OSG Screw Machine Drill Bit 7/32 Inch, 120° Point Angle, 4 Facet Point - High Speed Steel Precision Drill Bit for Metal, Wood & Plastic - Perfect for DIY Projects, Metalworking & Home Repairs

These drill bits have a TiAlN coating that withstands high temperatures and protects the bits from wear during high-speed, dry machining applications with difficult-to-machine ferrous metals. Fast-spiral drill bits evacuate chips more quickly than standard spiral-flute drill bits as the bits drill into a workpiece.,High-speed steel screw-machine length drill bits provide more flexibility and absorb more shock and vibration than cobalt, powdered-metal, and carbide screw-machine length drill bits, making them suitable for use in manual drilling machines and handheld power tools. They may leave a rough finish on the hole. Screw-machine length drill bits are shorter than jobber length and maintenance length drill bits of the same size. Also called stub length drill bits, they provide more strength and rigidity and can drill straighter holes than longer drill bits. Their short length also allows them to access tight spaces where longer drill bits cannot fit.
