Import 27418 Jobber Length Drill Bit 5.5 Mm Hss

Product Description

The IMPORT 27418 is a jobber-length twist drill bit designed for general-purpose drilling in metal, wood, and plastic. Built from high speed steel with an oxide coating, it delivers adequate hardness and surface protection for everyday production drilling tasks. The bit measures 5.5 mm (0.2165 inches) in diameter with an overall length of 3-47/64 inches and a flute length of 2-33/64 inches. The 118-degree standard point angle is the conventional grind for general shop and field use. A straight-cylindrical shank seats directly into standard keyless or keyed drill chucks. This bit is suited for use by machinists, pipefitters, electricians, and other trades requiring a reliable general-purpose drill in the 5 mm to 6 mm range.

This drill bit is appropriate for light to medium-duty drilling in ferrous and non-ferrous metals, thermoplastics, and wood substrates. It is commonly used in HVAC, plumbing, and electrical rough-in work where hole sizing must hit metric specifications. The jobber-length configuration balances reach and rigidity, making it a practical choice for handheld drill drivers and drill presses alike. The right-hand spiral flute efficiently evacuates chips during through-hole drilling.

Key Features

• 5.5 mm (0.2165 inch) diameter for metric-spec hole sizing
• High speed steel construction for general-purpose drilling in metal and non-metal materials
• Oxide coating provides corrosion resistance and reduced friction at the cutting edge
• 118-degree standard point angle for broad material compatibility
• Straight-cylindrical shank fits standard keyed and keyless drill chucks
• Web-thinned tapered web reduces thrust and improves chip clearing

Compatibility

Designed as a general-purpose jobber-length drill bit compatible with any keyed or keyless drill chuck accepting a 0.2165-inch straight-cylindrical shank, including handheld drill drivers and bench-mounted drill presses.

Installation Notes

Install the shank fully and securely into the chuck before drilling, and confirm the bit runs true before contacting the workpiece. Use appropriate cutting fluid or lubricant when drilling ferrous metals to extend bit life. Always wear eye protection and secure the workpiece to prevent rotation. Follow applicable shop safety standards and trade-specific codes when drilling into energized panels or pressurized assemblies.
