Value Collection 01198225 Cobalt Jobber Drill No. 22

Product Description

The VALUE COLLECTION 01198225 is a cobalt jobber-length drill bit sized to No. 22 wire gauge, equivalent to 0.1570 inch decimal diameter. Built from heavy-duty cobalt steel, it features a 135-degree split point that self-centers on contact and reduces the thrust needed to start a hole, making it well suited for drilling into tough ferrous metals. The straw finish indicates heat-treated cobalt construction rather than a functional coating. With a 3.125-inch overall length and a 2-inch flute length, this bit fits standard drill chucks and drill presses used across metalworking and maintenance applications.

This drill bit is engineered for cutting stainless steel and hardened materials where high-speed steel bits wear prematurely. The cobalt alloy composition retains hardness at elevated cutting temperatures, reducing premature edge breakdown. It is commonly used in HVAC fabrication, plumbing rough-in, electrical panel work, and general metal fabrication where tight-diameter pilot holes or clearance holes are required. The right-hand spiral flute efficiently evacuates chips, keeping the cutting edge clear during extended drilling cycles.

Key Features

• No. 22 wire gauge size, 0.1570 inch decimal diameter for precise hole sizing
• 135-degree split point self-centers and reduces walking on smooth or curved metal surfaces
• Cobalt steel construction retains cutting hardness in stainless steel and hardened materials
• Right-hand regular spiral flute provides efficient chip evacuation
• Straight cylindrical shank fits standard three-jaw drill chucks without adapters
• Heavy-duty grade rated for demanding production and maintenance drilling cycles

Compatibility

Designed as a standard jobber-length drill bit compatible with any three-jaw drill chuck accepting a 0.1570-inch straight shank, including benchtop drill presses, hand drills, and magnetic base drills used in metal fabrication and trade service work.

Installation Notes

This bit is installed by a machinist, fabricator, or trade professional using a standard keyed or keyless drill chuck. Secure the straight shank fully in the chuck before use and confirm the bit runs true before engaging the workpiece. Use appropriate cutting fluid or coolant when drilling stainless steel or hardened materials to extend edge life and manage heat buildup. Note that coolant-through capability is not supported on this bit.
