Drill bit Abraboro HSS cylindrical for metal 4 mm AB46804000
Abraboro HSS cylindrical drill bit for metal, 4 mm diameter, is designed for precise drilling in a variety of ferrous and non-ferrous metals. Manufactured from high-speed steel (HSS), this 4 mm metal drill bit offers reliable cutting performance and consistent hole quality when used in hand drills or drill presses. It is suitable for tasks that require accurate, repeatable holes with a clean finish and good edge integrity.
The HSS material provides high hardness and heat resistance during continuous drilling, reducing wear and maintaining cutting geometry. The cylindrical shank ensures secure clamping in standard chucks and supports stable rotation with minimal runout. The flute geometry is optimized for efficient chip evacuation when drilling metal, helping to avoid clogging and overheating. This drill bit delivers consistent 4 mm hole diameters and is compatible with both portable and stationary drilling equipment.
Fit the 4 mm Abraboro HSS drill bit into the drill chuck and secure it tightly to minimize runout. Mark the drilling point and, if necessary, use a center punch to prevent walking. Select an appropriate cutting speed and feed for the metal being drilled; start at a lower speed for harder materials and increase gradually if conditions allow. Use cutting fluid or lubricant when drilling steel or stainless steel to reduce heat and improve tool life. Clear chips frequently and allow the bit to cool between extended drilling operations.
For best results, match drill speed and feed to the workpiece material and use a suitable cutting fluid on tougher alloys; store the bit in a protective case or rack to prevent edge damage when not in use.
