Pilot Drill for Diamond Hole Saws MODECO MN-61-246 10 mm

Pilot drill designed for use with diamond hole saws, MODECO MN-61-246 10 mm provides steady guidance and accurate centring when starting holes with diamond coring bits. Made to work with standard arbors, this pilot drill is intended to assist in precise hole-starting on surfaces commonly cut with diamond crowns, helping maintain alignment during coring operations.

Advantages

The 10 mm diameter pilot drill offers reliable tracking and reduced wandering at the start of drilling. Its compatibility with standard arbors ensures straightforward installation and fast replacement. The rigid design improves stability when coring through ceramic, porcelain, stone and similar materials, enabling a more consistent cut and reducing the risk of damage to the workpiece.

Suitable for

• Starting holes for diamond hole saws in ceramic and porcelain tiles
• Drilling openings in natural and engineered stone for plumbing fixtures
• Electrical installations requiring accurate hole positioning in wall and floor coverings
• General construction tasks where diamond coring is used and precise centring is needed

Key specifications

• Pilot drill diameter: 10 mm
• Designed for use with diamond hole saws and coring bits
• Compatibility: fits standard arbors for diamond crowns
• Intended materials: ceramic, porcelain, natural and engineered stone, similar hard surfaces
• Function: guidance and centring for hole-starting

How to use

Secure the pilot drill into the arbor according to the arbor manufacturer’s instructions, ensuring a firm fit. Position the diamond hole saw assembly on the marked drilling point and apply light pressure to engage the pilot drill with the surface. Start drilling at low speed to establish the centre, then increase speed and maintain steady, even pressure to complete the coring operation. Regularly clear slurry and debris to prevent clogging and overheating.

Usage recommendations

Use appropriate personal protective equipment, such as eye protection and gloves. For best results on brittle surfaces, consider wet cooling to prolong the life of the diamond crown and pilot drill. Inspect the pilot drill before each use and replace if worn or bent.
