Drill bit Proline 71692 — metal, Ø 16 mm, length 920 mm, 1 pc

Proline 71692 is a single metal drill bit with a 16 mm diameter and a total length of 920 mm, designed for drilling metal and other hard materials where a long reach is required. Supplied as one piece, this straight-shank bit fits machines that accept long drill bits and is intended for workshop or industrial environments that need deep or through holes in metal components. The tool's construction and geometry are aimed at maintaining stability during extended drilling operations.

Advantages

The drill bit combines a 16 mm cutting diameter with a 920 mm overall length to enable deep-hole drilling in thick metal workpieces without the need for extensions. Its straight shank design ensures compatibility with standard chucks that accept long bits. The geometry of the cutting edges supports efficient chip evacuation and consistent hole quality during prolonged use.

Suitable for

• Drilling deep or through holes in metal plates and structural components
• Workshop and industrial drilling tasks requiring extended reach
• Applications where a straight shank long drill is required for machine compatibility

Key specifications

• Material target: metal and similar hard materials
• Diameter: 16 mm
• Total length: 920 mm
• Shank type: straight shank suitable for chucks that accept long bits
• Pack quantity: 1 piece
• Cutting geometry: multi-flute/optimized geometry for chip evacuation

How to use

Select an appropriate drilling machine or drill press that accepts long straight-shank bits and secure the Proline 71692 bit firmly in the chuck. Mark the drilling position and, if necessary, pilot-drill or center-punch the workpiece to ensure accurate entry. Use steady, controlled feed pressure and appropriate spindle speed for metal of the given thickness and hardness. Periodically withdraw the bit to clear chips and prevent clogging; apply cutting fluid as needed to reduce heat and prolong tool life.

Usage recommendations

For best results when drilling metal, match spindle speed and feed to the material grade, use cutting fluid to improve cooling and chip removal, and avoid excessive side loads that can cause bit deflection. When drilling very deep holes, withdraw the bit frequently to clear chips and inspect cutting edges for wear.
