Precision Twist Drill Cobalt Jobber Length Bit

Precision Twist Drill Cobalt Jobber Length Drill Bits are twist drills for heavy-duty drilling in steel and other hard ferrous materials. The cobalt construction holds its hardness and toughness at high drilling temperatures. That gives it longer tool life than standard high-speed steel (HSS) drill bits. Jobber length (also called jobber drills or cobalt twist drills) is a general-purpose length for handheld drills, drill presses, machining centers, and lathes.

Key Features:

• Cobalt steel construction for extended tool life and heat resistance compared with standard HSS bits
• 135-degree point angle that penetrates hard material efficiently and produces smaller chips that are less likely to clog the hole
• Web-thinned, tapered web design for added strength and rigidity
• Right-hand cut, regular spiral flutes for general-purpose drilling
• Straight shank that fits standard drill chucks
• Heavy-duty grade built for demanding shop, fabrication, and maintenance work

Precision Twist Drill is a long-established maker of industrial cutting tools. These drill bits suit machinists, fabricators, and maintenance professionals who need reliable performance in tough materials such as steel and stainless steel.
