Precision Twist Drill 5999626 Taper Length Drill Bit

Product Description

The PRECISION TWIST DRILL 5999626 is a taper length drill bit designed for precision drilling in a wide range of materials. Built from high speed steel with a bright uncoated finish, it measures 0.0135 inches in diameter and carries a 118-degree standard point angle. The straight shank and right-hand spiral flute geometry make this a general-purpose bit suited for machinists, tool and die technicians, maintenance mechanics, and fabricators who require accurate small-diameter hole work. The web-thinned, tapered web configuration reduces thrust and improves chip evacuation in tight tolerances.

This bit is intended for use in drill presses, CNC machining centers, and hand-held precision drills where wire gauge sizing is required. It corresponds to wire size number 80, making it a standard selection for instrument work, PCB drilling, small fastener clearance holes, and fine fabrication tasks. Suitable material applications include 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, and stainless steel. Sold individually per package with a minimum order quantity of 12 units.

Key Features

• High speed steel construction provides durability across a broad range of workpiece materials
• 118-degree standard point angle for general-purpose drilling applications
• Right-hand spiral flute with regular spiral type promotes consistent chip removal
• Web-thinned tapered web reduces cutting resistance and thrust load
• Straight shank compatible with standard drill chucks and collets
• Meets ANSI standards for dimensional accuracy and performance consistency

Compatibility

Designed as a general-purpose OEM-style taper length drill bit for use in standard drill chucks and collets accepting a 0.0135-inch straight shank; compatible with drill presses, CNC equipment, and precision hand-held drills configured for wire gauge tooling.

Installation Notes

Installation and use should be performed by qualified machinists or maintenance professionals familiar with small-diameter tooling. Secure the shank fully in the chuck or collet before operation and verify runout is within acceptable limits for the application. At this diameter, low feed pressure and appropriate spindle speed are critical to avoid bit breakage. Always disconnect power to the machine before changing tooling.
