Drill Bit Art-Pol AR54412 spiral 12 mm — twist drill for metal and wood

Spiral drill bit Art-Pol AR54412 with a 12 mm diameter is a twist-style cutting tool designed for general drilling operations in materials such as metal and wood. The drill features a spiraled flute that facilitates chip evacuation and a standard cylindrical shank compatible with handheld drills and drill presses. Its geometry supports straightforward drilling tasks in repair, construction and DIY projects where a 12 mm hole is required.

Advantages

The spiral flute design improves chip removal and reduces clogging during continuous drilling. A standardized cylindrical shank ensures secure clamping in common chucks and compatibility with a wide range of drilling machines. The 12 mm diameter provides a balance between hole size and structural integrity for typical fastening and passage needs. The twist-drill profile offers reliable centering and stable feed when used with appropriate speeds and cutting conditions.

Suitable for

• Drilling through mild steel and non-hardened metals (subject to drill material and cutting parameters)
• Boring holes in soft and hardwoods for fixtures and fasteners
• Repair and maintenance tasks requiring 12 mm holes
• General construction and DIY projects with standard handheld drills or bench drills

Key specifications

• Drill type: spiral (twist) drill
• Nominal diameter: 12 mm
• Shank style: cylindrical (straight) shank for standard chucks
• Flute: spiraled for chip evacuation
• Intended materials: metal and wood (performance depends on drill material and workpiece hardness)

How to use

Secure the workpiece and mark the drilling position. Clamp the 12 mm twist drill in the drill chuck, ensuring the shank is seated fully and tightened. Select appropriate spindle speed and cutting fluid if drilling metal; use lower speeds for harder metals and higher speeds for wood. Start drilling with moderate feed pressure, keeping the drill perpendicular to the surface. Retract periodically to clear chips when drilling deep holes and allow the tool to cool if it becomes hot.

Usage recommendations

Use cutting fluid or coolant when drilling metals to extend tool life and improve hole quality. For wood, use steady speed and avoid excessive pressure to reduce splintering. Inspect the drill for wear or damage before use and replace if the cutting edges are blunt or chipped.
