## Summary description

Proline drill bit model 91635, single-piece metal drill designed for drilling metal and similar materials. Diameter 16 mm and length 350 mm provide reach for deeper holes.

## Long description

Proline 16 mm x 350 mm model 91635 is a single-piece metal drill bit intended for professional and industrial applications. With a 16 mm diameter and 350 mm overall length, this drill bit provides extended reach for deeper holes in metal and similar hard materials. The design includes a specially shaped solid carbide insert to increase durability and improve centring, and a double-twist flute geometry for efficient chip evacuation and faster bore release. Supplied as a single unit, the bit is compatible with standard drill chucks and holders that accept its shank type and diameter.
Advantages
The specially shaped solid carbide insert enhances wear resistance and maintains cutting performance over extended use, resulting in more accurate centered drilling. Double twist flutes improve chip removal and reduce cutting load, which contributes to consistent drilling speed and reduced risk of jamming. The extended 350 mm length allows access to deeper drilling points while the 16 mm diameter provides a balance between hole size and structural rigidity.
Suitable for
Drilling holes in metal plates and profiles
Workshop and maintenance tasks requiring deeper penetration
Construction jobs where stable, straight holes in hard materials are needed
Key specifications
Diameter: 16 mm
Overall length: 350 mm
Material: solid metal body with solid carbide insert
Geometry: double-twist flute for chip evacuation
Quantity: 1 piece
How to use
Secure the drill bit in a compatible chuck or holder rated for the bit diameter and length. Use appropriate cutting speeds and feed rates for the material being drilled and ensure adequate clamping of the workpiece. For best results when drilling hard materials, apply steady pressure without forcing the bit and allow the carbide insert to do the cutting. Clear chips frequently to avoid clogging the flutes and overheating the bit.
Usage recommendations
Use cutting fluid or coolant when drilling metals to extend tool life and improve hole quality. Check chuck tightness regularly during extended operations and replace the bit if excessive wear or chipping of the carbide insert is observed.
