This HSS black oxide jobber length split point drill bit is designed for dependable, general-purpose drilling in metal, plastic, and wood. Manufactured from high-speed steel and finished with abrasion-resistant black oxide, it provides reliable performance for production, maintenance, and portable drilling applications.Featuring a precision-ground 135 split point tip, this bit delivers fast penetration and improved chip evacuation while the round shank offers compatibility with a wide range of drill chucks and tool holding systems.Manufactured from high-speed steel for general-purpose drillingBlack oxide surface treatment improves abrasion resistance and reduces friction135 Split Point Tip: Self-centering design reduces walking and eliminates the need for center punching in most applications.Jobber (standard) length for everyday drilling applicationsRound shank compatible with most drill chucks and tool holdersIdeal for drilling aluminum, brass, copper, steel, plastic, and woodManufactured using advanced production processes for consistent quality and durability.What It IsThis HSS black oxide jobber drill bit is designed for general-purpose drilling across a wide range of materials. It is well suited for use in maintenance, fabrication, production, and portable drilling applications.Material & ConstructionManufactured from high-speed steel (HSS), this drill bit provides a balance of toughness and wear resistance for everyday drilling tasks. The black oxide surface treatment enhances abrasion resistance and helps reduce friction during operation.135 Split Point PerformanceThe precision 135 split point geometry starts drilling immediately on contact and reduces walking. Sizes smaller than 1/16 have the 118 degree standard point. The flatter 135 angle is especially effective in harder metals where a standard 118 point may wander..Jobber Length DesignJobber length drill bits are the most common standard length used in drilling applications. This versatile length makes them suitable for a wide variety of tasks in both shop and field environments.ApplicationsCommonly used for:General metal drillingMaintenance and repair workFabrication and production drillingPortable drilling applicationsDrilling plastic and woodFrequently Asked QuestionsWhat is a black oxide drill bit user for?Black oxide drill bits are used for general-purpose drilling in metal, plastic, and wood. The black oxide finish helps improve wear resistance and reduce friction.What does split point mean?A split point drill bit features a 135 tip geometry that starts drilling on contact and reduces walking compared to standard 118 drill bits.What materials can this drill bit drill?This drill bit is suitable for aluminum, brass, copper, steel, plastic, and wood.What is jobber length?Jobber length refers to the industry-standard drill bit length. It offers a balanced combination of flute length and rigidity, making it suitable for most drilling applications.Is this drill bit suitable for stainless steel?While it can drill some stainless applications, cobalt drill bits are generally preferred for harder stainless steels.
