Precision Twist Drill 5999235 Jobber Drill Bit Wire 2 Hss

Product Description

The PRECISION TWIST DRILL 5999235 is a wire gauge size 2 (0.2210 inches) jobber-length drill bit manufactured from high speed steel (HSS) with a bright, uncoated finish. It features a standard 118-degree split point, a two-flute spiral configuration, and a web-thinned, tapered web design that reduces entry force and improves chip evacuation. The overall length is 3.875 inches, with a 2.625-inch flute length and a straight-cylindrical shank diameter of 0.2210 inches. This bit is suited for general-purpose drilling in production and maintenance settings and is sized to ANSI standards. Licensed tradespeople and machining technicians are the primary installers.

The 5999235 is designed for drilling into a wide range of materials including steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium. Its regular spiral type and 12xD flute-to-diameter ratio make it a practical choice for through-hole and blind-hole applications in both shop and field environments. Maximum drilling depth matches the flute length at 2.625 inches. The bit ships individually and is part of the R18P series, which covers the 0.2000-to-0.2500-inch decimal size range.

Key Features

• Wire gauge size 2 — 0.2210-inch decimal diameter, ANSI-compliant sizing
• 118-degree standard point angle for general-purpose entry into ferrous and non-ferrous materials
• Web-thinned, tapered web reduces thrust and improves chip flow
• High speed steel construction with bright uncoated finish — no coating to flake or delaminate
• Right-hand cut, two-flute spiral design with 2.625-inch maximum drilling depth
• Straight-cylindrical shank fits standard drill chucks without adapters

Compatibility

Designed as a general-purpose jobber-length drill bit compatible with any standard drill chuck accepting a 0.2210-inch straight-cylindrical shank. Rated for use in steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium workpieces per the manufacturer-listed primary workpiece material codes P, M, K, N, and S.

Installation Notes

Install in a keyed or keyless drill chuck and verify the shank is fully seated before operation. Machinists and maintenance technicians should confirm the workpiece is securely clamped and that spindle speed is appropriate for the material being drilled. Cutting fluid or coolant is not routed through this bit; use external lubrication when drilling harder alloys or stainless steel to extend tool life. Inspect the cutting edges before each use and replace the bit if chipping or dulling is observed.
