Value Collection 78066578 Jobber Drill Bit 16.48mm Hss

Product Description

The VALUE COLLECTION 78066578 is a high speed steel jobber-length drill bit designed for general-purpose hole-making in steel and cast iron. It measures 16.48 mm (0.6490 inches) in diameter with a 7.125-inch overall length and a standard 118-degree split-point geometry with web thinning to reduce walking on entry. The oxide coating provides mild corrosion resistance and helps with chip evacuation during drilling. Two regular spiral flutes with a tapered web configuration handle material removal efficiently across a range of workpiece thicknesses.

This drill bit is suited for metalworking applications in fabrication shops, maintenance facilities, and industrial service environments. It is appropriate for drilling mild steel plate, structural steel, and cast iron components where a general-purpose HSS bit meets the job requirement. The straight cylindrical shank fits standard three-jaw drill chucks on floor-standing drill presses, magnetic base drills, and hand-held electric drills. Right-hand cutting direction is standard for all common rotary drilling equipment.

Key Features

• 16.48 mm (0.6490 inches) diameter with 5.203-inch flute length for deep hole capacity
• 118-degree standard point angle with web thinning reduces entry thrust
• High speed steel construction handles steel and cast iron without coolant-through requirements
• Oxide coating provides mild lubricity and corrosion resistance
• Regular spiral flute geometry promotes consistent chip evacuation
• Straight cylindrical shank fits standard three-jaw chucks without adapters

Compatibility

Designed as a general-purpose jobber drill bit for use in standard rotary drilling equipment accepting a straight cylindrical shank in the 0.6490-inch diameter range, suitable for steel and cast iron workpiece materials.

Installation Notes

Installation is performed by machinists, fabricators, or maintenance technicians using standard drill press or handheld rotary drilling equipment. Secure the shank fully in the chuck and verify concentricity before drilling. Use appropriate cutting fluid when drilling steel to extend tool life and improve hole finish. Always clamp the workpiece securely and wear eye protection in compliance with applicable shop safety standards.
