Value Collection 01378223 Size 22 Cobalt Drill Bit

Product Description

The VALUE COLLECTION 01378223 is a screw machine length cobalt drill bit designed for heavy-duty drilling applications in metal fabrication, machining, and general shop work. Built from cobalt steel, this bit handles harder materials and higher heat than standard high-speed steel tooling. It measures 2.125 inches in overall length with a 1.0625-inch flute length, making it well-suited for close-quarter drilling where stub length is required. The 135-degree split point reduces walking and requires no center punch on most work surfaces. Cutting diameter is 0.1570 inches, corresponding to wire size 22. A right-hand cutting direction and regular spiral flute geometry provide efficient chip evacuation during operation.

This bit is appropriate for use in machine shops, production environments, and field fabrication where repeated drilling into steel, stainless, cast iron, or other hard alloys is required. The screw machine length profile fits standard drill chucks on benchtop drill presses, CNC machining centers, and handheld power tools. It is typically selected by machinists and metal fabricators who need a compact, heat-resistant drill bit for repetitive or precision hole-making in tough base materials.

Key Features

• Cobalt steel construction for improved heat resistance and durability in hard-material drilling
• 135-degree split point reduces thrust and eliminates the need for a center punch
• Screw machine length at 2.125 inches overall allows use in tight clearances
• Right-hand cut with regular spiral flute geometry for consistent chip removal
• Straight shank fits standard drill chucks without adapters
• Heavy-duty grade rated for demanding production and fabrication use

Compatibility

Designed as an OEM-style replacement or standard tooling addition for any drill press, handheld drill, or CNC spindle accepting a straight-shank drill bit at 0.1570-inch diameter in the screw machine length class.

Installation Notes

Installation is performed by machinists or metal fabricators following standard tooling practices. Secure the straight shank fully into the chuck and tighten with a chuck key before operation. Always power down and de-energize the machine before changing bits. Use appropriate cutting fluid or coolant for the base material being drilled to extend tool life, noting that this bit does not support through-coolant delivery.
