1/4" HSS SPIRAL 1MT TAPER SHANK DRILL BIT

These drill bits have a black-oxide finish that retains lubricants to improve the bits' wear resistance and chip flow.

• High-speed steel drill bits provide more flexibility and absorb more shock and vibration than cobalt and carbide drill bits, making them suitable for use in manual drilling machines and handheld power tools.
• They may leave a rough finish on the hole. These bits have spiral flutes that evacuate chips as the bits drill into a workpiece.
• High-speed steel tools are good for most general purpose applications, offering a combination of hardness and toughness for wear resistance
• Morse taper shank allows the tool to be inserted directly into the machine's spindle to facilitate high-torque applications such as large cut diameters
• When run in a counterclockwise direction (right-hand cut) spiral fluted tools evacuate chips up and out of the cut to reduce clogging
• They have a black oxide surface treatments that is abrasion resistant, reduces chip welding and improves chip flow
• S. Steel ANSI Morse Dimensions (production grade)
