Product Description

Extra Length Aircraft Black Oxide Drill Bit for Applications in Light-Gauge Metal, Wood, Plastic

Descriptions of HSS Drill Bits For Metal:

• High-speed steel tools are good for most general purpose applications, offering a combination of hardness and toughness for wear resistance
• Black oxide treatment adds lubricity and creates small pockets on the surface of the tool that act to hold coolant near the cutting edge
• Round shanks allow use with a wide variety of toolholding systems
• When run in a counterclockwise direction (right-hand cut) spiral fluted tools evacuate chips up and out of the cut to reduce clogging
• For general purpose drilling in applications where extra length for reach is required, designed to perform in a broad range of materials in the iron and steel families
