Drill bit Proline 72260, metal drill bit, 22 mm diameter, length 600 mm, 1 pc

Proline 72260 is a single metal drill bit with a 22 mm diameter and a length of 600 mm, designed for drilling metal components where extra reach is required. The bit is supplied as one piece and is intended for use with drills or drill stands that can accommodate long drill bits. Its geometry suits work on sheet metal, profiles and structural elements in industrial and professional settings.

Advantages

The 22 mm diameter and extended 600 mm length allow access to deep or hard-to-reach holes while maintaining a stable cut. The double twist design facilitates efficient chip removal during drilling in metal. Manufactured for professional use, the bit provides consistent hole size and straightness when used with appropriate equipment and proper feed rates.

Suitable for (tasks / use cases)

• Drilling holes in sheet metal and metal panels
• Creating holes in profiles and structural metal elements
• Applications requiring extended reach or through-holes in metal assemblies
• Use with drill stands or handheld drills capable of handling long bits

Key specifications

• Material application: metal
• Diameter: 22 mm
• Overall length: 600 mm
• Delivery: single piece
• Flute type: double twist for chip evacuation

How to use

Mount the Proline 72260 drill bit in a compatible drill chuck or drill stand with sufficient clamping length and stiffness to support the 600 mm shaft. Secure the workpiece and mark the drilling position. Use appropriate cutting speed and steady feed pressure for metal drilling; apply cutting fluid where suitable to reduce heat and improve chip evacuation. Start drilling at low speed to establish the pilot, then increase speed within the drill and bit manufacturer recommendations. Withdraw periodically if chips accumulate to avoid clogging.

Usage recommendations

Use a drill or drill stand capable of rigid support and low runout for best accuracy. Select cutting fluid for the metal being worked, and check chuck clamping regularly. Avoid side loads on the long shaft to prevent bending and maintain straight holes.
