Precision Twist Drill 5998127 Jobber Drill Bit 35 Hss

Product Description

The PRECISION TWIST DRILL 5998127 is a jobber-length twist drill bit in wire gauge size 35, equivalent to 0.110 inches in diameter. Manufactured from high speed steel with a bright uncoated finish, it features a standard 118-degree split-point angle and a regular spiral flute designed for efficient chip evacuation. The straight cylindrical shank seats securely in standard drill chucks. This bit is part of the R10H-R18H series and is built for general-purpose drilling in production and maintenance applications where consistent hole quality and dimensional accuracy are required.

This bit is suited for drilling steel, cast iron, non-ferrous metals, superalloys, and titanium across a range of light to medium-duty applications. Its 1.5-inch flute length supports a maximum drilling depth of 1.5 inches, making it appropriate for through-hole and blind-hole work in sheet metal, structural components, and machined parts. It is commonly used by machinists, maintenance technicians, and fabricators working with standard drill presses, CNC machines, and hand-held power drills where a wire-gauge size 35 hole is specified.

Key Features

• Wire size 35 diameter at 0.110 inches for precise gauge-specified hole production
• High speed steel construction provides durability across steel, cast iron, and non-ferrous materials
• 118-degree standard point angle with web-thinned, tapered web for reduced thrust and cleaner entry
• Regular spiral flute with 2 flutes promotes consistent chip removal during drilling
• Bright uncoated finish allows easy visual inspection for wear or damage
• ANSI-standard geometry ensures compatibility with standard tooling and inspection gauges

Compatibility

Designed as a general-purpose jobber-length drill bit compatible with standard straight-shank drill chucks. Suitable for use in drill presses, CNC drilling machines, and hand-held power drills that accept a 0.110-inch straight cylindrical shank.

Installation Notes

Installation is performed by machinists or maintenance technicians familiar with rotary cutting tools. Secure the shank fully in the drill chuck and verify runout before use. Always wear appropriate eye protection and secure the workpiece before beginning drilling operations. Inspect the cutting edges for wear or chipping before each use and replace the bit if the point geometry is compromised.
