## Long description

Irwin 4.5 mm HSS Pro Long series model 10502487 is a high-speed steel twist drill designed for drilling metal and a range of general-purpose materials. The long-length geometry gives extended reach for deeper holes and helps improve chip evacuation during continuous drilling operations. The bit is compatible with handheld drills and drill presses, intended for maintenance, fabrication and repair tasks where extra reach and reliable hole quality are required.
Advantages
The HSS Pro Long construction provides good wear resistance and retains hardness at elevated cutting temperatures, supporting consistent performance when drilling through mild steel, non-ferrous metals and many general-purpose materials. The extended flute length enables deeper penetration without switching to extension tools, and the twist-flute design promotes efficient chip removal. Cylindrical shank fits standard drill chucks and the precision ground point helps center the bit for accurate starts and reduced walking.

How to use
Select an appropriate speed for the material being drilled and secure the workpiece to prevent movement. Clamp the drill bit in the chuck ensuring sufficient shank engagement. Use cutting fluid or coolant when drilling ferrous metals to reduce heat and prolong tool life. Apply steady pressure and allow the bit to cut without excessive force; withdraw periodically on deep holes to clear chips and maintain cooling. After use, clean the bit of chips and residue and store in a dry place.
Usage recommendations
For best results when drilling steel, use moderate spindle speeds and suitable cutting lubricant. When drilling thin or delicate workpieces, support the material to avoid deformation and consider a pilot hole to improve positioning accuracy.
