DeWalt DW1909 9/64IN SPLIT POINT DRILL BIT

These general purpose high-speed steel jobber-length drill bits for metal and plastic have regular spiral flutes that are best suited for nonchipping hard materials such as nonferrous metals, cast iron, and structural steel.

• High Speed Steel drill bits absorb more shock and vibration than cobalt and carbide, making them suitable for use in manual drilling machines and handheld power tools.
• Black Oxide coating improves lubricity to reduce friction, minimize heat buildup, and improve wear resistance, chip flow, and tool life. It is a good choice for general purpose drilling and working with soft materials, such as plastic and low-carbon steel, and should not be used with aluminum and nonferrous metals.
• Jobber-Length drill bits are the most commonly used and provide a good balance of strength and accuracy when drilling into a variety of materials.
• Split Point drill bits are self-centering, requires less pressure to start, limits walking when used in stationary and portable drills.
• Spiral Flute drill bits are used in most general purpose holemaking applications to effectively evacuate chips as they drill into the workpiece.
• Hex Shank drill bits have six flat sides that prevent the bit from slipping in high-torque applications. Hex shanks install in standard drill chucks.
• 135 ° drill bits are used on harder materials like stainless steel or titanium.
