Centering drill bit Cimco 207590

The Cimco 207590 centering drill bit is a single-piece tool engineered for precision pilot drilling with a diameter of 6.35 mm. It provides accurate start points for subsequent drilling or machining operations, reducing bit wandering and ensuring consistent hole location. The construction and geometry of the bit are optimized for creating reliable pilot holes across a range of common materials, supporting both workshop and field use.

Advantages

This centering drill bit offers accurate centering and stable starts thanks to its single-piece design and precise point geometry. Its 6.35 mm diameter makes it suitable for standard pilot-hole workflows, while robust material and manufacturing quality deliver consistent performance and extended tool life. The bit's compact form factor simplifies handling and insertion into standard chucks or collets.

Suitable for

• Creating pilot holes before final drilling or tapping
• Center punching and spot drilling to prevent drill bit walking
• General workshop tasks on metal, wood and plastic where a 6.35 mm pilot is required

Key specifications

• Drill type: centering (spotting/pilot) drill bit
• Diameter: 6.35 mm
• Construction: single-piece solid design for rigidity
• Intended use: pilot hole creation and accurate centering
• Compatibility: fits standard drills and chucks accepting 6.35 mm shank

How to use

Secure the centering drill bit in the drill chuck or collet, ensuring firm and concentric clamping. Position the workpiece and align the bit over the intended center mark. Start drilling at low speed to establish the spot, applying light steady pressure until the center is formed; then increase speed or switch to the chosen final drill if required. Use appropriate cutting speed and lubrication based on the material being drilled to extend tool life and maintain hole quality.

Usage recommendations

For best results, use the bit to create a shallow pilot or center spot before using larger twist drills or taps. Select drill speeds and cutting fluid appropriate to the work material — lower speeds and cutting oil for harder metals, moderate speeds for softer metals and plastics, and higher speeds for wood. Inspect the bit for wear and replace when point condition degrades to maintain accurate centering.
