OSG Jobber Length Drill Bit 13/64" - 120° Point Angle High Speed Steel (HSS) for Metal, Wood & Plastic Drilling - Perfect for DIY Projects & Professional Use

The WD1 coating on these drill bits is harder than a TiAlN coating, has excellent heat resistance, and protects the tool from wear when drilling into steel, stainless steel, hardened steel, and cast iron. The bits have fast-spiral flutes that evacuate chips more quickly than standard spiral-flute drill bits, and they have a straight shank that installs into a drill chuck or similar toolholder.,Non-coolant-through high-speed steel jobber-length drill bits do not have coolant holes, so a separate hose is required to bring coolant to the bits tip if it is needed. High-speed steel drill bits provide more flexibility and absorb more shock and vibration than cobalt, powdered-metal, 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. Jobber-length drill bits are the most commonly used drill-bit length. They provide a good balance of strength and accuracy when drilling into a range of materials.
