Precision Twist Drill 5999149 Jobber Drill Bit 33 Hss

Product Description

The PRECISION TWIST DRILL 5999149 is a jobber-length drill bit sized at wire gauge 33 (0.1130 inches decimal) manufactured from high speed steel with a steam oxide coating. It features a 135-degree split-point tip for fast engagement and reduced walking on entry, making it well suited for drilling into steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium. The overall length is 2.625 inches with a 1.5-inch flute length and a straight-cylindrical shank. Two spiral flutes with a tapered web and web-thinned geometry evacuate chips efficiently during general-purpose drilling operations. Licensed HVAC techs, plumbers, electricians, and mechanical contractors reach for this size regularly when drilling through sheet metal, pipe hangers, brackets, and structural members.

This drill bit is intended for general-purpose drilling in both residential and commercial trade applications. It performs across a broad range of workpiece materials including carbon steel, stainless steel, cast iron, non-ferrous metals, and high-temperature superalloys and titanium. The right-hand spiral flute and 135-degree point angle keep it practical across production and service-call environments where a single bit must handle varied substrates. It conforms to ANSI standards and meets NAS 907 specification, making it appropriate for applications that require documented material and geometry compliance.

Key Features

• Wire gauge 33 diameter — 0.1130 inches — for precise small-diameter hole sizing
• 135-degree point angle reduces thrust force and minimizes bit walking on curved or hard surfaces
• Steam oxide coating provides mild corrosion resistance and reduces friction during cutting
• Web-thinned tapered web improves chip evacuation and lowers cutting resistance
• Right-hand cut with regular spiral flutes suits standard drill press and hand-drill operation
• Meets ANSI standards and NAS 907 specification for heavy-duty general-purpose drilling

Compatibility

Designed as a general-purpose jobber-length drill bit compatible with any standard drill chuck accepting a 0.1130-inch straight-cylindrical shank, including hand drills, drill presses, and right-angle drill attachments commonly used in HVAC, plumbing, and electrical trade work. Rated for use on steel, stainless steel, cast iron, non-ferrous metal, superalloys, and titanium workpiece materials per manufacturer specification.

Installation Notes

Install this bit into a properly sized chuck and tighten securely before operation. Use cutting fluid or lubricant when drilling stainless steel, superalloys, or titanium to extend bit life and manage heat. Keep drill speed appropriate for the workpiece material and bit diameter — smaller diameters generally require higher RPM and lighter feed pressure. Inspect the cutting edges for wear or chipping before each use and replace the bit if the point geometry is compromised.
