How to Assemble Your Armeg C100 Heavy Duty 100mm Core Drill
Taper Drive Assembly
To set up your Armeg C100 Heavy Duty 100mm Core Drill with the taper drive system, start by inserting the CPD Pilot Drill into the core. Lock it in place using the DDR Drift Key.
Choose either the D100KHD or D250KHD drive adaptor, depending on the length required. If extra reach is needed, add an extension rod such as the E250K or E400K.
Then pick the correct adaptor for your tool. Use HB4K for SDS Plus or HMXX for SDS Max. This setup suits rotary drills with taper fittings.
Direct Drive Assembly
To use the direct drive system, insert the CPD Pilot Drill into the core and lock it with the DDR Drift Key. Then choose a fixed shank adaptor, such as D250MX or D470MX for SDS Max, or D175B4 / 9D300B4 for SDS Plus.
