Precision Twist Drill 6000480 Taper Length Drill Bit

Product Description

The PRECISION TWIST DRILL 6000480 is a taper length high speed steel drill bit designed for precision drilling in a wide range of materials. It features a 1.00 mm (0.0394 inch) diameter with a 118-degree standard point angle and a bright, uncoated finish. The right-hand spiral flute geometry with web thinning and a tapered web configuration reduces cutting resistance and improves chip evacuation. The straight shank measures 0.0394 inches in diameter and seats securely in standard drill chucks. This bit is part of the Series 5ATL line and conforms to DIN 340 standards for taper length drills. Machinists, maintenance technicians, and trade professionals who require a general-purpose micro-diameter bit will find this a reliable option for close-tolerance work.

This drill bit is suited for drilling operations in both production and maintenance environments. Its 6xD flute-length-to-diameter ratio and taper length body provide extra reach compared to jobber-length bits, making it practical for deeper hole applications. It is rated for use in alloy steel, aluminum, aluminum alloy, brass, bronze, carbon steel, cast iron, copper, graphite, hardened steel, high strength bronze, magnesium, magnesium alloy, malleable iron, nickel, nickel alloy, reinforced plastic materials, stainless steel, and cermet. No coolant-through capability is present, so conventional flood or mist cooling applies where needed.

Key Features

• 1.00 mm (0.0394 inch) diameter taper length drill bit conforming to DIN 340
• 118-degree standard point angle with web-thinned, tapered web configuration for reduced entry force
• High speed steel construction for general-purpose performance across a broad material range
• Bright, uncoated finish suitable for use without additional surface treatment
• Right-hand cut, regular spiral flute for efficient chip removal
• Straight shank with no threading for direct chuck mounting

Compatibility

Designed as a general-purpose taper length drill bit for use with standard straight-shank drill chucks. Compatible with 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 workpieces.

Installation Notes

Installation is performed by machinists or maintenance technicians using any drill press, CNC machine, or handheld drill with a compatible straight-shank chuck. Secure the shank fully in the chuck before operation and verify concentricity to avoid runout at this small diameter. No coolant-through path is present, so apply external coolant or cutting fluid as required by the workpiece material. Inspect the cutting edges before each use, as micro-diameter bits are susceptible to tip chipping from improper handling or storage.
