Drill bit Art-Pol HSS straight shank 12 mm for metal, model 53420

High-speed steel (HSS) straight-shank drill bit Art-Pol 53420 with a 12 mm diameter is designed for drilling metal. The cylindrical shank ensures stable clamping in handheld chucks and drill presses. This solid HSS bit is intended for making through-holes and pilot holes in steel and other ferrous metals and is suitable for workshop, industrial and maintenance tasks where wear resistance and dimensional accuracy are required.

Advantages

The HSS material of the Art-Pol 12 mm drill bit provides high hardness and heat resistance during continuous drilling operations. The straight cylindrical shank offers reliable grip and easy mounting in standard chucks and drill presses. The geometry of the cutting edges and helix angle is optimized for cutting metal, reducing the risk of workpiece deformation and improving hole quality. The single-diameter design simplifies setup and tool changes.

Suitable for

• Drilling through-holes in steel plates and profiles
• Pilot holes for tapping and fastening operations
• Maintenance and repair tasks in workshops and factories
• Use with handheld drills and drill presses

Key specifications

• Material: high-speed steel (HSS)
• Shank type: straight / cylindrical
• Cutting diameter: 12 mm
• Intended material: steel and other ferrous metals
• Suitable mounting: standard chucks and drill presses

How to use

Secure the drill bit in the chuck ensuring straight alignment and sufficient clamping length of the shank. Select an appropriate spindle speed and feed for the workpiece material; lower speeds are recommended for larger diameters in hard steels to reduce heat build-up. Use cutting fluid or coolant when drilling ferrous metals to improve cutting performance and extend tool life. Apply steady, moderate pressure and periodically withdraw the bit to clear chips and prevent clogging.

Usage recommendations

For best results, match drilling speed and feed to the specific steel grade and use suitable cutting fluid. Inspect the bit for wear or chipping before use and replace when the cutting edges become rounded to maintain hole accuracy and reduce the risk of workpiece damage.
