Drill bit Proline 71426, HSS metal drill, Ø14 mm, length 260 mm, 1 pc

Proline 71426 is a single HSS metal drill bit with a 14 mm diameter and a total length of 260 mm. Intended for metal and other hard materials, this twist-style bit offers standard spiral geometry to create straight holes and is compatible with common drills and three-jaw chucks. Supplied as one piece, it is suitable for workshop, construction and repair tasks where a large-diameter metal drill is required.

Advantages

The HSS (high-speed steel) construction provides wear resistance and heat tolerance appropriate for repeated metal drilling. The 14 mm diameter and extended 260 mm length allow access to deeper holes without changing to extension accessories. Standard twist geometry promotes straight drilling and reliable chip evacuation, while single-piece supply simplifies ordering and inventory for professional or hobby use.

Suitable for

• Drilling through steel sheets and structural metal components
• Creating pilot or through-holes in thick metal plates
• Repair and maintenance work in workshops and construction sites
• Use with corded and cordless drills equipped with compatible chucks

Key specifications

• Material: High-speed steel (HSS)
• Diameter: 14 mm
• Overall length: 260 mm
• Geometry: Standard twist (spiral) flute design for chip evacuation
• Package quantity: 1 piece

How to use

Secure the drill bit in a drill chuck rated for the shank size and tighten firmly. Select an appropriate drill speed for the material being worked on; lower speeds are generally recommended for larger diameters in metal to reduce heat. Use cutting fluid or lubricant when drilling metals to extend bit life and improve chip removal. Apply steady, moderate pressure and withdraw periodically to clear chips when drilling deep holes.

Usage recommendations

For best results when drilling metal, use a drill with sufficient torque, maintain appropriate speeds for the 14 mm HSS bit, and apply cutting fluid. Inspect the bit for wear before use and replace if tip wear or damage is evident.
