Import 27422 Jobber Length Drill Bit 7mm Hss Oxide

Product Description

The IMPORT 27422 is a jobber-length twist drill bit designed for general-purpose drilling in metal, wood, and plastic. It is manufactured from high speed steel with an oxide coating that provides basic lubricity and corrosion resistance during use. The bit measures 7 mm (0.2756 inches) in diameter and features a 118-degree standard point angle suited for drilling into a wide range of common materials. Overall length is 4-9/64 inches with a flute length of 2-7/8 inches. The straight-cylindrical shank fits standard three-jaw drill chucks without modification. This bit is used by machinists, pipefitters, electricians, and general tradespeople for production and maintenance drilling tasks.

The 27422 is appropriate for light-duty to medium-duty drilling applications in general shop and field environments. Its jobber-length body offers a balance between reach and rigidity, making it suitable for benchtop drill presses, hand drills, and magnetic drill setups. The right-hand spiral flute clears chips efficiently during through-hole and blind-hole drilling operations. Web-thinned geometry reduces entry thrust, which is useful when drilling by hand or in materials prone to work hardening.

Key Features

• 7 mm (0.2756 inch) diameter with a straight-cylindrical shank of matching diameter for secure chuck grip
• 118-degree standard point angle for general-purpose use across metals, plastics, and wood
• High speed steel construction provides heat resistance during continuous drilling cycles
• Oxide finish improves surface lubricity and offers basic protection against corrosion
• Web-thinned, tapered-web geometry reduces drilling thrust and prolongs cutting edge life
• Right-hand, regular spiral flute promotes efficient chip evacuation in standard drilling operations

Compatibility

Designed as a general-purpose jobber-length drill bit suitable for use in any standard three-jaw drill chuck accepting a 0.2756-inch straight-cylindrical shank.

Installation Notes

Secure the shank fully in the drill chuck and tighten all chuck jaws evenly before beginning any drilling operation. Always use appropriate cutting fluid or lubrication when drilling ferrous metals to extend bit life and reduce heat buildup. Wear safety glasses and secure the workpiece before applying drilling pressure. Inspect the cutting edges for wear or chipping before each use and replace the bit if the point is dull or damaged.
