Manufactured by GRAPHITE (model 57H881), this pilot bit centers and guides hole saws during drilling, ensuring accurate starts and reducing wandering.

## Long description

Drill Pilot Bit 10 mm for Diamond Hole Saws GRAPHITE 57H881 is a 10 mm pilot drill specifically made to work with diamond hole saws and compatible arbor assemblies. It provides a precise starting point for cutting, centers the hole saw on the workpiece and reduces lateral movement at the drill entry. The pilot is suitable for use on hard, brittle materials such as ceramic tile, glass, natural stone and other masonry surfaces when using a diamond hole saw.
Advantages
The 10 mm pilot bit offers accurate centering that helps prevent chipping and misalignment during hole saw drilling. Its construction is optimized for reliable guidance of the hole saw under rotary and wet drilling conditions. The compact diameter and straight shank design allow straightforward installation into many standard arbors and drill chucks, improving stability and repeatability of drilling operations.
Suitable for
 Starting holes for diamond hole saws when cutting ceramic tile
 Guiding hole saws in glass and mirrors with reduced wander
 Drilling openings in natural stone and engineered stone using diamond cups
 Wet or dry drilling setups that require a stable pilot in masonry materials
Key specifications
 Pilot diameter: 10 mm
 Intended application: guidance for diamond hole saws
 Compatible with standard straight-shank arbors and drill chucks
 Designed for use on ceramic, tile, glass and stone
 Suitable for rotary and wet drilling methods
How to use
Secure the pilot bit in the arbor or drill chuck following the arbor manufacturer's instructions. Position the pilot perpendicular to the work surface and start drilling at low speed to establish the center hole; once the pilot is engaged, increase speed moderately and apply steady pressure. For brittle materials such as tile or glass, use a consistent feed and, where recommended, coolant or water to reduce heat and prevent cracking. Withdraw occasionally to clear debris and maintain visibility of the cutting area.
Usage recommendations
Use appropriate safety equipment including eye protection and gloves. Match the pilot and hole saw sizes to the task and ensure the arbor and pilot are compatible before operation. For best results on glazed ceramics and glass, use water cooling and a low initial speed to avoid thermal shock.
