## Summary description

Irwin HSS drill bit for metal, 15.5 mm diameter, designed for drilling steel and other ferrous materials. The bit features a ground/parabolic tip for improved chip removal and stable centering. Suitable for use with drill presses and handheld drills in metalworking, maintenance, and fabrication tasks requiring precise through-holes.

## Long description

Irwin HSS drill bit for metal, 15.5 mm diameter, is designed to create precise through-holes in steel and other ferrous materials. The high-speed steel construction provides durability and heat resistance during continuous drilling. The parabolic, ground tip geometry improves centering and enables efficient chip evacuation to reduce clogging and maintain consistent cutting performance. This drill bit is compatible with drill presses and handheld drills used in metalworking, maintenance, and fabrication environments where accurate holes are required.
Advantages
The ground parabolic tip offers stable centering and reduces walking at the start of drilling, while the parabolic flute form enhances chip removal to lower friction and heat buildup. High-speed steel material balances toughness and hardness for good wear resistance and longevity in typical metal drilling tasks. The 15.5 mm diameter provides a mid-range size suitable for many structural and assembly applications, and the standardized shank fits common chucks on portable and bench-mounted drills.
Suitable for
Drilling holes in mild and medium carbon steels
Metal fabrication and assembly work
Maintenance and repair tasks on machinery and equipment
Use with drill presses and handheld drills for through-holes
Key specifications
Material: High-speed steel (HSS)
Tip geometry: Ground, parabolic point for improved centering
Diameter: 15.5 mm
Flute design: Parabolic flutes for efficient chip evacuation
Intended use: Drilling ferrous metals and steel
How to use
Select appropriate speed and feed rates for the material being drilled and ensure the workpiece is secured in a vice or clamped to prevent movement. Mark the drilling point and, if necessary, use a center punch to aid initial positioning. Fit the drill bit securely in the drill chuck, align perpendicular to the work surface where a straight hole is required, and begin drilling at moderate speed with steady pressure. Use cutting fluid or coolant when drilling harder steels or on prolonged runs to reduce heat and extend bit life. Periodically withdraw the bit to clear chips and inspect for wear.
Usage recommendations
For best results, match drill speed to the metal grade and use appropriate cutting lubricant. Replace the bit when wear reduces cutting efficiency or when chipping of the tip is observed to maintain hole accuracy and surface quality.
