Drill bit Proline 91326, metal, Ø13 mm, length 260 mm, 1 pc

Proline 91326 drill bit for metal, Ø13 mm and overall length 260 mm, is a single-piece drilling tool designed for making medium-diameter holes in metallic materials. The bit fits standard drill chucks and is suitable for handheld drill drivers and pillar drills for straight-through drilling. Constructed for workshop and construction use, this Proline drill bit combines a robust shank and a cutting geometry intended to provide accurate centered drilling with controlled chip removal.

Advantages

The Proline 91326 drill bit features a specially shaped solid carbide insert that increases durability and cutting performance while reducing load on the tool and the machine. A double-twist flute design promotes efficient chip evacuation and faster penetration. The overall geometry supports accurate centring and stable drilling through metal, helping to maintain hole quality over repeated use.

Suitable for

• Drilling medium-diameter holes in steel and other metals
• Workshop and fabrication tasks requiring accurate through-holes
• Construction-site metal fixing and installation work
• Use with drill drivers and pillar drills for straight-through drilling

Key specifications

• Diameter: 13 mm
• Overall length: 260 mm
• Material/feature: solid carbide insert on a single-piece design
• Flute type: double-twist for improved chip evacuation
• Intended application: drilling in metallic materials and compatible with standard drill chucks
• Quantity: 1 piece

How to use

Mount the drill bit securely in a compatible drill chuck, ensuring concentric clamping and correct seating of the shank. Select an appropriate cutting speed and feed rate for the specific metal being drilled, and use cutting fluid where required to reduce heat and improve tool life. Begin drilling with a steady, moderate feed to establish the hole, withdraw periodically if necessary to clear chips, and complete the through-hole in a controlled manner. After use, clean chips from the flutes and inspect the insert for wear before storage.

Usage recommendations

For best results when drilling metals, use appropriate coolant or cutting oil, select speeds matched to the metal hardness, and avoid excessive axial force to maintain centring and extend the life of the carbide insert.
