Precision Twist Drill 5997008 Drill Bit Wire 49 Hss

Product Description

The PRECISION TWIST DRILL 5997008 is a jobber-length drill bit sized to wire gauge number 49, equal to 0.0730 inches in diameter. It is manufactured from high-speed steel with a bright, uncoated finish and features a 135-degree split point for reduced walking on hard surfaces. The two-flute, right-hand-cut spiral design clears chips efficiently during through-hole and blind drilling operations. With an overall length of 2 inches and a flute length of 1 inch, this bit is suited for precision drilling in tight quarters. It carries an ANSI specification designation and is graded for heavy-duty general-purpose use.

This drill bit is intended for drilling operations in steel, stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and other hard materials. The straight-cylindrical shank seats securely in standard keyless or keyed drill chucks found on drill presses, CNC machines, and hand-held power drills used in machine shops, fabrication facilities, and maintenance environments. The web-thinned, tapered-web construction reduces thrust requirements when working in harder materials, making it practical for both production and repair applications.

Key Features

• Wire gauge size 49, 0.0730 inches diameter with matching straight-cylindrical shank diameter
• 135-degree standard point angle reduces drill walk on flat and curved workpieces
• Two-flute right-hand spiral with web thinning for lower thrust and cleaner entry
• High-speed steel construction, bright uncoated finish for general-purpose use
• Flute-to-diameter ratio of 14xD supports chip evacuation in deeper holes up to 1 inch maximum depth
• ANSI-compliant, heavy-duty grade, Series QC21P

Compatibility

Designed as an OEM-style replacement or standard jobber-length drill bit for use in any drill press, CNC machining center, or power drill equipped with a chuck accepting a 0.0730-inch straight-cylindrical shank.

Installation Notes

Installation is performed by machinists, toolroom technicians, or maintenance mechanics. Secure the shank firmly in a properly sized chuck before operating. Ensure the drill press or machine spindle is powered down and at a complete stop before inserting or removing the bit. Follow applicable shop safety protocols and ANSI B11 machine tool standards when setting up drilling operations.
