How to use

Select the Bosch HSS-G pilot drill bit and fit it securely into a matching hexagon socket adapter. Clamp the adapter in the power driver or holder so the bit is straight and stable. Start drilling at low speed to establish the pilot hole, then increase speed as appropriate for the material. Apply steady pressure and allow the bit to cut without forcing to avoid breakage or wandering.

Recommendations

Use cutting lubricant or appropriate speeds when drilling metals, and clear chips regularly. Replace the pilot drill if worn to maintain hole accuracy. Ensure the hexagon socket adapter and driver are rated for the intended torque and application.
