Precision Twist Drill 5997587 Jobber Drill Bit 7/64 in

Product Description

The PRECISION TWIST DRILL 5997587 is a jobber-length drill bit designed for general-purpose drilling in a wide range of materials. Built from high speed steel with a steam oxide coating, it measures 7/64 inch (0.1094 inches) in diameter with an overall length of 2.625 inches. The 118-degree standard point angle and web-thinned, tapered web geometry reduce entry force and improve centering on flat and curved surfaces. Two spiral flutes in a right-hand cut configuration clear chips efficiently during drilling. Licensed HVAC, plumbing, electrical, and mechanical trades rely on this type of bit for everyday installation and service work.

This bit is suited for drilling into steel, stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and other hard materials. The straight-cylindrical shank seats securely in standard 3-jaw chucks and keyed drill chucks found on hand drills, drill presses, and right-angle drills. With a flute length of 1.5 inches and a maximum drilling depth of 1.5 inches, it handles typical through-hole and clearance-hole drilling tasks encountered in residential and light commercial trade work. It conforms to ANSI standards and meets NAS 907 specification requirements.

Key Features

• High speed steel construction with steam oxide coating for corrosion resistance and reduced friction
• 118-degree standard point angle with web-thinned, tapered web for cleaner entry and improved bit life
• Right-hand cut, regular spiral flutes for efficient chip evacuation
• Straight-cylindrical shank compatible with standard drill chucks
• Conforms to ANSI standards and NAS 907 specification
• 14xD flute-to-diameter ratio provides rigidity for jobber-length applications

Compatibility

Designed as an OEM-style jobber-length drill bit compatible with any standard 3-jaw or keyed chuck accepting a 7/64-inch straight-cylindrical shank. Suitable for use across Series R10A, R15A, and R18A applications as designated by the manufacturer.

Installation Notes

Install this bit into a properly sized and tightened chuck before powering the drill. Ensure the workpiece is secured before drilling to prevent movement and bit breakage. Apply cutting fluid when drilling stainless steel, hardened steel, or superalloys to extend bit life and maintain cutting geometry. Replace the bit if tip geometry shows visible wear, chipping, or the bit no longer tracks true.
