Value Collection 01198456 Cobalt Jobber Drill Bit No. 45

Product Description

The VALUE COLLECTION 01198456 is a cobalt jobber-length drill bit sized to wire gauge No. 45 (0.0820 inches diameter). Built from heavy-duty cobalt steel with a straw finish, it features a 135-degree split point that reduces walking and lowers the thrust required to start a hole. The two-flute, right-hand spiral design evacuates chips efficiently during through-hole drilling. With an overall length of 2.125 inches and a flute length of 1.125 inches, it fits standard drill chucks via its straight cylindrical shank. This bit is suited for machinists, tool-and-die shops, and maintenance technicians who need consistent small-diameter drilling performance in demanding materials.

The 01198456 is designed primarily for drilling stainless steel and other hardened materials where standard high-speed steel bits wear prematurely. Its cobalt content improves heat resistance, making it appropriate for production drilling and repetitive-cycle applications without coolant flow through the bit. Typical install scenarios include fabrication shops, HVAC sheet-metal work requiring small pilot holes, and general maintenance drilling where wire-gauge sizing is specified. Sold individually, it is ordered in multiples of 12.

Key Features

• Cobalt steel construction with straw finish for heat resistance in stainless steel and hardened materials
• 135-degree split point reduces bit walking and entry thrust on hard surfaces
• Right-hand, regular spiral flute design for efficient chip evacuation
• No. 45 wire gauge size, 0.0820 inches diameter, fits standard straight-shank chucks
• Heavy-duty grade rated for production drilling without coolant-through requirement
• Compact 2.125-inch overall length suits tight-clearance drilling applications

Compatibility

Designed as an OEM-style replacement or direct-use jobber drill bit for any standard drill press, handheld drill, or CNC drilling station accepting a straight cylindrical shank in the 0.0820-inch diameter range.

Installation Notes

This bit is installed and removed by a licensed machinist or qualified technician using a standard keyless or keyed drill chuck. Always secure the workpiece before drilling and use appropriate cutting fluid when drilling stainless steel to extend bit life, even though this bit does not require coolant flow through its body. Inspect the split point for chipping before each use; a damaged point increases the risk of bit breakage in hard materials. Follow applicable shop safety standards and wear eye protection at all times during drilling operations.
