Centering drill bit Cimco 201354

The Cimco 201354 centering drill bit set contains 25 silver centering drills designed to create accurate pilot holes and starting points for larger drills or reamers. These centering drill bits are intended to provide stable, precise positioning on a variety of materials before main drilling operations. The set offers consistent geometry and a finish that facilitates reliable seating of drill tips and reduces walking during start-up.

Advantages

These centering drill bits are made with a durable finish that resists wear during repeated use and maintains cutting edges for consistent performance. The uniform sizes and geometry across the 25-piece set simplify selection for different pilot hole requirements. Their construction promotes stable starts, helping to reduce misaligned holes and improve overall drilling accuracy.

Suitable for

• Creating pilot holes for larger drill bits or taps
• Marking accurate centres on metal, wood, and plastics before drilling
• Use in drill presses, hand drills, and lathe tailstocks for centre drilling
• Precision layout work in metal fabrication and general maintenance

Key specifications

• Quantity: 25 pieces in the set
• Finish: silver surface treatment for wear resistance
• Type: centering/drill-start bits for pilot hole creation
• Typical applications: metalworking, woodworking, plastics
• Compatibility: suitable for hand drills, drill presses, and lathes

How to use

Select the centering drill bit size that matches the required pilot hole for the subsequent drill or fastener. Secure the workpiece and choose the correct drilling machine or hand tool. Use moderate speed and steady feed to start the hole, ensuring the centering drill seats before increasing pressure. After creating the pilot, remove the centering drill and proceed with the main drill or tapping operation. Maintain proper clamping and alignment for consistent results.

Usage recommendations

For best results, use cutting fluid when drilling metals to reduce heat and prolong tool life. Inspect bits regularly for wear and replace worn centering drills to avoid inaccurate starts. Store the set in a dry place to prevent corrosion and keep sizes organized for quick selection.
