Precision Twist Drill 6001404 Taper Length Drill Bit

Product Description

The PRECISION TWIST DRILL 6001404 is a taper length drill bit designed for general-purpose drilling in a wide range of materials. It measures 0.2165 inches in diameter with a 118-degree standard point angle and a bright, uncoated high speed steel construction. The spiral flute geometry and web-thinned, tapered web design reduce thrust and improve chip evacuation. At 5.469 inches in overall length with a 3.594-inch flute length, it provides extended reach compared to a jobber-length bit while maintaining rigidity. The straight shank at 0.2165 inches diameter seats securely in standard drill chucks. This bit is suited for machinists, tool-and-die shops, and maintenance technicians working with production or repair drilling applications.

The 6001404 is built to DIN 340 specification, placing it in the taper length series 5ATL. It is appropriate for use in benchtop drill presses, CNC drilling operations, and handheld power drills wherever additional flute length is required to reach deeper hole depths. The 6xD flute-to-diameter ratio supports drilling in materials including carbon steel, alloy steel, stainless steel, cast iron, aluminum, brass, bronze, copper, nickel alloys, magnesium, and reinforced plastics. Right-hand cut geometry is standard for conventional clockwise-rotation spindles.

Key Features

• 0.2165-inch diameter with matching 0.2165-inch straight shank for direct chuck mounting
• 118-degree standard point angle with web-thinned, tapered web for reduced entry thrust
• Bright uncoated high speed steel construction — suitable for a broad range of ferrous and non-ferrous materials
• 3.594-inch flute length provides extended reach for deeper holes compared to jobber-length equivalents
• Right-hand spiral flute promotes efficient chip removal during through-hole and blind-hole drilling
• DIN 340 specification ensures consistent geometry and dimensional accuracy

Compatibility

Designed as a general-purpose taper length drill bit compatible with standard three-jaw drill chucks and collet systems accepting a 0.2165-inch straight shank. Suitable for use in drill presses, machining centers, and hand-held power drills with right-hand rotation.

Installation Notes

Installation is performed by machinists or maintenance technicians using standard drill press or CNC equipment. Ensure the shank is fully seated and the chuck is securely tightened before initiating spindle rotation. Inspect the cutting edges for wear or chipping before each use, as a damaged point will produce oversized or out-of-round holes. Use appropriate cutting fluid or coolant for the workpiece material to extend tool life, noting that this bit does not support coolant-through delivery.
