## Long description

Single metal drill bit Proline 14 mm x 300 mm model 91430, 1 pc is a long-reach straight drill intended for metalworking tasks requiring deep or through-hole drilling. With a 14 mm cutting diameter and 300 mm overall length, this single-piece bit fits standard drill chucks and is designed for workshop, construction, and maintenance use where extended reach and reliable centering are needed.
Advantages
The drill bit features a specially shaped solid carbide insert that increases durability and maintains cutting performance under heavy load. Its geometry delivers accurate centered drilling with reduced thrust, while a double twist flute promotes efficient chip evacuation for faster bore clearing. The long length provides access to deep holes without compromising bit stiffness for typical metal drilling applications.
Suitable for
Deep and through-hole drilling in steel and other metals
Workshop, maintenance and construction drilling tasks requiring extended reach
Use with standard corded and cordless drills equipped with compatible chucks
Key specifications
Cutting diameter: 14 mm
Overall length: 300 mm
Material: hardened tool steel body with a solid carbide insert cutting tip
Flute type: double twist for improved chip removal
Intended workpiece: steel and other metals (suitable for through and deep holes)
How to use
Secure the drill bit in a compatible drill chuck, ensuring firm clamping without over-tightening. Mark and center-punch the drilling point on the workpiece to improve initial positioning. Use appropriate drilling speed and feed rates for the metal being drilled, apply steady pressure, and allow the carbide tip to cut without excessive force. Periodically withdraw the bit to clear chips and prevent clogging of the flutes during deep drilling.
Usage recommendations
For best results, use cutting fluid or coolant when drilling steels to reduce heat buildup and extend tool life. Match drilling speed to material hardness, avoid excessive lateral forces, and inspect the carbide tip for wear before use to ensure accurate centered drilling.
