Precision Twist Drill 5999719 Taper Length Drill Bit

Product Description

The PRECISION TWIST DRILL 5999719 is a taper length drill bit designed for general-purpose drilling across a wide range of materials. Built from high speed steel (HSS) with a bright/uncoated finish, it measures 0.2210 inches in diameter and carries a 118-degree standard point angle. The spiral flute geometry and web-thinned, tapered web configuration improve chip evacuation and reduce entry resistance. With a straight shank and a 6xD flute-to-diameter ratio, this bit suits bench drill presses, hand drills, and machining centers where extra reach beyond a jobber-length bit is needed. It is sized to wire gauge #2 and follows ANSI standards.

This taper length bit is used in both shop and field settings where a longer flute length is required to reach depth or clear chips in deeper holes. The 3.75-inch flute length and 6.125-inch overall length provide added reach compared to standard jobber bits. It is appropriate for use in light manufacturing, maintenance and repair, HVAC fabrication, plumbing rough-in, and general metalworking. Right-hand cut geometry is standard for conventional drill press and hand drill operation.

Key Features

• High speed steel construction for durability across ferrous and non-ferrous materials
• 118-degree standard point angle for general-purpose entry on flat and curved stock
• Web-thinned, tapered web reduces thrust load and improves chip flow
• 3.75-inch spiral flute length provides extended reach versus jobber-length bits
• Straight shank compatible with standard drill chucks
• Bright/uncoated finish; ANSI-compliant Series R52

Compatibility

Suitable for drilling 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. Compatible with any standard drill chuck accepting a 0.2210-inch straight shank.

Installation Notes

Install in a standard keyed or keyless chuck rated for the shank diameter before applying power. Machinists and maintenance technicians should verify spindle speed is appropriate for the workpiece material and bit diameter before drilling. Secure the workpiece firmly to prevent movement during operation. Do not exceed the rated capacity of the drill press or hand tool being used.
