Drill pilot bit for tungsten hole saws GEKO G40000 pack of 100 CG40000A

These pilot drill bits are designed for use with tungsten (carbide) hole saws GEKO G40000 and are supplied as a pack of 100. Each pilot bit locates and guides the hole saw during cutting, helping to maintain centre alignment and improve control when starting and tracking the saw. The pilot shanks conform to standard arbor fittings so they are compatible with most hole saw arbors that accept standard pilot sizes. The pack format provides spare pilots for repetitive work and reduces downtime when bits wear or need replacement.

Advantages

The pilot bits are manufactured to provide consistent fit in hole saw arbors and stable guidance during drilling operations. Their design reduces wandering at drill entry and supports accurate hole placement. Supplied in a bulk pack of 100, they offer good value for workshops and production environments where frequent replacement is needed. The pilot bits are suitable for use with tungsten (carbide) hole saws, ensuring compatibility with carbide cutting tools.

Suitable for

• Guiding tungsten (carbide) hole saws in metalworking
• Starting and centring holes in wood and composite materials
• Production or renovation tasks requiring multiple pilot replacements
• Workshops and service centres using standard hole saw arbors

Key specifications

• Pack quantity: 100 pilot drill bits
• Compatibility: designed for use with tungsten (carbide) hole saws
• Shank type: standard pilot shank for common hole saw arbors
• Primary function: locating and guiding hole saws during drilling

How to use

Install the pilot bit into the hole saw arbor according to the arbor manufacturer’s instructions, ensuring the pilot is seated securely. Mount the hole saw and pilot assembly in a drill or drill press, set appropriate speed for the material and hole saw diameter, and start drilling with steady, controlled pressure. Use cutting fluid or coolant when drilling metals to reduce heat and extend tool life. Replace pilot bits as they become worn to maintain accurate guidance and safe operation.

Usage recommendations

For best results, match the pilot shank diameter to the hole saw arbor and use appropriate feed rate and coolant for the work material. Store spare pilots in a dry location and inspect for wear before reuse; replace damaged or bent pilots to avoid misalignment and excessive vibration.
