Sada vrtákov Cimco 201352

The Cimco 201352 drill bit set contains 19 high-quality twist drill bits designed for right-hand rotation. The set is intended to provide reliable drilling performance across a range of common materials. Each bit is ground to a standard geometry for accurate centring and straight drilling, and the set is suitable for workshop, maintenance and home-improvement tasks where consistent hole quality is required.

Advantages

This 19-piece drill bit set offers a balanced selection of sizes to cover frequent drilling needs without requiring individual purchases. The twist-drill design ensures efficient chip removal and stable cutting action when used with compatible chucks and correct speeds. Hardened and precisely ground flutes improve bit life and maintain hole accuracy over repeated use.

Key specifications

How to use

Select the appropriate drill bit size for the required hole and secure it in the drill chuck. Use correct drilling speed and feed for the material: lower speeds for harder metals and higher speeds for wood and plastics. Apply steady pressure and allow the drill bit to cut without forcing; retract periodically in metal to clear chips and reduce heat. Use cutting fluid when drilling harder metals to extend bit life and improve hole finish.

Recommendations

Store bits in their case to protect tips and maintain organization. Inspect bits for wear or damage before use and replace any that are chipped or excessively blunt. Match drill speed and use appropriate lubrication for metal work to optimise performance and prolong tool life.
