Hilti developed dry diamond core drills and bits to be attached to a Hilti vacuum with a filter cleaning mechanism and 99% filter
efficiency. Hilti considers these coring applications to fit in, and be in compliance with, OSHA 1926.1153, Table 1, (vii) handheld and
stand‐mounted drills (including impact and rotary hammer drills).
Set-up
1. If using as rig‐mounted, attach the drill stand to the drilling surface using the appropriate anchoring accessories.
2. Attach the vacuum hose to the drill’s vacuum hose connector.
3. Insert the bit and ensure its tightened by turning the chuck to the closed position.
4. Start vacuum.
5. Verify proper operation of the dust collection system, including suction at the end of the bit.
• Check for damage or leaks in the vacuum, hose, and hose connector.
• See instructions for vacuum.
Drilling
1. Start the vacuum before beginning to drill.
2. Begin drilling, applying the required amount of pressure.
3. To maximize dust collection, after the hole is drilled, slowly withdraw bit from the hole, and keep the drill and vacuum running
until the bit is fully withdrawn.
