Precision Twist Drill 6000220 Extra Length Drill Bit

Product Description

The PRECISION TWIST DRILL 6000220 is a high speed steel extra length drill bit designed for deep-hole drilling applications that standard-length bits cannot reach. With a 0.6562-inch diameter and a 12-inch overall length, this bit provides the extended reach needed for structural, fabrication, and maintenance work. The 9-inch spiral flute length promotes efficient chip evacuation, and the web-thinned, tapered web design reduces thrust and improves starting accuracy. The straight-cylindrical shank seats securely in standard drill chucks. This is a general-purpose bit suitable for a wide range of material types and is installed by machinists, maintenance technicians, and fabricators working with lathes, drill presses, or magnetic drills.

This bit is well suited to production and job-site drilling in aluminum, magnesium, copper, nickel, titanium, stainless steel, malleable iron, nickel alloy, high strength bronze, and reinforced plastic materials. The extra length design makes it the right choice when clearance is restricted or when holes must be drilled through thick stock or deep into a workpiece. Right-hand cutting direction and regular spiral type make this a straightforward drop-in for most drilling operations where a longer reach is required.

Key Features

• 0.6562-inch diameter with 12-inch overall length for deep-hole reach
• 9-inch spiral flute length for effective chip removal in deep cuts
• Web-thinned, tapered web reduces entry thrust and improves point stability
• 118-degree standard point angle for general-purpose drilling across multiple materials
• Uncoated high speed steel construction for compatibility with a broad range of workpiece materials
• Straight-cylindrical shank fits standard drill chucks without adapters
• ANSI-standard dimensions ensure consistent fitment and interchangeability

Compatibility

Designed as an ANSI-standard general-purpose extra length drill bit suitable for use with drill presses, magnetic drills, and hand drills accepting a straight-cylindrical shank. Primary workpiece materials include aluminum, magnesium, copper, nickel, synthetic, and titanium. Secondary workpiece materials include hardened steel, high strength bronze, magnesium alloy, malleable iron, nickel alloy, reinforced plastic materials, and stainless steel.

Installation Notes

Secure the shank fully in the drill chuck and verify runout before beginning the cut. Power down the drill and de-energize the machine before changing bits or adjusting chuck position. Use appropriate cutting fluid or coolant based on workpiece material to extend tool life, noting that this bit does not have through-coolant capability. Follow applicable shop safety standards and machine manufacturer guidelines for speed and feed settings when drilling with extra length bits.
