Drill Bit Art-Pol HSS cylindrical 18 mm
Art-Pol HSS cylindrical 18 mm is a high-speed steel drill bit designed for metalworking and general drilling tasks. With an 18 mm cutting diameter and a cylindrical shank, this drill bit is intended for use in handheld drills and drill presses. The HSS material provides wear resistance and improved heat tolerance during continuous drilling operations in steel, iron and non-ferrous metals, making it suitable for workshop and maintenance applications.
The HSS construction offers good hardness and durability at elevated temperatures encountered during drilling in metals. The cylindrical shank ensures stable mounting in standard three-jaw chucks and drill chucks. Precision ground flutes promote efficient chip evacuation and consistent cutting performance. The 18 mm diameter provides a balance between hole size and rigidity for common metal fabrication and repair tasks.
Secure the drill bit in the chuck of a handheld drill or a drill press, ensuring the cylindrical shank is clamped tightly and the bit is aligned. Select an appropriate spindle speed for the material being drilled—lower speeds for harder steels, higher speeds for softer non-ferrous metals. Apply steady feed pressure and use suitable cutting fluid when drilling steel or other ferrous alloys to reduce heat and improve tool life. Periodically withdraw the bit to clear chips and prevent clogging of the flutes.
Use cutting fluid for prolonged drilling in ferrous materials, avoid excessive side load to prevent chipping, and inspect the cutting edges before use. Replace or re-sharpen the bit when wear or loss of cutting performance is observed to maintain hole quality and operator safety.
