Drill bit Proline 73310 — 10 mm diameter, 300 mm length, metal drill bit, 1 pc

Proline 73310 is a single metal drill bit with a 10 mm diameter and a total length of 300 mm, intended for drilling metal and creating long through-holes. Supplied as one piece, this Proline drill bit is compatible with standard drill chucks and is intended for workshop, repair and metalworking tasks that require a long 10 mm hole. The bit features rolled flutes and a sintered carbide cutting edge designed to improve cutting action and wear resistance, and it is delivered in a plastic case for safe storage and transport.

Advantages

The 10 mm diameter and 300 mm overall length provide reach for deep drilling and through-hole operations while fitting common chucks. Rolled flutes facilitate efficient chip evacuation during drilling, and the sintered carbide edge increases cutting durability and maintains edge sharpness when working with metal and certain building materials. Supplied as a single piece in a plastic case, the tool is simple to store and carry and is ready for immediate use in workshop or on-site conditions.

Suitable for (tasks / use cases)

• Drilling through-holes in metal sheets and plates
• Deep hole drilling where extended drill length is required
• Workshop and repair operations involving steel and other metals
• On-site metalworking and installation tasks requiring a 10 mm hole

How to use

Secure the drill bit in a suitable drill chuck, ensuring proper tightening and alignment. Select an appropriate drilling speed and apply steady pressure to start the hole; reduce feed when the bit encounters resistance to avoid overheating. Use cutting fluid or lubricant when drilling metal to extend tool life and improve cutting performance. After completing the hole, clear chips from the flutes and store the bit in its plastic case to protect the sintered carbide edge.

Usage recommendations

For best results when drilling metal, use moderate speeds, steady feed, and appropriate cutting fluid. Inspect the sintered carbide edge for wear or damage before each use and replace the bit when cutting performance degrades. The plastic case protects the cutting edge during transport and storage.
