill press or handheld tool before changing bits. Use appropriate cutting fluid or lubricant when drilling ferrous materials such as stainless steel or high-strength alloys to extend tool life and reduce heat buildup. Dispose of metal chips safely and wear appropriate eye and hand protection per applicable shop safety practices.
