Keskiöporanterä Cimco 208834

The Cimco 208834 centering drill bit is designed for precise pilot hole creation and accurate workpiece alignment before final drilling. This single-piece centering drill features a right-hand rotation and a compact geometry that helps establish a centered starting point on a variety of materials. The tool is intended to improve repeatability and reduce wandering when initiating holes, making subsequent drilling or reaming operations more reliable.

Advantages

The centering drill bit delivers stable performance thanks to its single-piece construction and rigid shank, which reduce vibration during start-up. Its right-hand rotation geometry and pointed tip produce a clear reference point for larger drills or taps, while the short length and compact design enhance control and prevent skate across the work surface. The bit provides consistent centering across repeated operations, contributing to improved accuracy and reduced rework.

How to use

Secure the workpiece and mark the intended hole location. Install the centering drill bit in the chuck of a drill press, hand drill or machine tool, ensuring the bit is clamped securely and aligned. Use moderate feed pressure and an appropriate spindle speed for the material being machined; begin drilling slowly to allow the tip to locate the center without walking. Once the centering hole is formed, remove the centering drill and proceed with the main drill or tapping operation using the established pilot.

Recommendations

Choose speeds and feeds suitable for the workpiece material and maintain coolant or light lubrication where applicable to extend tool life. Inspect the tip before use and replace the bit if the point is worn or damaged to maintain centering accuracy.
