Precision Twist Drill 5998106 Jobber Drill Bit 71 Hss

Product Description

The PRECISION TWIST DRILL 5998106 is a jobber-length drill bit in wire gauge size 71, with a decimal diameter of 0.0260 inches. Made from high speed steel with a bright uncoated finish, it features a standard 118-degree split point and a two-flute regular spiral configuration. The straight cylindrical shank measures 0.0260 inches in diameter and 0.875 inches in length. Overall length is 1.25 inches, with a flute length of 0.375 inches. This bit is designed for general-purpose drilling applications and is well suited to HVAC technicians, electricians, plumbers, and machinists who need consistent, repeatable small-diameter hole production.

This drill bit is intended for right-hand cutting in a range of workpiece materials including steel, cast iron, non-ferrous metals, superalloys, and titanium. It fits standard drill chucks accepting straight cylindrical shanks of 0.0260 inches diameter. The general-purpose grade and ANSI specification make it appropriate for both production and field service environments where small wire-gauge holes are required. It is sold individually but is subject to a minimum order quantity of 12 units.

Key Features

• Wire gauge size 71 with 0.0260-inch decimal diameter for precise small-hole drilling
• 118-degree standard point angle with web-thinned, tapered web geometry for clean entry
• High speed steel construction for durability across ferrous and non-ferrous materials
• Regular spiral, two-flute design promotes efficient chip evacuation in short-flute applications
• Bright uncoated finish suitable for general-purpose use without specialized coolant requirements
• ANSI-compliant geometry in the R10H-R18H series for consistent dimensional accuracy

Compatibility

Designed as a general-purpose jobber-length replacement or standard drill bit for use in any drill press, hand drill, or CNC spindle accepting a straight cylindrical shank of 0.0260 inches diameter. Compatible with primary workpiece material codes P, K, N, and S as designated in the product specifications.

Installation Notes

Install this bit into a properly rated chuck, ensuring the shank is fully seated and the chuck is tightened securely before operation. Power down and de-energize all equipment before changing bits. Use appropriate cutting fluid or lubrication when drilling ferrous materials to extend bit life, though coolant-through capability is not applicable to this bit. Wear appropriate eye protection and follow shop safety protocols consistent with ANSI standards.
