Drill Bit Art-Pol HSS cylindrical 12 mm AR53996

Art-Pol HSS cylindrical drill bit, 12 mm diameter, is a high-speed steel tool designed for drilling accurate holes in metal and a variety of other materials. The cylindrical shank fits standard chucks and bench drills, offering straightforward mounting and stable rotation. The HSS construction provides the hardness and heat resistance needed for routine workshop, maintenance, and light industrial tasks where a precise 12 mm hole is required.

Advantages

The HSS material ensures good wear resistance and thermal stability during drilling operations, reducing the risk of premature dulling when used within recommended speeds. The cylindrical shank provides compatibility with most standard drill chucks and simplifies tool changes. The 12 mm diameter offers a common size for through-holes, clearance holes, and pilot operations in sheet metal, plates, and similar materials.

Suitable for

• Drilling holes in steel and non-ferrous metals
• Workshop and general maintenance drilling tasks
• Bench drill and hand drill operations with standard chucks
• Creating precise 12 mm clearance or mounting holes

Key specifications

• Material: high-speed steel (HSS)
• Shank type: cylindrical
• Diameter: 12 mm
• Typical applications: metalworking, maintenance, general-purpose drilling

How to use

Select an appropriate drill holder or chuck that accepts a cylindrical shank and secure the drill bit firmly. Use recommended cutting speeds and feed rates for high-speed steel when drilling the target material, and apply cutting fluid when drilling tougher metals to reduce heat and extend tool life. Center the workpiece, clamp securely, and start at a low speed to establish the hole before increasing to the optimum speed. Clear chips regularly to prevent clogging and overheating.

Usage recommendations

For best results, match drilling speed to the material being cut (lower speeds for hard steels, higher speeds for non-ferrous metals), use appropriate cutting fluid for metalworking, and ensure secure clamping of the workpiece. Replace the bit if there is noticeable wear or chipping to maintain hole quality and operator safety.
