Drill bit Proline 92221 — metal, Ø22 mm, length 210 mm, 1 pc

Proline 92221 is a single metal drill bit with a 22 mm diameter and a total length of 210 mm, supplied as 1 piece. Intended primarily for drilling in metal and other ferrous materials, this solid-design bit is suitable for through and deep-hole work in workshop, maintenance and construction environments. The geometry provides centered entry and steady cutting when creating larger-diameter holes in steel and similar materials.

Advantages

The Proline 92221 drill bit features a specially shaped solid-carbide insert that increases wear resistance and maintains cutting performance over extended use. Its design promotes accurate centered drilling and reduces axial loads on the tool and machine. The bit is supplied as a single-piece unit with a double-twist fluting that facilitates efficient chip evacuation during deep or through drilling.

Suitable for

• Drilling large-diameter holes in steel and other ferrous metals
• Workshop and maintenance drilling tasks
• Construction and installation where durable metal bits are required

Key specifications

• Material compatibility: steel and other ferrous materials
• Cutting tip: solid-carbide insert
• Diameter: 22 mm
• Total length: 210 mm
• Quantity: 1 piece
• Flute design: double-twist for improved chip removal

How to use

Secure the drill bit in a compatible chuck or tool holder rated for metal drilling and the bit diameter. Use appropriate drilling speed, feed and coolant for the material being drilled: lower speeds and steady feed are recommended for larger diameters in steel. Apply cutting fluid or coolant when drilling ferrous metals to reduce heat and extend tool life. Ensure clamping of the workpiece and use pilot holes if required for precise positioning before drilling the final 22 mm hole.

Usage recommendations

For best results, select drill speeds and feeds appropriate to the steel grade and thickness, use cutting fluid for cooling and lubrication, and clear chips regularly to avoid re-cutting. Inspect the carbide insert for wear and replace the bit when cutting performance declines to maintain hole accuracy and safety.
