Drill bit Proline 71016 — metal drill bit Ø10 mm, length 160 mm, 1 pc

Proline 71016 is a single metal drill bit with a 10 mm diameter and an overall length of 160 mm, supplied as one piece. Designed for metalworking tasks, it fits handheld drills and drill presses and is intended for producing precise 10 mm holes in steel and similar hard materials. The drill’s length provides reach for deeper holes or when working through fixtures and plates, while compatibility with common drill chucks makes it suitable for workshop maintenance, fabrication and repair tasks.

Advantages

The Proline 71016 drill bit features a twist flute geometry that facilitates chip evacuation and helps maintain cutting efficiency during continuous drilling. Its 10 mm diameter and 160 mm length combination offers a balance between rigidity and extended reach for deeper metalwork. Supplied as a single, ready-to-use piece, the bit is compatible with standard handheld drills and drill presses used in industrial and professional environments.

How to use

Secure the workpiece to prevent movement, select an appropriate drilling speed for the material being drilled and install the 10 mm Proline 71016 drill bit into the drill chuck, ensuring firm clamping. Begin with a pilot mark or center punch on the intended hole position to reduce walking, start drilling at low speed to establish the hole, then increase speed as appropriate while applying steady, even pressure. Use cutting fluid or coolant when drilling tougher metals to extend tool life and reduce heat. After completing the hole, retract the bit while the drill is running briefly to help clear chips, then stop and inspect the hole for burrs.

Usage recommendations

For best results, match drill speed and feed to the specific metal being drilled, use cutting lubricant for stainless or hardened steels, and replace the bit if wear or excessive chatter reduces hole quality.
