Import BDNA--22453-1 1/2 Inch Hss Jobber Drill Bit

Product Description

The IMPORT BDNA--22453-1 is a jobber-length drill bit designed for general-purpose metal drilling in trade and shop environments. It measures 0.500 inches in diameter with a 6-inch overall length and a 4.5-inch flute length. The bit is manufactured from high speed steel with a gold oxide coating that provides lubricity and basic heat resistance during drilling operations. The 118-degree split point reduces walking on entry and allows drilling to begin without a center punch on most surfaces. Electricians, plumbers, HVAC techs, and general contractors will find this bit suited to everyday hole-making in steel, aluminum, and similar materials.

This bit is appropriate for residential and light commercial applications where a standard jobber-length drill bit is required. The straight-cylindrical shank seats securely in standard 3-jaw drill chucks on both corded and cordless drills. The right-hand spiral flute with regular spiral type efficiently evacuates chips during through-hole and blind-hole drilling. The Series 314 designation places it in a general-purpose category suitable for a wide range of common trade drilling tasks including conduit knockout prep, bracket mounting, and fastener clearance holes.

Key Features

• High speed steel construction with gold oxide coating for lubricity and corrosion resistance

• General-purpose grade suitable for steel, aluminum, and similar materials

Compatibility

Designed as a general-purpose jobber-length drill bit compatible with any standard drill chuck accepting a straight-cylindrical shank up to 0.500 inches in diameter.

Installation Notes

Secure the shank fully into the drill chuck before operation and verify the chuck key is removed. Always use appropriate eye protection and secure the workpiece before drilling. For ferrous metals, a cutting fluid or oil extends bit life and reduces heat buildup. Disconnect power from any drill press before changing bits or adjusting the table.
