Precision Twist Drill 6000486 Taper Length Drill Bit

Product Description

The PRECISION TWIST DRILL 6000486 is a taper length drill bit designed for precision drilling across a wide range of materials in professional machining and fabrication environments. It measures 0.0472 inches (1.20 mm) in diameter with a 118-degree standard point angle and a bright, uncoated high speed steel construction. The straight shank and right-hand spiral flute design support consistent chip evacuation and accurate hole entry. With a flute-to-diameter ratio of 6xD and a web-thinned, tapered web configuration, this bit delivers controlled penetration in both manual and machine-fed applications. Machinists, toolroom technicians, and fabricators are the primary installers.

This taper length drill bit is suited for general-purpose drilling in production and toolroom settings where a longer flute than a jobber-length bit is needed for deeper reach. The extended flute length of 1-39/64 inches (41.00 mm) and overall length of 2-9/16 inches (65.00 mm) make it appropriate for drilling through-holes or deeper passages in workpieces where standard-length bits fall short. It conforms to DIN 340 specification, making it compatible with metric-standard tooling setups.

Key Features

• High speed steel construction provides durability across general-purpose drilling applications
• 118-degree standard point angle for accurate self-centering entry on flat and curved surfaces
• Bright, uncoated finish allows easy visual inspection for wear and resharpening
• Web-thinned, tapered web reduces thrust force and improves chip flow
• Right-hand spiral flute with 6xD flute-to-diameter ratio for extended reach drilling
• Conforms to DIN 340 specification for compatibility with metric tooling standards

Compatibility

Compatible material applications include alloy steel, aluminum, aluminum alloy, brass, bronze, carbon steel, cast iron, cermet, copper, graphite, hardened steel, high strength bronze, magnesium, magnesium alloy, malleable iron, nickel, nickel alloy, reinforced plastic materials, and stainless steel. Fits standard straight-shank drill chucks and collets accepting a 0.0472-inch (1.20 mm) shank diameter.

Installation Notes

This bit is installed by machinists and toolroom technicians in drill presses, CNC machines, or hand-held power drills equipped with an appropriately sized chuck or collet. Ensure the machine is fully powered down and the chuck is secure before changing tooling. Use cutting fluid appropriate to the workpiece material to extend tool life, particularly when drilling stainless steel, hardened steel, or nickel alloys. Inspect the cutting edges before each use and replace or resharpen when wear is visible to maintain hole quality and prevent breakage.
