Drill bit Artu 12 mm cylindrical shank universal (model 16712)

Artu universal drill bit with a 12 mm diameter and a cylindrical (straight) shank, model 16712, is intended for general drilling tasks in materials compatible with standard twist-drill geometry. The bit is manufactured for use in drills and drill presses that accept a 12 mm cylindrical shank. Its all-purpose design makes it suitable for routine workshop and construction work where a reliable, medium-diameter drill is needed.

Advantages

The 12 mm cylindrical shank provides secure seating in standard chucks and reduces runout when tightened correctly. The universal geometry offers good cutting performance across a range of common materials, delivering consistent hole quality for general applications. The straight shank allows use with keyed chucks, quick-change adapters, and drill presses without the need for additional shank modifications.

Suitable for

• Drilling medium-diameter holes in wood
• General-purpose drilling in metal sheets and profiles compatible with twist-drill bits
• Workshop and on-site construction tasks requiring a dependable 12 mm hole
• Use in handheld drills and drill presses with 12 mm cylindrical chucks

Key specifications

• Diameter: 12 mm
• Shank type: cylindrical (straight)
• Geometry: universal twist-drill style suitable for common materials
• Intended use: general-purpose drilling in wood, metal, and similar compatible materials

How to use

Secure the drill bit in a chuck that accepts a 12 mm cylindrical shank, ensuring the bit is tightened to minimize wobble. Select a drilling speed appropriate for the material being worked—slower speeds for harder metals, higher speeds for wood and softer materials. Apply steady, moderate feed pressure and allow the bit to clear chips periodically to prevent overheating. Use cutting lubricant when drilling metals to extend bit life and improve hole finish. After use, clean chips from the flutes and store the bit in a dry place.

Usage recommendations

Use protective equipment such as safety glasses and gloves. Match drill speed and lubrication to the material: use cutting oil for steel, and higher RPMs for wood. Inspect the bit for wear or damage before use and replace it if the cutting edges are dull or chipped to maintain hole accuracy and safe operation.
