Drill bit Proline ZR58546 — 1 piece, standard twist drill

Proline ZR58546 is a single-piece standard twist drill designed for general-purpose drilling in materials such as metal, wood and plastic. Supplied as one compact unit, this drill bit is suitable for workshop use, repair kits and situations where a conventional twist drill is required. The geometry and dimensions of the bit follow typical standards for standard twist drills, making it interchangeable with common drill chucks and holders.

How to use

Secure the Proline twist drill in a suitable drill chuck and ensure the bit is tightened concentrically. Select appropriate spindle speed and feed rate for the material being drilled — lower speeds for harder metals and higher speeds for wood and plastics. Use cutting fluid or coolant when drilling metal to extend bit life and improve chip evacuation. Apply steady axial pressure without excessive force and withdraw periodically to clear chips if drilling deep holes.

Usage recommendations

For best results, match drill speed and lubrication to the work material, clamp the workpiece securely, and replace the bit when wear or chipping degrades hole quality. Use personal protective equipment such as safety glasses and gloves during drilling operations.
