Precision Twist Drill 6000211 Extra Length Drill Bit Hss

Product Description

The PRECISION TWIST DRILL 6000211 is an extra length high-speed steel (HSS) drill bit designed for deep-hole drilling applications where standard-length bits cannot reach. At 12 inches overall length with a 9-inch flute length, it gives tradespeople and machinists the reach needed to drill through thick sections, stacked materials, or hard-to-access workpieces. The 0.2656-inch diameter bit features a 118-degree standard point angle and a spiral, right-hand cutting flute with web thinning for improved chip evacuation and reduced thrust at entry. The uncoated bright finish suits a wide range of general-purpose drilling tasks.

This Series 1290 drill bit is suited for metalworking and fabrication environments where extended reach is a primary requirement. Primary workpiece materials include aluminum, magnesium, copper, nickel, synthetic materials, and titanium. Secondary materials include stainless steel, hardened steel, nickel alloys, malleable iron, high-strength bronze, and reinforced plastics. It is appropriate for use in machine shops, maintenance and repair operations, and field fabrication work where a portable drill or drill press is in use.

Key Features

• Extra length design at 12 inches OAL with 9-inch flute length for deep-reach drilling
• High-speed steel construction with bright uncoated finish for general-purpose metalworking
• 118-degree standard point angle with web-thinned, tapered web for reduced entry thrust
• Right-hand spiral flute with 2-flute configuration promotes efficient chip removal
• Straight-cylindrical shank at 0.2656 inches diameter fits standard drill chucks without adapters
• Meets ANSI standards; rated for aluminum, copper, titanium, stainless steel, and more

Compatibility

The 6000211 is a general-purpose Series 1290 extra length drill bit compatible with standard drill chucks that accept a 0.2656-inch straight-cylindrical shank. Suitable for use with drill presses, magnetic base drills, and portable power drills in metalworking applications.

Installation Notes

Secure the straight-cylindrical shank firmly in a keyed or keyless drill chuck before operation. Ensure the workpiece is clamped or fixtured to prevent movement during drilling. Use appropriate cutting fluid or coolant for harder secondary materials such as stainless steel or hardened steel to extend tool life and manage heat buildup. Allow the flutes to clear chips regularly when drilling deep holes to prevent packing and bit breakage.
