Import BDNA-C105424 Extra Length Drill Bit 3/8 in Hss

Product Description

The IMPORT BDNA-C105424 is an extra length high-speed steel drill bit designed for deep-hole drilling applications where a standard-length bit cannot reach. Built from high-speed steel with an oxide finish, this bit features a 3/8 inch diameter, a 12 inch overall length, and a 9 inch flute length that clears chips efficiently during extended cuts. The 118-degree standard point angle suits general-purpose drilling across a wide range of ferrous and non-ferrous materials. A web-thinned tip reduces thrust force at the start of each cut, and the right-hand spiral flute design moves material out of the bore as the bit advances.

This bit is suited for use in maintenance, fabrication, and trade service work where longer reach is required — such as drilling through structural members, deep flanges, or stacked materials. Electricians, plumbers, HVAC technicians, and general fabricators use extra-length bits when standard jobber drills fall short. The straight-cylindrical shank fits standard drill chucks without adapters. It is a general-purpose grade bit appropriate for moderate-production and intermittent drilling tasks in shop or field settings.

Key Features

• 3/8 inch diameter with 12 inch overall length for deep-reach drilling
• 9 inch spiral flute length for effective chip evacuation in deep bores
• 118-degree standard point angle for general-purpose use on ferrous and non-ferrous materials
• Web-thinned tip reduces entry thrust and improves hole-starting accuracy
• High-speed steel construction with oxide finish for wear resistance
• Straight-cylindrical shank compatible with standard drill chucks
• Right-hand cutting direction with regular spiral and 2-flute configuration

Compatibility

Designed as a general-purpose extra-length drill bit compatible with standard 3/8 inch or larger keyed and keyless drill chucks used in corded drills, drill presses, and magnetic base drills.

Installation Notes

Secure the straight-cylindrical shank firmly in the chuck before drilling and verify concentricity to avoid bit deflection on deep cuts. Use appropriate cutting fluid or lubricant when drilling steel or other ferrous materials to extend bit life and improve hole quality. Reduce feed pressure as the bit exits the workpiece to prevent grabbing or breakage. Wear appropriate eye protection per applicable safety standards when operating drilling equipment.
