Precision Twist Drill 5999134 Wire Size 6 Hss Drill Bit

Product Description

The PRECISION TWIST DRILL 5999134 is a jobber-length twist drill bit in wire gauge size 6, equivalent to 0.2040 inches in decimal. Built from high-speed steel with a steam oxide coating, it carries a standard 118-degree split-point angle and a right-hand spiral flute for consistent chip evacuation. The overall length is 3.75 inches with a 2.5-inch flute length and a straight cylindrical shank measuring 0.2040 inches in diameter. This bit is part of the Series R18 line and is suited for general-purpose drilling in production and maintenance environments. Installation is handled by machinists, tool-and-die technicians, and maintenance mechanics.

This drill bit is designed for drilling into a broad range of workpiece materials including steel, stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and other hard materials. It is a general-purpose jobber-length bit well suited to bench drilling, drill press work, and handheld power tool applications in job shop, fabrication, and industrial maintenance settings. The 12xD flute-to-diameter ratio provides adequate flute length relative to bit diameter for standard through-hole and blind-hole applications. No coolant-through capability is present, so external cutting fluid is recommended when drilling harder alloys.

Key Features

• Wire gauge size 6 (0.2040 inches decimal) straight cylindrical shank for standard chuck compatibility
• 118-degree standard point angle with web-thinned, tapered web for reduced thrust on entry
• Steam oxide coating provides mild lubricity and corrosion resistance during storage and use
• Right-hand spiral flute with regular helix for efficient chip removal in ferrous and non-ferrous materials
• 2.5-inch maximum drilling depth with 2-flute geometry for general-purpose through and blind hole work
• Conforms to ANSI standards for jobber-length drill bit geometry

Compatibility

Designed as a general-purpose jobber-length replacement or stock drill bit compatible with any standard drill chuck accepting a 0.2040-inch straight cylindrical shank. Rated for steel, stainless steel, cast iron, non-ferrous metal, superalloys, and titanium workpieces per workpiece material codes P, M, K, N, and S.

Installation Notes

Install in a keyed or keyless drill chuck by a machinist or maintenance technician using standard chuck key procedures. Secure the shank fully and verify chuck runout before drilling. Power down and de-energize any machine tool before changing bits. Apply cutting fluid externally when drilling stainless steel, superalloys, or titanium to prevent work hardening and premature edge wear.
