Centering drill bit Cimco 208832 Right hand rotation 1 pc

The Cimco 208832 centering drill bit is designed for accurate pilot-hole creation and precise positioning before drilling or machining. This single-piece tool with right-hand rotation provides a stable center mark and consistent starting point on a variety of materials. It is intended to reduce drill walking and improve hole concentricity when preparing workpieces for subsequent drilling or reaming operations.

Advantages

The centering drill bit delivers a defined centre point and stable seating that help prevent slips at drill start. Constructed as a single piece, it offers rigidity and reduced runout compared to multi-component options. Right-hand rotation matches standard drilling machines and ensures predictable cutting action and chip evacuation. The tool's geometry supports repeatable pilot hole locations and reliable alignment for follow-up drilling or threading.

Suitable for

• Marking and starting pilot holes in metal and non-ferrous materials
• Preparing workpieces for twist drilling, reaming or tapping
• Reducing drill walking on flat, round or irregular surfaces

Key specifications

• Rotation direction: right-hand
• Package quantity: 1 piece
• Tool type: centering drill bit (pilot/spotting drill)
• Construction: single-piece design for rigidity and reduced runout

How to use

Secure the workpiece to prevent movement and select an appropriate clamp or vice. Mount the centering drill bit in a drill chuck or machine spindle and verify firm clamping with minimal overhang. Align the tool with the intended hole position and apply light axial pressure at low speed to establish the centre dimple. Increase speed and feed according to material and drill size once the spot is formed. Use coolant or cutting fluid as appropriate for the work material to extend tool life and improve chip evacuation.

Usage recommendations

For best results, perform initial trials on scrap material to determine optimal speed and feed for the specific substrate. When working with hardened or abrasive materials, incorporate suitable lubrication and avoid excessive axial force to preserve tool geometry. Replace the tool if signs of chipping or significant wear appear to maintain hole accuracy.
