Key specifications
 Material: High-speed steel (HSS)
 Diameter: 16 mm
 Overall length: 540 mm
 Quantity: 1 piece
 Intended use: Metalworking and hard material drilling
How to use
Fit the drill bit securely into a compatible drill chuck, ensuring adequate clamping length and concentricity. Select an appropriate cutting speed and feed rate for the workpiece material to avoid overheating; for harder metals reduce speed and use steady, controlled feed. Apply cutting fluid or lubricant when drilling ferrous metals to improve heat dissipation and prolong tool life. Clear chips regularly during deep drilling to prevent clogging and maintain cutting efficiency.
Usage recommendations
For best results, use the Proline HSS 16 mm bit with drills capable of maintaining stable RPM under load and with a suitable chuck clamping range. When drilling deep holes, periodically retract the bit to evacuate chips and apply cutting fluid. Avoid excessive side loads to prevent bending and premature wear.
