This drill bit adapter is machined with a Festool Centrotec-compatible shank so a standard round-shank twist drill can run directly from a Centrotec chuck. A collet inside grips the round shank; because it compresses, each adapter accepts a small range of bit diameters around its rated size. Available individually in six sizes.
- Available sizes: 1/8", 5/32", 3/16", 7/32", 1/4", and 3/8"
- Drive shank: Festool Centrotec-compatible
- Each size accepts drills within roughly +/-0.015" of the rated decimal size (for example, the 1/8" adapter accepts .111"-.126")
- Heat-treated for durability while retaining collet compressibility
Pick the adapter matching your round-shank bit's diameter, push it into your Centrotec chuck, and drill without an intermediate hex holder.
