Precision Twist Drill 5999759 Taper Length Drill Bit

Product Description

The PRECISION TWIST DRILL 5999759 is a taper length, straight-shank 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 features a 118-degree standard point angle and a right-hand spiral flute with a regular spiral type. The 3/32-inch (0.0938-inch) diameter bit has an overall length of 4.25 inches and a flute length of 2.25 inches, giving it a 6xD flute-to-diameter ratio. The web is thinned and tapered for improved cutting action and reduced thrust during entry. This bit suits machinists, maintenance technicians, and trade professionals working with hand drills or drill presses.

The 5999759 is suited for drilling in a broad range of workpiece materials including alloy steel, carbon steel, stainless steel, cast iron, malleable iron, hardened steel, aluminum, aluminum alloy, brass, bronze, high strength bronze, copper, magnesium, magnesium alloy, nickel, nickel alloy, cermet, graphite, and reinforced plastic materials. It is appropriate for light fabrication, mechanical maintenance, and production drilling tasks in shop, field, or industrial environments where a longer-reach bit is required beyond what a jobber-length bit provides.

Key Features

• 3/32-inch (0.0938-inch) diameter with matching straight shank for standard chuck compatibility
• 118-degree standard point angle with web-thinned, tapered web for reduced cutting thrust
• High speed steel construction for durability across ferrous and non-ferrous materials
• Taper length body — 4.25-inch overall length with 2.25-inch flute — provides extended reach vs. jobber length
• Right-hand cut with regular spiral flute for efficient chip evacuation
• Bright/uncoated finish; no coolant-through required for general-purpose applications
• Meets ANSI standards; Series R51 general-purpose grade

Compatibility

Designed as a general-purpose taper length drill bit compatible with any standard 3-jaw drill chuck accepting a 3/32-inch straight shank. Suitable for use in hand drills, drill presses, and CNC drilling applications requiring extended reach in the listed material types.

Installation Notes

Secure the straight shank fully in the chuck and verify concentricity before drilling. Always wear appropriate eye protection and secure the workpiece before starting. Use cutting fluid or lubricant when drilling ferrous metals to extend tool life, even though no coolant-through channel is present. Replace the bit if the cutting edges show visible wear, chipping, or the drill begins to wander off center.
