Value Collection 01198506 Cobalt Jobber Drill Bit No. 50

Product Description

The VALUE COLLECTION 01198506 is a cobalt jobber-length drill bit in wire gauge size No. 50, with a decimal diameter of 0.0700 inches. Built for heavy-duty drilling applications, this bit features a 135-degree split point that reduces walking on entry and lowers the thrust required to start a hole. The cobalt steel construction provides heat resistance well beyond standard high-speed steel, making it suitable for harder, more abrasive workpiece materials. With an overall length of 2 inches and a 1-inch flute length, this compact bit is sized for precision drilling in tight clearances. Machinists and metalworking tradespeople are the primary installers of this type of tooling.

This cobalt jobber drill bit is designed primarily for use in stainless steel and hardened materials where heat buildup and tool wear are common failure points. The right-hand, regular spiral flute geometry supports efficient chip evacuation in both handheld drill applications and drill press setups. The straight cylindrical shank with a diameter of 0.0700 inches is compatible with standard chucks sized for small-diameter tooling. Typical applications include precision metal fabrication, maintenance and repair operations, and production drilling where consistent hole diameter and edge quality are required.

Key Features

• Cobalt steel construction for heat resistance and extended tool life in hard metals
• 135-degree split point reduces drill walking and lowers entry thrust requirements
• Right-hand, regular spiral flute design promotes efficient chip evacuation
• Wire gauge No. 50 sizing at 0.0700 inches decimal for precision hole tolerances
• Straight cylindrical shank fits standard small-diameter drill chucks
• Heavy-duty grade rated for stainless steel and hardened material drilling

Compatibility

Designed as a standard jobber-length cobalt drill bit for use in handheld drills and drill presses equipped with chucks that accept straight cylindrical shanks in the small-diameter range. Rated for stainless steel and hardened workpiece materials as stated in product specifications.

Installation Notes

Installation of small-diameter drill bits should be performed by qualified machinists or metalworking tradespeople familiar with proper chuck tightening and spindle speed selection for cobalt tooling. Secure the shank fully in the chuck before operation to prevent slippage and bit breakage. When drilling stainless steel or hardened materials, use appropriate cutting fluid to manage heat and extend bit life. Inspect the cutting edges before each use and replace bits showing signs of heat discoloration beyond normal straw coloring or edge degradation.
