Value Collection 01248863 Jobber Drill Bit 12.20mm Hss

Product Description

The VALUE COLLECTION 01248863 is a high speed steel (HSS) jobber-length drill bit sized at 12.20 mm (0.4803 inches) in diameter. It features a standard 118-degree split point geometry with a web-thinned, tapered web configuration that aids in center starting and reduces thrust on entry. An oxide coating provides mild lubricity and surface protection during drilling. With an overall length of 5-55/64 inches (5.8594 inches) and a flute length of 4-3/8 inches (4.375 inches), this bit is suited for general-purpose drilling in metal fabrication, maintenance, and production environments. Machinists, pipefitters, and ironworkers commonly reach for this size in daily shop and field work.

This drill bit is designed for general-purpose drilling in steel and cast iron workpieces. It fits standard drill chucks and is appropriate for use in drill presses, milling machines, and handheld power drills where a straight cylindrical shank is accepted. The 12.20 mm diameter places it in the 0.4000 to 0.5000 inch size range, making it a common selection for clearance holes, through-holes, and pre-tap operations in ferrous materials across both shop and field settings.

• High speed steel construction rated for steel and cast iron workpieces
• Oxide coating for mild surface lubricity and corrosion resistance
• Right-hand cutting, regular spiral flute with straight cylindrical shank for universal chuck compatibility
• Coolant-through: No — suited for dry or externally lubricated drilling applications

Compatibility

Designed as a general-purpose jobber drill bit compatible with any drill press, CNC machine, or handheld power tool equipped with a standard chuck accepting a 0.4803-inch straight cylindrical shank. Primary workpiece materials are steel and cast iron.

Installation Notes

Install in a properly sized drill chuck and tighten securely before operation. Secure the workpiece firmly to prevent movement during drilling. Follow applicable shop safety practices and employer-required PPE standards when operating drilling equipment. For best results in steel, use a cutting fluid or cutting oil at the drill point to extend tool life and improve hole finish.
