Centring drill for conical diamond core drills — 200 mm length, 10 mm shank (TECWERK)

The centring drill for conical diamond core drills is a precision pilot intended to stabilise conical core bits during drilling and to ensure accurate hole initiation in demanding applications.

• Precision pilot for conical core drilling
• 200 mm overall length for deep guidance
• 10 mm shank for secure mounting

Accurate pilot guidance for conical core bits

The centring drill delivers reliable pilot guidance for conical core drilling where stable entry is essential. With an extended 200 mm overall length, the pilot maintains alignment deep into the drilling run, reducing the risk of core drift and enabling consistent hole geometry. The design focuses on delivering mechanical stability and repeatability; this supports steady progress in drilling sequences and helps to reduce tool wear on the diamond core cutters used afterwards. The direct benefit is fewer aborted holes and a more predictable workflow during core extraction operations.

Secure mounting and straightforward handling

Designed with a 10 mm shank, the pilot guarantees straightforward mounting in standard chucks and adaptors commonly used with conical core drill assemblies. The compact shank diameter facilitates a stable connection while keeping the installation and removal process efficient. Operators benefit from reduced set-up time and improved centring speed when aligning the conical core bit, which in turn supports faster preparation between consecutive holes. Compatibility with diamond core systems makes this pilot a practical addition to any drilling kit where precise initial guidance is required.

Compatibility and application focus for diamond core drilling

Intended specifically for use with diamond core drills, the pilot serves as a targeted solution for initiating conical core operations. The geometry of the tool is optimised to work in series with conical core cutters, offering a dependable pilot to prevent lateral movement at start-up. This focus on application reduces the need for corrective rework later in the process and supports a higher first-pass yield on drilling tasks. Where conical core drilling is part of routine work, the pilot contributes to a smoother, more controlled drilling sequence.

FAQ

What is the primary purpose of this pilot drill? The centring drill provides a precise pilot bore to stabilise and guide conical diamond core drills during hole initiation, improving alignment and repeatability.

Which manufacturers' core cutters is the pilot intended to be used with? The pilot is designed for use with conical diamond core drills; compatibility depends on the core cutter's arbor and chuck configuration.

How does the 200 mm length improve drilling results? An extended length gives deeper guidance into the hole, reducing lateral movement of the core cutter and supporting more consistent hole geometry throughout the drilling process.

Is the shank size compatible with standard chucks? The 10 mm shank is suitable for standard fittings and adaptors used in conjunction with conical core drilling assemblies.

Can the pilot be used for non-diamond core applications? The tool is optimised for diamond core drilling; use with other systems should be evaluated for fit and suitability.
