Precision Twist Drill 5998216 Jobber Drill Bit 17 Hss

Product Description

The PRECISION TWIST DRILL 5998216 is a jobber-length drill bit sized to wire gauge 17 (0.1730 inches decimal) and manufactured from high-speed steel with a bright, uncoated finish. It features a standard 118-degree split-point angle, a regular spiral flute pattern, and a web-thinned, tapered web construction that reduces thrust and improves chip evacuation. Overall length is 3.375 inches with a flute length of 2.1875 inches. The straight-cylindrical shank diameter matches the drill diameter at 0.1730 inches, making it compatible with standard keyed and keyless drill chucks. This bit is part of the Series R10H-R18H and is intended for general-purpose drilling by machinists, maintenance technicians, and trade professionals.

This drill bit is suited for general-purpose drilling operations in steel, cast iron, non-ferrous metals, superalloys, and titanium. It is a right-hand cut, two-flute spiral bit designed for use in hand drills, drill presses, and CNC or manual machine tool setups. The 2.1875-inch maximum drilling depth covers the majority of standard jobber-length applications in production, maintenance, and field service environments. No coolant-through capability is present, so external coolant or cutting fluid is recommended when drilling harder materials.

Key Features

• Wire size 17 — 0.1730-inch decimal diameter for precise hole sizing
• 118-degree standard point angle for general-purpose entry on a wide range of materials
• High-speed steel construction with bright uncoated finish
• Web-thinned, tapered web reduces drilling thrust and improves chip flow
• Right-hand cut, two-flute regular spiral design for efficient material removal
• ANSI-compliant construction to Series R10H-R18H specifications

Compatibility

Designed for use in standard drill chucks accepting a 0.1730-inch straight-cylindrical shank. Suitable for drilling steel, cast iron, non-ferrous metals, superalloys, and titanium in general-purpose applications per the Series R10H-R18H specification.

Installation Notes

Secure the shank fully in the drill chuck before operation and verify chuck tightness to prevent slipping under load. Power down or de-energize the drill or machine tool completely before changing bits. Apply cutting fluid when drilling harder ferrous materials to extend bit life and maintain dimensional accuracy. Follow applicable shop safety procedures and machine tool manufacturer guidelines during operation.
