## Long description

Proline 91021 metal drill bit is a single-piece cutting tool with a 10 mm diameter and 210 mm overall length, intended for drilling metal and similar hard materials. The straight shank design fits handheld drills and drill presses, allowing use in through-hole drilling and preparatory metalwork in fabrication, repair and construction tasks. The bit is produced for professional and industrial applications and features a specially shaped solid carbide insert that improves durability and drilling accuracy.
Advantages
The carbide insert and solid construction provide increased wear resistance and consistent performance during extended use. Accurate centered drilling reduces wobble and helps achieve precise hole placement. The 210 mm overall length offers deeper reach than standard short bits while the straight shank ensures compatibility with common chucks. The bit is supplied as a single piece for easy selection and installation.
Suitable for
 Drilling through metal sheets, plates and structural components

How to use
Secure the drill bit in the chuck of a handheld drill or drill press, ensuring the straight shank is clamped firmly.

For clean holes and extended tool life, use cutting fluid or coolant when drilling thicker or harder metals. Clear chips from the hole periodically to prevent clogging and overheating.
Usage recommendations
Maintain appropriate drill speed and use cutting fluid for best results; inspect the carbide insert for wear and replace the bit if cutting performance degrades.
